Ascomycete on oak cupules
Edit Szilvásy, 30-09-2013 22:59
Edit SzilvásyHi 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

Hi Edit

This is Phaeohelotium geogenum (= Hymenoscyphus geogenus).

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