Using Huhtinen's 1989 key this is the best fit I got but would appreciate a second opinion.
The apos are up to 0.4mm wide. Asci arising from croziers, ascus pores amyloid.
Spore measurements: 7.7-9.4 × 2.5-2.9 µm (N = 5).

Re : Hyaloscypha albohyalina var. albohyalina?
A second opinion could be H. fuckelii var. fuckelii. By memory I know albohylalina with larger spores with larger guttules.

Re : Hyaloscypha albohyalina var. albohyalina?
Yeah, the spores cast a doubt. They didn't have much oil and are a bit small but would fit in the range. And there weren't many of them (maybe a bit unripe?). Fuckelii max. width was about 2.5 microns and would have a low oil content if I remeber correctly. Maybe I'll try to find more spores and this would be clearer.

Re : Hyaloscypha albohyalina var. albohyalina?
my memory is not fully sure if Huhtinen uses living in his key or dead spores which are smaller.
