Hello.I would like a name on this.
Spores 15x6 my.
Asci 150x7
Greetings, Per
it looks like a Hypoxylon, e.g. H. fuscum, which is very common on Corylus. If you can, please put a piece of the stroma in a drop of KOH and observe the KOH-extractable pigments. For further infos also see here: http://pyrenomycetes.free.fr/hypoxylon/html/Hypoxylon_fuscum.htm
Best wishes,
Gernot
Ascospores of H. fuscum are also distinctive in having a sigmoid, not straight germ slit, please take photos at higher magnification to illustrate this.
Jacques
I know H. fuscum well, but this has another shape.
Thank you both for help.
Per.
