Hi all. Apothecia discoid, black, growing on wood of Quercus. Size up 800um diameter. Spores hyaline with 9-11 transverse septa and 1-2 longitudinal septa. IKI (-). Asci containing many conidia? Paraphyses filiform, septate, divided. (x 1-1.5um). I think it may be next to Patellaria, but I have no information. Any ideas. Thanks in advance. Susana (Spain)

Patellaria on Tilia

Hello all, this is a today's find on a dead branch of Tilia. I found the same or similar one in January but could not end in a "terminating" determination. So here is another try:

Patellaria "crassispora" on Arundo

Hi everyone, These specimens were found in the same day than the Patellaria atrata considered at http://www.ascofrance.fr/search_forum/42904 in the nearby sand dunes on an old piece of Arundo. The main differences for that species are the existence of a blue pigment in the epihymenium and the wider spores, for which got the following dimensions: (29.9) 30.8 - 39.3 (42.8) × (6.9) 7.1 - 9.3 (10.1) µm Q = (3.5) 3.7 - 4.8 (4.9) ; N = 31 Me = 35.5 × 8.2 µm ; Qe = 4.3 Again, if I understood correctly the comments by Zotto regarding my topic http://www.ascofrance.fr/search_forum/37495 this should be Patellaria crassispora. However, I don't know if this name is valid; I could only find references to Patellaria crassispora Baral nom. prov. from 2010. Maybe Zotto can add some information about it. Thanks, zaca

Patellaria crassispora?

Hi! Good night! I collected this Patellaria in dead plant of Baccharis halimifolia. I followed the documents on Baral's website and found P. crassispora who seems to me to be a good match or at least similar. But since her situation is not so clear yet, and she is still a species under study, I would like to receive any help regarding her. It has a bluish hymen and slightly blue multi-nucleated spores. Any help is welcome! Thanks you very much! Unai!

Patellaria-like fungus

Hello. I found a very small Patellaria-like fungus, growing on decorticated dead branch of Quercus. The apothecia are 0.2-0.5 mm in diam. Asci with crozier, IKI+ (bb), with 8 biseriate spores. Paraphyses very thin, ~ 2 µm in diam. Ascospores clavate, 16-20 × 4-4.2 µm, hyaline, with 1 to 2 septa (outside the asci), with some minute guttules. The excipulum appears olive in 5% KOH (see attached picture, although a bit darker here). Any suggestion?

Viktorie Halasu, 03-05-2020

Patellaria crassispora?

Hello, would this qualify for Patellaria crassispora, or is it just another P. atrata? The exudate looked more blueish than I'm used to see. Growing on lower side of a lying partly decorticated Fraxinus branch, rather wet wood, quite the opposite as where I usually find P. atrata. Asci H+. Thank you in advance. Viktorie

Patellaria ? Black apothecioid with white subiculum

<div>I found these minute black apothecioid ascos on bare hardwood last weekend in New York City. They occasionally grow on a white subiculum. The discs are less than 1mm in diameter. Asci are IKI- and 65-75 x 10µm. Spores are hyaline and multiseptate (14-) 19-25 (-27) x 4-5.5µm. There are filiform paraphyses which end in a brown, swollen tip. The tips measure 3-4µm wide. I keep coming back to Patellaria. Anyone have an idea what these could be?</div> <div>Thanks in advance.</div> <div>Ethan</div>

Maria Plekkenpol, 22-01-2020

Patellaria atrata??

I found these on bark, most probably Salix. I think/thought Patellaria atrata, but I read an older topic (2016) in which was said that wider spores could point at P. crassispora. I don't see blue-ish colouring anywhere and couldn't find much about P. crassispora either. Spores av 47,5 x 9, Q=5,31 (20 spores measured). Is this P. atrata? Thank you! Maria

Patellaria atrata (?) on Juniperus

Hi everyone, If I understood correctly the explanations given by Zotto in my previous topic http://www.ascofrance.fr/search_forum/37495 this is again Patellaria atrata. It was found in the same region than the previous (Lourinhã, Portugal), but now oudoor and growing on the roots of Juniperus at a cliff over the sea. This time I could observe living spores, guttulate, with the following dimensions: (31.7) 34.9 - 45.4 (49.4) × (5.1) 6 - 7.4 (8) µm Q = (4.2) 5.1 - 6.8 (6.9) ; N = 34 Me = 39 × 6.7 µm ; Qe = 5.8 I attach some photos of the specimens and from the corresponding microscopy. Someone can confirm it? Thanks in advance, zaca

Peter Thompson, 19-12-2013

Patellaria or Lecanidion

Hello Everyone, I have been considering an ascomycete which seems to be growing in association with a lichen or alga. There is a slimy, green film on the wood, which is decorticated Betula pendula. In many ways, it seems to fit best with the genus Patellaria (long, multiply septate spores, asci which rupture at the tip, no reaction to lugol and parallel, regularly septate hyphae in the excipulum). There seem to be inconsistencies as well (olive green hymenium and paraphyses neither branched nor swollen at the tips). I have attached a photograph of the fruit bodies and a sketch of the microscopy and wonder if anyone has an idea as to what it is. Thank you, Peter.

Patellaria atrata?

Found near Cle Elum, Washington, USA On decorticated Abies trunk lying on ground "Apothecia" are quite gelatinous when fresh but very brittle when dried. Difficult to get good sections. Seems immature as there are no free spores but a few asci with multiseptate spores within. Very thin, branched paraphyses. I was wrong. Asci do not blue in Melzers. It was some of the subhymenial hyphae I have added oil immersion views of asci and paraphyses mounted in Melzers

Hysterium?

Hola: Especie que crece de forma gregaria sobre corteza de arce colonizada por liquenes. Tamaño de los ascomas, en torno a 0.5mm. Microscopicamente se observa gran cantidad de pigmento azul en la zona apical del himenio. La mayoria de las muestras observadas estaban en un estadío inmaduro, por lo que puede que las esporas mostradas no estén totalmente maduras, es posible que hayan salido de las ascas al preparar la muestra. Pienso que podría pertenecer a la familia Hysteraceae y dentro de ésta al genero Hysterium. ¿Que opinais? Gracias. Susana Hello: Species that grows gregariously on Acer bark colonized by lichens. Ascomata size, around 0.5mm. Observed microscopically lot of blue pigment in the apical region of the hymenium. Most of the samples were observed in an immature stage, so that the spores can not be displayed fully mature, you may have left the asci during sample preparation. I think it might belong to the family Hysteraceae and within it the genre Hysterium. What do you think? Thank you.? Susana

Help with a black discomycete

Hello. A few apothecia collected on Sunday, April 7, under beech and oak trees, on the stripped surface of a trunk lying on the ground, sharing space with what appears to be Orbilia eucalypti. Ascomas in the form of black grains of about 0.7 mm. in diameter, little rooted in the substrate. Hyphae of the excipule angular, more or less rectangular, strongly pigmented. Octosporic asci, apparently bitunicate, with measurements of (75.8) 78.9 - 96.8 (101.9) × (11) 11.1 - 14.4 (16.1) µm. with an average of Me = 89 × 12.9 µm., without any considerable reaction to Lugol. Interascal matter like a paraphysis, filiform, with a width of just 1 µm, with a dark amorphous substance at the apex and protruding slightly above the level of the asci. Free ascospores scarce in the samples, these ascospores between fusiform and moriform, with a somewhat more pointed end, with 8 to 10 transverse septa and some longitudinal septa, with measurements of 15.1 - 21.1 × 4.8 - 5.4 µm. Any suggestion from you will be welcome. Thank you very much in advance. Kind regards.

Dense black disks which became somewhat pulvinate when hydrated. The largest approaching 1mm in diameter. Asci with 8 spores, bitunicate, about 138-148 x 24-25µm. IKI- Spores muriform, at first hyaline, finally dark brown, 4-7 septate with longitudinal septa. 25-33 x 10-13µm. It appears that the spores inside the asci are at the larger end of the scale 31-33µm long while the darker spores loose in the centrum are somewhat shorter 23-27µm. The outer layer appears to be a dark, agglutinated (?) layer appearing red in projected light. It was very difficult to discern any paraphyses or other features. Because of the resemblance to Patellarioid ascos, I had thought it might be Tryblidaria, but perhaps that's not a very good fit. Can anyone provide me with a shove in the right direction? Thanks!

Claussenomyces atrovirens?

<div>Hi!</div> <div>Black (when dry), solitary or somewhat clustered, sessile to very short-stipitate apothecia on dead, decorticated branch of Pinus sylvetris, Central Norway.</div> <div>Asci 75-125 x 12-18 microns (in water), IKI-. Asci mostly with granular contents, but a few beginning to form septate spore, difficult to measure presicely. Paraphyses agglutinated in a greenish/olivaceus matrix (resinous material?), apparently with transverse, elongate "bodies". Subhymenium brownish.</div> <div>I wonder if Claussenomyces atrovirens can be this dark when it dries. Is Patellaria atrata an option?</div>

Hysterobrevium mori (?) on Juniperus

Hi everyone, I found this lirellate fungus on the roots of a Juniperus shrub. Some of its micro features are: Asci: cylindrical with up to 110 µm in lenght and ~12 µm in width; Spores: - hyaline at first, soon pale brown and later brown; - 3 to 6 transversal septa and 1 longitudinal septa in one or several middle cells; - dimensions: (14) 20 - 23.7 (27.5) × (6.1) 6.3 - 7.4 (7.6) µm Q = (1.9) 2.9 - 3.5 (3.7) ; N = 31 Me = 22 × 6.8 µm ; Qe = 3.2 Initially I thought that it could be Hysterium, but the spores are more tranversely septate and, moreover, also have a longitudinal septum. Looking to the information avalable at http://www.eboehm.com/hysteriaceae.html I realise that most probably it is a Hysterobrevium sp.. There are only three species mentioned in this genus: H. constrictum, H. mori and H. smilacis, the first and the third with hyaline spores at maturity, leaving Hysterobrevium mori as the possible candidate for the classification. Is it so or are there other choices? (at the "Key to the species of Hysterographium, Hysterobrevium and Gloniopsis" two other genera are considered but with different features, as far as I can understand. Recently I found a species of Hysterographium but never found one of Gloniopsis.) I would like to have comments or remarks about this uncommon (for me) find. I attach a set of photos. Thanks in advance, zaca

Tympanis

Chers amis, Sur branche morte de Pinus strobus trempant dans un ruisseau, sur l'écorce, fructifications plutôt isolées de 1mm de diam, pulvinées surélévées, puis en tartelettes en séchant. Paraphyses ramifiées septées coiffées de brun. Conidies en saucisses, hyalines 2x1 microns. iode douteux. Qu'en pensez-vous? Nous n'avons aucune expérience des Tympanis. Et c'est dans Ellis que nous avons vu ce Tympanis hypopodia, possible... Merci de nous éclairer. jean pierre

Possible Triblidium caliciforme

I would appreciate some help with identifying this unusual ascomycete. I must make it clear that I was not able to examine the material in the live state. I received it as a dried collection from Kerry Robinson from Hertfordshire. It was collected on a rotting deciduous log. Apothecia very dark, rather leathery, up to 2mm. Apothecial marhin intact, not torn as so often seen in Triblidium. Sections show an epithecium/covering layer of a similar structure to the excipulum. Paraphyses filiform and very numerous. Asci not reacting to Lugol's, they contain a variable number of spores that reach maturity. Spores are up to 28 x 8 and are always muriform, Any help mucg appreciated.

Polysporous black discomycete

<div>Hello all, </div> <div>I was in California and found this small black polysporous asco. Macroscopically it looks quite a bit like Patellaria atrata, though the apothecia are a little bit smaller. It has bitunicate asci with (estimating) 32, or maybe 64 ascospores inside? The ascospores are small, hyaline, fusiform-ellipsoid, measuring 3-4 x 1.5µm. Asci IKI-. The dark (glutinous?) material among the asci and paraphyses does not dissipate in KOH. Is it lichenized? I'm not sure. Any help would be appreciated.</div> <div>Thank you, </div> <div>Ethan</div>

resembles Patellariales on resupinate toothed basidiomycete

Perhaps someone has some insight on this and can help me understand what's going on. From New York City, growing on hardwood on/near a resupnate toothed basidiomycete, size up to about 1mm diameter. It resembles (to my eye at least) something like Patellaria atrata. But microscopic features include asci with irregular, lumpy spores alongside asci with what appear to be elongated multi-septate ascospores. Asci are approximately 75 - 100 µm, bitunicate, IKI-. No free spores observed. Treated with Lugol's or Cotton Blue, the irregular spores seem to dissolve or otherwise disappear, but the longer septate spores persist. The fertile surface has a dense layer of green pigmented material. Has anyone seen this before? Thank you in advance!

is this an asco?

Hello, ik like to ask some support. On a small twig I found thes little cups. It seems that the beginning of these cups is an orange disc, which later turns into a little hairy cups. The inside of the caps atay orange. I don't know which tree it belangs that's why there is a picture of the twig. The measure of thew asci were about 35 µm. the sporen between 6-8 x 2-4 µm, J- with Melzer. I ordered Barals. I dont know if it belong to the Criptodicus? Has anyone have an idea for me to look for?

lophiostoma à grandes spores

Quelqu'un aurait-il une clé concernant le genre Lophiostoma ? Je viens d'en rencontrer un certain nombre sur feuillus et je ne connais pas toutes les espèces potentielles existantes. Une remarque pour Jacques : je viens de retomber sur le message du 29-12 "sur Hedera" et je suis maintenant convaincu que j'avais sous la main un exemplaire des lophiostomaceae comme tu me le suggérais. L'aspect macro et le peu d'éléments micros dont je disposais collaient bien avec le genre Lophiostoma. Mais n'ayant plus le matériel...dommage ! Alain
