On Vaccinium uliginosum leaves

Hello forum,

these subsessile ones are about 0,1-0,2 mm wide.
The spores are about 10-14x2-2,5.
Asci are about 35-50x5-7, IKI blue, hymenoscyphus type, I suppose.
Paraphyses are about 2-3 wide and septate.

So, can this be a Hymenoscyphus species or something else?

Re : On Vaccinium uliginosum leaves
Hi Marja

the apical ring is more of the Calycina-Type and I believe this is Calycellina leucella.

Hi Zotto,

Thank you, you must be right.

C. leucella is common and much varied on the leaves of broadleaved trees and seemingly on the leaves of berries, too. I have not yet met it ealier this year and do not remember the microscophy. New substrate for me to that species anyway.
