Sur une pierre recouverte de mousse (forêt de montagne à 2'000m), périthèces piriformes avec une petite papille, 0.15 - 0.25 mm de diamètre, ascus bituniqué, avec huit pores, IKI-, 120 - 150 x 20 - 25 µm, spores verruqueuses, hyalines, à deux cellules, 20 - 32 x 8 - 10 µm. Ces caractéristiques me font penser à B. popei, sauf que mes spores sont plus larges. Qu'en pensez-vous ? Merci d'avance pour vos avis.

Re : Bryostroma
Dear Elisabeth,
Excellent find and documentation as always. This does indeed seem to be a Bryostroma. It will be important to identify the host. The type species, B. racomitrii, is possible, though it should have a mixture of 8- and 4-spored asci. B. axillare is also close. All the known species are in the B. popei paper key.
But there are likely many undescribed species around. I have one on Racomitrium fasciculare with 4-spored asci but much smaller spores than B. racomitrii, so it must be something new. But the collection was too small!
All the best,
George
