Hymenoscyphus-like with fusiform spores
Juuso Äikäs, 17-07-2020 14:23
I found these growing on a fallen, decorticated branch (probably deciduous) at the bottom of a forest stream. 

Asci with croziers, IKI negative. 

Spores:

(12.1) 12.8 - 15.7 (16.9) × (5.4) 5.6 - 6 (6.1) µm
Q = (2) 2.2 - 2.6 (3.1) ; N = 15
Me = 14 × 5.8 µm ; Qe = 2.4

What might this be?

Re : Hymenoscyphus-like with fusiform spores
This must be Hymenoscyphus phiala, a name that is not clear at all, but the species is. I know it only from Alnus, and your branch looks like this as there are false radial rays that cause a slight slit-like depression on the wood surface.

I have it in my Cudoniella folder.

Re : Hymenoscyphus-like with fusiform spores
Thank you, that seems to fit quite well. Once again a species that doesn't seem to be on the Finnish species list. 

There was Alnus incana growing at the place, so there's a good chance that's the substrate. I checked the pores and looks like hardwood to me, and I suspect the orange layer might speak for Alnus.

Re : Hymenoscyphus-like with fusiform spores
The pores in radial rays tell for a Betulaceae. You can check in radial section the dense ladders in the vessels typical of Alnus.
