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.
regards,
björn
