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?

Well documented but I have no idea at the moment. Would need to scroll my folders.

Re : Hymenoscyphus on Betula leaf
Ok, I'll search there later. Any idea what folder this might belong to? Hymenoscyphus s.str.?

Re : Hymenoscyphus on Betula leaf
Hei,

muistankohan vuosien takaa. Olisiko H. phyllogenus valkoinen lehdillä ja yleisempi epiphyllys on taas keltainen. Onhan niitä tosin muitakin...

Terkkui: Marja

Indeed, H. phyllogenus is a very good idea!! Thanks Marja.
