Hello,I have identified this fungus as Hymenoscyph
Helotiales on Betula leaf
Juuso Äikäs,

Asci 8-spored, IKI+(b). The asci have prominent basal protuberances, but seem to lack proper croziers.
There were some cylindrical cells without contents that might be paraphyses or marginal cells.
The excipulum seems to be of textura porrecta.
Spores:
9.6 - 11.89 (11.9) × (2.5) 2.53 - 3.28 (3.3) µm
Q = 3 - 4.1 ; N = 5
Me = 10.2 × 2.8 µm ; Qe = 3.6

Re : Helotiales on Betula leaf
I imagined Hyaloscypha fuscostipitata but that has definitely smaller spores and particularly strongly tapering hairs, also a dark base. And you are right: the ascus protuberance does not fuse. What seems to be paraphyses is not clearly alive, are you sure that the fungus has no VBs?

Re : Helotiales on Betula leaf
There are globose bodies with that colour which could point to multiguttulate VBs, but not sure.
