On Arundo donax again

Hi again Could yo help me with this fungus on stems of Arundo donax? I think it is a bitunicate asco with shortly stipitate clavate asci, filamentous pseudoparaphyses and 3-septate brownish ascosporoes with neither gel seath, nor appendages. But the inmersed ascomata are oblong, as in Anthostoma cubiculare (only globose in frontal view), with an excentric obtuse and prominent papilla. I don't know a good genus for my fungus Thanks again for your kindly help

Hi forum These gregarious, superficial, small (200-250 microns in diam.), hairy perithecia were growing on a thin white subiculum on decorticated hardwood (Alnus?). The perithecia do not appear to react in KOH, or at least do not give a reddish or purple color. (Bionectriacee?) The bicellular ascospores maybe finelly verrucose. The perithecia are covered by a thick coat of yellowish hairs with finely spiny walls. No anamorph I have seen. Have you some idea for this collection? Many thanks again

Geopora

Hi forum This Geopora up to 50 mm in diameter, completely free and open, grew under Corylus avellana on a basic soil. The spores are ellipsoidal, always bigutulate, with obtuse rounded poles and with lateral walls tending to be parallel. No key to the genus has been satisfactory to me in attempting to resolve this collection and only Benkert's key (Z. Mykol., 2010) offers me the possibility of Sepultaria veselskyi Svrcek, a smaller carbonicolous species. Do you have any ideas that could help me? Many thaks in advance

Lasiobolus vs Trichobolus

Hello forum Tiny apothecia growing in incubated deer dung. The hairs had any septa and the dextrinoid reaction of the hairs is inconsistent but sometimes present especially towards the base. The elongate ascospores do not seem fit well with the broadly ellipsoidal or subspherical ones described by Marchal for Lasiobolus (Lachnea) lasioboloides, but the absence of septa seems more characteristic of Lasiobolus than of Trichobolus deextrinoideosetosus.

Cyathicula complicata?

These shortly stipitate brownish apothecia grew on decorticated brances of Acer pseudoplatanus still attached to the tree at 1300 m of altitude. I think it fits well with the Karsten's and Carpenter's concept of Cyathicula complicata with IKI negative asci, although Dennis describes it as a non-dark fungus with asci IKI blue. What do you think?

Björn Wergen, 12-06-2016

Hi there, today I was in Freibourg (Black Forest) for collecting some culms of Phyllostachys. At home, there appeared a pale coloured nectria-like species on one of the culms, of which I am sure it belongs to Protocreopsis. After looking for similar species, I have found an article about Protocreopsis caricicola growing on Carex from Mecklenburg, so this could be the second recolt in germany (?). Sp 13-14x3-3,4µm, with one central septation, smooth. Asci 50-60x5,5-7µm, 8sp, no apical apparatus seen in CB. Whole fruitbodies are covered with hyaline, thick-walled hairs and are embedded into a whitish cotton-like subiculum. Older fruitbodies get a yellow colour. Wall KOH-, CB-, 20-30µm thick constisting of 7-10 rows of parenchymatous cells and an up to 35µm thick layer of covering hyphae/hairs. 12-06-16, Freibourg, on old shoots of Phyllostachys sp. regards, björn

Lopadostoma on hardwood

Hi to all These pulvinate erumpent stromata grew on corticated wood of Quercus robur. The very polymorphic and aberrant ascospores are mostly in 4-spored asci. It could be the Lopadostoma dryophilum of the recent paper of Jaklitsch, Fournier. Rogers and Voglmayr? Thanks again

Pyreno on the sporophyte

HI again Blackish, not setose pseudothecia up to 0.2 mm in diameter are found subepidermial on the setae of the sporophytes of dead moss Ceratodon purpureus. The greenish smooth, dimorphic ascospores are < 20 microns long and the asci are bitunicate. I feel this a meber of the family Venturiaceae, maybe in the genus Lizonia or Venturia. Have you some idea? Thanks again

Aquatic asco

Hello again These gregarious, semi-inmersed, single or in small groups, blackish, glabrous, roundish, 0.3-0.5 mm in diam., pseudothecia with a inconspicuous papilla not laterally flattened, where growing on a broad Salix sp. branch near to the river at 1300 m (Somiedo-Asturias). The ascospores are hyaline and 1 septate, later greyish-brown, verrucose and secondarily septate, with no sheath or with only a thiny sheath when young. Asci clavate, bitunicate, 137-162 x 18-23, with 8 ascospores. Pseudoparaphyses cellular. It looks like Massarina 'griseospora' JF 06255 from Fournier's Keys, or it would be Massarina macrospora (Sacc.) O.E. Erikss. & J.Z. Yue. I'd like to know your opinion. Many thanks again

Spores slightly clavate, measuring 8.9 - 9.9 × 2.1 - 2.5 µm, OCI = 1. The asci measure 42.3 - 56.5 × 6.6 - 7.3 µm, with croziers, IKI+(bb). Paraphyses +- cylindrical, some a bit swollen. No hairs. I assume this is a Pyrenopeziza, and maybe someone knows the species?

Arachnocrea?

Hi to everybody: On a copious and cottony white subiculum situated on a rotten piece of hardwood I have collected these gergarious, superficially, easily separated, ostiolate, piriform, yellowish, orange or vinaceous small perithecia up to 300-350 microns. KOH negative. At this moment the ascomata are depauperate, collapsed and only part-spores I can see, but two days ago it had many cilindrical asci with 1-septate, apiculate ascospores, disarticulating in two conical part-spores. I think in the genus Arachnocrea and could be A. stipata. What do you think? Thanks! Enrique

Xylaria grex oxyacanthae

Hi to everybody and specially Jacques Fournier Today we have examined these gregarious stromata up to 40 mm high growing on buried seeds of Cornus sanguinea or Crataegus monogyna. We don't know what the host is because they are living together and the stromata were growing under both trees. After reading wonderfull Fournier's keys we are observing that our ascospores are greater: 12-16 x 5-7 versus 11-13 x 4.6-5.9 sec. Jacques. Also we have seen that collections on Cornus seeds can be greater. The question is: There is some innovation on this matter? Many thanks in advance

Pyreno on Corylus (Alnus?) bark

Hi to all: I wish to know your opinion about this fungus that grew on Corylus (Alnus?) bark. Ostiolate tubular necks erumpent across an stromatic and withish-ochrceous disc of 1 mm.

On bark

I need your help with this pyreno with small (o.2-0.3 mm)pyriform, caespitose, ostiolate, papillate, not setose, blackish, pseudothecia on a branch of harwood still attached to the tree. It has paraphysate ascomata KOH-negative, with bitunicate asci and the ascospores (hyaline or very pale pinkish), with no sheaths,have several transverse septa. Maybe a Pseudotrichia species? Many thanks in advance.

Fimicolous pyreno with hyaline dictyospores

Hi forum Has anyone some idea about these very small (up to 100 microns), scattered, brownish, globose, papilate, perithecia (marked with white arrow) growing on old horse dung covering by algae and small mosses? It is very curious the existence of few bitunicate 2-spored asci with white hyaline dictyospores. The material is well mature so I don't think it belongs to a a Pleosporales (i.e Pleophragmia or closely related genera) Many thanks for your help again

Small white ascomycete on Schoenoplectus

Hi to everybody These small white and subsessile ascomata 0.2-0.3 mm diameter grew gregariously on Schoenoplectus (Scirpus) stems. The IKI b (Calycina-type) asci have croziers. It has non-lanceolate filiform paraphyses, with a slightly enlarged obtuse apex containing some small refractive VBs (arrowed). The marginal hairs are very inconspicuous and they are made by two or three short cells with a short, subacute terminal element. I want to think in a Psilachnum species or even a Calycina (turgidella, ellisii...) but this collection doesn't seem to adapt well to anything I know. Do you have any ideas that could help me?

Ophiobolus or Similar with Short Spores

Hello Everyone, I have found fruit bodies of what I assume to be a species from the genus Ophiobolus. They were growing on a damp, dead, undetermined, thin herbaceous stem and on drying, the fruit bodies have collapsed noticably. The Shoemaker 1976 paper does not seem to contain a species matching the characteristics of mine. I notice some clear similarities between the shape and structure of the spores of my sample and those of the 16th May 2012 forum post by Enrique Rubio, (which was concluded to be an undescribed species). In mine though, the partly swollen cell is at the centre of the much shorter spores. I have attached an image of the fruit bodies and a sketch of the microscopy. I imagine that it will turn out to be another undescribed species, unless anyone can identify it. Thank you, With Best Wishes, Peter.

Asci up to50 x 8, 8-spored, IKI bb, arising from croziers. Paraphyses filiform. Ectal excipulum of an elongated textura prismatica. The apothecia grew on dead leaves of Saxifraga babiana subsp. septentrionalis, a cantabric endemism with viscid leaves growing on calcareous rocks at 1700 m of altitude (La Farrapona-Somiedo-Asturias). I feel the correct genus could be Urceolella and so it seems to be close to Urceolella saxifragae Svrcek that grows on Saxifraga aizoon with somewhat similar characters but longer ascospores and IKI negative asci (fide Raitviir). I attach Svrcek and Raitviir's description of U. saxifragae. Many thanks in advance

Helotiaceous fungus on male cones of Pinus radiata

Hi to all Last week-end we have collected these small, gregarious, pale witish or amber (when old), subturbinate or shortly stipitate up to 1mm high and 0.7 mm broad ascomata growing on male cones of Pinus radiata lying on the wet ground. It seems to have any blackened stromatized zones at their insertion on the host. The hymenium is never convex but it is plane to slightly concave. The ascospores are smooth, broadly fusiform and they seem to have 1 nucleus. Asci with croziers, 8-spored, with an apical apparatus weakly euamyloid, very difficult to observe and I don't know their type (Sclerotinia-type, Hymenoscyphus-type?) .. Living paraphyses with many rounded Vb's, hyaline to yellowish. Ectal excipulum is built by roundish to vesicular cells in a tetura globulosa-subangularis. No hairs in the apothecial margin; only cilyndrical to subclabvate elements with the same Vb's. I think perhaps this fungus belongs to the Sclerotiniaceae or Helotiaceae. I'm not sure...

Ectal excipulum angularis to prismatica with chains of 2-4 elements with incrustate and pigmentate walls that form the external furfuration. When we collect this fungus, we think in O. caeruleopruinosa, but the color of the hymenium and the spore size are very different. We don't know O. lilacina, but maybe our species is unknow. What do you think? Many thanks for your help

Calosphaeria on Carpinus betulus

Hi to all I need again your help with this fungus with subcuticular multi-perithecia growing together under the bark with their long necks converging, on an small branch of Carpinus betulus. Asci clavate 20-29 x 4-5, gradually tapering to a very slender, shortly stipitate, base. Paraphyses tapering, septate, much longer than the asci. I feel it is close to Calosphaeria microsperma Ellis & Everh. that grows on Carpinus too, but the ascospores in the diagnosis seem to be smaller and no so boomerang-shaped . Have you a better idea? Thanks again

Pyreno on a Sorbus branch

On dead branches of Sorbus aucuparia still attached to the tree. The fungus appears to form erumpent, blackish, stromata on which are placed some very small, more or less ovoid, blackish, glabrous pseudothecia, containing cylindrical, bitunicate asci with eight, greyish or yellowish-grey dictyospores, which react to give a bluish-grey colour in Melzer's reagent. The ascospore is not constricted at the septa. I rule out a Cucurbitaria, perhaps a Capronia with hairless pseudothecia? Teichospora? Any ideas would be welcome

White Calycina on indeterminate moncot

Hi again These gregarious, small (up to 0.5 mm high, 0.8 mm broad), shortly stipitate, elastic, fully withish ascomata, not reddening with the age were growing on old leaves of indeterminate monocots of I think grasses, not sedges but I'm not absolutely sure, at 1400 m of altitude on acid montane soil. Apothecial margins are only finely fimbriate. Ascospores hyaline, 1-septate, with may small lipid guttules that seem to form conidia. Asci IKI r (obviously b after KOH pret.), 8-spored, with no croziers or only small protuberances of abortive croziers. Excipulum built by a gelatinised tissue (textura oblita). I think in Calycina as the correct genus for it but I don't know a good species that matches with it. Calycina herbarum has not croziers too but their ascospores are longer. Can you help me?

Brunnipila on woody ericaceous host

Hi again The brownish hairs of these narrowly sessile apothecia are sepate, granulate, with crystal drusses at their tips, so I think it could belong to the genus Brunnipila. But I don't find a taxon that fits well with my collection, because the asci are IKI rb and don't have croziers at their bases. The paraphyses are broadly lanceolate and exceed the hymenium level. This fungus grew on subalpine environnement (1700 m) on a decorticated branch of an ericaceous plant, maybe Geista florida. Have you some ides for me? Thanks again

On Pseudotsuga

These sessile or subsessile apothecia, more or less turbinate, allways isolated, never in groups, 0.2-0.7 mm in diameter and blackish-brown in colour, erumpent through the bark of branches fallen to the ground in a plantation of Pseudotsuga menziesii at 1300 m of altitude in northern Spain . The apothecia have no ionomidotic reaction in KOH and the asci form very scanty primary ascosspores, difficult to see, but probably broadly ellipsoidal or subspherical, and finally the asci are filled with a multitude of small, subcylindrical to nearly allantoid, hyaline ascoconidia. From the appearance of the primary spore it could perhaps be Tympanis tsugae Groves, which may now belong to Claussenomyces or Vexillomyces. What do you think?

Enrique Rubio, 24-05-2013

Nemania maritima?

Hi to all I have found this fungus that makes erumpent, subinmersed, roundish, carbonaceous and blackish perithecia, isolated or in small groups of 3-4 covered by a whitish tomentum at the young age. They grow on the bark of a spiny tree or shrub that by the moment I don't know. The place is situated in the river mouth of the Nalón river in the Cantabric sea, with a obvious oceanic, saline, influence. The spores have a straight germ slit, difficult to observe, much less than spore lenght. I think in Nemania maritima What do you think? Thanks again

Hi to all My friend J. Linde, a great discover of minute fungi, collected these small, white, downy, shortly stipitate, briefly cupulate later pulvinate apothecia, 0.3-0.5 mm in diameter on seeds (samara) of Acer pseudoplatanus. Thea asci, 8-spored, are IKI negative and with croziers. The spores have only few minute guttules. Excipulum with textura + or - prismatica. The paraphyses are cylindrical, without conspicuous Vb's in water but stain in Crb. Close to the margin they become branched as the excipular hairs (marked with red arrows in the pic). The very dense excipular hairs have finger-like protuberances as the Mollisina species. I think it could be a Mollisina but I don't know a species that fits well with our fungus.

Pyreno on Cytisus

Hi again I'd like to know your opinion on this pyrenomycete growing on dead branches of Cytisus scoparius where it forms many small orbicular stromata up to 3 x 0.5 mm erumpent from bark.The asci are bitunicate, 8-spored and somewhat shortly stipitate. The ascospores have (2-)3 eusepta and a verrucose perisporium, no appendages, no sheats. Do you have some idea for help me? Many thanks again.

Discomycete on Typha

Bonsoir tous this is the first of two discomycetes I have just collected on Typha latifolia. Apothecia whitish, with a slight pink tinge - all micro-features appear hyaline. Excipulum globose/prismatic at base, the cells becoming narrower towards the margin. Asci 8-spored, IKI+, with croziers and most with a slightly pinched-out apex (see second micro photo). Paraphyses unbranched(?), parallel-sided, widening at apex and with c3 septa along their length; without any discernible contents. Ascospores elongate, with rounded apices and slightly tapering bases; many developing up to 3 septa while alive and in the ascus; (29.3)42.5-50.7 x 2.4-2.9µm. help/suggestions very welcome cordialement Chris

Strange roundish pyreno

Dear friends: Have you some idea about this strange roundish, densely gregarious, uniperitheciate pyrenomycete, up to 0.7-0.8 microns in diam, covered by a conspicuous white material? It was collected on the underside of a woody piece (perhaps Salix). The asci have a little refringent apparatus IKI and Melzer negative and the ascospores (2-guttulate in H2O) have any germ slit (or it is very inconspicuous). When I began to study it, my material was very damaged and for it I cannot do a good description but I see any dark peridial setae of Coniochaeta-type Many thanks again Enrique

Anthostomella on Fraxinus

Hello again I'd like to know your opinion about this (I think) Anthostomella species growing on small branches (20 mm broad) of Fraxinus excelsior lying on the ground, at the sea level (Botanical Garden of Gijón/Asturias/Spain). The inmersed, gregarious, blackish, roundish or elliptical perithecia, 1.20-1.35 microns in diam., are singly, in pairs or small groups just beneath the bark with only the short necks protruding. Many times an stromatized blackish clypeoid structure is present over the perithecia. Asci cylindrical, 145-155 x 7.5-8,5, unitunicate, with an apical cylindrical apparatus up to 3 microns long, deeply blueing in IKI, with 8 more or less uniseriate 2-celled ascospores that seem to have very small caps at the poles (that are not well visible in china ink). These ascospores, close to those of A. rubicola, are allways hyaline or only a few of them at most slightly brownish inside the asci. I don't know any species that fits with my fungus Have you any idea? Thanks again

Thelonectria? on corticated hardwood

HI again I need your help again with these isolated or caespitose perithecia up to 0.5 mm, situated on erumpent stromata, with mammate dark ostiole, KOH purple only in the upper region. Ascospores broadly fusiform, 1-septate, not constricted at the septum, smooth. Asci with truncate apex and a refringent conspicuous apical apparatus. Close to the perithecia we can observe fascicles of witish erect conidiophores that could be the conidial state of this fungus (cylindrocarpon?). Could be a Thelonectria species? Thanks again

Discomycete on Ribes

Hi, a curious discomycete collected on a Ribes branch. The asci are initially 8-spored but mostly 4-spored when mature. Ascospores are about 26-27 x 10-11 µm (only few free spores measured). The red apical apparatus in Lugol is very conspicuous. I saw that Enrique Rubio Domínguez has a similar collection named "Ostropalean, ERD-7792" in Zotto's Google Drive but with different ecology. I am looking forward to your ideas. Best wishes, Gernot

Pyreno on Alnus glutinosa

Hi to everybody I need your help with this fungus that forms superficial black, lageniform, ostiolate perithecia, up to 0.45 mm high, 0.2 mm broad with necks 0.1 mm in diameter, singly or clustered in groups of several perithecia covered by a copious whitish or greenish blue, aerugineous subiculum. Non stromatic or very inconspicually stromatic. The irregulary disposed clusters covering several cm on rotten wood of Alnus glutinosa at the Botanical garden of Gijón, at the north of Spain at the sea level. The narrowly clavate asci, 8-spored but four of them aborted, 44-58 x 4-5 microns, have an strongly refringent apical apparatus not really Melzer positive. The ascospores are hyaline, smooth, biguttulate, one-celled, 4.9-5.8 x 2.6-3.1. I don not have any good track, but perhaps you could help me? Thanks in advance

The globose to pyriform perithecium is covered by a clypeate structure with an epidermoid texture. Asci narrowly fusiform up to 175 x 4 with a n small refringent apical apparatus only well visible in IKI (IKI negative) or cotton blue.

Lophiostomataceous fungus

This pyrenomycete is very common on still attached branches of several trees and shrubs (Lonicera xylosteum, Rhamnus alaternus, Ligustrum, etc.) in the Botanical Garden of Gijón (Asturias, Spain). The globose pseudothecia 0.4-0.5 mm in diameter are just inmersed under the periderm and they have a conspicuous flattened papilla. Mature golden brown dictyospores have a thin mucous sheath thickened at the ventral side and long terminal appendages. Does anyone have any suggestions for this lophiostomataceous fungus? Many thanks in advance Enrique

Helotiale on Polytrichastrum formosum

These apothecia were growing on decaying leaves of Polytrichastrum formosusm. The apothecia are scattered, shortly stipitate. Disc brownish, briefly cupulate, later applanate or pulvinate, up to 1 mm in diameter. Excipulum minutely downy, whitish. Margin glabrous. Asci 62-100 x 10-14, 8-spored, without croziers, the apical pore IKI b of the Calycina-type. Paraphyses with no refractive VBs, covered by a crystalline (?) yellowish-brown matter that stains in Crb. Ectal excipulum with hyaline textura prismatica-angularis-subglobulosa. Medullary excipulum of textura intricata, the hyphae covered by the same yellowish-brown matter of the paraphyses. I feel this fungus is the same described by Spooner [Kew Bulletin 38(4):563-565 (1984)] under the name Bryoscyphus turbinatus (Fuckel) Spooner, but, in my opinion, the fungus is absolutely not a Bryoscyphus, because the lack of refractive VBs at the paraphyses and and the cellules of the ectal excipulum, and the apical pore of the Calycina-type. Furthermore the crystalline matter covering the paraphyses and the hyphae of the medullary excipulum is not present in the genus Bryoscyphus. What genus is appropiate for this fungus? I don't know, but in my opinion not Bryoscyphus. Probably the study of dry material did not allow a suitable study. What do you think?

Enrique Rubio, 04-09-2012

Diatrype on Betula

Can this fungus be Diatrype undulata? I have collected it on Betula alba branches at 1600 m and I think could be this species but the macro/micro-differences with another Diatrype species as D. decorticata are very small. Off course, I don't know the conidia. Ostioles are conical, split and slightly protruding. Perithecia up to 500 microns long. I see any blue reaction of the apical pore in Mlz., IKI or KOH pret. (Rappaz says that the asci are I (+)!!) What do you think? Many thanks again

Hi again These small (0.3-0.4 mm) narrowly sessile, whitish later amber-colour apothecia were growing on old stromata of pyrenomycetes on hardwood. The excipulum is mader by angular/subangular, roundish hyaline thin-walled cells, brownish near the base. And the marginal cells are smooth and narrowly clavate. Asci without croziers, IKI bb of the Calycina-type. Paraphyses filiform with no conspicuous content, no VBs. I think this fungus could be near to the genus Parorbiiopsis non s.str. How do you think?

Dear all I would like to know your opinion about these small, rounded, blackish, more or less spherical, very small (up to 0.15 mm in diameter), most probably ostiolate but without necks, immersed in overwintered leaves of Ulmus glabra. From its characters it could perhaps fits in the genus Gnomoniella and perhaps in Gnomoniella carpinea although its spores are somewhat wider than those of this species.What do you think? Many thanks again. Sorry, I just saw that Gnomoniella carpinea is a synonym of Apiosporopsis carpinea, a fungus that we usually collect on carpinus leaves near the site of the find.

Rosellinia on Salix wood

Hi to everybody and specially to J. Fournier, a very good specialist on this genus. Our common friend P. Zapico has found at his home these gregarious, blackish, roundish, papillate and ostiolate, carbonaceous, perithecia 0.9-1.4 mm in diam. growing over on more or less persistent subiculum on very rotten wood of a cut Salix babylonica. The asci are cylindrical, 8-spored, 155-170 x 8.5-9 microns, pars sporifera 110-138 with a conspicuous apical apparatus Melzer deep blue 5-6 x 4 micr. The ascospores are ellipsoid, equilateral, brownish at maturity, with straight germ slit nearly as long as spore, situated on the more convex side, and 1(-2) semiglobose cellular appendage (-s) surrounded by a partial, narrow slimy sheath. (14.7-)16.3(-18.2) x (6.5-)7.0(-8.0); Q = 2.1-2.5 I feel this fungus could be near to Rosellinia akulovii L.E. Petrini but I'd like to know your opinion. Many thanks in advance for your help

Hi to all: We have collected on hare dung these very small (up to 150 microns in diam.), cleistothecioid, roundish ascomata with a reddish brown excipulum. They have up to 7-8 big, clavate asci up to 80-100 x 30-32 microns that have >64 (maybe 128) ascospores. Mlz. (-), not operculate. We think could be Thelebolus dubius var. lagopi (Rea) Doveri. What do you think? Many thanks again Enrique

Bionectriaceae (?) on Ulmus

Hi to everybody. Hi Christian (by the way, what a wonderfull pics of Pleomassaria!) These small (up to 200-250 microns), gregarious, KOH-negative, superficial, not on a stroma, more or less glabrous perithecia, were found on Ulmus minor bark. They are not very well preserved, with no many ascospores for good measurements, but they seem to be smooth and with up to seven tranverse septa. Asci broadly fusiform. Peridium thick, up to 80 microns, complex, with an inner orange layer. No anamorph seen. What do you think?

Hyphodiscus on Cupressus leaves

Hi to everybody Few days ago I have collected several hundreds of these gregarious, white, cup-shaped, downy, shortly stipitate to subturbinate, minute (up to 0.4 mm in diameter) ascomata on very rotten leaves of Cupressus. The asci, up to 45 x 7 microns, have an apical pore IKI b (sometimes hardly visible) and they have croziers. The paraphyses and the excipular hairs have conspicuous Vb's that stain cresyl blue. The excipulum is slightly gelatinised. Hairs long cylindrical, hyaline, full lenght incrusted by a granulose matter or simply verrucose (?). All these characters seem to match with the genus Hyphodiscus, but I don't know some species that fits well with my collection. Some idea? Thanks again

On deer dung

Growing in deer dung at 1400 m altitude. I find it hard to believe that it could be Thelebolus microsporus because of the presence of brownish pigment in the excipulum and epithecium and the absence of yellow pigment. The brownish-purple ascomata of 175-225 microns were not aged at all. What do you think?

The beaked, scattered, glabrous, inmersed perithecia are up to 1 mm high with only the long necks erumpent across the surface. The asci are cylindrical, shortly stipitate, 63-85 x 6-7 microns, with an conspicuous apical apparatus IKI negative and 8 ascospores obliquely uniseriate. Paraphyses septate tapering at the end. Ascospores 8.5-11.5 x 4.3-4.9; Q = 1.96-2.58, allways 2-guttulate, smooth, maybe porate (?). I think this fungus agrees better with Xylomelasma than Ceratostomella. What do you think? Thanks again

Hi to all I need your help again with this fungus growing on wet wood of Erica arborea at 1400 m of altitude. The superficial, sessile, gregarious, roundish, rough, papillate, ostiolate,pseudothecia are 0.4-0.8 microns in diam. and they grew on a sparse subiculum of brownish hyphae. Their walls are carbonaceous and the inner wall of the young stromata have ochraceous or reddish pigments that don't exist around the ostiole as in B. schiedermayeriana. The 8-spored asc are bitunicate and shortly stipitate. Pseudoparaphyses trabeculate. Mature ascospores are brownish, 1 septate (or with 2 more secondary septa), no appendages, no sheath.

A propos de ma fiche sur Nimbomollisia melatephroides

Zotto Baral m'avertit, nouvellement, d'une erreur dans ma fiche de N. melatephroides. Effectivement, les asques dans l’IKI de la partie inférieure gauche, sont, en réalité de N. eriophori. Les deux champignons croissaient ensemble dans la même tige de Juncus. Je regrette de m’avoir trompé et pouvoir induire aux erreurs ou une critique le reste de collèges. Je vous demande des excuses par cela Zotto Baral informs me about a mistake in my card of N. melatephroides. Really, the asci in IKI of the low left part, are, indeed of N. eriophori. Both fungi was growing together in the same Juncus's stem I’m sorry to have mistaken and to induce to mistakes or critique to the rest of colleagues. I request my excuses for it

Plagiostoma on Euphorbia hyberna

Hi to all: Does anybody have this article? Orn another taxonomic information about this fungus. Kohn, L.M.; Nagasawa, E. (1984) A taxonomic reassessment of Sclerotinia camelliae Hara (=Ciborinia camelliae Kohn), with observations on flower blight of camellia in Japan.

Enrique Rubio, 30-04-2022

This Plagiostoma with perithecia immersed under the epidermis of stems of Euphorbia hyberna and with more or less central long necks (> 200 microns long) is common in the Cantabrian Mountains. The spores have a median septum and thin, barely perceptible appendages. I find no affinities with any of the euphorbiaceous species of the genus. Have any of you ever been able to study it? Thanks again.

Calycina guttulifera ?

Hi to everybody These very densely, gregarious apothecia were growing on the hymenium of a very decayed resupinate, poroid fungus on wood of Fagus sylvatica at 1000 m of altitude. The apothecia are white, shortly stipitate by a stout, broad, cylindrical pseudostipe. The white hymenium is briefly cupulate, later aplanate or only slightly convex, 200-500 microns in diameter. Excipulum downy, as the margin. The inconspicuous marginal cells are cylindrical or slightly clavate, smooth or finelly incrustate, but not verrucose as in Cistella species. Ectal excipulum of hyaline, roundish, angular to prismatical cells with no inclusions or VBs. Paraphyses optically empty, with no VBs. Asci 8-spored, IKI b or rb, with croziers. I think it could be near to Calycina guttulifera from Zotto's folder. What do you think? Thanks again

It forms blackish stromata with several deformed perithecia when compressed. The asci are long, polysporic, without a conspicuous apical apparatus and often strangulate, but the stipes do not appear to be long as in Coronophorales and the spores are small, allantoid and completely hyaline. Could be Fracchiaea a good genus for it? Many thanks in advance

Hamatocanthoscypha on Cupressus leaves

Hi again This material was sent to me from M. Tapia (Navarra, NE of Spain) as Hamatocanthoscypha species growing on rotten, blackish, leaves of Cupressus. The ascomata are minute, briefly stipitate and allways white. The spores are ovoid eguttulate or provided of 1-2 small polar guttules. Asi IKI negative (-), croziers positive (+). Paraphyses with any content. Ectal excipulum elongate of and + or - elongate textura prismatica. Hairs granulate, many of them uncinate. I think is a good Hamatocanthoscypha species that not fits well with H. obsoleta. In Zotto's CD there is an Hamatocanthoscypha 'rotundispora' HB- 7444 that is very close with this fungus. What's your opinion? Many thanks again Enrique

Seynesia (?) on Arundo donax

I'd like your opinion on this Seynesia (¿?) species growing on Arundo donax stems at the sea level, at the north of Spain. The blackish, roundish, inmersed perithecia, single or in pairs, are more or less roundish, up to 1 mm in diam., beneath a thin clypeus. Only the papilla is visible on the peridermis of the host, but it is not surrounded by teeth-like flanges as described for Seynesia nobilis. The 8-spored asci have a wedge-shaped, amyloid, subapical apparatus. The living paraphyses are filled with a conspicuous, refractive, oily content that not dissapear in NH4OH. The ascospores are brownish at maturity, smooth-walled, two celled, constricted at the septum, with a full length germ slit in each cell, a thin mucilaginous sheath surrounding the ascospores and an obtuse or short cylindrical, not really conical, cap-like appendage at each pole of the spore. I feel this species could be into the genus Seynesia, but I think it doesn't fit well with the somewhat known species of this genus (i.e. S. nobilis) What is your opnion Many thanks in advance

Fimicolous pyrenomycete from southern Spain

Hi to everybody I am surprised with these semi-inmersed perithecia growing in cow dung in southern Spain. There doesn't seem to be a well defined clypeus and the asci are neither amyloid nor dextrinoid, although they have an inconspicuous apical apparatus. The spores, surrounded by a wide gelatinous sheath after its expulsion from the asci, have no germ slits and they have a small caudal hyaline dwarf cell and an apical germinative pore. In theory the closest genus should be Hypocopra, but there are many evidences and contradictions against this genus. Do you have any idea that might help me?

White apothecia on Pseudotsuga

These small, white, gregarious, broadly sessile apothecia, 0.2-0.3 mm in diameter, with glabrous margins, grew among algae and liverworts on corticated wood of Pseudotsuga menziesii near the sea. The asci are ventricose, slightly dextrinoid in IKI, with croziers and a broad, very bluish apical apparatus in IKI, and contain eight spores already septate even inside the asci. The paraphyses are moniliform near the apex and the marginal hairs are similar and closely agglutinated. It doesn't look like a Hyaloscypha, but I couldn't say to which genus it might belong, perhaps it could be an ascolichen? Many thanks again

Asco on Cornus sanguinea leaves

Hi to everybody Some time ago my friend M. Tapia, from Navarra (NE of Spain) sent me this strange, gregarious, turbinate, 0.2-0.5 mm in diam., pale grayish-brownish with brownish pruinose hymenium surface by the existence of a brownish, verruculose, granulate, matter that not dissolves in KOH, growing on old leaves of Cornus sanguinea. The apothecia seems to be glabrous, and many leaves have hyaline or translucent gelatinous conidiomata perhaps belonging to his asexual morph. The asci are IKI negative, with no croziers and the ascospores do not turn darker. I could see that some paraphyses have VBs that stain in cresyl blue.

Hi to all This fungus grew on a culture of fox dung with many rests of animal hairs, and forms small, gregarious, superficial, roundish, yellowish at first, later orange and finally brownish cleistothecioid, smooth, ascomata, growing under a very copious white hypal mat. The asci are small, roundish to ovoid, and the ascospores are smooth, yellowish, roundish or very broadly ellipsoid, 4.5-5.2 x 3.8-5.2 microns. Cleistothecial walls built by a yellowish textura angularis. I feel this fungus belongs to Onygenales and it could be near to Aphanoascus fulvescens, a keratinophilic fungus, but J.

Arachnocrea on Agaricales

Hi again This Arachnocrea species grew on the hymenium of Agaricales, maybe Rhodocollybia prolixa var. distorta, over a dense, white subiculum. The perithecia are small, up to 0.4 mm in diam., slightly papillate, pale yellow and KOH negative. The part-spores are more or less monomorphic, conical, maybe smooth but no apiculate as in a previous own record on Fagus wood. Do you think this fungus could be A. stipata, that I think has apiculate ascospores and not recorded on Agaricales?

Didymosphaeria (?) on Vitis

Hi to all I'd like to know your opinion about this fungus that makes globose or pyriform inmersed pseudothecia (I think the asci are not unitunicate) < 500 microns on a Vitis vinifera branch. Their protruding necks are somewhat stout and they are up to 200 microns long. Hamathecial filaments hyaline, much branched and with anastomosis. Ascospores with conspicuous striate walls. Pseudothecial walls pseudoprosenchimatous. My guest is Didymosphaeria massarioides. What do you think? Thans again

Melanospora on incubated rabitt dung

Hi to everybody These small (0.3-0.4 mm) orange perithecia grew on incubated rabitt dung for one month. They seem to be ostiolate because there is a crown of hyaline setae around the very inconspicuous, not protruding, neck. Perithecial walls are more o less glabrous. Asci clavate. Ascospores citriform, biporate with smooth walls. According to GARCIA & al. (STUDIES IN MYCOLOGY 50: 63–68. 2004) the genus Sphaerodes currently comprise species characterized by non-ostiolate ascomata (if they are ostiolate they have a short neck surrounded by a crown of hyaline setae) and reticulate ascospores, umbonate at both ends. So only rest Melanospora as a good choice for my fungus. But I don't know a keyed species that matches with this collection. Could you help me? Thanks in advance

Ascospores of my fungus are broader than M. lineolata (14-24 x 3-5) or M. psammae (10-12 x 2.5-3 sec. DENNIS, 1983) another common graminicolous fungi on Ammophila .

Eutypella on Juglans

Hi to all We have found these pustulate, ellipsoid, scattered, erumpent stromata up to 18 mm in diam. and 1 mm high on small branches of Juglans nigra lying on the ground. Perithecial necks are black protruding, long cylindrical and furrowed, and the entostroma is pale ochraceous or withish. Ascospores are allantoid, subhyaline, not or only very pale yellowish, 8.2-10.3 x 1.9-2.4. Asci shortly stipitate with a pars sporifera 25-33, with a conspicuous apical apparatus deeply blue in IKI. Some ascospores (aberrant?) are ellipsoid, not allantoid (marked with white arrow). I think this fungus could be EUTYPELLA JUGLANDICOLA (Schwein.: Fr.) Ellis & Everh, at least sensu Rappaz (Mycologia Helvetica, 1987), but surprisingly the Index Fungorum says that this fungus is only a synonym of Botryosphaeroia obtusa.

Amphisphaeriales

These blackish, effuse stromata have immersed perithecia up to 0.5 mm in diameter, visible as obtuse swellings on the wood, perhaps of Acer. The long asci have a discoid and amyloid apical apparatus and the spores, with smooth walls, are light-coloured for a long time and then gradually become olivaceous and finally dark brown, without gelatinous sheaths or germ slits. I suppose it could belong to the genus Amphisphaeria, but I can't find any species well adapted to these characters. Perhaps someone might have some idea that could help me. Many thanks in advance.

Xylariaceous fungus on Genista florida

Hi to everybody This fungus was collected on small cutted branches, up to 10 mm broad, of Genista florida not lying on the ground, at the Natural Park of Somiedo (N of Spain), at 1500 m of altitude. It grew together with stromata of Thyronectria roseovirens. The fruitbodys are made of several subcuticular, blackish, perithecia more or less circinate, not forming a not well definite ascostroma, in valsoid configuration, with erumpent blackish ostioles. The cylindrical, shortly stipitate 8-spored asci have a conspicuous apical apparatus NOT STAINING BLUE in IKI and the ellipsoid, brownish, unicellular ascospores have a full lenght germ slit. Paraphyses are present. I think this fungus belongs to Xyalariaceae and maybe it could be into the genus Lopadostoma but the inamyloid asci don't fit well with this genus.

Calycellina?

Hello my friends I present you a new problem with these small (up to 1 mm), white, stipitate, gelatinous, 'cyathiculoid' ascomata that grows on Fagus (Betula?) wood close to the river at 1500 m. The long, fusiform, not septate, multiguttulate ascospores are very peculiar at least for me. The asci have an apical broad pore that I think is of Calycellina-type (?), reddish at low concentrations of IKI and very blue at higher. They seems to have not croziers and they are 8-spored. Paraphyses and marginal cells have conspicuous Vb's as the subhymenium too. Excipulum of textura porrecta. I think could be a Calycellina species but I'd like to know your opinion. Many thanks again Enrique

Low septate Ophiobolus on herbaceous stems

This Ophiobolus (¿) species is extremely common on herbaceous stems (ie. Ranunculus) in Somiedo in the montaneous zones(1000-1400 m) of the Park. The pseudothecia (375-450 µm) are inmersed with only the thick papilla raising the periderm of the host. The pale golden-brown ascospores are mainly 5-septate, rarely 6-septate, with a enlarged zone at the top of the third cell. Long time ago I have asked you for this fungus. Maybe you have some new ideas for me? Thanks again

Harmaja: Tarzetta spurcata

Hi, I have a collection of a Tarzetta species here from today's field trip which seems to be Tarzetta spurcata as described e.g. by Häffner (1992) or Boudier 337 (as Pustularia ochracea). Unfortunately I don't have Harmaja's paper so I wanted to ask if anybody could send me Harmaja, H. 1974. Tarzetta pusilla n. sp. and T. spurcata (Pers.) n. comb. from Finland. Karstenia. 14:116-120 Thanks and best wishes, Gernot

Didymosphaeriaceae (?) on Ulmus branch

Hi again I have found on fallen branches broken by the wind, these small (500-870 microns high, up to 100 microns broad), pyriform, subepidermial or inmersed on the wood, somewhat glabrous pseudothecia, solitary or arranged in fused groups, on Ulmus minor. The fungus seems to be xerophilous, because only the fall of the branches allowed me to see it. The asci I think are not unitunicate, although that is not easy for me, with a variable numeber of ascospores (often 8). Pseudoparaphyses narrowly trabeculate. Ascospores yellowish, brownish, brownish-black, uniseptate (secondarily septate at maturity), heteromorphic, with clearly longitudinaly striate walls, sometimes sub-reticulate. Pseudothecial inner walls with hyaline prismatic or roundish cells. I think could be near to Didymosphaeria, because the pseudothecia are not arranged in Valsoid-type as in the Valsariales. Have you some idea for me? Many thanks again

Pseudomassaria?

Hi to all: We have collected these small perithecia (or pseudothecia?) up to 0.5 mm in diam. inmersed under the bark of branches of indeterminate hardwood (Acer or Prunus, not Tilia). Ostioles are very nconspicuous. The spores are very unequally 2-celled. Asci seem to have a very inconspicuous apical apparatus but I'm not sure. They are Melzer negative. I think in the genus Pseudomassaria but their asci are described as Melzer positive... What do you think? Many thanks again

Mollisia on Fagus

These small, gregarious apothecia up to 0.5 mm in diameter grew on a branch of Fagus sylvatica fallen to the ground at 1300 m altitude. At the beginning they are whitish, but step by step they are invading of gray or amber gray color from the base. The asci have croziers and the apical pore is IKI b . The margin is not overflowing and it is made by hyaline clavate cells with vacuolar bodys. The paraphyses contain vacuoles sometimes abundant, sometimes refractive, sometimes not, so the content is not clearly that of a Mollisia. KOH negative or almost negative. I think it's a Mollisia, perhaps related to the amberina/ subamberina/sublivbidula group, but the asci IKI b seem to separate it from this complex. What do you think?

Pyrenopeziza (?) on Acacia melanoxylon

Hi again These ascomata grew on corticated wood of Acacia melanoxylon lying on the ground in the NW of Spain. The colour of the hymenium varies from whitish to greyish and becomes amber in drier specimens. The excipulum is brown or orange-brown (pigmented textura angularis o globulosa-angularis) and the margins are not overflowing. Ascomata KOH negative. Asci are IKI negative with croziers and form spores with high lipid content which only septate at maturity and always outside the asci. The paraphyses are filiform, barely dilated at the apex lacking refringent content, so I think Pyrenopeziza is the appropriate genus for this collection, a genus with very few lignicolous species, none of which are coincident. Do you have any idea that could help me? Many thanks again

Nemania on Salix

Dear friends: I need your help for to know this Nemania species that grew on the underside of a piece of wood of Salix alba in a very wet place periodically covered by the water of a lake. The blackish multiperitheciate stromata are crust of 50 x 25 mm and 1 mm thick covered by a mass of olivaceous fresh discharged ascospores. Ostioles conspicually papillate. The perithecia are ellipsoid and 0.45-0.70 mm long. The tissue beneath the perithecial layer is whitish, soft,extending into the wood. The asci are long stipitate, 180-207 x 8 microns, pars sporifera 98-107. The apical apparatus is IKI and Mlz. deep blue. Fresh ascospores, 12-17 x 5-6, are brownish olivaceous and they have a short, inconpicuous germ slit probably situated on the more convex side. I think this fungus is close to Nemania aenea var. macrospora or the Nemania sp. leg. J. Vivant from the wonderfull Fournier's web page. Have you any idea? Thanks again

The ascomata are shortly stipitate by a short and stout pseudostipe and they are up to 2 mm in diam. The hymenium seems to be reddening with the age. The spores are very polimorphic and up to 1-(2-3) septate at maturity. At the moment of the study they have septa inside the living asci. Asci IKI b of the Hymenoscyphus-type, Without croziers. Only repetitive false croziers or abortive croziers at their base. Paraphyses with multiguttulate Vb's. Ectal excipulum made of a brownish textura globuloso-angularis or only angularis. Medullary excipulum textura intricata. I feel my fungus is close to Hymenoscyphus. What's your opinion? Many thanks again

On Quercus ilex cupules

Hi again My friend M. Tapia of Navarra (NE of Spain) ask to me for these substipitate by a short and stout stipe gregarious ascomata that grew on Quercus ilex old cupules. The asci are IKI negative, croziers positive and the paraphyses have some little refractive Vb's. The spores are very polimorphic, ultimately 1-septate and the ectal excipulum have a textura + or - angularis. Have you some idea? Maybe a Pachydisca species? Thanks again

Ayuda con una coprófila

Hola. Unos diminutos peritecios globosos de color negro de entre 0,19 a 0,23 mm. que brotaban sobre excrementos de ganado vacuno, compartiendo espacio con unos ejemplares de Cheilymenia stercorea. Dos tipos de esporas distintos, por un lado unas formaciones que podrían corresponder a conidios, fuertemente pigmentadas de marrón con la base truncada donde están adheridas a un pedicelo hialino. Estos posibles conidios con unas medidas de (18) 18.9 - 20.9 (21.9) × (8.5) 8.8 - 9.8 (10.2) µm. Ascos sin reacción al Melzer. Ascosporas cilíndricas y sinuosas con dos largos cilios, uno en cada extremo de la espora y con múltiples vacuolas lipidas globosas en su interior, con unas medidas sin contar los cilios de (46) 47.2 - 55.3 (55.9) × (4.7) 4.9 - 5.7 (7.3) µm. Esto creo haberlo visto antes por aquí pero no recuerdo a que puede corresponder. Cualquier opinión será bien recibida. Muchas gracias de antemano. Saludos cordiales.

Hyaloscypha/Psilocistella on hardwood

Hi again I'd like to call it Hyaloscypha quercina Velen.[= Psilocistella quercina (Velen.) Svrcek] but I think it is not possible because the anguste cylindricae spores 5-8 in the original description of this taxon. Hyaloscypha quercicola (Velen.) Huhtinen with asci not arising from croziers, shorter hairs and ascospores 7-12.5 x 2-3 microns, neither fits well with my fungus, but yes, it looks alike Baral's folder Psilocistella quercina. The scattered apothecia of my collection are somewhat sessile, up to 0.6 mm, whitish but reddening after damage or with the age, but not with NH4OH. Asci IKI b Calycina-type, 8-spored, arising from croziers. Excipulum of textura prismatica. The long hyaline obtuse hairs, up to 125 x 4, are undulate, up to 4-septate, arising from slightly broadened base. They don't have any apical solidification (as in Protounguicularia variepilosa). No subiculum I have seen. Could you help me again? Thanks a lot

Cistella on dead parts of Arenaria grandiflora

Hi to all These minute (up to 0.35 mm) urceolate apothecia were growing on the underside, on dead parts of Arenaria grandiflora L. subsp. incrassata, a postrate small plant living on calcareous rocks. This collection was made at Saliencia, Somiedo, at 1400 m of altitude. The 8-spored asci, 39-58 x 5-8, arising from croziers, IKI b. Ascospores cylindric or cylindric-clavate, (9-)12(-17) x 1.5-2.7, with some polar small guttules. Hairs apex 2-5 microns broad, with a spiny ornamentation. The prismatic cells of the ectal excipulum with granules of ochraceous pigment. Maybe this fungus is close to the more caulicolous 'Cistella grevillei complex', with shorter, different ascospores and larger apothecia, but I'd like to know your opinion Many thanks in advance

Hyalopeziza on Rhamnus

Hi again These tiny apothecia (100-200 µm) were growing on wood of still attached branches of Rhamnus alpina at 1700 m altitude. I had not studied them until I was able to detect them with the bino three weeks after I had collected them. Erumpent from the wood, with an olive-grey hymenium, asci without croziers, IKI-negative and spores without septa with a relatively high lipid content. The excipular hairs do not have solidifications nor septa, nor dextrinoid, but they do have walls up to 1 µm with a continuous lumen. Despite their conditions, the apos appear to have tolerated desiccation perfectly well. The material agrees fairly well, except in some respects, with Raschle's description of Hyalopeziza nectrioidea, but less well with those of some other authors.What do you think? Many thanks in advance

Diaporthale on Juglans regia

Dear friends of the forum I need your help with this fungus that forms inmersed perithecia flask-shaped up to 250 microns. These perithecia, solitary, in pairs or in 'valsoid' groups have short or long necks with ostioles scarcely protruding and very inconspicuous. I have seen any obvious stroma or stromatic disk. No black line. I had seen these perithecia only when I cut the branch, because I was not suspecting that they are here. The perithecia are placed just below the periderm with short necks or at some mm and then its necks are longer. The branches of Juglans regia are 20 mm in diam. and they are liying on the ground. I don't know a good genus for my fungus. Maybe Cryptodiaporthe? Many thanks again for your help. Enrique

Xylariaceous fungus on Acacia melanoxylon

Hi to everyone This superficial, globose, finely craked, blackish-brown stromata, 10 mm high 15 mm broad is narrowly attached on bark of Acacia melanoxylon together with stromata of Daldinia sp., Jumillera cinerea and Nemania aureolutea. The small monostichous perithecia are more or less globose, 0.6-0.8 x 0.5-0.7 mm, with a roundish conspicuous papilla KOH-extractable pigments brightly greenish. Asci long stipitate 225-262 x 9-10, pars sporifera 142-160, 8-sspored, with a conspicuous hat shaped apical apparatus deeply blue in Mlz. and IKI, longer than broad. Ascospores olive brownish, 21-27 x 7-8.5, with a germ-slit shorter spore lenght on the less convex side. Perispore indehiscent in KOH. Could be a penzigioid Xylaria species? Are normal the existence of KOH-extractable pigments for these fungi? Thanks again

Another fungus on Tilia wood

Hello again and happy new year for all Together with the ascomata of Psilocistella/Psilachnum species on Tilia wood that turns reddish with ammonia vapour (see the macrophoto) they were another witish cupulate ascomata with big 8-spored asci IKI (-) negative and croziers (+) positive. IKI with KOH pret. is negative (-) too. The marginal hairs are very agglutinated and very difficult to segregate. Initially they seem to be smooth but the end cell is very finelly verrucose in KOH.

Je lance donc un appel à ceux d'entre vous qui auront la chance de le récolter en bon état (avec asques et spores), je leur demande de me faire parvenir leur récolte après séchage lent à température ambiante. Le printemps n'est certainement pas la meilleure période pour le trouver, mais je peux attendre jusqu'à l'automne. D'avance un grand merci pour votre aide! Amitiés, Jacques

Unguiculariopsis on Gibberella stromata

Hi again I'd like to know your opinion about this Unguiculariospsis species that grew on very old stromata of Gibberella baccata f. sp. moricola on still attached branches of Morus nigra. The perfectly roundish ascospores, relatively long 8-spored asci IKI negative (-), with croziers and the paraphyses longer than the asci say me that this fungus is close to Unguiculariosis ravenellii subsp. hamata but I have seen any Rhytidhysteron under the ascomata. Have you any idea for help me? Thanks again

Phaeohelotium??

Hello everyone, on 04/09/21 I found the following asco growing on chestnut husks and surrounding litter in the Galgenbossen in Elverdinge, Belgium. I suspect a Phaeohelotium sp.. Traces: Av 15.31x4.38µm (N=17); some tracks septated. Asci: J-; with croziers Paraphyses: multiseptated; sometimes forked, with (sparing) oil drops. Possible to adjust this determination? Regards, William

Another strange Mollisia on Sarothamnus scoparius (Cytisus s.)

Hi to all These blackish, sessile and minute ascomata grew on the wood of lying branches of Sarothamnus scoparius at 1500 m of altitude. The asci are IKI negative (KOH pret. = negative too), croziers + and they have 8 ascospores 3-septate inside the living asci. Ascomata KOH negative. Marginal 'hairs' blackish brown 2-3 celled Medullary excipulum is subhyaline. Ectal excipulum blackish brown or olivaceous black. The provisional Baral's name of 'Mollisia cytisi' has asci IKI bb I don't know this species. Can you help me again? Many thanks Enrique

apothecia of ascolichen or lichenicolous fungus?

Minute orange apothecia firmly anchored to the lichen thallus, that a friend of mine tells me can be a Nephroma. These apothecia are relatively hard, the asci react very deeply in IKI giving a very intense blue color, almost greenish and the excípulum seems to contain greenish cells perhaps coming from the algae. The asci appear be bitunicated and contain eight broadly fusiform spores, with yellowish walls. By the other hand. the apothecia have some hyaline septate thick-walled hairs which seems to me a rare character in this type of fungus. In other words: I don't know if it's just simply the ascomata of the lichen or if it's a lichenicolous parasitic fungus. I'd like to know your opinion Thanks again

Godronia urceolus? - on Betula from Norway

on 4.7.22, in the marginal area of National Park Skjaekerfjella, on a thin twig of Betula nana in marshy fjell-vegetation. The few apothecia first were fully unripe, and I took the with me in a moist plastic bag for weeks and still kept it at home before it became halfway ripe. Unfortunately, I missed to take spore measures, but fortunately have a measure in my pictures to estimate. There is no material left now. I think this could be Godronia urceolus. Can somebody confirm this or express another opinion? Yours, Lothar

Pyrenomycete on wet hardwood

Hello friends of the forum. I would like to know your opinion about these scattered perithecia growing on semirotten and very wet wood of Populus, who were neither half-submerged in water nor near a river. The (sub) superficial blackish ostiolate peritecia up to 300 microns in diameter, more or less carbonaceous, pyriform, papilate but no beaked, glabrous. Asci long cylindrical, 8-spored, with a long attenuated base, 165-200 x 10-11, with a thick refractive, Melzer negative, apical annulus. Paraphyses filiform. Ascospores hyaline, mostly with 5 eusepta. No anamorph I have seen. In a way it seems to remind me of a species of the genus Chaetosphaeria (Ch. cupulifera), but the ring of the asci seems excessively large, as does its length. Do you have some idea for this collection? Thanks again

Bluish Otidea

This Otidea grew at 1000 m in a forest with Corylus avellana and Fagus sylvatica on calcareous soil. The pruinose young excipulum has persistent lilaceous hues. Excipulum not reddish in Melzer's reactive, bright yellow in KOH (fresh material). Neither crystal-like aggregates among the hyphae of the medullary excipulum, nor striate exudates on these cells. This species is relatively common in Asturias (north of Spain) on calcareous soils of forest without conifers. I think that the strongly yellow reaction in KOH of the fresh ectal excipulum, and the rest of the characters I have described separate it from O. caeruleopruinosa, O. bufonia and Otidea mirabilis. What do you think?

Melanopsammella

Hello everyone, Collected on a decorticated branch of Quercus robur here in Belgium: Ascomata superficial to slightly immersed, subglobose, 0,1-0,15 mm diam., papillate, pale brown, covered by black setae. Asci cylindrical, apex truncate, 8-spored but mostly observed with 16 part-spores, 42-47x6 µm. Spores fusiform, constricted 1-septate, soon disarticulating in part-spores; part-spores ellipsoid to wedge-shaped, smooth, hyaline, 3-3,5x1,5-2 µm. Paraphyses soon disappearing. Ectal excipulum of pale brown, small-celled textura ?epidermoidea; setae acute, base swollen, smooth, thin-walled, aseptate, blackish, 39-56x7-10 µm.  With those Hypocrea-like spores, this must be a Melanopsammella? Unfortunately, I only have documentation of species with septate hairs. Your help is welcome. Bernard

Unknown Helotiales on Juniperus sabinae

Salut a tous, yesterday i found this little discomycete on leaves of Juniperus sabinae: Apothezia: 0,3-0,8mm, fresh translucent to white, drying the hymenium becomes greyish to light brown, stalked up to to 0,5 mm, base is blackening (!). Asci 40-50 x 6-8, J+ (blue), Croziers +. Spores 8-9 x 4, Oil 0-1. Excipulum ends in little hairs up to 8-12, 1-septated, a little curved and apical swollen. they seem to be very fine warted, not totally smooth. It reminds me at genus Cistella, but I'm not really convinced by this idea. Is there a species on Juniperus? Who can help? All best from Dirk

Helminthosphaeriaceae on Ficus carica

Hi my friends I'd like to know your opinion on this peculiar fungus. Perithecia superficial, gregarious, growing on branches of Ficus carica still attached to the tree but close to the ground, but away from water, apparently not growing on pyrenomycetes or other fungi. Pyriform, 200-400 µm high, collapsing vertically when dry, blackish, ostiolate, densely hirsute due to subhyaline or light brown hairs with acute apex, multiseptate, (100-)165(-225) x (10-)11(-12) µm with thick walls 1.5-3.0 µm. Asci fusoid (72-)80(-102) x (14-)17(-20) µm, 8-spored, without an apical apparatus or subapical globule visible. Ascospores ellipsoidal (18.0-)20.0(-22.5) x (7.0-)7.5(-8.0) µm; Q = (2.3-)2.7(-3.0), with obtuse poles only slightly attenuate; hyaline, yellowish at maturity, constricted to a median transverse septum, ornamented by conspicuous warts up to 1 µm high surrounded by a thick, usually persistent episporium. The fungos shares characters of Echinosphaeria and Helminthosphaeria. It seems close to Echinosphaeria incondita A.E. Bell & Mahoney, CBS Biodiversity Series 15: 79 (2016) with aquatic ecology, with up to 3 septa more fusiform larger ascospores 25-31 x 6-8, not constricted and asci vith an apical apparatus.

Pyreno with long neck + IKI blue

Found on hardwood, plenty of these long necks arising from the bark. Difficult to have a good photo of the ascus, there are probably very thin. The apical pore is slightly blue in IKI. Spores small, variable in shape and size, 3,5 - 6 x 1 - 1,8 µm, often slightly bent, sometimes strongly, pale yellow brown under the microscope. Looks like Togninia minima, but the ascus blue in IKI does not fit. Thanks and best regards, Daniel

Pyreno with greenish ascospores on Alnus glutinosa

Hi to all On medium size (40-70 mm in diam.) felled branches of Alnus glutinosa lying on the ground I have found many inmersed, at first hyaline later greenish, perithecia that no are into a clearly definited stroma. No ventral black lines. The necks are protruding across a well visible greyish disc. The asci have an apical refringent apparatus and they are abruptly contracted at their base (Diaporthales). No paraphyses I have seen. The ascospores are hyaline, later greenish, 1-(0) septate, very polimorphic, with some aberrant forms. No appendages. The spores are surrounded by a gelatinous sheath. Dispersed between the perithecia they are many inmersed greenish conidiomata that could be the anamorphic state of this fungus. What do you think? Thanks again

Helotiale on Ligustrum leaves

These apothecioid ascomata are gregarious, superficial but perhaps erumpent, and colonise the underside of overwintered Ligustrum ovalifolium leaves. They are very exiguous and measure 100-200 microns in diameter; sessile, initially very shortly cupulate, later flattened to become convex and pulvinate and possess abundant and conspicuous excipular hairs with several septa, the base of which arises from a pigmented vesicular cell and the ends with an hyaline and obtuse apex. Their walls are not smooth but slightly roughened, as if encrusted, but not truly warty like those of the genus Cistella. The excípulum has an angularis or prismatica texture with angular or more or less rectangular cells, with the walls provided with a yellowish-brown pigment. The 8-spored asci are clavate, with a base without croziers and a probable apical pore with no reaction in IKI. The ascospores are hyaline and smooth, cylindrical, with a fine guttular content. I envisage two genera for this ascomycete: Cistella and Psilachnum, although I am more inclined to the latter as the hairs do not have distinctly warty walls. What do yo think?

Mollisia pteridis

Following the thread of Lieve Deceuninck's message in this same forum http://www.ascofrance.com/search_forum/48820 about Mollisia pteridis Gillet, I have found several cupulate and sessile ascomata up to 0.5 mm in diameter, KOH negative, on blackened parts of Pteridium aquilinum rachis. The exccipulum is hairy and formed by a brownish textura angularis which on the flanks of the fruitbodys forms septate, long and pigmented hairs, while on the margin these are also long but hyaline. The paraphyses have small vacuoles that stain in cresyl blue, but do not contain the large cylindrical and refractive VBs typical of the genus Mollisia. This fungus that Ellis & Ellis assimilate to Mollisia pteridis and that fits very well with the drawings they make of the lateral and marginal hairs, could also fits with Gillet's succinct description. What do you think?

Strange fungus on Phragmites stems

Hi forum. These tiny, gregarious, gregarious, blackish, conical or pyriform ascomata up to 200 µm long, grew on Phragmites australis stems. The ascomata are glabrous, but the necks of the ascomata are fimbriated by long hyaline hairs but more shorter brownish hairs surround the ostiole. I see no paraphyses and the asci are very peculiar, cylindrical, rather long, sometimes more than 100 µm long, without reaction in Melzer's reagent, with numerous small, ellipsoidal, hyaline ascospores. I don't know their discharge mechanism and am therefore I'm very confused about the placement of this fungus, which I don't exclude that it could be lichenized since numerous green algae surround the ascomata. Do you have any idea that could help me?

Pyrenopeziza digitalina? Je ne suis pas sûr

Bonjour, Cet disco était sur un Digitalis purpurea mort. C'est Pyrenopeziza digitalina? Je ne le pense pas. Mais qu'est-ce que c'est? We found this little disco on the flower stalks and dead flower remains of Foxglve, Digitalis purpurea. It was with Flagelloscypha (cyphelloid), and the Hymenomycetes Periconia byssoides and Dendryphion comosum. The only similar species of discomycete on Digitalis in the UK seems to be Pyrenopeziza digitalina. However, that species isn't described as having hairs, is reported to be found on dead stems, and looks darker. Pezizella discreta and Pyrenopeziza revincta have also been found on Digitalis, but I don't think I have one of those. The ascocarps were sessile, fringed, and up to 0.3 mm diameter. Released spores were few but I estimated them to be about 7-10 x 1.5-2. Asci were biseriate, without croziers, and typically 40 x 5. The tips turned blue in Lugol. Some cells looked like hairs, and were minutely spiny. Cordialement, Steve

Hi again This fungs has superficial, gregrious, pyriform, with a small papilla, ostiolate, yellowish perithecia up to 300 microns and grews on very wet rotten hardwood (Fagus, Betula) at 1500 m close to the river. KOH negative (or only more vivid yellow). The perithecia show conspicuous appendages. The spores are 1-septate, maybe smooth. Asci fusiform with an apical apparatus refringent in Melzer and clearly visible in cotton blue. Have you any idea? Thanks again

Ayuda a determinar

Hola, buenos días a todos. Subo unas fotos de un asco que encontramos ayer sobre tierra y algún resto de hojas en una chopera recién talada. Esporas con gútulas en su interior, que miden 16,5-19 x 10-11 micras. Ascas no amiloides, pleurorrincas. Vistos pelos ¿hifoides? en base de apotecio. En el campo, pensé en Cheilymenia granulata pero creo que no encaja. ¿Podrían ayudarme? Gracias por sus respuestas. Rubén

Asco on stromata of Rhytisma salicinum

Hello again This spring we have found this strange fungus, perhaps close to the genus Ciboria, growing on old stromata of Rhytisma salicinum on decaying leaves lying on the ground of Salix sp. at 1600 m of altitude. At the same place thay are many stromata with the ascomata of Rhytisma salicinum hanging on the branches of Salix. This fungus was previously collected in another far place by our friend A. Román and was showed in Ascofrance <a href="../search_forum/7900">http://www.ascofrance.com/search_forum/7900</a>. The ascospores are 2-nucleate, with polar dextrinoid bodys and late they seem to make sphaeric microconidia. Asci with apical pore of the Sclerotinia-type, with croziers. Medullary excipulum of textura intricata. Ectal excipulum globulosa, not blueing in IKI. The paraphyses have not conspicuous Vb's. Have you any idea? Thanks again

Laetinaevia (?) on grasses

Hi to all I need your help with these pinkish orange erumpent ascomata up to 0.5 mm by a longitudinal rupture of the peridermis of the host. There are not lips or valves around them. The lateral ectal excipulum seems to be a prismatical/subangularis texture but it is very difficult to cut well. Asci with croziers, 8-spored, IKI red or dirty red blue in IKI (at high concentration), IKI b after KOH pret. The end cells of the paraphyses have a peculiar snake head-like morfology and they have big roundish but incolore Vb's. I think it belongs to the genus Laetinaevia but I don't see it in Hein's paper on this genus. The fungus wwas found growing on indeterminate grasses at 1500 m of altitude Have you any idea?

Cyathicula on Urtica stems

Hi again This Cyathicula species was growing on old stems of Urtica dioica at 900 m of altitude. The ascomata are stipitate and fully whitish, with a fimbriate margin made by cylindric-clavate cells with many small refractive guttules as in the paraphyses. The ascospores have some small LBs at their poles and no septa. Asci IKI b, 52-68 x 5-7, without croziers. Ectal excipulum textura oblita covered by many crystals. I think this collection deviates from typical Cyathicula cyathoidea, said to have croziers, so I'd like to know your opinion. Many thanks again

White Calycina on hardwood

Hi to all: We have found this Calycina species on very wet eroded hardwood very close to the water level. Apothecia, up to 1 mm in diam., are fully white, not reddening, stipitate and they have a convex hymenium. No Chalara anamorph I have seen. I think it's closely related (if not the same) with Calycina parilis. What do you think? Many thanks again Enrique

Hymenoscyphus on Prunus cerasus old leaves

Hi to all: We have collected these fully white ascomata, very shortly stipitate, with no conspicous blackened base, up to 2 mm in diam. on petioles and veins of old Prunus cerasus leaves at 800 m of altitude. The spores are 1-nucleate. The paraphyses have some very little refractive Vb's, The asci HAVE NOT CROZIERS and the ectal excipulum have an angularis to very broadly prismatical textura. I think our finding is close to Hymenoscyphus immutabilis, but this species seems to be croziers at the base of the asci. Can you help us? Many thanks again

Pyreno on Populus wood

Hi again These small (up to 250 microns high) gregarious, scattered, seminmersed, ostiolate perithecia grew on very wet, semirotten wood of Populus. Only the free, somewhat papillate, neck and the apical region of the pyriform ostiolate perithecia are blackish by the existence of agluttinated short hair-like black cells. The rest of the fruitbody is smooth and subhyaline. The cylindrical, 8-spored, shortly stipitate asci, 90-105 x 8-9 microns, have a highly refractive, small, IKI negative apical apparatus, the stipes not disolving at maturity. Ascospores hyaline, smooth, 3-septate, 13-20 x 4.5-5.5, with many guttules, with no gel seath, no appendages. Paraphyses septate, apically attenuated. Have you some idea for it? Many thanks again

Eutypicolous Unguiculariopsis from Somiedo

Dear friends We have found these minute (up to 0.5 mm), very densely gregarious ascomata growing on stromata of Eutypa sp. on Fagus wood. There were hundred of fruit bodys filling the surface of the stromata that, on the other hand, were fertil. No anamorph. The ascomata, turbinate and attached by a narrow point, are vinaceous brown and the hymenial surface (and the excipulum too) is very pruinose by the existence oh hooked granulate hair-like paraphyses. The excipular and marginal hairs are hyaline or subhyaline with hooked and granulate neck, whith any refringence at their walls and they arise from the gelified and reddish brown cells of the excipulum. The asci are 8-spored, IKI negative, croziers positive. Some ascospores seem to make ellipsoid microconidia. I don't know an Unguiculariopsis species with these characters. ZHUANG (1988) describes U. parasitica and U. dimorpha as parasitic of pyrenomycetes, but their ascospores are different. Can you help me Thanks again

Strossmayeria ?

<div>Hello all,</div> <div>Recently I found this tiny discomycete on rotted hardwood in the Eastern US. It is white, discoloring to amber/orange, cushion-shaped, perhaps with a pseudostipe or narrowing at the point of attachment. Asci 120-150 x 12-14µm, IKI-. Spores very guttulate, 5-8 septate, 32-50 x 4-5µm. Paraphyses with irregular, swollen tips about 4-5µm wide at the widest point. One thing I noticed is that the base of the excipulum stains blue-green in iodine. This combination of features seems very similar to discussions of Strossmayeria basitricha I have read on this forum-- especially an exchange from April 2015 between Enrique Rubio and Zotto. Is this S. basitricha? Many thanks in advance.</div> <div>Ethan</div>

White fruitbodys on Ulex europaeus

Hi to all I have found these minute (up to 0.3-0.4 mm), gregarious, obconical, witish to amber downy ascomata growing on wood of cankers of Ulex europaeus at the sea level. The asci are IKI negative, 8-spored, with croziers. Paraphyses with small roundish colourless Vb's that stain in Crb. The hairs are long cylindrical, at least with 1 septum, hyaline, thin-walled, smooth, straight at the margin but coiled at the flanks, I don't know a good genus for this collection. Can you help me again?

Mollisioid fungus on cyperaceae

Hi again This fungus was found at the base of Carex sp. at 1700 m of altitude. Only six sessile apothecia, 0.4-20 mm in diam. over a well developped brownish subiculum. It has a mollisioid facies but the paraphyses have not refractive VBs and the asci are 4-8 spored. I think it is near to 'hemimollisia goldersbach! (Baral's Cubby) but the asci are shorter, the pore IKI rb, and it has less fusoid, shorter ascospores. By the other hand I feel this fungus could be close to Dennisiodiscus What do you think? Thanks again

Iodophanus on sand dunes

Hi to everybody Several times we have found this Iodophanus species (pulvinate ascomata up to 1 mm) on wet dead stems of gramineae (Ammophila, Elymus), Calystegia soldanella or Tortella flavovirens on calcareous sand dunes at the north of Spain. At the field we thought this was the common Iodophanus carneus but the ascospore morphology, the spore size and the much larger callose-pectic markings at the poles (up to 1 µm) were very different of those of I. carneus. Iodophanus granulipolaris Kimbrough has a similar ornamentation buy it is a coprophilous species with larger ascospores 24-26 x 15-16 and longer spore markings too. Have you some idea for this fungus? My pics have a low quality because the ascomata have not a natural more yellowish colour. Really they are pinkish or salmon-orange, with the typical colors of most Iodophanus. Thanks again

Amicodisca species on Quercus wood

Hi again This Amicodisca species grew on wood, under the bark of a 10 cm thick branch of Quercus petraea lying on the ground at 950 m of altitude. The apothecia, 0.2-0.4 mm broad, have a greyish brown hymenium and very pale yellowish hairs with lumps of a resinous sustance. They are macroscopically not well preserved due to the dry weather but the microscopical characters are in good condition. I feeel this fungus is very close to Amicodisca svrcekii a fungus with wide apical pore faintly MLZ +, spores ellipsoid to suballantoid, aseptate, containing 2 polar lipid guttules, 8-11 x 1.8-2.5 as described by Raitviir and Huhtinen. Two Baral's drawings show ascospores 8.5-14 (-17.7) x 2.7-3.2(-3.5) asci IKI 3bb and 8-10-11.5 x 2.6-2.9 asci IKI 3rb respectively and another one by Stip 10-14.5-3-4 asci IKI bb. In all these cases the ascospores show many small guttules and asci lacking croziers. But my collection have ascospores 6.1-9.1 x 2.1-2.9 with scanty guttules, asci not arising from croziers and in special way CONSISTENTLY IKI NEGATIVE EVEN AFTER KOH-PRET. For it I wonder if this character is sufficient as to consider this fungus as a different species Thanks in advance for your opinion

Leucoscypha sp. or something else?

Hello and greetings from Bosnia & Herzegovina and Sarajevo, this is my first post to ascofrance, but surely not the last. I`m curious about the Pezizales illustrated and shown bellow. I found three fruit bodies in the dry but still wet stream bank, accompanied by Trichophaea woolhopeia and Humaria hemisphaerica. Specimens were growing from the wet soil covered with the a little moss (not sure which species), and some kind of gametophyte, apothecia 0,3-0,5 cm in diammeter. Other micro data are mentioned at the drawing. Could be this some species of Leucoscypha, by the fusiformes shape of the ascospore it looks like possible solution for me, but I don` have proper literature, works and key for this genus... Full mature spore dimesions: 24-25x8-8,5 I would be very thankful if someone find solution (I still have one live fruit body in the box, for potential further neccessary analyses). Also I would appreciate if someone could mail me any litterature about this genus (besides L. semmi-immersa and L. patavina). Nedim Jukic

Pseudotrichia viburnicola - Update

Hi todos... two years ago I compiled all the finds of Pseudotrichia viburnicola. Since then we have now 4 new collections: it was Stip Helleman to find one during MellAsco 2011 in Le Bois de Sairé on Hedera helix: http://mycokeymycelium.blogspot.de/2011/05/mellasco-1-pseudotrichia-viburnicola.html next was Enrique Rubio who found it in Serín, Gijón, Asturias, Spain 13IV2012 on ?: http://www.asturnatura.com/especie/pseudotrichia-viburnicola.html then a find of Thierry Duchemin in Trouville, Normandy on Clematis connecting those geographically from southern England: http://www.ascofrance.fr/search_recolte/3412 And some days ago I found it in my mothers garden in Bonn, Germany where we enjoyed some Pentecôte holiday. It grew there on a dead twig (on the ground) of most probably Rosmarinus (some pictures attached, an updated map of distribution as well). I wish all of you who will meet in Somiedo a fruitfull and friendly foray which I sadly cannot join. New Spanish records of Ps.v. are welcome... ;-) Best regards Martin

Hyphodiscus/Cistella on old stromata of Hypoxylon

Can anyone help with these gregarious, small (up to 0.3-0.4 mm) sessile, white to amber, slightly gelified apothecia growing on old stromata of Hypoxylon grex rubiginosum? I don't know if the sustrate is reddening because the host is red. The hairs are very difficult to dissociate and they are hyaline, long cylindrical, with no clavate and verrucose apices. Asci IKI red with croziers. Paraphyses with some colourless Vb's. I think could be an Hyphodiscus species, maybe the Hyphodiscus 'cistella' of Baral's folders but perhaps it could be Nannfeldt's Cistella geelmuydenii. Or these two fungi are conspecific?

Hi again These gregarious, small (up to 0.6 mm), shortly stipitate and fully white ascomata are firmly attached to the aerial parts of bryophita that grows on Pinus wood. The material was sent to me by M. Tapia from Navarra (NE Spain). The asci are IKI negative and they have croziers (+). The ascospores are small and smooth. The paraphyses have some colorless VB's. Ectal excipulum with textura globulosa to prismatica with any gelified tissues. The margin has not differenciate hairs, only chains of cells with clavate and smooth end cells. We think perhaps this fungus is close to Pezizella muscicola Graddon, but the original diagnosis seems to be short and very incomplete.... What's your opinion Many thanks again Enrique

Pachnocybe albida?

On a decorticated branch of Fraxinus I found a white colony of hypho's Witn the microscope I saw synnemata of 400x17oµ and hyaline conidia of about 22x15µ. Conidia seemed to be solitary.Conidiophores were subhyaline and not markedly branched.Hyphae were 2µ thick. Could it be Pachnocybe albida?

Ayuda con un ascoma diminuto

Hola. Unos diminutos apotecios con forma de grano, de color anaranjado claro, de entre 0,8 a 1,3 mm. de diámetro, brotando de manera dispersa sobre unas hojas en descomposición ya bastante degradadas de planifolio tropical indeterminado, fotografiadas en la zona de Laguna Bávaro (República Dominicana). Excípulo medular y excípulo ectal muy parecidos, con hifas filamentosas muy entrelazadas. Ascos octospóricos, unitunicados, inoperculados, al parecer sin uncínulos en su base y con aparato apical que no reacciona al Melzer (-). Paráfisis filiformes, hialinas con múltiples septos, sin ensanchamientos en el ápice y generalmente curvados. Ascosporas elipsoidales, de pared gruesa con granulaciones en su interior, con unas medidas de las esporas libres de: (11.6) 12.3 - 14.8 (15.8) × (8.2) 8.4 - 9.8 (10.5) µm Q = (1.3) 1.35 - 1.58 (1.6) ; N = 30 Me = 13.4 × 9.2 µm ; Qe = 1.5 Cualquier sugerencia que pueda apuntar en la dirección correcta será bien recibida. Muchas gracias de antemano. Saludos cordiales.

Mollisia on Typha

Hi to all These small (0.3-0.6 mm) gregarious, sessile, not really cupulate apothecia were found on Typha old leaves at 1350 m of altitude. The excipulum is brownish black and they have not conspicuous marginal elements. Any crystal we have seen in medulla or excipulum. The ascomata are KOH yellowish. Ascospores strongly clavate with well visible gel sheath around fresh discharged ascospores. It seems to be close to Mollisia hydrophila that I found regulary on Phragmites at the sea level, but this species are paler ascomata with many crystals. Have you any idea for help me? Thanks again

Tarzetta sp

Hola a todos I found this small Tarzetta that seemed strange to me from the beginning, different from the T. catinus I have seen other times. The size is very small, the largest specimen is 13 mm in diameter, the ascocarp is sessile and the hymenium is more grayish than the excipulum. Also the habitat is different from the one I usually find T. catinus, this time it is in muddy soil, next to a stream with Quercus ilex, the PH of the soil is acidic. I have been looking for possibilities and I have found a taxon that I did not know called T. quercus-ilicis. What is your opinion?. If there is any microscopic difference with T. catinus I could look it under a microscope

Pyreno? 130523 779

Good afternoon Do you know what this "Pyreno" could be? In Acer leaves, surely A. monspeliensis. They are soft black dots, bulging when hydrated, tiny, which occupy the entire width of the leaf, as you can see in the photos. It doesn't look like a classic Pyreno, it probably isn't. The asci have a curious apical apparatus, very marked, but it is inamyloid. All asci I've seen have that irregular shape on the walls, I assume they're alive, although it looks like they're not. Spores are 2-celled, with 4 large LBs, 2 per cell, and hyaline conical appendages at the ends. Orienting myself for the spores I have gone to the genera Anisomeridium, Naetrocymbe, Lophiostoma, Vaginatispora, Lophitrema, Pseudocoleophonea and Wettsteinina, but I don't see anything like that. These are the measurements: Spores (15.5) 16.1 - 17.4 (18.3) × (4.1) 4.7 - 5.3 (5.6) µm Q = (3) 3.1 - 3.6 (4) ; No. = 38 Me = 16.7 × 5 µm; Qe = 3.4 Asci (60.1) 60.6 - 72 (83.9) × (10.8) 11.8 - 14.5 (15.6) µm Q = (4.2) 4.4 - 5.7 (6) ; No. = 42 Me = 67.1 × 13.3 µm; Qe = 5.1 Thank you so much.

Sporomega/Colpoma on Cistus

Hi again What about this Sporomega/Colpoma growing on dead wood of Cistus ladanifer lying on the ground at the SW Spain? The ascospores are 1-septate with a gel seath and an apical globule. Paraphyses with conspicuous Vbs stained blue by Cresyl blue. No yellow KOH reaction or only greenish on the dark, marginal, elements. This collection agrees with Guy Garcia's GG 04040402 and GG 05041001 from 2004 and 2005 on Calluna and Castanaea wood. But my spores are only 1-septate (not 3-septate) and lacks de yellow KOH reaction (saids 'as some Mollisia species'). Do you now some news on this fungus? Thanks again

The golden light ascospores are (1-)3-septate, the second cell slightly enlarged, with obscure apical conical appendages. It seems to match with the plate 0506 in last Bjorn Bwergen's book on Pyrenomyecetes, under the name Leptosphaeria scitula on Chelidonium.

Xylariaceous fungus on Salix branch

Dear friends Under a melanized thin, blackish, clypeoid pseudostroma they are these very small, roundish, glabrous, ostiolate perithecia up to 175 microns in diameter. Single or in groups up to 18-20 confluent perithecia with ostioles that allways are not collectivelly erumpent. I have not seen a true stroma and the peritecia are not in valsoid configuration. The fungus grew on a corticated branch of Salix lying on the wet ground periodically covered by the fresh water of a lake, together with Lophiostoma appendiculatum. The asci are shortly stipitate, up to 90 x 7 (pars sporifera up to 70), 8-spored, with an apical apparatus deeply blue in IKI and Melzer. The brownish fresh ascospores have a conspicuous sigmoid and oblique germ slit; appendages or slimy sheath are absent. With the keys on Xylariaceous fungi I arrive to the genus Anthostomella but I don't know a good species that fits with my collection What do you think? Thanks again

Pyrenopeziza on very wet hardwood

Hi to all On very wet hardwood my friend M. Tapia was found this Pyrenopeziza with white to amber pallid sessile ascomata up to 1 mm in diameter, attached by a narrow point to the sustrate. They are discoid, aplanate, never deeply cupulate and their margins are not pilose. The excipulum has the same color than the hymenium. Asci whit conical apices IKI b not of the Hymenoscyphus type, close to the Calycina type, 8-spored, with croziers. The ascospores are clavate with a low lipid content. Paraphyses without conspicuous refringent Vb's. The excipulum is made by an angularis-subglobulosa hyaline texture becoming prismatica in the flanks and towards the margin. Hyaline short clavate hairs make the apothecial margin. I think is not P. dilutella but I don't know a species that fits well with this collection. Have you some idea ? Thanks again

Les clusters (8 spores) 40-44 x 12-15 et les spores 15-16 x 6,5-7, avec un (sub) reticulate pattern. J'avais pensée dans S. eleutherosporus Brumm, mais je ne suis pas sure. Merci de votre aide.

Confirmation Nemania maritima

Hi Pyrenomyceto found on branch dead of Quercus ilex, bright, subsumerged perithecia. Found in a Holm oak forest at 100-150 m from the Cantabrian Sea, with clear saline influence. Perhaps being somewhat immature, I have not observed germination pore. It is the closest that I find in http://pyrenomycetes.free.fr/ Thanks.

Unknown pyreno on wood

Hi everybody, I need your help again. I continue to find this species on decidious wood and old, thick rubus stems. It is very small with a size of 0,2 mm, becoming superficial, gregarious. Spores hyaline without septa, but I'm not sure if they become 3-septate with age, (19-23) 21,33 x 4,25 (4-5) µm. Asci 85-101x6-8 µm, IKl negative, biseriat with croziers. Thanks Maren

Rutstroemia??

Hello everyone, on November 26, 2020 I found an asco growing at the base of presumably Carex arenaria. The site is located in the gray dunes in Koksijde, Belgium (coastal area). The asco appeared in abundance and I think it could be a Rutstroemia. Can somenone give me a clue? Spores: elliptical; filled at the poles with clusters of droplets; Av 16.34x6.50µm (N = 17) Asci: J-; uniseriated, 8-spored Paraphyses: filiform; cilindric; sometimes branched at the top; multiseptated; finely encrusted (?); diameter on average around 3.17 µm Hairs (?) or paraphyses on the edge: thick-walled; multiseptated; finely encrusted; tapered top; content colored. The photo series in the same order with a final image of the outer excipulum. All measurements were done in water. Kind regards, William

Gnomoniaceae on Rubus

Hi, I would like help with determination. Perithecia singly or small groups, distale zone absend, subepidermal, only ostiole prominent on surface, 620 um in diam., 300 um hight, ostiole 200-500 x 100 um, a long filiform, wall of ascocarp textura angularis, cells 15-20 x 10-14 um. Asci (37)40-43(48) x (7)7,6-9(9,5) um, ascospore biseriale, (12)13-15(16) x (2,8)3,1-4(4,6) um, Q=4,1, with polar apiculum 4-5 um long. I thought, that it is somewhere from the Diaporthales, but microscopic structures are diferent or somewhere with group Apiognomonia errabunda, Ophiognomonia rubi-idaei, Gnomoniopis chamaemori, comari or fructicola, but its microscopic structurs are by me different. Sub. dead stems of Rubus idaeus.

On the inner bark of Crataegus

Hi to all My friend F.J. Balda sent to me these gregarious, very small, turbinate, white to amber apothecia growing on the inner bark of Crataegus together with Orbilia xanthoguttulata. I don't know a good genus for this fungus that maybe reminds me the callorioid fungi. Asci IKI negative, with croziers. Paraphyses with clavate tips and without Vb's. Excipulum with + or - roundish hyaline cells. Marginal 'hairs' hyaline, clavate, smooth, with any content. Have you any idea? Many thanks again

Ascobolus de esporas esféricas

Hola. He encontrado estos Ascobolus que no consigo identificar. ¿Alguien los conoce? Gracias. Apotecios marrones, hasta de 2 mm, creciendo sobre tierra rodeada de excrementos de conejo, en principio ovoides sin exponer el himenio, más tarde rompiéndose la parte superior para exponer el himenio, con las ascas maduras sobresaliendo por encima. Ascas de (471,61) 533,37 - 649,45 (671,83) x (17,15) 71,23 - 97,07 (105,34) µm; Me = 591,59 x 81,92 µm, de paredes amiloides, operculadas, con 4 a 8 esporas. Esporas esféricas, de 28,47 - 35,94 µm; Me = 32,59 µm, al principio hialinas, después pasando por diferentes tonos liláceos y posteriormente marrones, uniseriadas o irregularmente biseriadas, envueltas en una masa gelatinosa, (en cuanto a la ornamentación, es un poco complicado, porque esta es muy variada. En su mayoría se ven casi lisas, ligeramente punteadas o con pequeñas estrías, que a su vez pueden tener pequeñas o grandes grietas. Aunque con menos frecuencia también aparecen verrucosas, con diferentes formas de las verrugas). Paráfisis cilíndricas, septadas, cubiertas por una masa amarilla en su parte superior. Saludos.

Pyrenopeziza lignicolous IKI-

Hello, wish you a merry christmas! In case someone drops by, I have this small Pyrenopeziza(?), on a piece of bark stuck 1m above ground between branches, on its inner side. The tree is Crataegus, I'm not sure about the piece of bark. Asci seem inamyloid, mostly inflated with a narrow base. Paraphyses cylindrical, VB-, not reacting in Baral's either. Only short brownish clavate cells on the margin. Soc. Orbilia xanthoguttulata. A row of trees between railroad and a field, riparian forest nearby. Am I in a correct genus? I've seen just a few lignicolous species in Bernard's key and neither was a good match. Maybe it froze a bit overnight, perhaps a damaged Mollisia would be a possibility too? Thank you in advance.

White asco on wood

Hi to everybody I'd like to know your opinion about these totally white ascomata, not yellowish nor reddening, small (up to 1.4 mm in diam.), gregarious, shortly stipitate by a stout and short stipe. The margin is glabrous an inrolled and the excipulum is white and pubescent. The ascomata grow on Betula alba wet wood at 1600 m of altitude. The asci seems to be IKI very faintly blue, 8-spored and they have croziers. Paraphyses have long cylindrical and refringent vacuoles. Ectal excipulum with textura angularis with many short polymorfic indiferenciate hairs. No basal blue reaction with IKI or Mlz. I can't see a clearly textura oblita in the excipulum and because of it I cannot say that my fungus is close to Bisporella subpallida. What do you think? Many thanks again

Orange asco on Rubus leaves

Hi to everibody We have collected on previous years leaves of Rubus ulmifolius these strange orange to yellowish ascomata arising of veins and petioles. Apothecia are gregarious, very small, up to 200 microns, and they are barrel shaped, columniform, later substipitate, turbinate and subcupuliform. No hairs or another piliform structures we have seen in the margin or the excipulum. Ascospores are filiform and up to 3-septate at maturity. Asci IKI b, croziers unknow. The paraphyses have allways some refractive vacuoles at their apices. Excipulum maybe with textura porrecta. We don't know what genus agrees with our collection. Can you help us? Many thanks again Enrique

Hi, May be somebody more experienced can help me. Is it possible that these pictures show Kretzschmaria deusta in a not yet mature (black) state? I know only bright whitish-gray anamorph form and completely black stoma. I've never seen something in between. Some pictures of stromatal surface like in http://mycology.sinica.edu.tw/Xylariaceae/frames.asp?qrySectionName=Kretzschmaria&qryIDString=k004&qryPart=t may give some hope?

Xylaria from the Algarve

I found only this one perhaps premature, but full ripe stroma. It is small, only about 1,3/0,8 cm in the dried specimen. 24.02.2023, Portugal, Algarve, near Monchique seemingly on the ground, but possibly connected with wood (most likely Quercus suber), in the margin of a small animal hole in a small canyon to a rivulet), in Quercus suber-forest (with Arbutus u.a.) With the key of Jacques Fournier I end at Xylaria longipes, with a fitting spore size. But: there is no Acer in wide surrounding, and the specimen looks very different from everything I by now saw as X. longipes. The germ slit of the spores is straight in my specimen (siee last foto). Who can help further? Yours, Lothar P.S. We found also X. violaceorosea on Castanea, and X. cf. putaminum on Olea stones (form with small spores fitting X. oxyacanthae) - and a lot of X. sicula

Lophodermium sur Quercus

Hello This gnomoniaceae grows abundantly on leaves of Quercus. Size: 350 - 400 x 280-350um. Neck 900-1300 x 45-50. Asci: 30-33 x 9-13um. Apical apparatus 2um Spores: 13-15 x 2-3um, noncentral septum (60% -40%). With small appendages (2-3um) at the ends. Initially I thought it was Ophiognomonia setacea, but lacks the central septum. It looks like gnomnia incrassata, but the neck is long and slightly smaller spores, and the host is Quercus. Do not know whose it is? Can anyone identify the species?

Black balls on Ulex

Hi Forum The ascomata of this fungus grew on corticated wood of Ulex europaeus, making cleistothecia (apparently non-ostiolate), blackish-brown, up to 0.5 mm in diameter, erumpent, isolated or coalescent and more or less spherical. The evanescent asci are claviform, pedicellate and contain (2-3-)4 dark brown spores with an apical pore, probably also monosporic since some excessively large spores may be seen. At the end, the contents of the ascomata are powdery and consisting of a large cluster of spores and the asci disappear. I wonder if this fungus could be well accommodated in the monospecific genus Boothiella, although it is different from Boothiella tetraspora, with larger cylindrical asci and larger and different spores. Many thanks in advance for your opinions.

Strange greenish fungus on Vaccinium

These very small (100-300 µm), erumpent, greenish, somewhat pulvinate apothecia were found, by chance, under the bino, between ascomata of Pezicula myrtillina and Gibbera sp, on thiny terminal branches of Vaccinium myrtillus at 1700 m of altitude. The apothecia are fringed by a crown of sparse hyaline subacute hairs, with somewhat partially glassy solid walls, IKI negative, that don't dissolve in KOH. The 8-spored asci are IKI negative, arising from croziers. Paraphyses without VBs. Ectal excipulum globulosa to prismatica with strongly pigmented greenish walls. The peculiar ascospores 1(-2) septate. I feel this fungus could be into the Naevioideae, perhaps close to Chaetonaevia. Have you some idea for help me? Thanks again

Mollisia on grasses

This Mollisia species grews at the very humid basal parts of grasses (maybe Molinia caerulea) in peat bog soil at 800 m of altitude. The ascomata, up to 1 mm, grew on a + or- developed brownish subiculum and the hymenium is yellowish or amber. KOH is clearly yellowish (+) but not strongly yellow. Ascospores are eguttulate. Asci IKI b, up to 75 x 8, 8-spored, with croziers. Paraphyses have cylindrical Vb's or fragmenting refractive Vb's, Medullary excipulum with hyaline or subhyaline textura intricata. Ectal excipulum with vesiculose or angular hyaline or palid yellowish cells. Marginal cells are clavate, hyaline and slightly gelified. I think in Mollisia citrinopigmentosa but 'my spores' are bigger What do you think?

Small fruitbodys on old burned sandy soil with Ceratodon

Hi to everybody I'd like to know your opinion on these scattered, small (0.2-0.5 mm), subturbinate, very shortly stipitate, semitranslucent, not gelatinous, glabrous apothecia, growing on sandy, old burned soil, among the moss Ceratodon purpureus, together with apothecia of Octospora rustica.. The hymenium and the excipulum are covered by a thin gelatinous, colorless layer making an epithecium. Asci 8-spored, IKI negative, with open, big, croziers as in many Orbilia species. Paraphyses with a small, roudish vacuole that does not stain in Crb. SCBs seem to be also present. Excipulum of hyaline, pyriform to roundish cells elongated towards the margo. Perhaps the free ascospores make narrowly ellipsoid microconidia. I don't know what genus could be good for this fungus. Maybe it belongs to the Epiglia-Mniaecia complex? Thanks again for your help

Peziza fimeti

Salut, ces Pezizas, je les ai reprises sur des excréments bovins. Un aliment pourrait se fréquenter(se soigner) de la Peziza fimeti, tant par la grandeur esporal, comme par les caractères macroscopiques (aucune ne dépassait les 2 cm), en révisant une bibliographie je ne trouve pas la différenciation claire avec la Peziza vesiculosa. J'attends vos opinions. Merci beaucoup. Un salut. Alberto Román Hello these Pezizas, I gathered them on bovine excrements. Fodder might treat about the Peziza fimeti, so much for the size esporal, since for the macrocospic characters (none was exceeding 2 cm), checking bibliography I do not find the differentiation clear with the Peziza vesiculosa. I wait for your opinions. Thank you very much. A greeting. Alberto Román.

Récolte 2021-05-25

Bonjour, Je nécessite votre aide pour cet asco que je n'arrive même pas à rattacher à un genre. Récolte le 25/05/2021 – Lardy (91) – France – Etude sur matériel frais vivant. Sur une brindille (diamètre 1mm) d'essence inconnue entre une pelouse sablonneuse calcaire et un bosquet (j'ai vu des Corylus). Agrocybe pediades et Tulostoma sp à proximité. Apothécies d'1mm de haut, stipitées, en coupes ouvertes (la marge enroulée vers l'intérieur sur la photo est due à la chaleur de la lampe de la binoculaire). Les ascomes sont distants de 15mm les uns des autres sur la brindille. L'hyménium est beige/jaune pâle, la face externe blanche semble veinée, difficile d'évaluer le relief avec mon matériel. Je n'ai pas vu de poils sous la bino (excusez la qualité des photos...) -spores cylindriques à contenu lipidique variable, le plus souvent 3-septées mais aussi 4-septées. Elles semblent posséder une sorte de périspore incolore/transparent assez épais ; 15 mesures dans l'eau sans compter ce périspore = [20-30]x[4-5]µm. -asques octosporées IKI+ et paraphyses moniliformes renfermant de nombreuses petites guttules. Difficile de faire une coupe propre et nette, je peux réessayer si nécessaire. Merci d'avance pour votre aide, Pierre-Yves

Asco sur bois de Tilia

J'amairais conaitre votre opinion sur cet petit ascomycete (ascomata: 0.2-0.5 microns), sessile ou subsessile, avec l'hymenium amber-verdatre- brun, frangée de poils hyalines ou legerement brunatres dans la maturesse, avec les extremites epineuses (type Cistella?). L'excipulum est gelifiée, avec textura porrecta et les asques (jusqu'a 60 x 7) ont des crochets, 8-spored et IKI rougeatre ou bleu-rougeatre. Spores 5.7-8.3 x 2.8-3.4. Il croit de maniere gregaire sur le bois de Tilia mort. Merci de votre aide I'd like to know your opinion about this small asco (ascomata: 0.2-0.5 micr.) that grows on Tilia sp. wood. Sessile or subsessile. Hymenium umber-greenish-brownish. Excipulum with gelified textura porrecta. Asci up to 60 x 7, 8 spored, with croziers, IKI r or rb. The distal element of the hairs are spiny (Cistella-like?) . Spores 5.7-8.3 x 2.8-3.4. Many thanks for your help.

Biscogniauxia sp.

I am not sure how much you can help me with these images found on a dead tree presumably Quercus sp. The fungus manifests itself as widespread black stromata forming large irregular patches often in longitudinal patterns. The surface is minutely bumped by almost-microscope pycnidia. I have not collected a specimen, but I can if revisit and collect, nonetheless the cross section of the stroma reveals some data that might be helpful So to conclude I assume this is a Biscogniauxia sp. and wonder if from the photos we can determine the species - maybe Biscogniauxia mediterranea ? Tnx

Pyrenopeziza (?) sur Cirsium

Voici de nouveau une récolte effectuée à Belcaire lors des journées ascos, sur tige morte de chardon (peut-être un Cirsium), et qui me pose problème malgré des caractères assez remarquables. Apothécies discoïdes, à hyménium gris sombre, surface externe noirâtre avec un liseré gris pâle au niveau de la marge. Ø 0,5-1 mm Asques fusoïdes, octosporés, avec crochet, 48-63 × 6-7 µm, à anneau apical IKI + (bb). Paraphyses lancéolées à spatuliformes, pluriguttulées mais sans réfringence, non cloisonnées, 57-62 × 4-5 µm. Spores fusiformes, hyalines, contenant quelques guttules, non cloisonnées, (14) 16-19 × 2,7-3,2 µm. Excipulum de textura globulosa/angularis à cellules noirâtres, se décolorant vers la marge et devenant plus allongées (cf. photo). En suivant la clé de Bernard Declercq du genre Pyrenopeziza, on s'approche de P. carduorum mais cela ne colle pas pour les paraphyses et les spores de cette espèce sont un peu plus guttulées me semble-t-il. En suivant la clé des Dermateoideae de Nauta & Spooner (1999), on arriverait, selon moi, sur le genre Mollisiopsis. Mollisiopsis lanceolata (= Pyrenopeziza l.) présente bien des paraphyses lancéolées mais pas aussi fortement que celles-ci et ses spores sont plus petites... Donc j'arrive à des impasses. Merci pour vos suggestions.

Orbilia on soaked wood

After some time I tried an Orbilia again.... I found it today on a piece of rotten soaked wood, lying in a small creek, half submerged. The few (4-5) apothecia are very fragile and light apricot in colour. Asci are 8 spored, uni- to biseriate, IKI- and with a furcate base. (28-34.5 x 3.2-39 µm, without base) Paraphyses are covered at the tip with a gelatinous mass, shape is capitate and there are septa in the stipe. The spores are ovoid to fusiform featuring a prominent refractive body. (3.2-4.2 x 1.3-2 µm) I believe that I have found O. coccinella two times before. Is it the third time? Regards, Martin

François Bartholomeeusen, 17-05-2016

is it var. leuconica or bulbopilosa?

Dear forum, I found a few fruiting bodies on a dead twig of Myrica gale, partially decortated. Nearby grew several fruiting bodies of Incrucipulum sulphurellum FRB: disc shaped, 237 x 191 µm, with long curling hairs Spores: oblong: 5,56-8,1 x 1,89-3,29 µm Q= 2.93 with some drops at the poles Asci: cylindrical, 23,64-28,83 x 3,37-5,44 µm in melzer apex slightly blue; no croziers Paraphyses: filiform, sometimes forked: 26.57 x 2.43 µm Hairs: thick walled, broad base and ending twisted like a corckscrew; 44,82 µm long, base 4.35 µm, wall: 1.91 µm Thanks to this forum I think it is Hyaloscypha leuconia. I have no literature, can anyone help me to determine whether it is the var. leuconica or var. bulbopilosa? Thanks in advance, François Bartholomeeusen In annex one picture of the curling hairs and one document

Strossmayeria on Rubus canes

Hi to all Few days ago I have found these small fruitbodys growing on old wet stems of Rubus grex fruticosus at the sea level. Here is my description of this fungus. Apothecia superficial, gregarious, scattered among the blackish brown setae of the conidiophores of a dematiaceous mould (Pseudospiropes?), narrowly turbinate, more or less gelified, whitish to amber color, up to 0.30 x 0.25 mm, substipitate on a short and stout pseudostipe 0.12 high and 0.15 broad. Hymenium flattened, smooth or only slightly pruinose. Margin involute, glabrous, that exceeds the hymenium level. Excipulum glabrous and whitish. Asci narrowly clavate, inoperculate, unitunicate, 137-182 x 19-20 µm, 8-spored, IKI negative, arising from croziers. Ascospores biseriate, hyaline, smooth, with many small LBs, very polymorphic, ellipsoidal, cylindrical, subfusoid, obovoid, clavate, (19-)30(-38) x (5.2-)6.9(-9.8) µm; Q = (1.9-)4.6(-6.9), with 3(-5-6) cross septa only well visible in Melzer's reactive or congo red. A more or less smooth and complete gel sheath surrounds the fresh ejected ascospores. Paraphyses filiform, septate, not enlarged at their tips or only up to 2-2.5 µm, with cylindrical Vbs. Ectal excipulum textura oblita with cylindrical, elongate, septate, hyaline cells 2-2.5 µm, with a thin gel layer between them, wider at the apothecial base. Medullary excipulum is indistinguishable The basal region of the ascomata stained blue in IKI. All the apothecial tissues extrude in fresh condition a bright yellow fluid in KOH 10%. After reading Iturriaga & Korf's paper I don't know a species that fits well with this fungus. Could you help me? Thanks again

Peziza sur sol boueuse, fragments de Veratrum album et bois de Salix sp. (1700 m)

Bon soir mes amis du Forum: Je vous prie une idée avec cette Peziza: Ascomata cupulées, sessiles ou subestipitées, jjusqu'à 2,5 cm de diamètre, avec l'hymenium de couleur jaunâtre olivacée, mélangée avec du brun, qui envahit progressivement la totalité de celui-ci. Excipulum plus claire, légèrement furfuracée de brun près de la marge, qui est denticulée dans les très jeunes exemplaires. Chair jusqu'à 1,5 mm d'épaisseur, avec des tons olivacés dans des exemplaires frais et jeunes, et qui ne semble pas émettre latex après être exposé à l'air. Spores largement elispoidales, avec un contenu jaunâtre et homogène, sans guttules, avec des murs un peu grossis et optiquement lisses (bleu cotton). Après être expulsé des asques elles présentent fréquemment les restes d'une enveloppe gélatineuse et hialine (perisporium) qui se détache seulement partiellement, en manière d'apéncice globuleuse collé à l'un de ses parois, de (19-20-21-(22) x (11-12-(13.5) m; Q = 1.6-(1.7). Adques cylindriques, pourvus de crochets, 275-337 x (12-17-(20) m. Des extrémités intensément bleutés dans IKI. Paraphyses multiseptées, cylindriques, sans des segments moniliformes, l'apical brusquement dilaté jusqu'a x 10 m. Elles ne semblent pas contenir un pigment intracelular. Le pigment, de couleur brune - rougeâtre ou brune - olivacée, semble être fixé dans les dites extrémités, en manière d'une incrustation extrapariétale. Excipulum médullaire avec un mélange d'hyphes vesiculeuses (textura globulosa) et d'hyphes plus ou moins cylindriques, larges et plus ou moins entrelacées (une textura intricata). Excipulum ectal avec une claire textura globulosa, d'hyphes vesiculeuses jusqu'à 62-70 m d'un diamètre avec pigmentación jaune - olivacée. J'ai pensée a Peziza granulosa var. boudieri Cooke (= P. boudieri (Cooke) Donadini, mais j'ignore si je suis erroné. J'aimerais connaître votre opinion. Merci en avant

¿Ascas biseriadas o ascosporas biseriadas?

Hola a todos, siempre me surgen dudas de que sería más apropiado decir. Veo trabajos donde aparece en la descripción de las ascas, diciendo "ascas biseriadas", pero en otros trabajos aparece en la descripción de las ascosporas, diciendo "ascosporas biseriadas" ¿Qué sería más apropiado? ¿Es una propiedad de las ascas, o de las ascosporas? Gracias. Salvador.

Nitschkia broomeana

Hola a todos. Quería que me confirmasen si estoy en lo cierto con la identificación de este hongo. Gracias. Ascomas de (363,98) 376,87 - 534,18 (565,52) µm, generalmente gregarios, negros, con la superficie rugosa, algo cuarteada y con algunas espinas muy pequeñas, creciendo sobre la corteza de una rama muerta de Quercus ilex. Ascas de 97,35 - 131,67 x 17,92 - 20,53 µm, unitunicadas, multispóricas, no amiloides. Ascosporas de (10,34) 11,05 - 13,68 (14,32) x (2,00) 2,30 - 2,65 (2,85) µm; Me = 12,23 x 2,47 µm ; Qe = 4,97, lisas, hialinas, cilíndricas, alantoides, con algunas pequeñas gútulas de aceite generalmente en los extremos y en algunos casos con un septo transversal. Yo pienso que es Nitschkia broomeana. Tengo entendido que lo normal es que tenga más espinas y que las medidas de las esporas sean algo mas bajas, pero supongo que esto entrará en la variavilidad de esta especie ¿estoy en lo cierto?. Gracias.

¿Saccobolus? ¿Ascobolus?

Hola. unos diminutos apotecios de color amarillo fotografiados el pasado domingo sobre excrementos de ganado vacuno, compartiendo espacio con Cheilymenia granulata, Ascobolus furfuraceus y Pilobolus aff. chrystalinus. Apotecios de forma globosa, de color amarillo, de entre 0,65 a 0,87 mm. de diámetro, con unas ascas emergiendo donde a 40 aumentos ya se pueden apreciar bien las esporas. Hifas del contexto bastante uniformes, hialinas, septadas y con una anchura de entre 3 a 4,3 micras. Asos octospóricos con una longitud que excede en muchos casos de 300 micras y con una anchura de hasta 80 micras. Esporas anchamente elipsoides, hialinas en la juventud para ir coloreándose de violeta oscuro con el desarrollo, con una vaina mucosa en su alrededor, esta vaina visible ya en muchos casos dentro del asca y que se tiñe con el Rojo Congo, con algunas estrías irregulares en su superficie en función del plano observado, y con unas medidas de: (55.9) 58 - 62.3 (63.4) × (29.5) 30.6 - 33.2 (34) µm Q = (1.8) 1.83 - 2 ; N = 30 Me = 60.4 × 31.8 µm ; Qe = 1.9 Estas enormes medidas esporales no me encajan con ninguna especie de Saccobolus, y aunque si que tenemos el Ascobolus macrosporus y el Ascobolus grandisporus con esporas de gran tamaño, en ambos casos las esporas son esféricas, con lo que hasta he llegado a dudar de que se trate de una Ascobolaceae. Cualquier sugerencia será bien recibida. Muchas gracias de antemano. Saludos cordiales.

Pulvinula miltina possible?

Yesterday I found some Pulvinulas growing on clay-rich soil near a pond. I thought the species might be Pulvinula convexella (= P. constellatio), but the spores are fairly small compared to some sources (although there seems to be broad variety between different sources). I'm thinking about the possibility of P. miltina. I measured 15 spores from a spore print in water and the diameter was 14-15 microns. There are many fresh expert approved sightings of P. miltina in the Danish svampe.databasen.org. In GBIF there are sightings from European countries and Australia and New Zealand. But I also found a comment by Nicolas Van Vooren on this forum from few years ago that P. miltina is an Australian species and possibly endemic. So has there been some new study that has cleared this matter or is there still confusion about this species?

Je ne trouve pas ce terme dans les différents glossaires de mycologie, sauf celle-ci dans wikipedia : <a href="http://en.wikipedia.org/wiki/Crozier_(mycology">http://en.wikipedia.org/wiki/Crozier_(mycology</a>) Quelqu'un peut-il montrer une image de ce qu'il faut voir à la micro ?

Orbilia alba with adhesive knobs

Hi together I wish to show some results about the very interesting Orbilia collection made by Enrique, from Eucalyptus bark in Asturia. I identified this species as O. alba, but later found that while this Orbilia became senescent, another Orbilia developed with similar though wider spores with a larger, globose, central apical SB, which I identify as O. cotonoeastris (a close relative to O. rectispora and O. pellucida which JP Priou knows). Now, I believe that to O. alba belong the adhesive knobs which trap arthropods, and also the Drechslerella anamorph with very thick 2-septate conidia and constricting rings. On the contraty, O. cotoneastris is a member of series Dactylella and has cylindrical multiseptate conidia and no trap organs are known. The problems here are manyfold: The apothecia of O. alba are now decayed and no pure culture possible. We tried to cultivate the trap organs, but the result is still unsure. So, if this Orbilia shows up again I would be very glad to receive a further sample. While the apothecia are gone, the adhesive knobs become more and more, and I added small spiders and mites. Actually, within a few seconds the legs stick to the knobs. Often the animals succeed to get free after keeping unmoved for some minutes to let me take pictures, but one small mite was captured yesterday and is now beginning to get overgrown by the hyphae. The hyphae of the knobs with their Woronin bodies resemble well the anchoring hyphae of O. alba, but the last evidence should be brought by a culture. When the animal legs touch the knobs, several knobs get glued together, and then the animal needs threefold power to get free. Here an insect that was captured possibly 2 days ago and is now already overgrown by the hyphae.

HYPOGEOUS

What is this ? Pachyphloeus ligericus cf. ?

Josep Torres, 01-04-2020

Alguna idea?

Hola. En estos momentos que debemos quedarnos todos en casa, debemos aprovechar para rescatar viejos temas que no logramos identificar en su momento, os presento uno del año 2016. Las imágenes fueron tomadas el 23 de Marzo de 2016 en cauce fluvial, donde predominaban los chopos (Populus). Pequeños cuerpos algodonosos con un corto pié, de color blanco y con un diámetro de tan solo entre 0,16 a 0,25 mm., estos compartían espacio con unos ejemplares de Nectria peziza (en la imágen abajo a la derecha), aunque no creo que tengan ninguna relación con la especie descrita. En su microscopía solo destacar unas hifas dispuestas paralelamente, ramificadas y terminando en unas hifas conidiógenas irregulares, con septos simples, con una anchura de entre 3,2 a 3,5 µm y con ensanchamientos que pueden llegar a las 6,2 µm. Conidios entre ovoides y elipsoides, con una forma de limón, con muy tenue contenido en su interior y unas medidas de 18,2 a 21 X 12,9 a 16,1 µm. Cualquier sugerencia será bienvenida. Muchas gracias de antemano. Saludos cordiales.

unknown genus / species

Hello all. I hope someone can help. Found on 19.03.2022 on hardwood. Fruiting body approx 1mm large, hook+ IKI+ Unfortunately I did not find any spores. On the last picture there could be a spore on the left edge, but I am not sure. Maybe someone has an idea in which genus I should look.

Apotecios turbinados no identificados

Hola a todos/as Adjunto fotos macro/micro de unos pequeños ascos turbinados no identificados, están recolectados en el sur de España en los márgenes de un camino con Eucaliptos (Eucalyptus camaldulensis), en el suelo húmedo con pequeños musgos. Apotecios más o menos turbinados, de hasta 2,5 mm, de color marrón/rojizo y mechones de pelos en la parte externa. Esporas globosas cuando son inmaduras, después anchamente elipsoidales, con envoltura gelatinosa, de: 21,5 [22,7 ; 24,2] 25,5 × 17,8 [18,6 ; 19,6] 20,4 µm, medidas realizadas dentro de las ascas, de paredes gruesas, con un núcleo y granulaciones en su interior. Ascos octospóricos, algunas con el ápice capitada, con croziers ( amiloidad no testada) Paráfisis con grandes gutulas, con septos y ápice fuertemente engrosado Excípulo medular y ectal con textura globulosa/angularis Pelos de color amarillo, septadas, de paredes gruesas y con el ápice terminado en punta. A ver si me podéis ayudar con esta especie, yo ni tan siquiera me acerco al género. Gracias anticipadas y un saludo a todos. Curro Valencia

Roseodiscus aff. formosus

Hi, I collected this discomycete at approx. 2400 m a.s.l. and I think it has strong similarities with this Roseodiscus aff. formosus: https://drive.google.com/drive/folders/0B5SeyOEkxxZhXzZkNXRMSDFIVzA?resourcekey=0-XZegZviwmZP_xJiG2vNF5g Spores measure about 10–13 x 3–3.5 µm, croziers are present, the asci are IKI bb. Just wanted to share this interesting collection. Best wishes, Gernot

Elaphomyces cyanosporus ou persoonii

Bonjour. On m'a confié la détermination d'un Elaphomyces récolté ces jours sous Quercus pubescens, mesurant 18-30 mm de diamètre. J'hésite fortement entre deux taxons : E. cyanosporus et E. persoonii. Quels sont les critères objectifs pour séparer ces deux espèces ?

Josep Torres, 06-04-2021

Ni idea

Hola. Unos diminutos ascomicetos peludos, con forma esférica y color marrón verdoso, con unas medidas de entre 0,9 a 1,7 mm. de diámetro total, brotando en un pequeño tronco de arbusto indeterminado procedente de las labores de limpeza en un campo de cultivo, cerca de un cauce contínuo de agua destinado al regadío. En el mismo tronco y a unos pocos centímetros compartía espacio con unos diminutos ejemplares de Cephalotrichum microsporum. Toda la superficie externa repleta de largos pelos marrones al microscopio, con una anchura de entre 2,1 a 4,3 µm. con muchos septos, algunos bifurcados en la base, y con el ápice hialino y terminado con formas redondeadas. La superficie de las hifas mayoritariamente con finas granulaciones. Hifas del excípulo de textura angular, con unas medidas de 8.1 - 19.8 × 6 -14.6 µm. Al comprimir la muestra al eclosionar, del interior surgen una gran cantidad de esporas, aunque no pude observar ascas, por lo que probablemente sean quizás un producto de hifas conidiógenas. En las imágenes añado una del himenio por si puede dar alguna pista. Conidios o ascosporas de forma entre ovoide y cortamente elipsoide, con los extremos apuntados y en muchos casos como si las hubieran pellizcado, como en forma de limón, entre hialinas y de color marrón oscuro, probablemente por el estado de maduración, con una o dos grandes gotas lípidas en su interior y con abundantes granulaciones mas pequeñas, las medidas de estos conidios o ascosporas de: (9.2) 11.3 - 13.4 (15) × (8) 8.6 - 10 (10.4) µm Q = (1.1) 1.2 - 1.5 (1.7) ; N = 60 Me = 12.3 × 9.2 µm ; Qe = 1.3 Dentro de las Botryosphaeriaceae, lo más parecido que he encontrado sería ¿Diplodia?, también he buscado entre los Dothideomycetos sin nigún resultado. Cualquier pista que me pueda acercar a su identidad será muy bien recibida. Agradezco de antemano vuestra ayuda. Saludos cordiales.

Pleonectria

Hola a todos. Tengo estos peritecios que crecen en Pistacia lentiscus. Yo había pensado que podría ser Pleonectria virens, que también crece en alguna Anacardiaceae, pero no me termina de encajar, porque el hongo que os presento tiene las ascas más largas, uniseriadas, y las esporas no son hialinas. Supongo que Christian me podrá ayudar. Gracias. Peritecios de aproximadamente 0,5 mm de ancho, generalmente gregarios, cubiertos por una capa escamosa de color amarillo-verdoso, que vista en el microscopio está formada por cristales rojos, con el ostiolo visible más oscuro. Los peritecios en KOH reaccionan desprendiendo y coloreándose de color amarillo-anaranjado. Ascas de (92,79) 94,16 - 116,03 (118,02) x (13,77) 14,28 - 17,17 (17,96) µm; Me = 105,24 x 15,80 µm, con 5 a 8 esporas. Esporas de (12,65) 14,57 - 19,64 (21,06) x (8,52) 9,72 - 11,68 (12,38) µm; Me = 17,06 x 10,73 µm ; Qe = 1,60, muriformes, con el septo primario más señalado, de color marrón-grisáceo, o ligeramente verdosas, que en KOH se colorean intensamente de verde y les aparece un envoltorio gelatinoso (generalmente a las más inmaduras). Paráfisis mucho más largas que las ascas, hialinas, septadas, estrechándose en el ápice. Saludos. Salvador.

Asco on Hedera

Yesterday, during an inventarisation in Zoetermeer (The Netherlands) we found some ascomycetes on a leaf of Hedera. In my search to find the right species, I saw a topic on this forum which pointed to Lambertella tetrica. As far as I can see, all features seems to match my found. Am I right? Spores: 23-26 x 5 mu With kind regards, Anna

Tryblis arnoldii? No, Durella atrocyanea

Hello everyone I'm an amateur from Switzerland, this is my first post. I found this fungus on a dead branche at about 900m altitude. The closest fit I could find is Tryblis arnoldii, but im not quite convinced yet. The size of the asci differs quite a bit from the values given in Cryptogamica Helvetica 23. Also the Substrate doesn't really fit. It looks like Fagus or at least deciduous wood to me. Spores: 14.9 - 16.9 - 19.3 x 5.5 - 5.8 - 6.8. Q = 2.6 - 2.9 -3.4 n=14 Asci: ca. 90-100 x 13 IKI- There are also Conidiomata present which look kinda similar in color. I wonder if it's the same fungus. Any suggestions? Best wishes Philipp

disco immergé

Bonjour, Comment ne pas craquer devant ce joli disco jaune semi-immergé ou immergé dans un ruisseau ? Je le rencontre fréquemment et ne sais comment l'appeler. N'ayant pas trop d'expérience dans la matière, je ne sais vers quel genre me tourner. Précision sur mes photos, l'unité étant le micron, cela donne des spores de 20-23 x 12 µm avec des verrues remarquables. Le connaissez-vous ?

Iodophanus

Hello, this ascomycete grew in a city in Czechia, on soil, 215 m asl. Apothecia orange, up to 1.5 mm in diameter, smooth, sessile, rounded or slightly irregular. Spores 19.5-22.5 x 12-13.5 micrometers, ellipsoid, thick-walled, hyaline, ornamented with very fine warts, without guttules. Asci 235-260 x 32-35 micrometers, biseriate, longly clavate, in Lugol entirely blue. Paraphyses containing orange pigment, straight, quite densely septate, sometimes branched or with short lateral projections, 4-6 micrometers broad in the middle, 6.5-11.5 at the apex, terminal cell 23-43 micrometers long. Excipulum t. globoso-angularis, with cells measuring 17-46 micrometers in the longer dimension. I looked to literature at Kotlabaea, Cheilymenia, Boubovia and many others, but something was always wrong. I will be glad for your opinions. Thanks, Zuzana

Ombrophiloid fungus on peat-bog soil

Hi to everybody: Yesterday we have seen this lenticular to pulvinate totally whitish ascomata up to 5-6 mm in diam. that grows on Eriophorum angustifolium old leaves (and ericaceous host too) on very wet acid soil. The ascomata are sessile on a very broad base and they are glabrous. The medullary excipulum has a loose textura intricata without crystals that becomes very gelified at the cortex. I think the asci are IKI negative (or very faintly positive?). Croziers positive. The spores have a faintly gel sheath around them. I think is not an Hymenoscyphus species but I don't know a good genus for it What's your opinion?

Plectania rhytidia?

Good evening! My friend Matthias Theiss found a beautiful Plectania in Portugal, 15.04.2008, Lago de Albufeira, near Lissabon. The diameter of the ascocarps was 1 cm. Substrate were twigs of Eucalyptus lying on a slope at an artificial lake. The soil was sandy and covered with a forest of Pinus pinea and Eucalyptus, there were different kinds of fern and Arum. Accompanying fungi were Arachnopeziza aurelia, Phellinus pini, Pisolithus arrhizos, Laccaria tortilis. I enclose a foto and a foto of the spores. What do you think, is it Plectania rhytidia? Thank you for your opinion Hermine

Pseudombrophila leporum ?

Hola amigos: Hace unos dias recogí en excrementos de conejo silvestre una especie de Pseudombrophila que de acuerdo con las medidas esporales y con una clave que baje de internet hace unos años y que suelo utilizar me ha llevado a Pseudombrophila leporum, aunque veo que muy prooxima a esta puede estar Pseudombrophila misturae.Me gustaria saber si alguno teneis experiencia en estos dos tipo de ascomycete y como podeis llegar a diferenciar una de la otra.Si solamente existen diferencias microscopicas en en ancho esporal o hay algun que otro caracter diferenciador. Ahi os dejo una pequeña descripcion de la especie en cuestion: Pseudombrophila leporum¿¿ Ascomas de forma discoidal con la superficie aplanada o ligermente cóncava. De 1 a 3(-4 mm.) mm. de diámetro. Superficie lisa. De color marrón rojizo, a marrón dátil, mas oscuro en hacia el borde del apotecio..Margen poco diferenciado. Ascas cilíndricas, de hasta 150 µm de longitud, octospóricas, con el ápice no amiloide. Ascosporas de forma anchamente elipsoidales, uniseriadas oblicuamente dentro del asca, hialinas y lisas. Paráfisis muy numerosas, ramificadas con gran numero de septos , ligeramente infladas en los ápices y en algunos tramos de los septos intemedios . Excediendo en longitud de las ascas. Dimensiones esporales: L= (12.7) 13,4 -13,9 (14,6) µm A =(8,8) 9,3 –9,7 (10,2) µm Lm =13,7 µm A m =9,5 µm Qm= 1,4 Corología: Palencia.Carretera circunvalación Poligono industrial (Pa). 740 m.

Thuemenidium atropurpureum 261221 855 with hyaline and dark spores

Hi guys It is difficult to me to explan this in english, so I am going to write in spanish, sorry. El pasado 26/12 encontre nuevamente una pequeña colección de Thurmenidium atropurpureum, ya la tenía vista y estudiada del mismo sitio. Al intentar confirmarla al micro la sorpresa es que aparecen ascas con ascosporas hialinas, multigutuladas y sin septos, como corresponde a la especie, pero también numerosas ascas con esporas marrones, multigutuladas y con 7 septos, típicas de Geoglossum. Así que miré los 5 ejemplares de la muestra, habiendo esporas oscuras típicas de Geoglossum en 4 de los 5, sólo 1 muestra presentaba únicamente esporas hialinas. Los hechos son los siguientes: * Las ascas con ascosporas hialinas están vivas, y las ascosporas también. * Las ascas con ascosporas marrones están muertas, pero las ascosporas están vivas. * Todas las ascosporas vivas expulsadas espontáneamente de las ascas durante la observación son hialinas y sin septos. No se han observados esporas marrones y septadas expulsadas de las ascas, todas permanencen dentro de las ascas muertas. * En 4 de 5 ejemplares de la colección hay ascas con esporas hialinas y marrones. * No se trata de una contaminación, ambos tipos de ascas están intercaladas unas con otras en el himenio, y no estuve estudiando antes ningún Geoglossum. * El patrón de gútulas de ambos tipos de ascosporas, hialinas y marrones, es el mismo, alrededor de 18-20 grandes gútulas redondas, la única diferencia es que las ascosporas marrones tienen 7 septos. Hipótesis: 1.- Las ascosporas inmaduras de T. atropurpureum son oscuras y septadas y al madurar se vuelven hialinas y pierden los septos. Poco probable. 2.- Las ascosporas de las ascas muertas de T. atropurpureum se vuelven marrones y se septan, pero aún así siguen vivas. Más probable. ¿Alguien ha observado la presencia de esporas de Geoglossum en un Microglosum o Thuemenidium? Gracias por vuestras opiniones. Miguel Á. Ribes

etymologie

Bonsoir à tous, La dernière fiche d'ASCOfrance envoyée par Enrique ( superbe comme d'habitude !!! la fiche) et décrivant Dasyscypha calyculiformis var. latebricola a suscité chez moi deux questions: L'une d'ordre étymologique : que veut dire latebricola ??? mon dictionnaire latin du 19 eme siècle me donne : personne qui fréquente les lieux de débauche !! (Plaute). Pour un petit asco ça veut peut-être dire : qui se loge dans une cachette secrète ? ce qui, expliquerait pourquoi je ne l'ai jamais trouvé en Ardenne. L'autre d'ordre taxinomique : ce champignon est manifestement (pour moi ) un Capitotricha et je trouve bizarre que Enrique soit obligé de choisir un genre devenu obsolète (toujours à mes yeux) comme Dasyscypha ou Dasyscyphus. Est-ce par manque de synonymie prioritaire ? Pourquoi pas Capitotricha latebricola ? Ce serait une espèce à part entière elle me semble bien mériter l'honneur de ne pas être une simple variété. Qu'en pensez vous? Amitiés. Robert

Hypoxylon rubiginosum??

Dear all, This week I found this fungus, which I believe be Hypoxylon rubiginosum "species complex", but I would like to hear some additional (expert) opinions. In my opinion the fungus presented here is the same posted by Enrique Rubio (http://www.ascofrance.fr/search_forum/15884), The fungus was found on dead twigs of Tabebuia sp., in Southeast Brazil. Short Description: Stroma dark brick-red to brown, 3 to 8 mm, sometime reaching 1 cm, with minute whitish dots (ostioles) below or at same level of the stromatal surface (Fig.1A-D); Ectal-excipulum textura prismatica (Fig.1H); Asci cylindrical up to 130 x 6-8 microns (Fig.1I-K); Ascopores periospores (Fig.1L-O) elliptical with on side flattened, 8.5-10 x 4-5 microns, with germ slit from end to end (Fig.1Q-S) and with almost inconspicous ring-like transverse ornamentation (Fig.1T). Additional notes: This specimen reacted positively with MLZ (blue apical ring), without pre-treatment with KOH (Fig.1P). Orange pigments on paper with KOH 5% (Figs. 1E-F). Any advise will be welcome. Thank you very much. Legend: A and B - superficial view of the stroma; C - transversal section of a stroma; D - laminar section of a stroma; E, F and G - pigments on KOH after 10 sec, 5 min, and 1:30 h, respectively; H - ectal-excipulum textura prismatica; I and J - asci on MLZ; K - young ascus on H2O; L, M, N and O - sheat release; P - blue apical ring in MLZ without pre-treatment with KOH; Q, R and S - germ slit; T - ring-like transverse ornamentation.. Bars=10 microns, except A-G.

Hyaloscypha herbarum?

Hello, I have here an ascomycete collected in Moravia, in elevation 220 m a.s.l., on strongly decayed stem of a broad-leaved tree (dominant species in the place are Populus tremula, Betula pendula and Alnus glutinosa). Ascospores hyaline, sometimes septate, (7.6) 9.7 - 12.1 (13.7) × (2.4) 2.7 - 3.1 (3.4) µm Q = (2.5) 3.2 - 4.3 (5.4, Me = 10.7 × 2.9 µm; Qe = 3.7 Asci without croziers, IKI+, MLZ+, (49.3) 53.5 - 64.3 (73.7) × (7.1) 7.7 - 8.5 (8.9) µm Q = (6.3) 6.33 - 8.4 (9.5), Me = 59 × 8.1 µm; Qe = 7.3. Hairs are smooth. Using Seppo Huhtinen´s key, I came to Hyaloscypha herbarum, although the asci are longer. Also the pattern of lipid bodies is different than I can see in Enrique Rubio´s photos. Can somebody confirm H. herbarum or suggest a better option? Thank you, Zuzana

Calycellina spiraeae spores

<div>Bonjour tous</div> <div>While processing images of this delightful little fungus I noticed that some of the ascospores show a distinct hyaline "sheath". I dismissed the possibility that it was an artefact, largely because it does not show on all the spores photographed in exactly the same way. As you can see it is also evident in the spore seen "end on". </div> <div>I can easily see that this might be missed by normal light microscopy but wondered whether any other members have noticed this phenomenon?</div> <div>Cordialement, Chris</div>

Plectania milleri 130422

Buenos días El otro día me trajeron estas Plectania de 4-6 x 1-1,5 cm de un bosque mixto de Pinus y Quercus, separadas entre ellas por unos 100 m, saliendo en zona donde predominaba el Quercus y no había Pinus cerca. El borde es festoneado, el exterior está cubierta por una densa malla de pelos marrones-negruzcos, sobre todo en la base, no tiene látex. El excípulo ectal tiene textura subglobulosa-angularis, de células oscuras, marrones, con numerosos pelos marrones, largos, sinuosos, septados. El excípulo medular tiene textura intricata, de color claro, no se aprecia que sea gelatinoso. En su interior se aprecia de forma dispersa algo parecido a los pelos externos o pequeñas manchas marrones en las hifas, que recuerdan vagamente a los "finger-prints" de Otidea bufonia. No son abundantes como los señalados en "Contribution to the knowledge of Plectania milleri, a Northwestern American species" de Carbone, Agnello y Harnisch, pero sí están presentes. El subhimenio tiene textura intricata, de color claro. Las ascas son muy largas, octospóricas, uniseriadas, IKI -, con la base en zig-zag y en ocasiones bifurcadas, de (344) 370,9 - 458,3 (494) × (10) 11,6 - 14,9 (15,9) µm; N = 27; Me = 418,8 × 13,1 µm. Las paráfisis son de 2 tipos: unas estrechas cilíndricas y ramificadas en el ápice y con forma de cuerno; otras más gruesas, no ramificadas y con paredes más gruesas, en ocasiones más coloreadas, que podríamos llamar "setas". Las esporas son elipsoidales, bastante alargadas, lisas, en ocasiones con una cobertura gelatinosa en los laterales (no se han apreciado en los polos), y con 4 núcleos, de (22,3) 23,4 - 26,8 (29,4) × (9,2) 9,6 - 11,2 (12,1) µm; Q = (2) 2,1 - 2,7 (3,2); N = 61; Me = 25 × 10,5 µm; Qe = 2,4. Con estos datos, viendo el artículo anteriormente citado, sólo llego a Plectania milleri, especie conocida únicamente en Estados Unidos. Aunque hay algunas discrepancias con lo citado en el artículo mencionado (el subhimenio es claro, el excípulo medular no es gelatinoso y no se menciona que las esporas tengan 4 núcleos) quizá se deban al estudio de material seco frente a este nuestro en vivo. Gracias por vuestra opinión. Miguel Á. Ribes

Sobre un tallo herbáceo seco ¿.....?

Hola. Un diminuto ascomiceto a modo de granos negros brotando sobre la superficie de un tallo fino de herbácea seco. Pequeños apotecios sobresaliendo poco por encima de la superficie, con un diámetro de entre 0,4 y 0,8 mm., con un ostiolo en su parte central y en algunos ejemplares con una leve proyección vertical. Ascos octospóricos, sin observarse de manera clara uncínulos en su base, con aparato apical amiloide al Melzer. Paráfisis filamentosas, hialinas con tenue contenido granuloso en su interior y que sobresalen por encima del nivel de los ascos.

It's been hot and dry here

Hi all, if somebody has Mycologia Montenegrina 16 (2013), in the special it is Strobiloscypha cupressina. The entry in database from E. Rubio I have already found. Thanks in advance. Peter.

So I've been forced to seek damp places. The bottoms of drying ditches have been full of wonders. For instance these:

Rubus fruticosus disco

<div>Bonjour tous</div> <div>I have been doing some collecting on Rubus fruticosus (agg.) recently, and this is one of several Helotiales I have encountered.</div> <div>Apothecia subsessile up to 300µm diameter, minutely downy, starting creamy and turning rusty-red, basal cells thick-walled, globose, running into elongated rather glassy hyphae, the terminal excipular cells rather thick-walled and ending in cells with refractive contents as can be seen in the images.</div> <div>Asci 8-spored, in IKI deep blue, I could not see any croziers. Paraphyses often with extensive continuous to interrupted vacuolar contents. Ascospores (7.2)8.1-8.9 x 2.7-3.2µm, guttules as seen in the images. Enrique Rubio commented recently that many spores of Helotiales, when freshly ejected show a sort of "sheath"; in this instance a number of spores showed a sort of "halo" at one end - see image.</div> <div>Associated with this apothecium were a number of two-celled hyaline bodies which appear fungal; these can be seen in the final photograph but also in #2.</div> <div>I was wondering about Pezizellaceae? As ever, any comments would be appreciated.</div> <div>Amitiés</div> Chris

Thelebolus?

J'en appelle à René... Très petit, invisible à l'oeil nu, sur pelote de réjection, en compagnie d'Ascobolus brassicae. Asques operculés, j - , à 16 spores, de 10-12 x 7-7,5 Les spores laissées sur lames perdant l'eau d'observation+lugol, se contractent et forment une guttule huileuse. Je continue à chercher, mais les thelobolus sur excréments n'ont pas ces spores-là... S'il s'agit bien d'un Thelebolus. Merci d'avance jean pierre

Dothideomycete

Bonjour, Je vous ajoute quelques photos d'un dothideomycete (comme m'a dit le camarade Enrique Rubio), que j'ai trouvé le 5 décembre près de l'étang du Banyoles sur bois morte de possible Salix. Les pseudotecia? qui sont tuberculées mesurent 160 ?m aprox. J'ai pu regarder les spores, qui mesurent 14,4 x 4,8 micres. J'espère que vous pouvez m'aider à déterminer de quelle espèce il s'agit.

truffe

Bonjour à tous, Un voisin m'a apporté une "truffe jaune " de son jardin sous pommier. Odeur faible agréable indéfinissable (demi exemplaire un peu séché.) taille 2,5 X 1,5 X 1,5 cm à bosses très arrondies extériur ocre jaune. Peridium lisse épaisseur 0;2-0,3 mm blanc très distinct de la gléba elle même couleur liège à brun-moyen. "fils" blanchâtres 0,5 mm un peu rayonnants. Peu de crevasses ou failles. Asques vides en poches transparentes subsphériques 100 X 65 µm 1,2,3 ou 4 sporiques Moyenne 3 Spores brunes elliptiques réticulées en nid d'abeille Réticule hexagonal 4 à 8 µm hauteur 5 µm Taille hors tout des spores: (1) 65 X 45 µm (2) 50 X 40 (3) 45 X 35 µm (4) 40 X 30 µm retrancher 10 µm environ pour mesures sans réticule Je n'ai que la clé de Nordic ascomycetes et trouve Tuber rapiodorum plutôt que borchii Spores plus elliptiques moyenne du nombre de spores dans l'asque 3 au lieu de 1,5 et peridium bien distinct de la gléba. Remarques: sur le Net rapiodorum semble plus connu sous le nom de rapaeodorum rapaeodorum = puberulum ( Riousset ? ) En 2005 Trappe a fait des séquences ADN de truffes blanches :foetidum, maculatum, borchii, puberulum et rapaeodorum et semble affirmer que ce sont tous de bonnes espèces. (magnatum ???). Pouvez vous m'aider dans ce domaine mal connu dans les Ardennes ? Je n'ai pas la clé de Riousset 2001 Merci d'avance. Robert

Chaetosphaeria?

Hola. Un Piremomyceto recogido este pasado domingo brotando de manara masiva sobre la superficie de un tronco cerca de un riachuelo y al lado de un bosque de pinos. Peritecios negros, globosos, de pared gruesa, con superficie delicadamente verrucosa y una discreta protuberancia en su parte superior. De pequeño tamaño, con un diámetro de entre 0,15 a 0,27 mm. Ascos octospóricos, sin aparente reacción de su diminuto aparato apical ni al IKI y tampoco al Melzer. Paráfisis filiformes e hilainas, inamiloides al Melzer que sobresalen poco por encima del nivel de los ascos. Ascosporas fusiformes, algunas discretamente alantoides, de las que se producen y se desprenden de sus extremos unas pequeñas microsporas. Las ascosporas obtenidas por esporulación natural y en agua con unas medidas de: (17.4) 18.3 - 23.4 (24.6) × (3.2) 3.3 - 4.5 (5.5) µm Q = (4.1) 4.8 - 6.1 (6.9) ; N = 30 Me = 20.7 × 3.9 µm ; Qe = 5.4 Las microsporas con unas medidas de: (4.4) 4.8 - 5.4 (5.8) × (1.4) 1.6 - 1.9 (2.1) µm Q = (2.5) 2.7 - 3.1 (3.8) ; N = 30 Me = 5.1 × 1.7 µm ; Qe = 2.9 Consultando el trabajo de Baral, lo más parecido por sus características sería una Chaetosphaeriaceae. Lo curioso es que estudios parecidos a este ya habían salido por aquí antes, dejo un par de enlaces: http://www.ascofrance.com/forum/52590/chaetosphaeria http://www.ascofrance.fr/forum/29110/chaetosphaeria-sp A día de hoy el primero sigue sin respuesta y con el segundo se baraja la posibilidad de que se trate de Chaetosphaeria pulviscula, pero he consultado los trabajos de Reblova y aunque siguiendo sus Claves me conducen a la Chaetosphaeria pulviscula, Reblova no menciona en su trabajo estas microsporas tan abundantes en mis muestras. Cualquier oponión por vuestra parte será bien recibida. Muchas gracias de antemano. Saludos cordiales.

Preussia/Sporormiella on grouse dung

I made an abundant collection of some Preussia/Sporormiella on dung of hazel grouze (Tetrastes bonasia) in western Finland. It is somewhere in the neighbourhood of leporina - subtilis but I have difficulties in finding a good match. The spores are (26.7) 27.8 - 34.9 (36.9) × (4.8) 5.0 - 6.3 (6.8) µm, soon breaking up into four part spores. The asci are (108.7) 120.4 - 151.5 (184.7) × (10.1) 11.6 - 14.2 (14.6) µm. Other details in the photos. Ideas, anybody? ------ Update: I was wrong about the substrate - it is black grouse (Tetrao/Lyrurus tetrix).

Anthracobia, avec doutes

En zona arenosa incendiada hace año y medio, sobre arena pura o rodeados de musgos varios. Apotecios de hasta 8 mms de diámetro, de coloración que veis. Ascas cilíndricas, no amiloides, operculadas, octospóricas, monoseriadas. Ascosporas elípticas, lisa hialinas, la mayoría bigutuladas de 15-17´5 x 9-10 micras. Parafísis con contenido anaranjado, medidas hasta 175 x 11(en ápice) micras. Aquí es donde viene mis dudas pues las estructuras que os mando se diferencian de las parafisis y para ser pelos son hialinos, septados y sin ensanchamiento en ápice llegando a medir más de 200 micras. Pensando en Anthracobia maurilabra, pero no lo tengo claro. A ver que os parece.

Amphisphaeria?

Hello, I have collected several times a pyrenomycete that keeps me busy. All the collections were made on Phragmites culms. Perithecia immersed, erumpent. Asci cylindrical 157-179 x 10-11 µm, with a well developed apical pore, amyloid in IKI. Spores 1-septate, dark greenish brown, with a long germ slit in each cell, without gelatinous caps or appendices (no China ink tested), 17-23.5 x 7.5-8.5 µm. I think it must belong to Amphisphaeriaceae due to its 2-celled pigmented spores and asci with amyloid apparatus, but I fail to find any species with similar spores in the family, especially with those germ slits (which I would say are more typical in Xylariaceae). I compared it first with Cainia griminis, but it has longer spores with several germ-slits at the end of the spores. It keys out in Amphisphaeria according to Barr, but I do not find any species with similar spores in the genus. Any hint? Anything I might have missed? Thank you in advance! Ibai.

Cistella on Juncus

<div>These very small (the yellow stuff is pollen) Cistellas were growing on a dead stem of Juncus sp.</div> <div>There were some budding things (conidia?) In all the preparations I made. Not sure if this is from the Cistella, or some contamination. The spores measure 8.2 - 10.1 × 1.9 - 2.1 µm, asci without croziers.</div> <div>The spores are pretty narrow, but otherwise the folder "Cistella subfugiens" would seem to be similar to this.</div>

Des ascomes noirs globuleux, de diamètre 300µm environ, paroi de 35-40µm, immergés sous l'épiderme du Ruscus, llaissant apparaître un ostiole en surface plutôt cylindrique que compressé latéralement, à peine une petite fente visible. Asques bituniqués, cylindriques rétrécis à la base, de 100-120 x 12-14µm. Ascospores obliquement unisériées, brunes, trois cloisons transversales, 0, 1 ou 2 longitudinales, de 14-19 x 5.3-6µm, à extrémités assez arrondies. Après avoir un temps pensé à Thyridaria rubronotata, je me suis tourné vers les Lophiostoma. J'avais pensé d'emblée à L. quadrinucleatum var triseptatum (nom peu original, convenons-en), mais mes spores sont trop petites. Je suis coincé. J'ai éliminé les espèces affines à compressum, de par l'aspect macroscopique. Merci si vous pouvez me décoincer. Alain

Ayuda con Iodophanus sp

Hola a todos/as Adjunto fotos de unos supuestos Iodophanus, recolectados en el norte de España, crecían en el suelo, entre el césped (Gramíneas) de una piscina cerca de setos de cipreses (Cupressus sp), muy probablemente relacionado con excrementos y orines de pequeños roedores, topillos (Microtus arvalis) Ascomas de hasta 1,8mm de diámetro. Esporas elipsoidales, con núcleo central, presenta una ornamentación muy difusa y difícil de observar, adjunto varias fotos en varios tipos de montaje a ver que pensáis? Yo creo que no están ornamentadas y son lisas. De: 15,2 [16,2 ; 16,6] 17,6 × 11,8 [12,3 ; 12,5] 13,0 µm. Ascas con 8 esporas, de paredes amiloides en IKI y base pleurorrincas?. Paráfisis con septos, bifurcadas cerca de la base y pigmentos carotenoides de color naranja. Excípulo ectal de textura globosa/angularis y E. medular intrincada. A ver qué pensáis, a mí no me cuadra con ninguno de los Iodophanus consultados. Gracias anticipadas y saludos a todos. Curro Valencia

¿Paratrichophaea boudieri?

Hola a todos. He cogido unos hongos que pienso que puede ser Paratrichophaea boudieri, pero me hacen dudar las esporas multigutuladas y tampoco he leído nada sobre el contenido de las paráfisis. ¿Que os parece? Apotecios hasta de 6 mm, creciendo de marera gregaria sobre pequeñas ramas y acículas en descomposición de Pinus halepensis, cupuliformes, con el himenio liso, blancuzco y el margen y exterior cubiertos de pelos marrones. Pelos hasta de 850 µm de longitud, generalmente acuminados, multiseptados, marrones, de paredes gruesas, en algunos casos de base bulbosa. Escípulo ectal compuesto por células hialinas de textura gobulosa o gobuloso-angular. Escípulo medular compuesto por células alargadas, hialinas, de textura intrincada. Ascas de (270-)290-325(-330) × (11,5-)13, 5-18,5(19) µm, cilíndricas, estrechándose en la base, octospóricas, operculadas, no amiloides, con crociers en la base. Ascósporas de (18-)19-22,5(-23,5) × (8-)8,5-10(-11) µm, Q = (1,8-)2-2,4(-2,7), N = 90, Me = 20,9 × 9,3 µm, Qe = 2,2, de estrecha a largamente elipsoidales, lisas hialinas, multigutuladas en su interior. Paráfisis cilíndricas , septadas, multigutuladas en su interior, con el ápice poco o nada engrosado de (2,8) 3,1 - 4,3 (5) µm de anchura. Saludos. Salvador.

Capitotricha

Hola a todos. Hace unos días encontré estos hongos creciendo sobre Pterospartum tridentatum. Yo creo que es Capitotricha, aunque no me encaja con ninguna. Me gustaría conocer su opinión. Gracias. Apotecios creciendo en tallos muertos de Pterospartum tridentatum, hasta de 1 mm, cupuliformes, ligeramente estipitados, con el exterior y margen cubierto de pelos blancos, e himenio amarillo-anaranjado. Pelos hialinos, septados, cubiertos de pequeños gránulos, y a veces con algunos cristales en los ápices. Ascas de 85,57 - 98,55 x 11,33 - 13,47 µm, octospóricas, con el poro apical amiloide y croziers en la base. Ascosporas de (16,60) 18,62 - 25,10 (27,10) x (3,93) 4,10 - 5,24 (5,41) µm; Me = 21,45 x 4,82 µm ; Qe = 4,47, irregularmente biseriadas, hialinas, con 3-6 septos transversales, ligeramente constreñidas en los septos. Paráfisis lanceoladas, septadas, con pequeñas gotas de pigmento amarillo-anaranjado en su interior. Saludos. Salvador.

Helicogonium et un anamorphe

Salut, je suis ces jours en vacances de navidad et cherche un Mollisia qui est pour moi un vieux problème; j'ai trouvé de nouveau Helicogonium et à son côté un anamorfo. Et je me demande si celui-ci peut être anamorfo d'Helicogonium puisque je ne sais(puisque je connais aucun). amitiés Carlos

Hymenoscyphus s.s. on various herbaceous stems

• Macro and habitat suggest Hymenoscyphus s.l., confirmed by micro. • Spores and excipulum suggest H. s.s., but the apothecia have a more grey colour than I have seen before. • It looks similar to H. fucatus but the spores are slightly shorter on average. • Otherwise, there are similarities with H. scutuloides but the spores are wider, or H. aff. vitigenus but the LBs in the spores seem different. Habitat: On dead stems of various herbaceous plants, including Urtica dioica and possibly Bromus slyvaticus and Rubus fruticosus agg., on the ground, wet when found and ground muddy, generally shady and damp area, on the side of a low bank, separated from a small river by a path, flooding in very wet weather, after rain, Salix nearby, mixed deciduous woodland, Low Weald, southern England, late-October. Apothecia: Many thousands, even hundreds on some stems, < ~1 x 2 mm, gregarious to 3-4+ caespitose, whitish when immature but soon becoming reddish-grey colour, darker with age, cupulate to discoid, disc apparently soon becoming plano-concave, sub-stipitate to stipitate. Low magnification: Receptacle more brownish, disc whitish and slightly pruinose, margin relatively indistinct but often slightly darker, undulating more in larger apothecia, stipe like receptacle but often slightly more translucent, obconical to narrow-cylindrical, two appear fused at the stipe, . Asci: Cylindrical-clavate, with croziers, rings bb, Hymenoscyphus type. Spores: Ellipsoid-fusoid to slightly clavate, mostly heteropolar, then with the apex more rounded and the base more acute, slightly curved or asymmetric in profile view, and often slightly scutuloid and slightly restricted in the centre, 2-4 large LBs and many smaller ones, possibly some very short setulae seen occasionally, apparently uninucleate when mature, but becoming uniseptate outside the ascus and more oblong to distinctly clavate, some with brownish walls, two septate spores seen germinating from the side close to the hook and septa or the basal end. - Apothecia 1, free spores or stuck to the receptacle, many septate, in water: (20.1) 20.2 - 23.0 (23.7) × (5.0) 5.4 - 6.6 µm, Q = (3.2) 3.3 - 4.1 (4.5), N = 24, mean = 21.7 × 5.9 µm, Q mean = 3.7. - Apothecia 2, discharged from asci, aseptate, in water: (20.1) 20.6 - 25.0 (25.4) × (4.8) 5.0 - 6.0 (6.5) µm, Q = (3.2) 3.8 - 4.8 (5.2), N = 20, mean = 23.2 × 5.5 µm, Q mean = 4.3. Paraphyses: Narrow-cylindrical, apex with Hymenoscyphus type VBs, VBs relatively large and sometimes hard to resolve or coalescing quickly. Structure of the excipulum seems comparable to other species in Hymenoscyphus s.s., but lots of organish-brown exudate in the ectal excipulum, inside the stipe, and around the external network of hyphae.

Chris Yeates

I am letting you know that our good friend and colleague Chris Yeates had a heart attack yesterday and unfortunately the medical team were unable to resuscitate him. This as you can imagine came as a huge shock as I was meeting him tomorrow as he had been assisting in the arrangements for the BMS autumn meeting in East Ayton, Yorkshire, UK. The only consolation is that he was looking forward to the meeting and so passed away anticipating what he enjoyed the most. Chris had remarkable recall for nearly everything – fungi, birds, plants, tv comedy scripts, Captain Beefheart lyrics ... A great friend and a great loss. Chris had been to the doctors a couple of weeks ago and had complained of spells of dizziness which he had put down to the colder weather and his asthma. The 51 participants in scarborough will try to ensure that we work hard this next week to increase the Yorkshire sp list. This was his life passion, his aim and he was well on with this project. I'm sorry to have to pass on this very sad news to you. Carol Hobart

in other words

<div>Hello forum,</div> <div>this is a tentative translation in English of Michel's words.</div> I speak on behalf of his closest friends to inform you of the sudden death, at his home, of Christian Lechat. Yes, our friend Christian ! The creator of this magnificent Ascofrance forum which has become, as he wished, an essential link between the members of the mycological community passionate about the study of ascomycetes. A community without borders, animated by the sharing of knowledge as much as by mutual respect. Christian leaves us at the top of his art in the study of Hypocreales, especially Nectriaceae and Bionectriaceae, a field in which he handed on to us dozens of new species, many of which were collected in the Lesser Antilles and French Guiana. Christian was soon to celebrate his 70th birthday, he had many publications in progress and devoted himself entirely to this immeasurable task, most often with Jacques Fournier and Amy Rosman, among other faithful and numerous friends. His expertise, recognized by the international community, earned him the Gordon and Tina Wasson Award from the prestigious Mycological Society of America in 2020. Christian was also an actor at the local level where he chaired for nearly twenty years the Mycological Society of the Massif d'Argenson within which we organized together the fabulous meetings of Mellasco. Ascofrance must remain this place of meetings, sharing and friendship that Christian created. We will see to it. Michel

A pyrenopeziza-like disco on Agropyron

Bonsoir à tous, I am looking for some help for this newly collected fungus on dead stems of Agropyron acutum : Asci IKI blue and H+ . 75-87 x 9,5-11. PS 40 µm Spores 32-35 x 2,5-2,8, with rather large guttules . No septum observed. Paraphyses whithout homogenous vacuoles but with round few refringent guttules staining in CRB. Margin ''hairs'' up to 45 x 5 1-3 x septate, The paraphyses content excludes Mollisia I think though there is a Plate by ENrique in Zotto's Mollisia pilosa file with rather similar spores. M. pilosa has other characteristics anyway. I believe this collection belongs in Pyrenopeziza but there is no Pyrenopeziza species I can find in Litterature matching it. Many thanks . Amitiés.

Trichophaea? on plant debris

Hi, I did not manage to determine these hairy cups with Nordic Macromycetes. Maybe someone here is familiar with the species. They are 3-6 mm wide. Spores are about 18-22x9-10+. Asci are about 200-260x12-18 and paraphyses exceed asci a bit and are septate, 5-8 wide. The hairs are brown, septate, up to about 400x8. Marja

Miladina lecithina-spore content

Hello, in this ascomycete everything seems to fit well to be Miladina lecithina, but the spores aren´t filled by many small guttules, there are usually 2 big guttules (or 1 guttule from 2 fused ones). Is it OK? Apothecia 0,5-3 mm wide, orange, sessile, plane, rounded, without hairs, with a distinct margin. Spores 19,5-22,5 x 10,5-12 micrometers, ellipsoid, with small warts, hyaline. Asci 210-280 x 17-22 micrometers, cylindric, containing 8 spores in 1 row, not blue in Lugol. Paraphyses 2,5-3 micrometers broad, apex broadened up to 7,5 micrometers, septate. On wet wood in a small brook, Georgia, 25/6/2014. Zuzana

"Eutypoid fungus on Rosa

Hi there, I have found an eutypoid pyrenomycete on dead stems of Rosa. It has spores around 7-9x1,5-2µm and longstalked, 8spored asci 85-110x5-8µm. The Ostioles do not have any "ornamentation", as seen in many Eutypa-specimen. There is also a very thick perithecial wall. Ok I think it is Cryptosphaeria lignyota...or not? Well watch the photos, and perhaps you can help me :) many thanks and regards björn

Lachnellula on Larix

Hello everyone.. I am finding a discomycete on small dead twigs of Larix laricina that have been broken off during a February windstorm here in coastal New Brunswick. It appears to be close to Lachnellula occidentalis (Hahn & Ayers) Seaver but the hymenium is not orange-buff to salmon orange as described by Hahn & Ayers, Seaver and other authors, and the apothecia are smaller. The ascospores measure 16.3-20.8 X 5.6-7.1 µm, which is close to the original description. So far I have not seen a description of IKI or Melzers reactions in L. occidentalis. The description L. occidentalis in Nordic Macromycetes seems to differ from that of Hahn & Ayers in giving the ascospores as 18-20 X 7-9 µm and the paraphyses as monilioid. Perhaps it is not the same species. Other species that might fit my material are L. hahniana (Seaver) Dennis, L. oblonospora Hahn & Ayers and L. calycina (Schumach.:Fr.) Sacc. in the sense of Fungi Rhen. 1206 as examined by Hahn & Ayers in their 1934 paper. Can anyone offer some guidance here? Dave?

Xylariaceous? with both-sided germ pore

Hello everybody, Any help with this one would be most welcome: Substrate: Fagus sylvatica deadwood trunk Macro: Perithecia 0.4-0.6 mm in diameter, black but covered with rust-colored granules. Perithecia singly at the very margin, but soon very densely packed and coalescing thus looking like a Hypoxylon species. Fruitbody yields a reddish brown KOH extract. Micro: Asci cylindric, inamyloid, 85-103 x 5-6 µm. Spores aseptate, narrowly elliptic, equilateral, brown, smooth, with germ pore on either side, no germ slit observed, 13-16 x 4-5 µm. Perithecial wall composed of very dark colored round to angular, thick-walled cells. Many thanks and best wishes, Stefan

roseodiscus sp?

Hi! Found this one in sweden some days ago. that that it would be R. formosum but asci react blue not red in Lugols. Spores 10-11 x 3-3,5 um with some olidrops. some spores twocelled. Some sporeends react red with lugols as in formosum, maybe all but hard see. I see on the web its a collection from spain that have blue reactions on asci. maybe same or is it a variation on formosum? host moss is Ceratodon purpureus. anyone knows moore about it? regards

Chloroscypha seaveri ? on Thuja leaves - Denmark V. 2019

I have encountered scanty materiale of a tiny (!) discomycete on decaying Thuja leaves in the company of Pestaloptis (fc.) funerea and an indet. thyriotheciod/apiosporous ascomycote (https://svampe.databasen.org/observations/10013764). The discomycete is macroscopicaly blackish and short stipitate but dark olive in water. The spores tend to have an acute apendix. Tjhe Petrini key leads to C. seaveri.

Trichobolus zukalii

Found on dear dung. First a circular fruitbody with lots of hairs and in a later stage a transparent bulb probably containing one or more circular asci. Setae: thick walled 2.3-3.2 um, septated (5-septa mostly) 208-356x7.41-8.52 um, pointed and rounded tops. No paraphyses observed. Spores: 9.97-10.85x7.94-8.46 um. When mature the outer layer of the fruitbody separates from the inner structure still holding setae and the transparent bulb appears. Radius of the bulb is 0.56 mm. Looking at the sizes of the spores and the shape of the fruitbody there is no match in my view with T. Zukalii or T Sphaerospores. Microscopical information for both fruitbodies shown is identical only the sizes for the spores is somewhat smaller because they are still inmature.

Melastiza boudieri

Bonjour, aujourd'hui nous avon eu la bon chance de trouver Melastiza boudieri. Le fiche dans AscoFrance nous a aidé beaucoup :-) Mais néanmois j'ai la question, qu'est la difference entre M. boudieri et M. flavorubens - sauf la couleur. Notre collection etait rouge, plus rouge que des Scutellinias, presque comme Parascutellinia carneosanguinea. Donc nous avons Le nomme Melastiza boudieri. Je vais essayer de faire des fotos micro et le presenter plus tard. Mais pour le moment je voudrais aussi bien savoir, ou des collections de cet espèce sont presenté, publié etc. JÄai Häffner 1986, mais je n'ai pas Schweizer Zeitschrift für Pilzkunde 1991 (Auteur?). amicalement, Andreas

un autre diaporthe,

Bonjour à tous Moi aussi je galère avec un autre diaporthe, et je ne manquerai pas de faire un clin d'oeil à Enrique ;) Le mien a de grandes spores 19-23 x 4-5 µm, trop grandes pour le peu d'espèces que je connais dans le genre à tel point que je me demande si j'ai bien affaire à un diaporthe. Et pourtant, j'ai des périthèces immergés plus ou moins rapprochés qui laissent émerger des ostioles proéminents convergents, une allure de diaporthe. J'ai pu observer le stade conidien (Phomopsis) : des conidies de 15x3 µm en moyenne. Le légataire me dit que le substrat est, à seuil de 90% de confiance, de l'ulmus (les 10% étant pour Viburnum) Je vous joins un montage pour la macro, un pour asques et spores et un pour les conidies. En attendant le secours d'un "Diaporthman"... Alain

Paratrichophaea parvispora??

Hola amigos... Adjunto fotos de unas supuestas Paratrichophaea, recolectadas en los márgenes de un río con Salix alba y Populus sp , en el suelo húmedo que deja las aguas al descender su caudal, en el Sur de España. Ascomas muy pequeños, hasta 1,5mm de diámetro, gregarios, de color gris, con el margen y el excípulo recubierto de pelos de color marrón. Ascosporas anchamente elipsoidales, ligeramente amarillenta, en CB presenta supuestamente una ornamentación muy débil y difícil de observar a modo de pequeñas granulaciones. De: 17,4 [18,2 ; 18,6] 19,4 × 11,6 [11,9 ; 12,0] 12,3 µm Q = 1,5 [1,52 ; 1,55] 1,6 ; N = 30 ; C = 68% Me = 18,4 × 12,0 µm ; Qe = 1,5 Ascos octospóricos, con croziers y no amiloides. Paráfisis ligueramente ensanchada en el ápice, con septos, con pigmentos amarillentos en lo alto. Ápice de: 1,8 - 2,2 µm. Pelos del margen de color marrón, con pocos septos, de paredes gruesas, con los ápices acuminados o con formas más redondeadas, con la base simple. Aparte de estos pelos, todo margen está rodeado en su totalidad de pelos más cortos hialinos y clavados. De: 278,4 - 478,1 X 12,8 - 14,3 µm Pelos de la parte externa de apariencia similar a los anteriores y más cortos. De hasta: 229,3 µm Excípulo medular de textura intrincada y excípulo ectal de textura angularis con las paredes de las celulas pigmentadas de amarillo. Células de: 12,2 - 36,1 × 10,1 - 26,6 µm Consultando la excelente ficha de Enrique Rubio sobre Paratrichophaea parvispora, veo que tiene mucha similitud con esta especie, solo el tamaño de los apotecios y el tamaño esporal es algo diferente, de: (16.2-) 16.9 (17.7) x (10.4-)11.5(-12.2) en la de Enrique, en las mías: 17,4 [18,2 ; 18,6] 19,4 × 11,6 [11,9 ; 12,0] 12,3 µm. Tampoco hace mención en su ficha de las pequeñas verrugas que presentan las esporas de mi recolecta. Tengo mis dudas si realmente se trata de esta especie y me gustaría contar con vuestra opinión a ver que pensáis. Gracias anticipadas y saludos a todos Curro Valencia

Pyrenopeziza ''longipilosa''

Bonjour à tous, Has someone already met this Pyrenopeziza with unusually long hairs ? These apothecia were on a previous year's stem of Cirsium palustre , among Pyrenopeziza carduorum, P. atrata and Unguicullela incarnatina (the tiny white thing scattered among). Hairs up to 100 µm and 8 septa assembled into strands at margin Ascus 40-50 x 5-6 µm, H+, IKI-, PS 20-22; spores 8-10 x 1,8-2 , OCI 0,5 Paraphysis x1,5-2,2. EE T globulosa , wall dark, diam. 8-12 µm. Could it be a singular form of atrata as the other characters would fit ? I also wonder whether someone has already sent such fungus but I can't trace it (ENrique ?) and feel sorry about it if it is the case. Merci pour vos avis Amitiés. Michel

Sobre Genista pseudopilosa

Hola a todos. Tengo unos hongos que recogí el año pasado en el mes de Junio. Tiene ascomas globosos de unas 350 µm de diámetro, con un ostiolo de más de 300 µm de longitud, creciendo sobre pequeños tallos muertos de Genista pseudopilosa a 1500 m de altitud. Las ascas pienso que son bitunicadas, con 8 esporas marrones de (24) 25,3 - 31,9 (33,8) × (6,2) 6,7 - 8 (8,4) µm, que se estrechan en los extremos y cuando están maduras tienen 5-7 septos transversales y 0-4 longitudinales en las células centrales, generalmente curvadas, con un apéndice hialino en cada extremo y una fina placa hialina en el lado cóncavo. No sé qué puede ser ¿Alguien me puede ayudar? Gracias. Salvador.

Mollisia ID

Hello. Here is a collection of Mollisia made on a dead branch of Quercus, on soil, with Lachnum virgineum and another Mollisia species (not yet studied). A subiculum is present. Apothecia Ø 1-2.5 mm. 5% KOH negative. Ectal excipulum of textura angularis/subglobulosa, with cells 5–18 µm wide, becoming a textura ± prismatica on the flanks (see fig. 2), emerging in pseudo-hairs, up to 42 µm in length. Medullary excipulum of t. intricata, with hyaline hyphae. Asci 100-110 × 7-8 µm, with crozier, pars spor. ~47-52 µm, apical ring IKI+ (bb). Paraphyses with a long refractive VB, Ø 2.5–3.5 µm Ascospores 17–20 (21.5) × 2.8-3 µm, OCI~3, sometimes with a central septum (but not in asci). I didn't find any species that matches with these characters, so any help will be useful.

Unknown species on hardwood

Hello, I found this species on unknown hardwoord. Frb 2/4mm x 1mm. At the inside you can see multiple round holes (diam 0,5x0,3mm). Spores with 2 very small drops. Size 2/3x9/12µm. Any suggestions? regards, Ralph

Geopyxis cf. delectans

Good morning, I was given exsiccate of this nice discomycete - could it be Geopyxis (Kotlabaea) delectans? Most characters agree, only the spores are a bit too small and no fireplace was noticed in the field. A single apotecium about 1,5-2 cm diam., margin raised and a little brownish, no data about the outside in fresh state. Growing on the ground at the edge of a road, basic soil (on serpentinite), warm locality, no fireplace observed. Microphoto here: http://tmp1.vize.name/myko/indet/ex439.jpg Excipulum two-layered, medúlla = t. intricata, ectal = t. angularis, about same thickness (up to 80-100 um). Surface cells sometimes covered with light yellow-brown exudate, surface looks like dotted. (The exudate is far too orange on the microphoto.) Ascus base distinctly forked like in Pulvinula/Geopyxis spp. Paraphyses filiform, straight, 2 um wide, almost not enlarged at the apex, sometimes branched in upper half, with distinct yellow granules inside even in exsiccate. Spores smooth, ellipsoid with obtuse ends to almost cylindric, uninucleate, with a few little guttules when young, mature with granulose yellowish contents, (11.7)12–13.1(13.7) × (6.5)6.6–7.3(7.6) µm, Q = 1,7–1,9 (exs. in water). Eguttulate spores exclude genus Acervus, non-capitate paraphyses and no distinct hairs exclude Pseudaleuria, Boubovia has smaller apo and curved paraphyses. Other Geopyxis spp should have bigger spores, but I saw only G. carbonaria so far. Thank you in advance for your opinion. Viktorie

Octospora (ou près)

Estimados amigos: Este discomycete lo recolecté hace aproximadamente un mes sobre restos de una hoguera, con presencia de briofitos (Funaria?). Tamaño 3-7 mm de diámetro. Esporas bigutuladas y elipsoidales, casi cilíndricas, con una ligera tendencia a reniformes. Las medidas esporales me han dado unos valores de 13,8 [16 ; 16,8] 19 x 6,4 [7,2 ; 7,6] 8,4. Q = 2 [2,2 ; 2,2] 2,4. Me = 16,39 x 7,39 ; Qe = 2,22 Poseen un margen diferenciado que macro y microscópicamente aparece recubierto de algas, con presencia de pelos hifoides sinuosos e hialinos, de paredes gruesas, septados y no muy abundantes, que miden hasta 250-325 x 6-10 micras. Paráfisis septadas y con terminaciones rectas, de hasta 6-8 micras de ancho, con contenido granular verde oscuro en Melzer. Había pensado en Octospora, aunque con estos pelos o hifas? no descarto Neottiella. De todas formas, ninguna de las especies que conozco de ambos géneros me cuadra con mis ejemplares. Agradecería vuestra ayuda. Saludos, Tomás Illescas Estimés amis: Ce discomycete je l'ai récolté à peu près il y a un mois sur une place à feu, avec présence de briophites (Funaria?). 3-7 mms de diamètre. Spores bigutulées et elipsiodales, presque cylindriques, avec une légère tendance à reniformes. Mesures sporales de 13,8 [16; 16,8] 19 x 6,4 [7,2; 7,6] 8,4. Q = 2 [2,2; 2,2] 2,4. Me = 16,39 x 7,39; Qe = 2,22 Possèdent une marge différenciée que macro et microscópicamente apparaît recouvert des algues, avec présence de poils hiphoides sinueux et hyalins, á parois épaisses, cloissonés et non très abondantes qui mesurent jusqu'à 250-325 x 6-10 microns. Paraphyses cylindriques, septées, avec terminaisons de jusqu'à 6-8 microns de largeur, avec un contenu granulaire vert foncé dans Melzer. J’avait pensé à Octospora, bien qu'avec ces poils ou hifas? je n'écarte pas Neottiella. De toutes formes, aucune des espèces que je connais des deux genres ne s'accorde pas avec mes exemplaires. Je remercierait votre aide. Amicalement, Tomás Illescas

Leucoscypha ??

À voir qu'ils vous semblent ces spécimens trouvés aux pieds d'une touffe de pèlerin, dans un talus au bode d'un chemin, dans une pleine zone avec C. ladanifer et P.pinaster. Apotecios, le plus grand d'eux de 12-13 mms, avec une marge velue. Les poils (cheveux) possibles (peut-être hifas) hialinos, septados, avec un gros mur et avec une pointe émoussée, certain je lui suis arrivé à mesurer plus de 800 microns, mais en général jusqu'à 425 x 8 microns. Ascas cylindriques, non amiloides, avec 8 spores monoseriadas (certains(quelques) placées oblícuamente) de 185-230 x 12 ' 5-17 ' 5 microns.Ascosporas elliptiques, hialinas, bigutuladas la majorité, certaine(quelqu'une,quelque chose) avec un grand gútula et les autres avec múltiples des inclusions; une surface avec tu décèdes verrucosidades (ou avec inclusions granuloides, je n'arrive pas à le définir) sans retículo faites remarquer-lui, de 20-24 x 11-13 microns. Parafisis filiformes, septadas et avec des inclusions fines verdâtres. J'ai pensé à Leucoscypha, mais non patavina par port et couleur. Peut-être l'autre, dans les nordiques il(elle) vient seulement L. leucotricha des spores beaucoup plus grandes. À voir que le Commandement vous semble micro dans un autre courrier.

A determinar

Des corps fructifères copuliformes de commencement à étendus par la suite avec la surface himenial une externe très pilaire, d'une couleur une crème un peu plus clair que la zone interne, qui apparaît plate, inégale et dans les exemplaires les plus adultes un peu d'embudada. Sans odeur et un goût déterminant. Un ramassage dans une zone très humide sur des restes végétaux et collée sur un bois (un aliment que de Castanea sativa) dans un bois de Fagus sylvatica, de Castanea sativa et de Corylus une noisette

diaporthe n+1

Bonjour, Visiblement personne ne s'est prononcé sur les deux diaporthes lancés sur le forum par Enrique et moi-même. Pour autant je ne suis pas refroidi, et je vous en repropose un autre aujourd'hui. Périthèces immergés, isolés laissant apparaitre un ostiole en général peu proéminent. Substrat : Acer sp. Les spores de 10.5-14.5 x 3-4 µm ne sont pas celles de D. varians. Elles sont plus constrictées au niveau du sept. 4 guttules à maturité. Pas d'appendice ou de voile noté. Je pensais à D. acerina. Je rencontre en ce moment au moins deux diaporthes par semaine et mes questions reviennent récuremment. J'ai su déterminer hederae, pulla, oncostoma, OK mais les autres.... Existe-t-il des docs qui me permettraient d'y répondre avec un peu plus d'autonomie ? Qui travaille sur les diaporthes de nos jours ? Bonne fin de journée à tous. Alain

Pyréno à spores filiformes

Bonjour, On m'a légué ce pyréno venant sur bois mort. J'ai cherché vainement dans les Pleosporales et les Melanommatales (il me faisait penser à un Ostropella). La fente ostiolaire est courbe ou sigmoïde. La taille de ces ascomes est proche du mm. Les asques bituniqués mesurent 400-500 x 7,5 µm. Les ascospores sont hyalines (jaunâtres ?) de même longueur multiseptées régulièrement. Si cela peut inspirer quelqu'un, ce ne serait pas de refus. Alain
