Re:Pleosporales on Quercus branch
If the ascomata are soft-textured, this may be a species of Acanthostigma.

Re:Pleosporales on Quercus branch
Hi Zotto,
I agree with Amy it should be an Acanthostigma, and ascospores match well those of A. minutum (Fuckel) Sacc. I repeatedly collected this fungus growing gregarious on rotten water-soaked wood, which is different from your collection, but details on its ecology are still to gather.

Re:Pleosporales on Quercus branch
Dear Amy and Jacques
many thanks for your identification. Yes, the peridium is quite soft. The branch was in ca. 1-2 m above ground at a S-exposed edge of a forest, and all ascos on it are strongly xerotolerant. I rehydrated the branch 4 days after I collected it during dry weather, so also the Acanthostigma is well xerotolerant.
Is there any description in Reblova & Barr 2000? Jacques, do you have a documentation of the species?

Re:Pleosporales on Quercus branch
Hi Zotto,
so it makes a taxon adapted to a wide range of environmental conditions.
I attach the photos of the key and the description of A. minutum by Réblova 2000.
Cheers,
Jacques

Re:Pleosporales on Quercus branch
Hi Jacques
thanks, the description actually fits very well in most points. Septal number in the description is exactly as mine, also spore size and shape is wonderful. No details on the water relations of the substrate are given, regrettably. Interesting the Helicomyces anamorph, I will look again, hoping to find some perithecia left.
