Re : Fuscolachnum sp.
Hi Nina,
I agree with Fuscolachnum although te very short hairs intermixed on the excuipulum I did not see. It seems to be a mix of species. F. inopinatum has the stipitate fruitbodies and a cryptogamic host, F. dumorum the exceeding lanceolate paraphyses. So another riddle from Siberia

cheers,
Stip

Re : Fuscolachnum sp.
Great collection! F. dumorum I believe is a Brunnipila, but this one certainly not.

No idea, but Fuscolachnum I agree.
