Ascomycete on oak cupules

Edit Szilvásy, 30-09-2013 22:59

Hi all,

I've found this ascomycete on oak cupules. Apothecia 2-8 mm across.

Spores ellipsoid, hyaline, 24-5 µm

J-negative (Lugol)

Does anyone have an idea what this might be?

Thanks in advance

Regards, Edit

Re : Ascomycete on oak cupules

Hi Edit

This is Phaeohelotium geogenum (= Hymenoscyphus geogenus).

But the asci should have a small blue apical ring in IKI.
