Hi Maren,
this reminds me on Exarmidium diaphanum (see my attached pdf).

Re : Unknown pyreno
Yes Martin it is probably Exarmidium inclusum, a species we had on the forum already, and which has larger spores than your diaphanum, as you have pointed out. But I cannot remember to have ever consultued the literature, only I have images a couple of collections.
I have it in Xylariomycetidae, Hyponectriaceae

Re : Unknown pyreno
Yes Zotto,
I forgot this discussion. Meanwhile I do have Aptroot 1998. He synonymizes E. diaphanum with E. inclusum.

Re : Unknown pyreno
Oh yes, so this makes things easier :-) Maybe the fungus is really variable in spore size, and I noted it can occur also with much more opened hymenium half as a discomycete.

Re : Unknown pyreno
Hi Martin, hi Zotto
thank you very much. It is E. inclusum.
I checked on the spores size again. There isn't any difference to my first measurement. The largest one is 19,5 x 7 µm, the smallest 17 x 7 µm.
