Hans-Otto BaralOn the ascomeeting in St.-Jean-la-Vetre (Auvergne), Piotr Perz found this nice disco (only 2 apothecia).

On bark of a 9 mm thick dead Picea branch, 1.5 m above ground, corticated, soc. O. euonymi. Asci IKI-. Sp. *18-22 x (6.5-)7-7.7(-8.2) µm (excl. gel), gel sheath ejected 3-5 µm thick.

The species reminds a bit of Tryblidiopsis pinastri, especially because of the gel sheath around the spores. The dead spores are not constricted at the septa, the living ones strongly so.

Anybody an idea?
