Podospora pleiospora posible

There is some doubt in how we address this species. Mirza & Cain handled it as P. fimicola and Lundqvist as P. fimiseda so which one is correct? In Mycobank P. fimiseda and P. fimicola share the same basionym namely Schizothecium fimicolum by Corda of which the drawings correspond with todays Schizothecium species having agglutinated hairs. Fungorum Hucusque Cognitorum Tomus II: 29 & table XIII fig. 105 - 12a (1838) Rabenhorst in Botanische Zeitung 14 Stück 24: 429 (1856) cited that Podospora fimicola (Cesati) = Schizothecium fimicolum Corda however according to the drawings shown in Hedwigia 1(15): 103-104, tabel XIVA fig. 1-11 (1856) they do not correspond to the drawings from Corda as mentioned above, but they do correspond with the current species P. fimicola or P. fimiseda. I am still searching for the documentation of Cesati & de Notaris about Podospora fimiseda but until now no succes. It may clarify some things because Niessl noted them in Hedwigia 22: 156. Joop

Podospora intestinacea

Found it on horse dung today but also found yesterday it on cow dung. Asci not measured Spores: 48-51x25.5-27.5 um; pedicel 27-29x9-13 um surrounden bby a hyaline sheat; upper and lower cauda consist of two parts, lower cauda connected to end of pedicel. It looks as if the uppers cauda has a collar near the spore head (photo 6) Cauda's are cilindrical whereby the upper part is bigger than the lower part (photo 7 and 8)

Podospora sp

Bonjour à tous Deux à trois mois après une pratique de culture en chambre humide de crottin de cheval et avant de les abandonner j'ai fait une ultime observation et ai eu la surprise d'isoler 3 périthèces d'une espèce de Podospora. Les périthèces obpyriformes d'environ 1000 x 500 µm, brun-noir, membraneux et recouvert de poils hyphoïdes (que j'ai initialement ris pour des moisissures), sauf au niveau du col, glabre, cylindrique, tuberculeux et assez coriace. La taille assez remarquable des spores: - tête noire 45-50 x 25-26 µm - la queue hyaline 25-27 x 9-10 µm et la présence sur quelques rares spores (parce que d'observation délicate) d'un appendice apical, gélatineux, en forme de ruban m'orientent vers P. intestinacea. Comme je n'ai aucune certitude, je fais donc appel à votre aide . Merci d'avance. Amitiés Alain

Polysporous Podospora, P. granulostriata?

Found on cow dung. Perithecia: 342x131 um; neck 97x61 um; covered with small septated setae 12.4-14.4x3.4-3.9 um. No asci found. Spores: 53-55.5x26-28 um; pedicel 35-42x3.9-5.2 (base)x7.8-7.9 (top); upper cauda, hollow 163x9.6 um; secondary cauda at the top of the pedicel 90-97x6.5-6.75 um. Greetings, Joop

Joop van der Lee, 12-08-2013

Schizothecium pilosum

Found on horse dung. Riged and agglutinated haris arise from the neck base, they are septated with a rounded top 79.12-91.01x2.21-2.47 um. Asci: 218.91x14.24-28.61 um, 8-spored with a long, lobate stalk. Spores: Biseriate, when young filled with a lot of bubbles, 19.78-24.49x11.30-11.54 um, pedicel 14.24x4.63 um, caudas at each pole are present. Caudas were only visible on young spores while in the ascus they collapse quickly when spores are mature.

M. M. Gotink, 26-05-2010

On rabbit dung this time, which I also keep in a moist container since a few weeks. A rather big Podospora with real hairs on the neck and polysporous asci. Fruiting body 1000-1100 x 580 µm. Hairs on neck present, septate, up to 250 µm long, 3-5 µm wide. Asci with many spores, it looks like way more than 128, likely up to 512. Spores 2-celled, main brown cell 18-23 x 12-13 µm, hyaline pedicell 12-14 x 3-5 µm, appendages variable, often long and slender. Both pedicell and appendages apparently easily released in mature spores. Having more than 128 spores per ascus and given the spore size only P. granulostriata is possible according to Ellis & Ellis. But I don't have any good description of that species, and I read somewhere P. setosa and P. tarvisina are also closely related? I would like to have some more information on these species. Can this be P. granulostriata, or are there other possibilities? Martin

Another Podospora question

This is yet another Podospora which has developed on a collection of rabbit dung (along with P. (Schizothecium) tetraspora, P. fimiseda and P. pleiospora). It seems to sit uncomfortably between P. setosa and P. curvicolla. For the former are characters like the shape of the asci (clavate, not saccate), no asci with 256 spores and the gelatinous appendages which are persistent on the mature spores and do not disappear in water mounts. But the spores seem small for P. setosa and would fit better in P. curvicolla - they measure 16.4-17.3 x 10.4-11.7µm; also in some cases the hairs could be considered 'agglutinated'. I know there are ASCOFrance members with lots of experience of these coprophiles, and would again be grateful for assistance. Cordialement Chris

Podospora/Schizothecium on hare dung

Good evening, I found this Podospora/Schizothecium on hare dung, a few days ago. Fruiting bodies 400-550 x 250-300 µm, blackish-brown to black, usually only the tip protrudes above the subtrate. No real hairs seen, sometimes there are a few thin ones (~2 µm wide) on the base of the fruiting body, but I can't exclude they belong to the dung. Neck containing agglutinated hairs, forming triangular scales with a dark tip. Asci 8-spored. Spores with one brown cell, 17-19 x 10-11 µm, one pedicell, 6-8 x 2 µm and often there is also 1 appendage (cauda) visible on the other side of the spore. This appendage falls easily from the fruiting body, resulting in free spores often missing this appendage. Given the agglutinated, scale forming hairs it should be a Schizothecium. Using the key in Ellis & Ellis leads me to S. vesticola. But according to the description in 'Fungi fimicoli Italici' and 'Coprophilous fungi in New Zealand. I. Podospora species with swollen agglutinated perithecial hairs' this species has 2 long caudae, I've only seen one rather short cauda. Another possibility could be Podospora fimbriata, but I can't find a good description of that specie, but the little information I found stated this species is found on goose dung and doesn't have caudae. Most of the other species seem to have different spore sizes, or obvious hairs. Martin Fuiting bodies:

Podospora granulostriata ?

Found on dung of roe deer. In detail it differs from P. curvicolla when referring to the drawings in Fungi Fimicoli Italici. In particular because of the very long hairs that arise from the base of the neck and the upper cauda which is solid i.s.o. consisting of strings as shown in the drawing. Perithecium: not measured, neck small covered by septated hairs rising up to 180 um from the top of the neck and up to 445 um from the base of the neck. Paraphyses: Not observed Asci: containing 512 spores, measuring 358-96 um without the long stalk. Spores: 20.5-22.7x12.3-13.4 um; pedicel 10.8-12.0x4.2-5.2 um constricted at the base; upper cauda solid 26-30x2.5-3.0 um showing rings starting at the base; lower cauda connected to the top of the pedicel consisting of 4 strings 25.0-27.0 um.

Puzzling Podospora

<div>Bonjour tous d'une Angleterre très pluvieuse!</div> <div>This Podospora is fruiting in quite good numbers on the paper around incubated sheep dung (it would be hard to find it on the dung itself which has been densely colonised by Ascobolus michaudii and Iodophanus carneus).</div> <div>So far I have examined two perithecia: one of them showed a small tuft of stiff hairs around 85µm long, the other apparently only a single such hair (both shown in the images). The perithecial wall is rather thin and not composed of the expected textura-prismatica - see the images which show abundant, long flexuose hairs (circa 2.5µm wide) and parallel short pairs (occasionally threes) of darker pigment.</div> <div>Asci are consistently 64-spored, young ascospores of the "spoon" type and mature ascospores 17-18.2 x 10.3-11.2µm. The spore pedicels are thin-walled, readily collapsing, and secondary appendages almost entirely absent (or disappeared) the images showing vestiges of an apical and a distal appendages were all I could find.</div> <div>This appears to key out to Podospora collapsa were it not for the stiff apical hairs. I need to check how consistent these are and whether they may be absent altogether on other perithecia.</div> <div>The literature is rather thin on P. collapsa, so I would welcome any suggestions. I can produce more images if required.</div> <div>Amitiés, Chris</div>

This fungus produced a good number of perithecia on dung of roe deer, Capreolus capreolus, collected in a marshy clearing in a Betula/Salix wood, with Sphagnum, Polytrichum and Phragmites nearby. The dung had been incubated for a little over three weeks. I have read with interest the various threads on ASCOFrance concerning these sometimes confusing polysporous Podospora species. After much deliberation I am fairly confident that this is Podospora granulostriata. These are the reasons: * Perithecia mostly-immersed and with stiff, non-agglutinated hairs at the neck. I appreciate this still leaves a number of other 'possibles'. * Number of spores per ascus; I did a careful calculation based on the area of the spore mass in the left hand mature ascus in the attached image, divided by the area of an individual spore at the same scale. The result was a factor of over x200; so allowing for slight flattening beneath the coverslip a total of 512 spores seems highly likely, certainly much higher than 256 spores. * Spore dimensions: 20.7-22 x 13-14µm. * Granulose spore appendages, easier to see than to photograph, but an example can be seen here. * I have noticed in a different thread that Michel Delpont has commented on contrictions at the septa of the hairs being significant; I observed that feature here. * Habitat: Lundqvist in SymbolBot.Upsal vol. 20 (1972) comments: "All examined gatherings, certainly the German and Hungarian too, have been found in forests, and it is likely that P. granulostriataprefers this milieu and cervid dung". As always comments and opinions would be very welcome. Amitiés Chris

Encore une Sordariale fimicole

<div>Bonjour tous</div> <div>A recent collection of dung from mountain hare Lepus timidus was seen to have a perithecium of this species even before incubation commenced. Examination with Nomarski DIC gave an opportunity to look for the gelatinous appendages normally invisible without indian ink (which was later used to double-check the identification). The perithecium only contained asci at various stages of immaturity, some old collapsed spores and numerous fully mature ones no longer in their asci.</div> <div>So these images show the latter, as well as a couple of submature spores which show the asymmetry well. I thought fellow copromycologists might be interested. As you can see with DIC the apical appendage shows quite well as a sort of gel sheath, with a definite margin - hard to see in indian ink mounts which are of necessity more diffuse. I was not able to distinguish the basal appendages with this technique, perhaps because the spores were not fresh out of the asci.</div> <div>Another feature I noticed - though forgot to photograph - was that the pedicels were consistently of a distinctive shape. Unlike the simply rounded club-like pedicels one generally sees in Podospora these had a rather "pinched out" apex, a little like a teat.</div> <div>Amitiés, Chris</div>

A beautiful piece of art by Podospora setosa species

Found on rabbit pallets. I have never seen this phenomenon during my research, the resease of asci from P. setosa. In a field of P. setosa of over 50 species the process of asci release was in full swing. At first a sticky bubble is released out of the ostiole channel and after that one by one the asci are creating these small pieces of art. Photos 1 & 2 are showing the ongoing process fisrts one is coming out and 5 seconds later the second one joins. The other photos are final crations. Joop

Podospora?

Bonjour, Dans le cadre de mon doctorat (géographie/paléoenvironnement) je m'intéresse à divers microrestes (ou microfossiles) préservés dans des sédiments tourbeux des Pyrénées Atlantiques. Parmi ces microfossiles, il y a beaucoup de spores colorées et notamment des Sordariales. Il y a peu de critères utiles à la détermination mis à part les spores dont les équipements gélatineux et pédicelles hyalins ont le plus souvent disparu. Les spores sont groupées par critères de ressemblance dans des « types » qui, je le suppose, peuvent regrouper un plus ou moins grand nombre d’espèces. Voici parmi la quantité de spores répertoriées 5 types de spores qui me font penser à des ascospores anciennement pédicellées de Lasiosphaeriaceae; des Podospora ? Par manque d'expérience en mycologie, il m'est difficile d'être affirmative ou d'aller plus loin! Pouvez-vous m'aider sur ces déterminations ? Merci pour votre aide, Spores 1 (T368) - Podospora Ascospores : env. 30-40 x 16-23 µm Ellipsoïdales, parois lisses, pore subapical annelé ; Pédicelle parfois présent ; un petit mucron au centre de la base. (Type de spores très commun pouvant être abondant).

Cercophora?

Found on cow dung. Starts with one-celled longitudinal oval spores without oil droplets in asci containing 8 spores. Spores extend forming oil droplets and develope a spore head quicker than is the case with Cercophora. Later two-celled with a very long pedicel 46,5x6 um average, no caudae. Sporehead 36x23 um average. Ripe spores without pedicel 37.44x39.71-24.02-24.25 um. It is not what I had expected for a Cercophora but for the moment I do not have any clou what it might be.

Arnium?

Hello, I wonder if this one could be an Arnium? Ik could only find young asci. The other ones I pushed down, sorry. The only thing is that the spores are really big, I think. The measure is 32-36x20-25 um. At the top of the frb are some at setae looking subjects ( I don't know the right word). Maybe some of you know if I'm thinking right, but it could also be something else. greetings Hannie

Schizothecium tetrasporum

Found on deer dung, The fact that pedicel and upper cauda are covered with a gelatinous layer does not heve much attantion in documentation. In my opinion it is best described in "Coplrophilous fungi in New Zealand. I. Podospora species with swollen agglutinated perithecial hairs" Mycologia 87(3) 1995 pp. 375-396. Under Podospora tetraspora page 393. Perithecia: 574x237 um; neck and area just below the neck covered width short hairs; one third of the body covered with agglutinated hairs 38-46 um. Asci: 81-spored; 196-204x22-24 um Spores: 21.8x12.1 um; pedicel 8.2-9.1x2.1-2.5 um, at least two lateral cauda at the base of the pedicel, pedicel covered with a gelatinous layer; upper cauda 13-15x1.1-1.6 um, cauda covered with gelatinous layer originating on both sides of the germ pore. Residue of lateral caudea on base of the pedicel is visible by means of black or lighted spots. The same is visible with the gelatinous layer around the upper cauda originating just beside the germ pore. It is exeptional to see that the width of the pedicel is greater with immature spores than with mature spores. 3.2 um against 2.3 um. Photos 7-9 are from a S. tetrasporum with a smaller spore size 15.3-18x8.2-9.2 um and found on rabbit dung. Perithecia: 398x215 um. Photo 8 shows the gelatinous layer around the pedicel. Photo 9 shows the gelatinous layer around the upper cauda originating on both sides of the germ pore. Joop

Recherche Arnium arizonense

Found on hare dung. I finally managed to visualize the gelatinous equipment as mentioned by Lundqvist. Upper cauda 245x7.5 um, starting with a width of 31-38 um originating from the flat side of the spore. Besides that the flat side is covered with a gelatinous layer that does not directly have any contact with the upper cauda, sheath has a width of 10.5 um. Lower cauda covering the pedicel and extending to 223x9.5 um. Joop

Podospora globosa ?

Un Podospora récolté sur crottin de cheval en culture. Périthèce globuleux avec fin chevelu (poils 1,5-2 µm de diamètre) Asques bisériées ( sur un exemplaire quelques asques sont difformes les spores se concentrant au sommet de l'asque) 310-347 x 30-49 µm, Spores ellipsoidales 40-55 x 21-26 µm, avec un appendice caudal à sommet le plus souvent arrondi, parfois apointi (21-30 de longueur, largeur au sommet de l'appendice 9-12 µm). Le problème pour en faire des P. globosa c'est que l'on trouve occasionnellement un appendice gélatineux au sommet de la spore, comme montré dans les photos ci-dessous

Cercophora Septentrionalis?

Found on horse dung. Eventhough the spores are not mature yet, my question is if this is a Cercophora because there can be a confusion with Podospora. However one-celled spores are discharged from the asci when they are still hyaline and this does not occus with Podospora. Excuses that not all lphotos are in focus but too much pressure on the deck glass will result in breaking off for the two cauda.

Encore un coprophile

Bonsoir à tous Vous serait-il possible de confirmer ma diagnose au sujet d'un petit coprophile? Plusieurs périthèces + ou - immergés au sein d'une crotte de ragondin. Chaque périthèce subglobuleux à pyriforme est doté d'un col coriace. La paroi membraneuse du périthèce est semi transparente laissant entrvoir au microscope son contenu (des asques volumineuses polysporés). A l'état immature les asques sont claviformes pour prendre ensuite l'aspect de sac.garni de spores (128?? 256 ?) (300-350 x 120 130 µm. Les spores en 2 parties comme chez tous les popdospora avec: Une tête sombre 17-18 x 10-11 µm Un pédicelle hyalin ou queue légèrement claviforme 10-11 x 3 µm Des appendices gélatineux (apical et basal) peuvent être parfois perçus. Je songe à Podospora curvicolla. Est-ce bien le cas?? mERCI POUR VOS AVIS

Un Podospora polysporé

Bonsoir à tous Voilà plusieurs jours que je m'attéle à cette espèce que je ne sais comment nommer. Sur crottes de lapin après un bon mois en chambre humide j'ai découvert plusieurs périthèces plus ou moins enchassés dans le substrat et presque parfaitement globuleux à subpyriformes, avec un col noir portant des poils sombres, septés à paroi épaisse, et plutot à sommet obtus. Les asques mesurent de l'ordre de 300 à 370 x 60 - 100 µm polysporés (j'ai la vague impression qu'il ya entre 64 ou 128 spores. Les spores sur asques murs éclatés donnent pour la partie supérieure 20-25 x 13-15 µm et pour le pédicelle 18-20 x 5-6 µm. Des appendices gélatineux semblent bien révèlés lors du montage dans le bleu coton. Je gravite autour de P. setosa ou P. platensis ou encore tout simplement P. Curvicolla mais j'hésite par manque d'expérience Qu'en pensez-vous ? Merci de tenir compte de ma demande.

Unguiculella tityri on Eutypella scoparia

Found on cow dung. Perithecium embedded in the dung whereby only the neck is sticking out. Neck is covered with straight hairs short at the top 130-159 um and longer at the base 500-600 um, both with a width of 4.5-5.5 um, thickwalled 0.9-1.2 um, 5-6 septa hairs constricted but not at the septa. Asci: Only one mature ascus found containing 512 spores 470x160 um with a short stalk. It is difficult to find an ascus still containing spores because most of the time they collaps and counting the spores will be impossible. Spores: 18.5-21.5x11.5-13 um, pedicel 13-15x4.5-5.5 um, upper cauda and lower cauda present. The number of spores are counted by pressing the ascus and spreading the spores, the software is adding a dot and a number to each spore this way counting a great amount of spores is possible (foto-12) and then it's just a matter of counting the end numbers of each overvieuw The cauda seems to consist of two lashes see foto-8 whereby the end of two lashes is visible by the cauda connected to the pedicel. When pressing the deck glass caudas becomes extremely long foto-11 Also by pressing the ascus it looks as if the spores are connected to each other by a string when forced out of the ascus. (foto-10)

Appendages and sheaths

Dear friends The keys of Shoemaker on Ophiobolus and Phaeosphaeria make use of "appendages" (Ophiobolus) and "sheaths" (Phaeosphaeria) for sporefeatures. I usually make my mounts in water and the I never see appendages nor sheaths. Should I use other reagentia to see them? Who can give me advise in this matter? Greetings Jac Gelderblom

Adam Polhorský, 04-05-2016

Hello everyone, microscopy corresponds well with U. tityri, but the host is atypical(?). Could there be another possibility? Asci: MLZ-, crozier+, bi to uni-seriate Spores: 5-7 x 3,5-4 , with few guttules Paraphyses: perhaps 2 types?? majority protruding, coiled or straight, narrowing to the apex others are immersed between asci with rounded apex Hairs: i dont think i observed hairs, could not find them at the margin. Thank you, Adam

Podospora anserina/pauciseta

Found on cow dung. Yesterday I managed to make some photos of P. anserina especially from the pedicel and connected caudae. This is very rare because the pedicel mostly collaps and the caudae easily disconnect from their connection point or they break and will therefore not be (completely)visible. Mirze & Cain did not mention the measurements of the caudae but they happen to be much longer than those of P. pauceiseta as described by Lundqvist. Based on the circular shaped connection of the lateral cauda on the pedicel and the view of the other caudae I assume that all caudae are cylindrical. The pedicel is also much longer than the ones from P. pauciseta. Measured data: Pedicel: 24.6-27.2x 5.0-6.0 um (P. pauciseta 16-18x3.5-5 um) Upper cauda: 115-159x3.8-4.2 um (P. pauciseta 65-90x8-8.5x6.7 um) Secondary cauda at the end of the pedicel 43.0x2.0 (P. pauciseta 75x3-5 um) Two lateral caudae connected to the pedicel 48x3.3 um (P. pauciseta 3-4 caudae 25x2-3 um) All caudae do end in some sort of a tail. Spores: 35-36.7x19-19.5 um (P. pauciseta 35-40x18-19 um) The neck of the perithecium is completely covered with whall thickenings and tuffs of septated hyaline hairs but sometimes only with some single hairs or no hairs at all. I also did find an interesting article (released the 25th of november 2020) about the namechange for P. anserina in Triangularia anserina that can be found on mycokeys. pensoft.net/article/55968/, I can also provide it as a full PDF file.

Bonjour à tous Ci- joint une présentation de ce que j'ai obtenu à partir d'un périthèce prélevé sur crottin de cheval. Ascome de 1700 x 650 µm avec un col 250 x 200 µm. Spores bicellulaires: la grosse colorée (noire) 25 - 28 x 15 - 19 µm ; la petite hyaline (pédicelle) 11 - 12 x 2 - 3 µm.. Bord de la paroi de périthèce avec de courtes écailles ou touffes de poils courts bi- ou tricellulaires. J'ai pensé à Schizothecium squamulosum (=Podospora squamulosa) d'après la taille des des spores. Suis-je dans le vrai ?? Sinon quelqu'un peut-il me préciser l'espèce en question en espérant que le genre est correct.

Arnium

Hello all, I would like to identify a fungus, that I found on rabbit dung. I have observed some features and I think that the fungus belongs to Arnium, but I am not sure. There are also similar genera, par ex. Podospora (without pedicel). Perithecia pyriform 500-600 x 350-400 mcm. The perithecial neck is covered with rigid brown polyseptate isolated hairs, up to 160 mcm long. The outer side of the perithecium is covered with thin brown hairs. The 8-spored, more or less longstalked asci have equilateral biseriate spores. I cannot say, how many germ pores there are. I suppose, that there are 2. I cannot clear 100% this feature. The spores with polar gelatinous caudae (one at each end) appears to be without pedicel. Spore size: (35) 36 – 40 (43) x 20 – 23 (30) mcm. In cotton blue the apical ring of the asci is not visible, I think it is absent. The eccentric caudae are thickwalled, from 50-100 mcm long, but often ruptured, so they appear shorter. It seems, that they have a middle channel (?).The caudae are very difficult to view. Following the Doveri's key I came to Arnium hirtum, on condition that the asco is a Arnium and the asci are without apical ring and the spores have 2 germ pores. Arnium cervinum is described as similar, but it occurs only on cervine dung. I would be very happy for any suggestion how to stain the slide preparation for making visible the shape and form of the caudae and the spore germ pores. Thank you for your help! matthaeus

Sporormiella minutosperma

Found on cow dung. Measurements of the perithecia and asci do not represent the mentioned values in the documentation because it was not a fully mature species. Perithecia: 493x458 um with a neck of 168x162 um; sporadically covered with flexuous, septated hairs 2.0-2.5 um wide; the neck is covered with straight thick walled, constricted, multiple septated and hyaline-tipped hairs 87-132.5x4.3-5.6 um with a wall of 0.8-0.95 um. Ascus: 512 spores; 275x58 um with a stolk of 43.5 um. Spores: 21-25x13-16 um; pedicel 12-16x5.0-6.5 um; upper cauda probably consisting of agglutinated filaments 38.5-40.0x3.4-5.2 um; secondary cauda consisting of two to 4 filaments connected to the side of the pedicel, at first separated but half way agglutinated and finally curved whereby the two main filaments are clearly visible by means of two bright spots. Filaments and the top of the pedicel are covered with granules but they are hard to detect and certainly not with mature spores. Photos 11&12 show the filaments attached to the side of the pedicel and in my opinion they agglutinate halfway. The white spots at the and of the caudea clearly show that two main filaments are present probably surrounded by others. Photo 9 show two small white dots on the pedicel of the most left spore indicating the connection to the pedicel. To me it looks like the agglutinated filaments of the secondary caudea bend down like the pistil of a flower when they curl. The upper caudea do not have that, despite the fact that they are already agglutinated and also do curl at the end. Photo 8 is a negative from the previous one showing the granules at the end of the pedicel and covering the filaments, they are not visible on a normal coloured photo. I used a 40x objective because a 100x objective blurred the photos so the granules were not clearly visible. Joop

Non Asco

I came across this growing on and around some Podospora on sheep dung and although I think it might be a Hyphomycete and I know that is not the purpose of this forum but has anyone come across anything similar. The distinctive multi septate spores are up to 90 x 10.5. Thanks Mal

Melanospora-like mystery

<div>The recent thread between Malcolm Greaves and Paul Cannon re a possible Melanospora species reminded me of this collection, over 2 years ago. Annoyingly I'm not sure whether I kept any material, so it is possible that these images are all the evidence.</div> <div>The perithecia were around 350µm diameter and did not have a neck, but there was a darkened area around the ostiole, associated with some hyaline hyphae (see image). I did not see any asci, so don't know whether they were 4- or 8-spored. The ascospores were limoniform, with, I think, 2 ostioles, one of them more obvious than the other. They measured 18.1-20.1 x 9.8-12µm, and were very finely ornamented with low warts - see photo - this shows the surface, not internal contents. I doubt I would have observed this subtle feature were it not for DIC illumination.</div> <div>The Mycokeys paper on Melanospora and its relatives came out after I had looked at this, so I have now gone through that but it hasn't made things clearer - Melanospora verrucispora is clearly a very different fungus. I don't have access to "A re-evaluation of Melanospora Corda and similar Pyrenomycetes, with a revision of the British species" in Botanical Jounal of the Linnean Society 84(2), February 1982; I suspect that is where Paul described his species.</div> <div>I am not optimistic, but any comments would be interesting.</div> <div>Chris</div>

strange Dothideomycetes?

Hello again, I have recently found another interesting fungus growing on decideous wood (Fagus or Carpinus). I will give you a description of it right here: Fruitbody consisting of clustered pseudothecia (similar to Dothiora ribesia) embedded (partly?) in an unshaped, black stroma 0,8-1,4 mm, which shows grey to darkgrey colors after cutting it; "Pseudothecia" sphaerical, 0,1-0,2 mm, pale brownish, with a protuding ostiolus covered with black hairs. Spores 14-17x5-6 µm, hyalin, pale brownish, 6-9x septate with a few longitudinale septes, in almost all cells with one bigger vakuole, smooth, constricted at septae. Asci 50-60x8-12 µm, with 8 spores in an irregularly biseriate arrangement, short stalked, claviform to cylindrical, IKI- (no reaction). Paraphyses inconsiderable, very tall, hyaline. Hairs 10-14x2,9-4,3 µm, consisting of 1 or 2 cells, dark brown, smooth (reminds of hairs of Podospora-species). What can it be? One more question: is Ellis&Ellis "Microfungi on Land Plants" a book to determine this species? I know about it but I wish to have some critics ;) regards, kazuya

Podospora sp

Bonjour, auriez-vous un avis sur la récolte ci-dssous : Récolte du 31/10/2023, sur crottes d'oie (Anser), en bord de rivière Vienne, commune de Availles Limouzine (86). Périthèce immergé, piriforme, avec col émergent. Corps subglobuleux 550-600 x 430-500 µm, brun ambré sous le microscope, col noirâtre cylindrique 150-200 x 120-150 µm. Péridium à cellules subglobuleuses à polyédriques, avec des poils flexueux bruns vers la base. Présence à la base du col de poils cylindriques courts brun foncé, à sommet arrondi, jusqu'à 23 x 4 µm. Asques fusiformes à base doucement atténuée, avec parfois un bourrelet apical plus ou moins marqué, à paroi épaisse jusqu'à 4 µm, contenant (probablement) 32 spores. Jeunes asques 280 x 45 µm par exemple. Présences de grosses cellules hyalines, globuleuses à utriformes, 32x25 µm par exemple, entre les asques. Spores jeunes hyalines, presque cylindriques. Cellule colorée elliptique à base tronquée, brun olive à la fin, souvent symétrique, (24)25-26(27) x (13,5)14-16 µm. Pore germinatif excentré, de diamètre 1,5 µm. Pédicelle cylindrique à légèrement clavé, 31-33 x 5-6 µm, qui se collapse vite à maturité. Appendice apical presque central, cylindrique, souple, de diamètre 4 µm à la base, à extrémité souvent renflée jusqu'à 8 µm, longueur 25-30(85) µm, plein, à surface finement granuleuse, avec parfois des fines stries transversales. Appendices présents à la base de la cellule colorée, sous forme de petites masses (souvent 3), 5x5µm ou 10x7µm par exemple, parfois à aspect filamenteux/strié. Une petite masse gélatineuse est parfois présente vers le milieu du pédicelle. Tous ces appendices gélatineux fixent le bleu de crésyl. L'aspect des très jeunes spores presque cylindriques et la présence de poils courts bruns à la base du col sont des caractères de la section Rhypophila de Lundqvist. Merci, bonne soirée. Bruno

Found on cow dung. At first I was thinking about S. pulchella but measurements did not cope with the discription in "Revision of Sporormia and Sporormiella" 1972 Ahmed & Cain CJB Vol. 50, 456/457. Interesting was that they only appeared close to or on the surrounding dung of Podospora pyriformis. (photo-1, where you observe the necks of the species next to the ostiole of P. pyriformis bursting out of the dung surface) Perithecia: 173-186 um in diameter, with a neck of 95x40 um. Asci: 8-spored; at first 74-83x8.4-8.85 um; expanding in water 90-100x9.3-9.65 um; with a long stalk. Spores: multi serial; 17-18.5x3.0-3.55 um; 2nd cell has a width of 3.9-4.4 um; end cells longer then mid-cells; transverse septa; straight or slightly curved; with an oblique to diagonal germ slit

Pyrenomycète sur charbonnière (Jugulospora?)

Chers collègues, en mettre en ordre notre place de gril dans notre jardin, j'ai realisé que il est couvert avec des nombreuses colonnies de Anthracobia melaloma. Entre cets Anthracobias, j'ai trouvé un petit Pyrenomycète, noir et da la taille et forme comme je le connais de Pyrenos sur fumier (Podospora e.g.). Je sais que il y a le genre Strattonia, qui pousse sur charbonnières, mais ca ne juste pas. Avec ELLIS & ELLIS je suis arrivé chez Jugulospora rotula, que va assez bien, aussi macro- que microscopiquement. Aussi il est dit de pousser "toujours entre des Anthracobia" .... Ce que ne just pas bien: - Grandeur des spores: J'ai trouvé appr. 22 x 15 µm, dans DENNIS ils sont dites18-19 x 13-14 µm. - Je n'ai pas trouvé un appendix hyaline, qui est obligatoire pour cet espèce et dit d'°etre 2,5-3,5 µm longue. - La surface des spores est dit "marble par des plaques plus foncé" ("covered with darker spots". Comme j'ai observé chez ma collection, ce ne sont pas des taches, mais des dépressions, pour ne pas dire des trous. Ca rappel à un boule de golfe. C'est assez bien a voir dans le foto ajoint (dans Lugol, les asques sont J-). Questions: Est-ce que quelqu'un connait cet Jugulospora rotula et peux dire, si les spores sont comme ca? Si ce n'est pas Jugulospora, une idée qu'est-ce que ce? Cets spores me semblent assez caracteristique! Merci beaucoup et amicalement, Andreas

Sur crotte de lapin

Les exemplaires ne sont probablement encore complètement à maturité. Sur crotte de lapin en chambre humide. J'en ai quand-même prélevé un pour étude. Ressemble à un Xylaria multiforme mais de moins de 1mm. Les asques sont situées vers la base, 8 spores, parfois les parois sont "collées" aux spores. Spores lisses, ou parfois paraissant très finement granuleuses avant d'être à maturité. Certaines présentent une gangue les entourant. Paraphyses septées, presque droites. Spores (35,8) 36,7 -38,7- 40,6 (41,9) × (18,4) 18,7 -19,6- 20,6 (21,1) µm Q = 1,9 -2,0- 2,1 (2,2) Je n'ai aucune idée pour le moment...

Cercophora citrina Lundqvist

Hi forum, I need a good description of this species. Pictures of microscopical and macroscopical features would be nice. Alain

Spumatoria longicollis

Found on cow dung. A different find than the one from 291112 which was on horse dung, but it is in the same area. Cow dung is from Galloway cattle, the horse dung was from Iceland pony's. Finding is confirmed by David Malloch. The neck is covered by longitudinal hyphea, 293x25.5 um, the beak constist of the same clustered hyphea The perithecia: 112.5 um in diameter. No asci found yet, but the species are abundently present so I can wait till they are ripe enough. Spore measurement 24.57x5.6 um on a single spore, containing one septa and oil drops. Immature spores filled with numerous small oil drops.

Cercophora-Inmersiella

Cher tous: J'ai trouvé sur bois tres degradée ces petits peritheces, non inmergées, tous ils couverts de poils hyalines jusqu'a l'ostiole. La morphologie des spores et ses changes me parlent de Cercophora caudata (= Inmersiella c.). Connaisez vous s'il est possible cette couveture blanche dans cet spece? Je n'ai trouvé dans la literature acune reference a cet caracter. Merci en avancé Enrique
