... on stem of Peucedanum ostruthium in (sub)-alpine zone. The asci bear croziers and are IKI-hemiamyloid. The spores are somewhat fusiform and are ca. 10-15/2-3 (3,5) µm large, they contain few oil. The hairs remind a bit of Olla - thick-walled with lumen, but I know no species with such a color (?). Chaetionaevia petasitis seems to have similar spores and similar-shaped hairs. Who has a further hint?Yours, Lothar
