Brown clusters on Sorbus branch
Juuso Äikäs, 06-11-2022 13:25
Clusters of these brown ascomata were growing on a thin, fallen branch of Sorbus aucuparia.

Asci with croziers, IKI+ dirty red - purple. Paraphyses cylindrical, with small low-refractive guttules. Margin cells with a roughened, hyaline tip. Spores globose, diameter 2.6 - 3.2 µm.

I'm not sure, but I get a feeling that this might be a lichen, rather than a pure ascomycete. Any thoughts?

Hello Juuso Äikäs!

This is Hyphodiscus theiodeus, grows on or with old Peniophora cinerea.
