Re : Pyrenomycet on Corylus avellana.
Hi, 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

Re : Pyrenomycet on Corylus avellana.
I agree with Gernot, it might be H. fuscum but the spores you show have a conical cellular appendage at base, which is unknown in Hypoxylon.Make sure they come from the stromata you show on pics 1-2.
Ascospores of H. fuscum are also distinctive in having a sigmoid, not straight germ slit, please take photos at higher magnification to illustrate this.

Re : Pyrenomycet on Corylus avellana.
The spores came from my pictures 1 and2.
I know H. fuscum well, but this has another shape.
Thank you both for help.
