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.?

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