I found this specimen growing on a dead leaf, and some mycologists think is a Thamnomyces, but the references or photos are very limited. May be any can help.? Spores round, hialine, very small, 2 - 3 microns.
Thanks

Re : Thamnomyces ?
Hi Eduardo!
Beautiful, I regret there are no such things in Poland...
Even if it is Thamnomyces, it seems that you have anamorphic stage here (although Dictionary of the Fungi gives Nodulisporium as an anamorph, and this looks totally different), or at least the spores you took in the prep slide belong to the anamorph.
You should make a prep slide from black perithecia, but I'm not sure if there are any?
Indeed not much literature, but do you know this? - "Chemotaxonomic and phylogenetic studies of Thamnomyces"
(Xylariaceae) ?http://www.springerlink.com/content/v47n738410tg62k4/fulltext.pdf?
But still, with anamorph only not much can be done, I'm afraid...
Best,
Mateusz

Re : Thamnomyces ?
Yes...agree....this specimen dont have peritecias...but dont have any reference about a fungi with this characteristics...

Re : Thamnomyces ?
I examined a specimen three days later, and observe a formation of ascoma-like structures in the middle of filament, now lokks some kind of Xylaria...no asci yet.

Re : Thamnomyces ?
Hi Eduardo!
Not necessarily Xylaria, still can be Thamnomyces, you should make a cross section through a stroma to see if it is white inside (Xylaria). In this paper I have sent a link to (by the way, do you have access to it? I'm uploading in case you don't), they write that asci even in fresh specimens are difficult to observe (but persistent in Xylaria).
I'm off this week, but when I return I will try to gather literature about all Thamnomyces and Thamnomyces-like Xylarias, and we'll try to work further on this specimen.
Best,
Mateusz

Re : Thamnomyces ?
To me it is no more than an immature species of a foliicolous Xyalria: It belongs, judging by the peculiar peg-like anamorphic structures, to the Xylaria phyllocharis-aristata complex.
And see: Revista Mexicana de Micología. 1997. Vol. 13. pp. 58-69.

Re : Thamnomyces ?
I fully comply with the comments made by Filipe. It is certainly one of the soft xylarias. Several species with this kind of anamorph has been described including X. melicearum (not this one). Xylaria sometimes have a black, yellow or brown entostroma, so the the colour is not enough. Species of Thamnomyces are highly carbonized and hence very brittle in dried condition.

Hello All!
So the riddle is resolved!
Dear Felipe, is it posible to obtain that paper from you? It seems that the webpage of Revista doesn't host this article...

Re : Thamnomyces ?
Dear Mateusz: Unfortunately I can not answer your request, now I am far away from where my literature is. Ask Thomas for the paper, he is an extraordinary kind, helpful and brilliant mycologist.
Also Check: Mycotaxon 31 (1): 103-153. 1987.

Dear Felipe!
Thank you for the tip! These Xylarias and Xylaria-like fungi appear more and more fascinating for me!

Re : Thamnomyces ?
Dear Thomas!
So maybe you can help with obtaining Felipe's paper on Mexican Xylarias?
Or maybe any of you, Dear Friends, is a happy owner of this publication and could share it here?
Best wishes,
Mateusz
