Hello! I found this species that resembles Delitsc
may I ask you for help ? I would need some idea or opinion.
Found on dead wood Fraxinus excelsior. I don't know how the amorphous stage of Hymenoscyphus fraxineus (Chalara fraxinea) actually looks macroscopic. The fruiting body is fragile, and contains structures that are pictured. Found both in January but also in September

have you tried (macro) reaction of the stroma(?) in KOH? To me it looks a bit like a germinating Hypoxylon.Â
Tori
Slightly yellow color reaction of "stroma" with 10% KOH. But I've also never not seen spore chaining with Hypoxylon sp. It looks more like chlamydiospores that produce conidia

Pavol
compare with Xylohypha nigrescens.
best regards,
Thorben
Thank you, it looks like that's it
Sincerely
Pavol
