Hi again,I found this specimen on very wet decidious wood. Perithecia very small, with brown septate hairs on the outside 100 x 4 µm, with roots, on a subiculum.
Spores hyaline, up to 7-septate, (40-57) 49,33 x 3,5 (3-4) µm, Asci 77-86x9-10 µm, IKl negative.
I'm greatful for a genus.
Thank you
Regards, Maren

Re : Pyreno on wet wood
Hi MAren,
what about Tubeufia cerea? Rossman 1987 describes the species as "rarely with hairs". Your species rather belongs to the genus, and I have tried two Tubeufia keys without success. There are similar genera like Wentiomyces, Acanthostigmina, Acanthostigmella and others with quite different microscopical features.

björn
