Madera posiblemente de Quercus<br /><br />A ver si hay alguna sugerencia<br /><br /><br />Joseba

en madera no determinada<br /><br />A mi me parece  Rutstroemia....<br /><br /><br /><br />Saludos<br /><br />Joseba

Bonsoir. Voici un Rutstroemia trouvé sur branches de Bouleau au sol dans une tourbière. Ce qui m'étonne, c'est la forme des spores, cylindriques quasiment jamais incurvées comme je pensais les trouver, peut-être à tort d'ailleurs. La clé que j'ai m'amène à R. firma mais sans conviction toujours à cause de ces spores que je pensais incurvées chez cette espèce. Micro : Asques IKI+ bb, 140-160X8-12 um, boucles présentes. Spores bisériées, cylindriques, 16,9-19,8X5,6-6,5 um avec deux guttules, Q=2,8-3,3 Paraphyses filiformes à apex arrondi, septées, larges de 2-3 um. Qu'en pensez-vous ? Merci par avance. Yannick Mourgues

Jan. 07, 2007, on small dead branches of Alnus and Salix. Up to 8 mm across, mostly 4 to 5 mm.

Hello, everybody! This fungus was collected on plant debris in oakwood. Some microscopic dimensions: Sporesize - 13-17 * 3,8-5,3 um Asci: 100-120*8-9 um Small spores (presumably conidia?) are presented - 3,6*1 um Apical pore blue in IKI Pleace, help to determinate. I'm only beginner in studying discomycetes, so be grateful for any advi&#1089;e! Thank you, Irina

Old photo (23.09.2011) from Hungary, without micro. Any idea?

it was found in putrid branch from Quercus ilex. Ascospores 19,3-23,0*4,4-4,9 ìm, Q=4,4-5,0

Sur Betula, diamètre max 6 mm<br />Rutstroemia firma ??<br />Cordialement

<div>Apothecia on twigs from a deciduous tree (Central Norway), 3-5 mm in diameter, short-stalked. Outside somewhat "scurfy", stalks short, pale, but darker towards the base. No sign of stromatised host tissue. Asci IKI+ (blue in Lugol), 110-120 x 12-13 mcr, spores 16-18 x 4-5 mcr, with two or three guttules plus some smaller. Paraphyses filiform, 1.5-2 mcr broad. Excipulum I guess is textura intricata. I was expecting Rutstroemia, but don't find a match. There doesn't seem to be any sign of dark lines in the host tissue.  Are there some kind of resin in the hymenium?</div> <div>Photos of re-wetted material. All measures in water.</div> <div>Suggestions appreciated. Thanks</div>

Could someone help with this small cup found on a wood pile.<br />Maximum 14mm across. Ascii tips blued by Lugol, spores 20um 3/5 septate some in the hairs on the stem with small bubbles at one or both ends.<br /><br />Thanks <br />Mal<br />

Good evening,<br /><br />I saw this fungus on wood debris. I'm not sure about the wood, there are many trees nearby, mostly oaks, but spruce too, though it doesn't seem a stick from spruce to me.<br /><br />Spores measure +/-: (11.9) 12.2 - 14 (14.2) × (3.7) 4.5 - 5.2 (5.3) µm<br /><br />Photos: https://mushroomobserver.org/442536?q=1Zha6<br /><br /><br />Would you please help me?<br /><br />Thank you<br /><br />Elsa<br />

Found on a small branch of Betula, very humid habitat near a small pond. Size around 7 mm. Naro-Fominsk, 55° 23' N, 36° 44' E.

Bonjours à tous, Dans Breitenbach & Kränzlin il est noté que R. firma pousse sur les branches de chênes, peut-il pousser aussi sur l'enveloppe et à l'intérieur d'un gland pourri ?? Merci, Henri Noguere

• Macro and habitat suggest Rutstroemia, and possibly R. firma.<br />• Seems to be confirmed by spores etc.<br /> <p>Habitat: On a short twig, looks like Quercus, apparently on the ground (not observed in situ), damp and muddy area, by a large pond, mixed deciduous woodland, Low Weald, England, late-September, after rain.</p> <p>Apothecia: Medium-size Rutstroemia-like, four counted on the twig, loosely grouped, varying stages of maturity, diameter &lt; ~6.5 mm, stipe &lt; ~4 mm (relatively short), orangish-brown, cupulate, receptacle with uneven appearance, covered by a network of darker hyphae, margin distinct, round, bumpy or uneven appearance due to glassy exudate (around marginal hairs), remaining slightly raised above the disc, stipe mostly blackened from the base, covered with short whitish hairs (long hyaline hyphae) under low magnification, disc concave but becoming more plane, shallow, opaque, dull and slightly darker appearance, but lighter and grainy appearance with darker flecks (paraphyses) under low magnification, some localised blackening around the base.</p> <p>Asci: Narrowly cylindrical-clavate, croziers, rings mostly bb but occasionally more dirty rb, form seems typical Rutstroemia, apex rounded-conical when turgid and more acute-truncate when flaccid, more hemispherical when immature, thickening substantial when immature or flacid, obtusely biseriate when turgid, not inverting post discharge, after some time many asci discharging in water mount.</p> <p>Spores: Ellipsoid, homopolar, poles rounded-acute, length varies considerably, usually two large and conspicuous LBs and a smaller one towards each pole (smaller more extreme), and many much smaller ones, free spores occasionally with 1-3 (5?) septa, each cell with a predominant LB (larger towards the centre), some budding from the poles (not seen in asci), ascoconidia &lt; ~ 4 x 3 um with one relatively large LB, budding spores shorter and wider with less or smaller LBs (some moving to ascoconidia).</p> <p>Free spores in water (not budding): (15) 15.8 - 18.9 (19.3) × (4.3) 4.8 - 5.8 (6.0) µm, Q = (2.9) 3.0 - 3.7 (3.9), n = 30, mean = 17.6 × 5.4 µm, Q mean = 3.3.</p> <p>Paraphyses: Cylindrical, width ~ 2.5-3.5 (4) um, multi-septate (some with at least 5), apical cell usually longer (&lt; 3.5x), this with cylindrical VBs, strongly pigmented dirty-yellow, more reddish en masse, apex usually slightly inflated and occasionally irregular, no branching observed close to the apex.</p> <p>Excipulum etc. looks typical for Rutstroemia.</p>

<div>Dear all,</div> <div>This one was sent to me as exciccate. One of the photos is from fresh material.  The rest are from dried material. The apothecia have a hairy stem and are also somewhat hairy along the rim of the apos.  The interior appears gelatinized when re-wetted. Growing on a blackened twig of <em>Corylus avellana</em>.</div> <div>Spores hyaline, ellipsoid, unicellular, measuring 11-13 x 4-5 microns. Two large and many small guttules in water. Two "vaculoes" filling the entire spores in KOH, making them appear 1-septate.  Paraphyses filiform, filled with small "granules" in water, ca. 2 mcr across, not enlarged at the tips.  Asci measuring 90-100 x 8-10 mcr in KOH, slightly larger in water (up to 110 x 12).  Ascus apex IKI+. Excipulum I think should be described as textura intricata or in places perhaps t. oblita.</div> <div>Single spore photo in KOH, IKI+ photo in Lugol, the rest in water.</div> <div>I guess this is a Rutstroemia, but which?  Or am I in the wrong genus?</div>

Previously I've thought that a brown cup like this growing on a branch is R. firma. However, this one's spores seem to be too wide for that species. <br /><br />This was growing on a well-decayed piece of branch of a decidous tree. The place was dominated by Alnus incana, so there's a good chance that is the host. I don't unfortunetely have the sample anymore.<br /><br />R. alni seems to me like a promising candidate. <br /><br />Spore measurements:<br /><br />(16.8) 17.8 - 20.1 (20.2) × (8.1) 8.3 - 8.79 (8.8) µm<br />Q = (2.1) 2.13 - 2.3 (2.4) ; N = 10<br />Me = 18.6 × 8.5 µm ; Qe = 2.2

Dec.05, 2006, our town park. Diameter 5 mm.

Dear Forum,<br /><br />On black remains, probably stromatized tissue, of Juncus effusus, I found some long-stalked apothecia of 5-6mm long.The ectal excipulum consisted of Text prismatica, asci had an amyloid ring, no croziers were found.Spores were hyaline, fusiform and measured 17-18x4µ and contained several large guttules (OCI 4-5).Paraphyses were cylindrical.No sclerotia were found.<br />Could this be R henningsiana?

I recently found this <em>Rutstroemia</em> growing on dead leaves (mainly on the petioles) of <em>Acer campestre</em>. <p>Apothecia are up to 3 mm diameter with a short stalk; the hymenium is pale brown with a darker margin.</p> <p>Excipulum is a textura oblita in part, with thin-walled cells in part.</p> <p>Asci are 85-100 x 10 µm, with tips staining blue in IKI. Spores are single-celled, 12-14 x 4.5-5 µm, with 2 large oil bodies and many minute oil bodies.</p> <p>Paraphyses are 3-4 µm wide, with oil-filled contents in the upper part.</p> <p>The colour of the apothecium and other characters would appear to rule out <em>Rutstroemia (Lanzia) luteovirescens</em>, which is characteristic of <em>Acer</em>. Microscopic characters don't seem to fit well with other species found on decaying tree leaves, so I'm struggling to make an identification.</p> <p>I would be grateful for any help.<br /><br />Marcus</p>

Hello,<br />Looking for opinions on this Rutstroemia; I considered R. alnobetulae - spore size, shape and content match, but there's no IKI blue reaction with paraphyses.<br /><br />Date: 10. 09. 2023.<br />Habitat/substratum: peat bog fragment around a mountain stream, 1800 m elevation, with Alnus, Salix, Pinus mugo, on a dead twig, possibly from Alnus glutinosa.<br /><br />Spore size: Me = 26.5 × 6.2 µm ; Qe = 4.3 (some over 28 µm)<br />Asci: around 170 µm, croziers +<br /><br />Could not make proper section - ascoma was gelatinous and then kind of squishy.<br /><br />Last picture is twig section.

me mandan el material seco recolectado en mdera sin determinar<br /><br />A ver si hay alguna sugerencia<br /><br />Saludos<br /><br />Joseba

Bonjour, voici un Rutstroemia que j'aurais nommé R. firma s'il n'avait pas été sur Alnus glutinosa, mais je vois l'existence de R. alni dans le DVD de Zotto, et j'ai de la peine à voir où sont les différences. Un avis ? Merci d'avance. Patrice TANCHAUD

Dear friends: Last week I have collected this nice purplish ascomata on old indeterminate leaves (Petasites, Ranunculus?) at 1600 m of altitude. Disc up to 0.7 mm in diameter, margin fimbriate, stipe up to 2 mm.

Hello,<br /><br />would anyone have any info about Velenovsky's Rutstroemia quercina? <br /><br />He described it in the Monograph of czech discomycetes. All syntypes and other collections were obviously studied by Dumont in 1972-73 and one selected as lectotype (based on scanned schedae on NYBG website) but did he actually publish it too? I thought Dumont was working towards a monograph of some of the sclerotiniaceous genera, but his series of papers ended when in 1983 he left NYBG never to come back and haven't published in mycology since then. But perhaps I overlooked some useful source? <br /> <br />Thank you for any advices. <br />Viktorie <br />

Hello everyone,<br /><br />some days ago I found a Rutstroemia on Juncus. Thanks to former thread in this forum I was able to exclude Rutstromia calopus (no croziers / substrate). <br /><br />Nevertheless also the German main page for fungi mapping as well as Index Fungorum list R. henningsiana and R. paludosa as individual species. Does anyone know how to separate them from each other? I was looking for literature, but didn't find too much. CASH &amp; DAVIDSON (1961) say that the spores of R. paludosa are 12-14 µm long and the asci around 150 µm. Compared to that, SACCARDO &amp; SYDOW (1902) made an early description and characterized Ciboria henningsiana with spores of 15-18 µm and asci with 160-200 µm length. I'm not sure how to assess these information though. Can anyone help?<br /><br />Kind regards,<br />Jan-Arne

<div>Hello all,</div> <div>Found recently in New York City on the stem of an oak leaf.  There was only one fruiting body so I didn't have much to work with. It appears to be a dark, velvety brown stipitate ascomata with a fringe of light colored hairs at the margin.  </div> <div>Spores are reniform, the bend in the spore in the last 1/3 of its length, 12-14.5 x 5.5-6.3µm. Asci with croziers, about 112 x 13µm, IKI+.  There are a profusion of brown paraphyses which are septate and about 3µm in width.  </div> <div>The spore morphology resembles what i have seen for Rutstroemia sydowiana, but the colors of the apothecium are far more dark than the images I have seen of that taxon.</div> <div>Any help would be appreciated.</div> <div>Ethan</div>

Chers amis, Sur feuilles de Carex, trouvé une douzaine d'ex de ce champignon, 3-4-8mm de diam, avec un stipe qui peut dépasser le diam du chapeau. Base du pied plus foncée, pied duveteux.

Salut ces spécimens recueillis sur le Rhytisma acerinum entre le champignon et la feuille, je pense a priori par le bus de données peut s'adapter Ciboria batschiana l'habitat, mais que la couleur du corps (Ocraceo clair) dévier moi.

Hi, these specimens collected on the Rhytisma acerinum between the fungus and the leaf, I think a priori by the data buses can fit Ciboria batschiana but the habitat as the color of the body (Ocraceo clear) sidetrack me.

Bonjour,<br /><br />récolte réalisée sur le littoral, sur débris de plantes (herbacées ?). Spores 14,5-17 x 6-7 µm.<br />Jusque-là, je nomme de telles récoltes R. calopus (égal ? R. maritima).<br />Merci d'avance pour vos avis éventuels.<br /><br />Patrice T.<br />

<div>Bonjour,</div> <div>récolte réalisée au sol sur un chemin herbeux, ascos greffés sur débris herbacés, aucun sclérote aperçu, apothécies 2-9 mm, spores 13-19 x 7-9,5 µm.</div> <div>Merci d'avance pour vos avis.<br /><br />Patrice</div>

Trouvé hier apré midi , non loin de chez moi en forêt de Virming ( 57 ) en soulevant des branches cassées au sol , de petites fructifications qui poussaient en relation avec de toutes petites branches de hêtre ,couleur brun clair à jaune pâle . Les fructifications vont de 2 à 10 mm en forme de calice ,présence d'un stipe de 2 à 3 voir 5 mm x 1,5 mm. La surface est lisse et l'hyménium et la face externe sont concolores . Asques octosporés , spores uniseriés J + Asque : de 142 - 150 - 155 - 160 x 12 - 14 - 15 µm ascospores elliptiques , lisses, hyalines, non guttulées : 17 - 19 - 20 x 7 - 8 à 9 µm paraphyses filiformes non septées et trés légèrement enflées au sommet jusqu' à 2 µm Au départ je pensais avoir à faire à Rutstroemia firma , mais la micro ne correspond pas , peut être du genre ciboria ?? .Quelqu'un aurait-il une petite idée ?? Merci

<p>I found only three apothecia. First I thought of Ciboria brunneorufa that was shown here shortly before. When I took the microscope I was reminded of Rutstroemia sydowiana - and indeed Quercus ilex-leaves are together with Pistacia (u.a.) in the litter. But the form of the Rutstroemia sydowiana-spores does not fit fully (?).</p> <p>Regards from Lothar</p>

Hello! Found near Argañoso (León) SPAIN, about 1200 meters above sea level, on a birch branch. Apothecium about 4 mm in diameter, fibrillose stipe. Spores measured in water: (19.6) 20.2 - 25.5 (26.3) × (4.7) 4.9 - 6.2 (6.5) µm Q = (3.6) 3.8 - 4.4 (4.5) ; N = 29 Me = 21.9 × 5.4 µm; Qe = 4.1 At first I thought of Rutstroemia but I didn't come up with it. What do you think Greetings and thanks

Hello to all, <p>I send you a Word document with my find on juncus.<br />Is my determination correct? I have my doubts. In Breitenbach(vol. 1 p. 146) it should be stalkless but taking into account the taxonomic corrections the determination is correct! Ellis and Ellis p.498 confirms my conclusion, so am I right or am I wrong.</p> <p>Thanks in advance, kind regards,</p> <p>François Bartholomeeusen</p>

... found near Snasa, 3.7.22, on remains of Poaceae in a small acid marshy rivulet, between Sphagnum. The spores are about 14,5-18/5-5,5 µm large, croziers are present. What irritates me is that the IKI-reaction of the ascus porus is not clearly blue but more greyish-red. Does somebody know about such specimens?<br />Yours, Lothar

Bonjour, cette fois-ci, je sollicite votre aide avec un autre petit ascomycète trouvé sur un chêne (Quercus pyrenaica). Je ne suis pas sûr du genre auquel il appartient. Toute aide est la bienvenue.

Salve! I have found this Rutstroemia on [unidetified] petiole: http://wwkk.mikologia.pl/spec/20051015_001_PERZ/20051015_001_PERZ.php What is strange? Strange is H2O+IKI reaction on..... I do not know where :) It seems to be LB's in paraphyses reaction, or interhymenial gel (A.Gminder) ?? Something is here amyloid! Rutstroemia sydowiana HAS NOT this reaction (H2O+IKI), may be Rutstroemia petiolorum, but i do not have this spec. in my herbarium and i can not test this reaction. What do you think - is this a contaminant in hymenium or this taxon does have amyloid LB's in paraphyses OR interhymenial gel ? Has anyone R.petiolorum and can make test for me? Or may be do you know this spec.? Best, Pimpek

<div>Hello again,</div> <div>A friend of mine found these small cup fungi in a cemetery in NYC last weekend.  They are just under 1cm in diameter and  have quite a long, slender stipe. They appear to be fruiting from the soil.  Another friend provided the microphotos and data.  So this is what I have...</div> <div>Long stipe (3x length of cap), asci up to 150m long.</div> <div>Spores in water <br />11.8 x 5.8µm<br />12.4 x 6.4µm<br />12.7 x 6.5µm<br />13.7 x 6.7µm</div> <div>11-12 x 5-5.5µm (in cotton blue)</div> <div>Ascus tips turn blue in Lugol's</div> <div>Any ideas?</div> <div>Thanks,</div> <div>Ethan</div>

<p>Salut à tous,</p> <p> </p> <p>Yesterday I found many apothecia of this interesting species on fallen leaves of <em>Camellia japonica</em> They measure up to 1.8 mm and had short stalks (up to 1mm). They were present on almost every leaf I inspected.</p> <p>Asci IKI BB, croziers not observed (despite intense searching...)</p> <p>Ascospores 9.8 - 11.9 x 5 - 6 µm, usually with two very large guttules and several smaller ones, with delicate sheaths which quickly disappear in water.</p> <p>Paraphyses with a long, continuous vacuole (as in <em>Mollisia</em>)</p> <p>Flank cells often with brown encrustation, and with large refractive vacuoles which quickly collapse and turn brown.</p> <p>My specimen seems quite close to <em>R.'kalevi'</em> , though the ascospore dimensions are just a little different, as is the guttulation (and substrate). I'll come back later with some photos of  ascus bases.</p> <p>Am I thinking along the right lines? Has anyone collected anything similar on <em>Camellia?</em></p> <p>Amitiés,</p> <p>Nick</p>

<p>Hola a todos.</p> <p>Subo unas fotos de una Rutstroemia que encontramos sobre hojas de Euphorbia en la zona de El Valle del Lago.</p> <p>Esporas de 10,7-12,9 x 4,6-5 micras.</p> <p>Ascas pleurorrincas.</p> <p>¿Qué les parece?</p> <p>Gracias por sus respuestas.</p> <p>Saludos</p> <p>Rubén</p>

Hello Everyone<br />Please could you help me with this small asco found on bare soil with bryophytes and plant remains.<br />Light brown apothecia with darker rim and paler short stipe 0.3-0.4 mm diameter, 0.5 high. Excipulum textura globulosa at the base, textura prismatica at the rim, cells brown 25-30 x 7 microns at the rim.<br />Asci cylindrical with flat apex, J-ve, 160 x 10microns, croziers not seen. Cuboidal crystals amongst the asci.<br />8 spored uniseriate, spores elliptical to fusiform with blunt ends, hyaline, cyanophilous, small guttules clustered at each pole. Some spores septate. 16-19 x 5-6.6 microns.<br />Paraphyses septate and branching, cylindrical, 132 x 5 microns.<br /><br />I have struggled to get to Genus, maybe Graddonia, Mollisia, finally after asking for help and being directed to Zotto's Rutstroemia fulva notes I think it could be around this area.<br />Help please.<br />Pauline

Hola.<br /><br />Este hongo lo recogí en agosto del 2018 en Sierra Nevada (España) a una altura de unos 3060 m, creciendo sobre restos herbáceos sin identificar en una zona encharcada. Los apotecios miden hasta 2 mm de diámetro. El excípulo ectal es de textura globulosa, cambiando a textura prismática o textura porrecta en el pié y textura intrincata en el excípulo medular.<br /><br />Tiene ascas de (123,5) 123,55 - 160,5 × (12,9) 12,93 - 13,58 (13,6) µm, con el poro apical euamiloide de tipo Sclerotinia y la base desprovista de croziers, aunque sí que tienen una protuberancia.<br /><br />Las esporas son elipsoidales, de (15,1) 16,3 - 18,7 (20,2) × (6,1) 6,3 - 7 (7,5) µm, Q = (2,3) 2,4 - 2,8 (3) ; N = 47, Me = 17,4 × 6,7 µm ; Qe = 2,6, con algunas pequeñas gotas de aceite generalmente en los extremos, que al madurar tienen un septo transversal y parece que producen ascoconidios.<br /><br />En principio el hongo me encaja bien con Rutstroemia paludosa, salvo que el excípulo ectal es de textura globulosa como en Ciboria y no textura prismática como en Rutstroemia.<br /><br />Las fotos del excípulo ectal son en vista frontal porque debido al pequeño tamaño de los apotecios no conseguí hacer una buena sección donde se apreciara bien. ¿Podría ser que en sección éste cambiase a textura prismática?<br /><br />Saludos.<br />Salvador.

En talúd muy humedo de riachuelo, sobre las hojas que se ven en la foto, cercano Alnus y Populus, Ø de 2 a 3 mm.<br />Ascas 118-142 / 6-9 , croziers +, IKI +<br />Paráfisis septadas.<br />Saludos

Good evening<br /><br />I have this species from Parador de Mazagon, 15.01.2012 and 12.01.2013, on a small stem, perhaps Ammophila arenaria, 4-6 mm.<br /><br />Spores (1000x, H2O, live)<br />(12.8) 14.0 - 16.8 (17.6) x (5.6) 6.0 - 6.8 (7.1) µm<br />Q = (1.9) 2.1 - 2.7 (2.8) ; N = 82<br />Me = 15.3 x 6.4 µm ; Qe = 2.4<br /><br />I would like to confirm it is Rutstroemia maritima and to know nearest species.<br /><br />Thank you.

Hello, <br /><br />this beautifil species was collected several times at leaves of Rubus chamaemorus. Could be from Rutstroemiaceae, but i have not succeeded in finding necessary description there. Four related species which could be found at this host: Sclerotinia tetraspora, Ciboria latipes, Scleromitrula rubicola, Rutstroemia chamaemori - all have different spores (no mention of allantoid shapes). <br /><br />May be somebody is familiar with this?<br /><br /> Apothecia cupulate, stipitate, 1.3–4.7 mm in diameter, stem 0.8–2 mm high, site densely at both leaf sides, without sclerotia but black stromatized lines are present at the leaf; reddish-brown, hymenial surface minutely speckled, outer surface longitudinally rugose, stem base dark to dark brown. <br /><br />Excipulum from porrecta, outer hyphae incrusted by brown pigment, at the edge not enlarged hyphoid elements; asci with crozies, euamyloid ring, 97.6–125 x 12.5–14; paraphyses cylindrical, enlarged to upper part, rarely branched, septated, with brown content in upper part, about 113 x 4.4 (width at upper part); spores allantoid, with two medium oils and several tiny, 17 (15.4–18.9) x 4.7 (4.1–5) (n=11).

Hello everyone, <p>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.<br />Can somenone give me a clue?</p> <p>Spores: elliptical; filled at the poles with clusters of droplets; Av 16.34x6.50µm (N = 17)</p> <p>Asci: J-; uniseriated, 8-spored</p> <p>Paraphyses: filiform; cilindric; sometimes branched at the top; multiseptated; finely encrusted (?); diameter on average around 3.17 µm</p> <p>Hairs (?) or paraphyses on the edge: thick-walled; multiseptated; finely encrusted; tapered top; content colored.</p> <p>The photo series in the same order with a final image of the outer excipulum.<br />All measurements were done in water.</p> <p>Kind regards, William</p>

L.S.<br />Summarizing the few topics about Rutstroemia maritima here on the Forum and the description of R. calopus in the article "Estudio de la micobiota de los ecosistemas dunares de la Peninsula Ibérica e Islas Baleares"<br />produces the following: <p>R. paludosa - R. calopus - R. maritima<br />Cyperaceae + Juncaceae - Poaceae - Ammophila arenaria<br />long stalk - short stalk - sessile or very short stalk<br />no real croziers - croziers - croziers<br />amyloid - amyloid - non-amyloid</p> <p>and the conclusion that this complex still needs further study.</p> <p>But the last topic is dated 2021 and perhaps new insights have now been emerged?</p> <p>So, once again a Rutstroemia/Clarireedia maritima, R. calopus var or some spec.</p> <p>The substrate consists of the decaying spikelets of Ammophila arenaria, habitat is a small sand drift in the grey dunes.</p> <p>The ascocarps are sessile-short stalked, the color is pale reddish-brown.</p> <p>The asci are non-amyloid and they have croziers.</p> <p>Spores measured (14) 12.0-17.0 x 5.0-7.0 mu, with small droplets.</p> <p>Parafyses cilindric and a bit longer than the asci.</p> <p>I think it should be C. maritima, but does C. maritima now exist?</p> <p>thanks and regards</p> <p>Bertien Roelandse</p>

Bonjour,<br /><br />Je vous soumets cette récolte réalisée récemment sur place à feu sur le littoral. Je n'ai pas vu de sclérote, ni de débris herbacés greffés à la base des stipes. Asques 150-155 x 10-13,5 µm. Spores 15-20 x 6-7,5 µm. Paraphyses filiformes septées. ?Au départ je pensais à R. calopus, mais R. carbonicola serait peut-être un meilleur candidat. Bien qu'étant en possession de l'article de Svrcek (New or less known Discomycetes, 1979), j'ai bien du mal à conclure. <p>Merci d'avance pour vos avis.</p> <p>Patrice T.</p> <p> </p>

Cher amis du Forum: Je vous propose une nouvelle question : Ces ascomata, turbinatées, extérieurement tomentoses, de 1mm d'altitude et 1 mm de largeur, croissent sur les feuilles mortes de Daphne laureola à 1700 m d'altitude. Asques IKI bb, jusqu'à 132 x 11, sans des crochets. Paraphyses avec beaucoup de VBs jaunes - verdâtres. Spores 10.5-16 x 5-8, pleines d'une multitude de guttules refringents. Excipulum médullaire intricata et ectal globulosa. Je pense a Rutstroemia sp. parce que sa base apparaît stromatisée et noirâtre et par ses caractères microscopiques. Avez vous quelque opinion? Dear friends of the Forum: I propose you a new question: this ascomata, turbinate, outside tomentose, of 1mm of height and 1 mm in width, grows on Daphne laureola old leaves at 1700 m.

Bonjour à tout le Forum.<br /><br />Hier, dans le Vallespir, on a récolté sur une chataigne un petit asco.<br />Sur le terrai bien sûr, on a dit <em><strong>Rutstroemia echinophila</strong></em>.<br />Mais "à la maison", je penche plutôt vers <em><strong>Rutstroemia</strong></em> (<em><strong>ciboria</strong></em> il me semble) <em><strong>americana</strong></em>.<br /><br />Pouvez vous m'aider, à la vue des éléments ci-joints ?<br />Et s'il s'agit bien de <em><strong>R.americana</strong></em>, cette espèce est elle courante en France ?<br /><br />Merci à tous, et bonne journée.<br />JL Jalla

Bonjour. J'ai récolté dimanche un petit disco que je placerai volontiers dans le genre Rutstroemia. En voici la description : Sur tige morte de lierre (Hedera), apothécies en forme de gobelet, fixées à la tige par un pseudo-stipe trapu ; disque plan, de couleur brun, marqué d'un petit ombilic ; marge régulière, doite, un peu plus claire que l'hyménium ; surface externe un peu furfuracée, beige sale. Ø 4-8 mm, h=3-5 mm Pas de zone noirâtre distincte au point d'attache. Asques cylindracés, pleurorynques, octosporés, 85-110 x 7-10 µm, à anneau apical IKI + (bb). Paraphyses cylindriques, non élargies au sommet (2,5-3 µm), fourchues à la base, hyalines, cloisonnées. Spores elliptiques, 8,5-10 x 4-5 µm, lisses, hyalines, biguttulées, non cloisonnées et pas de germination visible. Sous-hyménium de textura intricata, à pigment brun. Excipulum ectal de textura intricata avec des éléments ± allongés, parfois renflés, dont certains émergent. Habitat : sous feuillus (charmes, noisetiers, aulnes), près d'un ruisseau. Voilà, je joins un dessin rapide des éléments micros. Si quelqu'un a une idée ?

Le specimen récolté sur du chêne m'a fait penser à Rustroemia firma, mais les spores sont beaucoup plus longues,taille et forme proche de Ascocorynecylichnium; le sommet des asques se colore en bleu avec le Melzer<br />Merci de m'aider

<p>Collected in Portugal, Algarve, nature reserve Fonte Benemola north of Loule, 3.1.2018.</p> <p>Substrate is Arundo donax, as the leaf remains were partly still adhering to the thick lying stems. Unfortunately, most of the collection is badly ripe but I think I could get most of the important characters. Unripe spores in the asci mostly were much smaller (maybe 12-15 µm) than the free ones I measured here.</p> <p>The IKI-reaction of the asci is weak and cannot be seen at all asci. For some time, I was not at all sure to have an inoperculate discomycete - but my pictures clearly show the porus.</p> <p>I think this should be looked for in the Sclerotiniaceae (?) - but I do not have a good idea about the genus and species.</p> <p>Who can help?</p> <p>Best regards from Lothar</p>

Hello,<br /><br />is there any compound that would dissolve the gelatinous substance in inoperculates, e.g. Rutstroemia, Cyathicula, Ascocoryne etc.? Did anyone see it mentioned in literature? <br />Thank you in advance.<br /><br />Viktorie <br />

Hello,<br /><br />I'm looking for any published records of Rutstroemia (Lanzia) longipes from Europe. So far I've only found single records from Hungary (by Svrcek in Czech Mycol.) and Ukraine (on this forum). Would anyone know about other finds please? <br />Thanks a lot in advance. <br /><br />Viktorie <br />

Hello,<br /><br />this looks like Lophodermium petiolicolum, except for the much wider and shorter spores with high lipid contents. Am I in a wrong genus? <br />On Quercus robur petiole and primary vein, soc. Rutstroemia sydowiana. <br />Paraphyses 1,7-2,2 um, with a few scattered small VBs. <br /><br />Thanks a lot for any advise. <br />Viktorie <br />

Dear all,<br />sorry to bother you. Maybe Zotto can help me but I prefer to put this question here! :D <br /><br /><br />I don't remember if Hymenoscyphus aff. epiphyllus growing on Alnus alnobetula sensu Baral (= R. bolaris in Breitenbach &amp; Kraenzlin) has a good (maybe new) name today! <br /><br />I remember to have read something on this subject, but I'm not sure! :( <br /><br />All the best<br /><br />Matte

Hola, he encontrado estas ciborias en unas ramitas de abies alba que estaban cubiertas de Pithya vulgaris,y las he visto en casa al ir a guardar las Pithyas,<br />al ser en Abies pensaba que seria Ciboria rufofusca, pero no lo es la micro no coincide, y en la documentacion que tengo lo mas parecido que en cuentro es Ciboria coryli, que las medidas de esporas entrarian pero las ascas son mas largas en mi muestra, y luego esta el sustrato, ya que no se si puede salir fuiera de Corylus.<br />Apotecios de 1,3--2 mm diametro X 1,4--1,9 mm de altura.<br />Esporas biseriadas, con dos gotas lipidicas, granulos internos, 17--21 x 6--7.<br />Ascas J+, croziers - , 170--205 x 13--15.<br />Parafisis x4 apice x5, septadas, con pigmento marron anaranjado.<br />Alguna idea ???<br />Un saludo<br />Rfaael

Hola a todos<br />Apotecios recolectados en las vainas caídas al suelo del arbusto Spartium junceum, en los márgenes de un camino.<br />Apotecios de hasta 2mm, al principio copulados, después mas aplanados, con el margen muy piloso, de color ocre asalmonado, después gris oscuro.<br />Esporas lisas, con dos o tres gotitas pequeñas en los extremos y vaina gelatinosa.<br />De:<br />(8,98) 10,39 - 12,19 (13,96) × (4,85) 5,05 - 5,76 (6,30) µm<br />Q = (1,42) 1,86 - 2,31 (2,51) ; N = 40<br />Me = 11,38 × 5,39 µm ; Qe = 2,12<br />Ascas octospóricas, amiloides, con croziers basal.<br />De: (102,53) 102,70 - 116,52 (118,01) × (8,75) 9,71 - 11,67 (11,89) µm<br />Paráfisis ensanchada en el ápice, con grandes y largas vacuolas, no refractivas en CRB, curiosamente el ápice reacciona a azul en contacto con IKI.<br />E. medular con multitud de cristales, compuesto de dos capas, una de textura intrincada con pigmento marrón y otra más profunda de hifas paralelas (Porrecta).<br />E. ectal de textura angulosa con algunas células globosas y subglobosas.<br />He pensado en Rutstroemia sp, pero no descarto otros géneros cercanos.<br />Alguna idea??<br />Gracias anticipadas.<br />Saludos<br />Curro

Hi there,<br />yesterday i found on ground this strange asco with stem.<br />The spores are 1-3 spetated and produce conidia.<br />I hope you can help me with the determination.<br /><br />thanks in advance,<br />Thorben<br />

Hello <br />This is me first post on this forum<br />I found this ascomycete on soil nearby a burnplace.<br />I think this is <em>L luteovirescens</em> but i am not sure<br /><br />Is there somebody who can help?

Hello, yesterday evening while looking for those yellow Hymenoscyphus, I stumbled upon more trouble:

Hello dear all,<br /><br />Recently I've found this yellow one on petioles of Fraxinus. I had many other collections this time and didn't explored it in fresh condition:( Nevertheless, maybe you will have ideas about it?<br />I think it is Hymenoscyphus but not sure. Maybe Phaeohelotium?<br />Spores in average (30 spores) 12,9 x 5,5 um, Q=2,35<br />Asci dead, approx. 90 x 12 um, apex of Hymenoscyphus-type (??), blueing in IKI<br />Croziers bad visible, but almost surely present. Paraphyses almost not visible.<br />There are also hairs up to 100 um long, 5-6 um wide, that are a bit confusing (see photo).<br />Thank you in advance,<br />Iryna <br />

I found these small (largest one 3mm wide) ascos growing on thin twigs in a moist, herb-rich forest. Spore measurements: 14-15.5 x 6-7, Q 2.1-2.5. Any idea what these might be?

Hello,<br /> <div>I'm conducting a mycological inventory in two greenhouses in a park in downtown Lyon, one tropical and one temperate. This ascomycetes was found in the second. The substrate is of undefined origin. In the immediate area, there were Camellia japonica and Alpinia caerulea. The spore size is similar to those of Ciboria latipes, which grows on Rubus chamaemorus, although the original description doesn't mention amyloid asci. There are probably other hypotheses, and I'll sequence it, like everything I find in these greenhouses. If you have other hypotheses, they're welcome. Thank you.</div> <div>Spores size :</div> <div>(9,1) 9,7 - 11,8 (13,6) × (4,2) 4,4 - 5,7 (5,8) µm<br />Q = (1,6) 1,9 - 2,3 (2,7) ; N = 41<br />Me = 10,9 × 5,2 µm ; Qe = 2,1</div> <div>Ascis size :</div> <div>(108,0) 108,6 - 115,4 (117,2) × (5,4) 6,1 - 6,85 (6,9) µm<br />Q = (15,8) 16,0 - 18,6 (20,9) ; N = 9<br />Me = 112,5 × 6,4 µm ; Qe = 17,6</div>

• Stromatised substrate and macro like genus Rutstroemia.<br />• Micro seems good for Rutstroemia too.<br />• Quercus petioles, macro, and spores suggest R. sydowiana.<br /><br />Habitat: Stromatised petiole of Quercus robur, well-decayed leaf (but luckily the apex was intact), at the top of damp leaf litter, next to a pond, mixed deciduous woodland, Low Weald, England, early September, after lots of rain.<br /><br />Apothecia: Appears to have been two, light brownish to blackish with yellowish disc, superficial, diameter ~3 mm and height similar, tooth-like groups of marginal hairs with exudate, concolourous with disc, disc appears shallow and plano-concave in maturity, with gelatinous appearance, receptacle with uneven and felty texture, darker network of hyphae visible, stipitate, blackened in lower-part, stromatised petiole with blackened mummified appearance.<br /><br />Associates: Further up the petiole/mid-rib, several tiny, whitish, stipitate apothecia, size and colouring suggests a different species.<br /><br />Asci: ~120-130 x 10-12 um, cylindrical-clavate, 8-spored, biseriate when turgid, croziers, apical ring strongly bb, seems like typical Rutstroemia form, apex rounded-truncate, more truncate when flaccid, apical thickening noticeable when immature or flaccid.<br /><br />Spores: Reniform, apex hemispherical, base +/- acute, noticeably to strongly curved in profile view, inside the asci apparently filled with many tiny VBs but most coalescing in free spores to form ~3 large to medium VBs, apparently aseptate and uninuclear.<br /><br />Measurements in water or IKI: (12.5) 13-15 × 5-6 µm, Q = (2.2) 2.5 - 2.76 (2.8), n = 10, mean = 14.1 × 5.4 µm, Q mean = 2.6.<br /><br />Paraphyses: Long, cylindrical, irregularly inflated toward apex (~2.5-5 um), occasionally branched or bent at apex, multi-septate, apical cells filled with large yellowish VBs, possibly taller than the asci, some noticeable amyloid contents.<br /><br />Marginal cells/hairs: Multiseptate, ~2-4 cells protruding, irregularly cylindrical, apparently gelatinised, with orangish brown exudate, around margin and on flanks, associated with the darker hyphae on the surface of the excipulum.<br /><br />Medullary: Textura intricata (typica), appears to be separated from ectal ex. by several rows of horizontal hyphae, looks darker towards subhymenium.<br /><br />Ectal ex: Hyaline, narrow hyphae on the surface, textura porrecta, patches of exudate, underneath large cells, textura prismatica, cells size seems to distinguish from horizontal hyphae.

Hello,<br />On a small twig of probably Betula there were these cups with short thick stem. Fb small, 1,3 mm, stem 0,4 mm. Brown with ochre hymenium, outside looking fibrillose/hairy. Asci cylindrical, 90-115 x 7-10,5, 8 spored (biserial). Croziers +, IKI +. Cristals (?) at base of quite a few asci. Paraphyses slightly longer than asci, slender without capitate apex. Textura porrecta (I think?), endhyphae brown and very incrustated. Spores allantoid, almost bacilliform: 12,3-14,4-16,6 x 3-3,3-3,6.<br />Q= 3,7-4,4-5. Very little content within spores, no clear/bigger guttules. <br />I can't find a match within either Rutstroemia nor Cyathicula (which in the Netherlands they call Crocicreas). Does any of you have an idea? Thanks already! <br />Maria

Dear colleagues<br />Can you help me with the identification of Discomycete species which I met on the thin dead branches of Carpinus betulus in the forest litter?

Hola a todos.<br />Ayer encontramos estos ejemplares dentro de una maceta sin plantas y que tenía muchos restos de maderas quemadas sin determinar.<br />Ya siento que los ejemplares no está en muy buen estado, pero así estaban.<br />Esporas de 17-20 x 8,5-10 micras, maduras con un septo central trasversal.<br />Ascas amiloides y croziers +.<br />Al principio me pareció (ejemplar de la dcha.) que tenían esclerocio, pero al llegar a casa y partirlo, se deshizo como si fuera carbón.<br /><br /> ¿Alguna ayuda?<br /><br /> Gracias a todos.<br />Un saludo<br />Rubén

Bonjour<br />Hier « au sol », un champignon qui me pose problèmes...<br />Mais il est immature... Et je n'ai trouvé qu'un asque « à peu près formé ».<br />Il sort d'une sorte de pelote de poils, dont je ne suis même pas sûr que ce soit végétal.<br />Les cellules très longues de ces poils ne sont pas cloisonnées.<br />L'allure du champignon fait un peu penser à Baeomyces roseus, mais cela ne semble pas être un lichen...<br />Si quelqu'un avait une piste... <p>Merci de votre aide, et bon travail à tous</p>

<p>Hello,</p> <p>I found these stalked species on fagus leaf-stalk. There size is 0,6mm. Asci J+ 98/104x8/10µm. Only a few spores found outside the asci, size 14/15x4,5µm. Any suggestions?</p> <p>Regards,</p> <p> </p> <p>Ralph</p>

Dear friends,<br /><br />I'm looking for recent material of Rutstroemia (Lanzia) longipes from North America (ideally from the U.S., NY state) to study and compare with european collections. It would be also great if you can note some of the characters while still alive and in water mount, esp. paraphyses contents, surface hyphae, ascus and spore size. <br /><br />Thank you very much. <br />Viktorie <br />

Hello all, <br /><br />would please anyone have the White's monograph of Rutstroemia, Lloydia 4(3): 153-204 (1941)?<br />Thank you in advance.<br /><br />Viktorie <br />

Hello, I found something more than those mentioned ealier on Potentilla. This didn't look like Moellerodiscus, so I thogh it was worht checking. These can be almoust I mm wide and 1,5 mm high:

Bonsoir à tous,<br /><br />La semaine dernière, j'ai trouvé cet asco ressemblant fort à un Peziza sur branche pourrie de noisetier (Corylus avellana).<br /><br />a) asques octosporés, à spores unisériées, IKI- <br />b) spores elliptiques, remplies complètement de petites gutttules, lisses : 19-24x7-9<br />n.b. : certaines spores présentent un petit apicule à chaque extrémité (germination de spores secondaires ??)<br />c) paraphyses filiformes, septées, ramifiées, à contenu réfringent vers l'extrémité<br /><br />Pas d'idée…<br /><br />Bernard

<p>I have long been interested about fungi of peat bogs and wetlands in the central part of the Czech Republic. I often find the taxon Rutstremia henningsiana / paludosa in the tall-sedge beds. In the Mycobank and IndexFungorum databases are still distinguished as two species. I have read carefully the debates on the web sites Ascofrance about the taxonomy of this complex in the past. They showed that it is only one species and Rutstremia henningsiana is an older and invalid name. Has anything changed since then?</p> <p>Thank you for answer</p>

Hello, I found these on my own yard on (Betula) leaves today. These are about 0,2-0,5 mm wide:

Hello. I've found these on rotten stems of grass in a coastal sandy region of Israel. I think, I've seen them before and they are pretty common, but maybe often overlooked.<br />Fruit bodies about 2-4 mm. <br />Ascos about 160-180*18-22 mkm, 8-spored. <br />The spores are arranged in 1-2 raws, about 18-22*7-9 mkm. <br />Paraphises long and slender.

Bonsoir,<br />Jean-Marc m'a apporté une récolte de Lanzia echinophila.<br />Habituellement, je rencontre cette espèce sur bogues de châtaignier (Castanea sativa).<br />Ici, les apothécies sont sur cupule de Quercus cerris (chêne laineux).<br />Je voulais savoir s'ilexiste une forme spèciale pour ce support ou si les deux supports donnent des champignons  parfaitement semblables.<br />Merci<br />Gilbert

On a thin deciduous stick (Salix/Alnus/Betula) on moist sand I found a light brownish grey apothecium 4 mm diam. The excipulum is t. globulosa and the medulla t. intricata. The spores are (15.2)15.7-18.0(19.6) × (4.5)4.7-5.4(5.7) µm with many medium sized guttules. The asci are 128-152 × 7.1-11.9 µm and the praphyses are filled with low refractive guttules. <p>I have difficulties finding even a genus; it has much in common with Ciboria but I don't think the spores fit in.</p> <p>I would appreciate opinions on this one.</p> <p>Stefan</p>

Besançon, France.</div> <div>Ascospores : 17,5-23,2 x 4,1-5,3 µm (m : 19,4-4,8 µm), allantoïdes à cylindriques, hyalines, non septées, à contenu spumeux (vivantes) ou biguttulées (mortes).</div> <div>Asques : cylindriques, à sommet non amyloïde, avec crochet, contenant huit spores bisériées.</div> <div>Paraphyses : renflées au sommet, grêles, à contenu brun, septées.</div> <div>Il y a une récolte dans l'Ouest, mentionnée dans fongibase (Mycofrance), mais avec peu d'informations. Je vais faire quelques recherches.</div> <div>Merci<br />Andgelo</div>

As mentioned in the title. Someone a clue what this can be, family? Spores not much yet. What i dus find was beanshaped and about 17,5 x 5

Hi,<br /><br />I thought that this was a good fit for <em>H. albidus</em>, but now I'm not certain. Relatively common on rotten leaves and petioles in wet areas in Ottawa, On, Canada. <p>This was on rotten skeleton leaves and long petioles (too long for Acer). It was abundant under ferns, with Fraxinus next to them.<br />Apothecia 1-2.3mm in diam., white, stipitate.<br />Asci 8-spored, IKI+bb, croziers(-), 79-102x8.5-9.5um.<br />Paraphyses cylindrical, with  highly refracting VBs, about 3um at the apex.<br />Ascospores scutuloid, with large guttules, <br />(14.5) 14.8 - 16 (16.6) × (3.9) 4 - 4.5 (4.6) µm<br />Q = 3.4 - 3.9 (4.2) ; N = 24<br />Me = 15.4 × 4.2 µm ; Qe = 3.7<br /><br />Pictures are here:<br />https://inaturalist.org/observations/88763257<br /><br />Thank you for your help,<br />Igor</p>

(13.06.2013)<br /><br />Mud sedge (Carex limosa) litter hosts not high fungal diversity now, or probably i was not very lucky in the search. By the way, one discomycete species was abundant and there and it is new in the list. These dark olive and black discs are probably Niptera or something close. (#4193 - https://www.cubby.com/pl/%234193/_cc2c0015396b488a8557eedbb4ab2191)<br /><br />At the tips of the fallen leaves i saw some demateaceous hyphomycetes as well. And a pyrenomycete with large two-celled spores which was already spotted at cottongrass is found yet on another host. (#4194 - https://www.cubby.com/pl/%234194/_a840cf9a7137418a812842bc82bd43ec)<br /><br />And it was fine to come across one new species on previously examined substrate of Sheuchzeria. It is from Rutstroemiaceae family, commonly met at Sheuchzeria leaves which are in this case are devided by black lines. Apothecia has flat disc and long stipe with velum at the base, and brightly colored (reddish-brown), easily searchable as well.(#4192 - https://www.cubby.com/pl/%234192/_7ae331edbca84218af84c0c19a47ea44)

<p>Hello everyone. My first contribution to the forum!</p> <p>Below is a description of a cup fungus looking like a Rutstroemia which I found on a dead ivy leaf but I'm not aware of any of this genus which occur on this substrate.</p> <p>Regards,</p> <p>Charles.</p> <p>Rutsroemia on ivy leaf, Refail Fields, Pentraeth, N. Wales, 11/2/19</p> <p>Asci: 80x7, 87x8, 90x8, 87x8, 89x8, 87x8.5, 78x7, 90x8,</p> <p>Spores: 12.5x4, 2x3.5, 12x3.7, 12x4, 13x4.8, 12x3.5, 12.4x3.7, 12x3.9, 12x4.,</p> <p>Paraohyses tips: 4, 3.3, 3.5, 4,</p> <p>Excipulum textura globosa-cells thick walled.

<div>Hi all,</div> <div>Today I accidentally collected this species while taking some weakened Dicranella heteromalla. Therefore I only had the opportunity to study one ascocarp for now. Does someone perhaps know what this can be or where I have to look for a solution based on what I have so far?</div> <div>Paraphyses seemed to be long filiform, slightly curved, 2 - 2,5 um wide, branched, aseptate. </div> <div>Asci cylindrical to somewhat clavate, 8-spored 120 x 10 - 12 um, most of them immature unfortunately, spores uniseriately arranged.</div> <div>Ascospores smooth, hyaline, ellipsoid, 20 - 22 x 9 - 10 um, and becoming 1-septated (?).</div> <div>I know it is quite poor for now and hopefully I manage to collect some more of it in the near future.</div> <div>Best wishes,</div> <div>Jannes</div>

Hi to all:<br />My friend F.J. Balda have sent to me from Navarra (NE of Spain) this rare fungus that grows on semirotten wood of Quercus.<br />The ascomata are shortly stipitate by a short and stout pseudostipe and they are up to 2 mm in diam. <br />The hymenium seems to be reddening with the age.<br />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.<br />Asci IKI b of the Hymenoscyphus-type, Without croziers. Only repetitive false croziers or abortive croziers at their base. Paraphyses with multiguttulate Vb's.<br />Ectal excipulum made of a brownish textura globuloso-angularis or only angularis. Medullary excipulum textura intricata.<br /><br /><br />I feel my fungus is close to Hymenoscyphus. What's your opinion?<br />Many thanks again   <br />

Hola a todos/as<br />Adjunto fotos de unos ascomicetes que he recolectado hace unos días en los nervios foliares de Cydonia oblonga.<br />Apotecios de hasta 3mm.<br />Esporas de 10.1 [10.9 ; 11.2] 12 x 4.6 [5 ; 5.2] 5.6 µm, con dos gotas amarillenta en los extremos.<br />Ascos octospóricos, inoperculados, de 78.9 [94.6 ; 107.3] 123 x 8.5 [9.2 ; 9.8] 10.5 µm, IKI+, con la base pleurorrincas y con croziers en la base.<br />Paráfisis con el ápice clavado, con septos, numerosas VBs y ramificadas cerca de la base.<br />Excípulo medular de textura intrincada.<br />Excípulo ectal formado por células más o menos globosas, en la parte más interna presenta hifas dilatadas en forma de dedo y con incrustaciones.<br />Consultando biografías creo que podría tratarse de un Moellerodiscus sp.<br />Agradecería vuestro comentario.<br />Saludos<br />Curro Valencia

Re-bonsoir. Voilà un très beau champignon trouvé dans une mouillère dans les PO à 1700m d'alt. sur une branche de bois (à proximité : aulnes, hêtres, bouleaux) indéterminé. Macro : Ascome haut jusqu'à 9mm ! cupuliforme à orbiculaire étalé. Hymenium de diamètre 6 mm max, crème grisâtre. Excipullum furfuracé. Excipullum et stipe (jusqu'à 6 mm de haut) crème-grisâtre un peu plus foncé que l'hymenium. Ne rougit pas à la blessure. Micro : Spores incurvées, 20-25x6-7 um remplies de guttules de 2 à 3 um de diamètre. Asques 70-90x10-12 um, IKI+ dans le Lugol. Spores unisériées. Boucles + Paraphyses larges de 4 um, septées, remplies de guttules non réfringentes. Avec les clés dont je dispose, je n'arrive à rien de convainquant. Pouvez-vous m'aider dans cette détermination ? Merci par avance. Yannick Mourgues

Hello,<br /><br />would anyone recognize this nice Hymenoscyphus? <br />H- , short but "inflated" scutuloid spores, yellowish VBs, excipulum t. prismatica<br />Substrate is a stromatized petiole, based on the cross section it might be Acer (definitely not Fraxinus which has many more vascular bundles), one collection was directly under Acer negundo. Riparian hardwood forest, place shaded from draught. <br />It think it's related to Andgelo's collections here:<br />http://ascofrance.fr/search_forum/54432 and http://ascofrance.fr/search_forum/49925<br /><br />Thanks a lot in advance. It will be sequenced but I don't really expect to find a match in GB. <br />Viktorie

I have seen sclerotia of, likely, this species several times before in stems of Rubus chamaemorus. Apothecia were found for the first time, in this case they arise from a berry of the same plant. Date of collection: 02.06.2014. Coordinates: N60,891704° E68,684973°<br /><br /> <p>Apothecia cupulate with long stipe, up to 2.5 cm long, disc 2.5 mm across, light brown, hymenium light yellowish-brown, upper part of stipe pubsecent under lens, arise from short cylindric sclerotia, 5 apothecia collected from one old berry, sclerotia attached to seeds.</p> <p>Asci cylindrical with narrowed base, with crozier, with euamyloid ring, 4-spored (but irregularly one to 6-spored asci seen, with part of spores abrupt, many of asci were also underdeveloped and empty), 108-119 x 9.5-11.3 mk; paraphyses cylindrical, moderately branched, with many small greenish guttules, 2.4-3.7 mk broad in upper part; spores ellipsoid, inequilateral, with two small guttules at both ends, 13.1-15.5 x 6-7.5 mk (n=7, only large not abrupt spores measured).</p>

Hi everyone,<br />I found this stromatic fungus growing on the wood of _Castanea sativa_. The stroma is brown and exsudes a red pigment in KOH. The asci are very long<br />and thin, up to 150 x 6 µm, unitunicate, apically amyloid, and contain 8-spores each, uniserially arranged at the top. The spores are one-celled, hyaline when<br />young and soon brown, guttulate, with the following dimensions:<br />(6.7) 6.9 - 7.7 (8.1) × (3.3) 3.5 - 4.1 µm<br />Q = (1.8) 1.81 - 2.1 (2.2) ; N = 27<br />Me = 7.4 × 3.8 µm ; Qe = 1.9 ,<br />which are much smaller than my previous observations of similar fungi. Can someone help me in give it a name?<br />Thanks in advance,<br />zaca

Bonsoir à tous,<br /><br />-Habitat : Sur feuilles de Quercus rubra, également sur bractées de Carpinus. <p>-Description macroscopique : Apothécies ± confluentes 2,5-4 mm de diamètre, turbinées. Face supérieure jaune paille, avec la marge finement crénelée et avec un reflet lilacin. Face inférieure blanchâtre.</p> <p>-Description microscopique : Spores 18-26 x 3,8-4,5 µm, cylindriques/elliptiques et ± arquées avec les extrémités aigues, avec un côté plus bombé que l'autre, farcies de gouttelettes au extrémités. Asques octosporées bisériées, 100-150 x 8-13 µm, pleurorhynques (base bifourchue). Sommet faiblement amyloïde (l'anneau apical est constitué de deux traits parallèles). Paraphyses grêles, cylindriques, 100 x 4 µm, farcies de goutelettes refringentes. Chair à excipulum médullaire de textura intricata et excipulum ectal de textura globulosa prismatica avec quelques poils courts et septés.<br /><br />Je pense qu'il s'agit d'un Phaeohelotium. Avec cet aspect et cet habitat, je ne dois pas être loin de epiphyllum mais les spores ne vont pas trop...<br /><br />Merci d'avance pour votre aide !<br /><br />Andgelo</p>

Bonjour à tous Dans le reste de l'incendie, brûlé des rameaux d'olivier sur le carbone. cendre. ce que je lis dans la description de ciboria, je ne trouve rien dans les restes de charbon Esporas 12-17,bigutuladas aux pôles o no Paráfisis cloisonnées, non fourchues Asques 145-160 microns Excipulo ectal,textura globulosa. hyphes de excipulo crois que conduire à ciboria. Mais j ai ne faut pas voir de toute autre plante, seul le charbon. ¿qui croyez? Saludos Pablo Chacón

Bonsoir à vous, pas capable de trouver le genre, si mes examens sont corrects, ce dont je ne suis pas sûr... Sur tronc couché de merisier décortiqué, par centaines. Jjusqu'à 1 cm de long. Stipité. Asques à bouchon apical J+ Spores en corne, 20 x 6-8 microns, avec une grosse guttule lumineuse. Paraphyses ramifiées, à peine élargies au sommet à 2 microns. Merci de votre aide jean pierre

Dear all, <p>I recently found a specimen of Durella macrospora which agrees well with the registered sequence. This will be a new report from Japan.</p> <p>To confirm, I would like to see Medardi G. 2004. Documents mycologiques 33: 29-35, which was cited in your article in Willdenowia (47: 271-291).</p> <p>Is there anybody who can provide me with the copy ?</p>

<p>the bright yellow stipitate apothecia remind of a Sclerotiniaceae - the euamyloid ascusporus could confirm this.</p> <p>The ectal excipulum of brownish cells have swollen end-cells with bright yellow vacuolor content - as have the parapyhses. The spores are about 9,5-12/4-5 µm and ciboriod - a lot of asci were still unripe. I will try to find this again and make better macrofotos.</p> <p>But - I think this is a very striking species somebody of you should know.</p> <p>Who is it?</p> <p>Best regards from Lothar</p>

Small, 2-8mm diameter ascocarp, yellow-honey, almost flat, with a smooth glabrous margin, stipe 2-3(4) times the diameter of cup, growing on fallen leaves of Ceratonia siliqua, usually in groups, but not in tufted clusters <br /><br />Asci slender, J-ve with Melzer, but a faint blue lining with Lugols on apex. Sealed, without operculum, spores released through a pore which becomes outrolled like a roman vase when ascus is empty. 8 ascospores per ascus, compact, diagonally packed around each other.<br /><br />Ascospores spindle shaped, slender, not septate, with 3-6(8+) small oil bodies that tend to gather at the poles of the spindle shaped spore.  <br /><br />When I applied KOH on the ascocarp,  it became duller (greyish yellow) but no red tonality. Perhaps insignificant. <br /><br />Micro:<br />Spore length range: 7.5 - 11.31 µm<br />Spore length mean: 9.6 µm<br />Spore width range: 2 - 3 µm<br />Spore width mean: 2.6 µm<br />Spore Q factor range: 3.19 - 4.52 µm<br />Spore Q factor mean: 3.68<br />Spore shape: Spindle, slender<br />Spore septa: 0 (no speta)<br />Spore surface: Smooth<br /><br />Ascum average size: 75 µm x 6.3 µm<br />Iodine reaction: J -ve (faint blue apical lining with Lugol's Iodine)<br /><br />

Buenas noches, Necesito alguna idea para empezar a buscar sobre hojas de olivo --------------------------------- Bonnes nuits, J'ai besoin d'une certaine idée pour commencer à chercher sur les feuilles d'olivier Merci Pablo Chacón
