On Vaccinium leaves

Hi to everybody


This fungus with small (up to 0.8 mm), turbinate, shortly and narrowly stipitate, gregarious apothecia with pale yellowish hymenium and no blackish stipe was found on Vaccinium uliginosum leaves at 1700 m of altitude.


The excipulum is made by roundish cells that make short, septate, obtuse hairs at the flanks. Marginal cells, as the paraphyses, are filled with many small roundish VBs that stain in CRb. Asci 120-141 x 13-14, IKI negative even after KOH-pret., with no croziers.


I don't know a good genus for it. Maybe a Phaeohelotium or Hymenoscyphus species?  


Thanks again for your help

Re : On Vaccinium leaves
Hi Enrique!
I imagine it is something such as Phaeohelotium epiphyllum but not sure. inamyloid asci may occur there but the oil drops in the spores are a bit small. 
A I overlooked the absence of croziers! Well then I have no spontaneous idea.
