Re : Trichopeziza (?) on Ulmus
I assume the wood was lying in wet mud, right?
The hairs must be rather narrow, about 50-75 µm long, tapering. The apical ing must react blue in Lugol (finally dirty red when concentrated). Absent croziers is correct.
The apos are much smaller than 1 mm?
And look: the paraphyses are quite narrow an filiform, very unlke Trichopeziza. Also I think the ectal excipulum is not of globulosa.
Amicodisca virella (= brdensis).

Re : Trichopeziza (?) on Ulmus
I have no information about how the wood was lying. I will check if the finder remembers. Yes, the apothecia are very small.
I will check the Lugol reaction and the ectal excipulum.
Thanks a lot!

Re : Trichopeziza (?) on Ulmus
Looks almost a bit reddish, this which is typical.
Well I see isodiametric cells but a good idea is only obtained in a section.
