Gernot FriebesHi,I need your help with some black dots on a lich
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
This is Phaeohelotium geogenum (= Hymenoscyphus geogenus).
But the asci should have a small blue apical ring in IKI.
