White asco on wood

Hi to everybodyI'd like to know your opinion about these totally white ascomata, not yellowish nor reddening, small (up to 1.4 mm in diam.), gregarious, shortly stipitate by a stout and short stipe. The margin is glabrous an inrolled and the excipulum is white and pubescent.
The ascomata grow on Betula alba wet wood at 1600 m of altitude.
The asci seems to be IKI very faintly blue, 8-spored and they have croziers. Paraphyses have long cylindrical and refringent vacuoles. Ectal excipulum with textura angularis with many short polymorfic indiferenciate hairs. No basal blue reaction with IKI or Mlz.
I can't see a clearly textura oblita in the excipulum and because of it I cannot say that my fungus is close to Bisporella subpallida.
What do you think?
Many thanks again

Re : White asco on wood
Yes, this is Calycina languida. There is only one thing: the type in the Karsten Herbarium is without croziers. My collections are partly without, but others with croziers. Otherwise I see hardly any difference. The apical ring is RB in both (blue then +/- dirty red).
It is a typical montane to subalpine-boreal species and grows on Fagus, Betula and Alnus viridis.
