I have no experience with such fungi. Maybe this is rather a pyrenomycete.

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.
There are genera with Didymella-like didymospores:

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 :/
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)

I'm from Roche-à-Frêne, Manhay, province Luxembourg, and I'm active member in the Mycologues du Luxembourg Belge, Société Botanique de Liège (mycology section) and AMFB. And some French societies.
More off-forum.
Cheers - LUC.
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.
regards,
björn
