Hyaloscypha albohyalina var. albohyalina?

I visited a small swamp and found these growing on a fallen Betula trunk. 

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.

my memory is not fully sure if Huhtinen uses living in his key or dead spores which are smaller.
