Re:White ascomycete on alnus bark
And strange paraphyses. Microfotos from coloured specimen.
Spores something like 7-10x2-3 and asci 30-40x7-10.
And I've got no idea even of the genus...

Hi Marja

A Hyaloscypha for sure, but without IKI reaction of ascus apex and croziers you have no chance to identify the species.

Thanks Zotto,.
I started from the hairs etc. I'll continue with this tomorrow, if it fits to my schedule ;)

Re:White ascomycete on alnus bark
No ascus reaction in MLZ, but I've got severe problems on seeing the structures in the base of asci.
Anyway H. quercicola seems to be one option (eventhough out of the borders of it's ealier collections in Finland). I'll look for others by sending a specimen tor Mr. Huhtinen ;)
