Little yellowish discs on Picea abies

Juuso Äikäs, 21-04-2018 19:02

Found these a few days ago growing on a well-rotted part of a Picea abies tree trunk. The largest ones are around 0.5 mm wide. Spores fusoid, 5.5-6.5 x 2.5-3 u, Q=2.1-2.4. Eight spores per ascus. Asci meauring around 35x5 u, paraphyses cylindrical or so, septate. Any thoughts? I have no clue.

Re : Little yellowish discs on Picea abies

This is difficult when not seeing free spores, paraphyses, excipulum, ?marginal hairs.
