Hello,I found this species on heracleum. Size 0,2/0,4mmx0,1/0,2mm, asci 8-spored 47/64x16/21, spores 13/18x6/8µm. Textura angularis and the paraphyses are absent in this stage
Any suggestions?
regards,
Ralph

Some more microscopic pictures ...
Size of fruiting body is also corrected

I suppose this is a bitunicate ascomycete. The spore shape with the strong constriction and broader upper part suggests this, also the wonderful ohoto of living asci with the apical thickening lets me think of a "jack-in-the-box"-mechanism.
I have no experience with such fungi. Maybe this is rather a pyrenomycete.

Hi all,
I have no idea right now, though I wonder if I haven't seen something similar. There's a young ascus on a photo clearly suggesting a Dothideomycetes, a bitunicate.
You gotta search among Didymella, Mycosphaerella, Venturia and other didymosporous Dothideomycetes. I'll try to have a look tomorrow.
Cheers - LUC.

I have a better idea: just check a bit Psiloglonium and related genera, here for example? Looks like the ascomes are hysteriothecia's.
There are genera with Didymella-like didymospores:
http://studiesinmycology.org/content/64/1/49.full.pdf+html
My two cents.
Cheers - LUC
EDIT: from informal email exchanges, it appears Psiloglonium have a much thicker peridium, so scrap that.
I fear that's one of those many species which need further samples to be studied and sequenced by professional mycologists and labs :/

Hello Luc,
Thanks for the info. I will have a look at this genus tonight.
PS I saw you're from Belgium. Where. i from Vossem (Tervuren)

You're welcome, Ralph.

Hi friends,
here are further results of the "lophodermium-like" species from Ralph. It is not a Dothideomycete, but I am thinking of Lecanoromycetes.
I do not have an idea until now. But I will study more literature to find it out.

björn
