.. on Alnus alnobetula, 16.7.24.When finding I first thought of a Trichoderma teleomorph similar to T. lixii. When cutting I got the first surprise when I saw the light-colored flesh. The flesh, by the way, was rather soft (more like in Trichoderma than in typical pyrenomycetes). Under the microscope I found polysporous asci with light brown allantoid spores with size about 5-6,5/0,8-1 µm - similar to Eutypella and similar genera. I do not have a hint - who has one?
Best regards, Lothar
(P.S. I once before had a similar experience - thinking of a soft-fleshed black Trichoderma spec. but "becoming" a fully different pyrenomycete. It was in Portugal and there was no hint - is it today?:

Re : pyrenomycete from French Alps
Hello Angelo,
thank you for your contribution. ...
Yes, this seems probable from the microscopy.
But I never found such a soft-fleshed specimen before - and no specimen that looked this way macroscopically. Maybe it can be determined still.

Re : pyrenomycete from French Alps
If it is a Diatrypella it can only be D. tocciaeana - or a new species.
I still am hesitating, because I know Diatrypella as quite hard fungi, fully immersed and usually old and destroyed when becoming free.
Hm ...
