Hi everyone,I found this white, star-shaped asco on a Fagus grandifolia leaf in Quebec, Canada.
Spores: 15–16.6 × 3.5–4.3 µm
Asci: IKI+
Here’s the iNat link with photos and microscopy:
Any idea what it could be?
Thanks!

Re : White asco on Fagus grandifolia leaf
I do not understand the macroscopy. Are the apos stalked or sessile and what about the toothed receptacle? What are the teeth composed of?
Microscopy recalls H. caudatus agg.

Re : White asco on Fagus grandifolia leaf
Yes, the apothecia were short-stalked. I think the "star shape" is just an unusual shape; next to them were some other apothecia with a regular form like other Hymenoscyphus. The teeth were just like the rest of the hymenium.
Thanks Zotto
