Hymenoscyphus on Betula leaf

Juuso Äikäs, 29-09-2022 17:25

A finding from a couple days ago: a few white Hymenoscyphus fruitbodies were growing on a fallen, decaying Betula leaf amid Sphagnum in a boggy forest.

Asci 8-spored, without croziers, IKI+ blue. Paraphyses cylindrical, with medium sized round VBs. Ectal excipulum of textura prismatica. The spores measure 14.5 - 18 × 4.8 - 5.2 µm and are without contents (uninucleate?).

Any thoughts?
