Re : Hyaloscypha?
I imagine this is Olla transiens. The ascus base should be without croziers.

Re : Hyaloscypha?
That would be Olla transiens. The longer the hair the shorter the "glassy" part at the apex. Shorter/developing hairs have more glassiness. It's also dextrinoid. Sometimes the glassiness is barely visible in H2O mount, then MLZ/IKI helps. The spore shape looks like a foot print. There are two somewhat different sequences in Genbank. Both are Olla, but maybe not the same species. I've been trying to figure it out, but I havent got very clever yet. There's some older discussion on this matter, (this Forum), try searching for Olla.
