Hyaloscyphaceae on Betula
Juuso Äikäs, 11-05-2020 19:30
I photographed these a couple weeks ago or so. They grew on a well-decayed piece of Betula sp. I kept the sample in the fridge for some time but now it has decayed away. There isn't a huge amount of data but perhaps at least the genus might be told? 

The spores measure ca. 7-9 x 2 microns, asci pores seemed faintly amyloid. I didn't manage to find any outer hairs.

Re : Hyaloscyphaceae on Betula
A nice hyaline fungus. But atleast I am only guessing and actually... I can't come up with a good one. Not completely sure if this belongs to Hyaloscyphaceae. These anonymous ones dont all belong there.  In the macro I think there are something resembling hairs on the flanks, but not many and probably not easy to catch in the scope. Nothing on the rim, no hairs there.
