Thank you mycowalt. You are right. Both Index Fungorum and MycoBank have H. flagellum as a synonym and H. alpestre Pers.1825 as a valid name. I followed Krieglsteiner (2000) Ref.:(1), who still has the opposite.

Abies alba almost for sure

I talked with Mr. Igor Mlekuž, forester in chief in this region about the possibility that this large but quite rotten log of this observation is Abies alba. He considers this as almost certain. Planina Lepoč region is an (although unofficial) reserve for Abies alba. I didn’t notice this when I photographed the fungus. Stands of Abies alba suffered a lot of damage during last decades in Slovenia. Big and still alive trees became almost a rare observation otherwise. Note also that the same log is infected by Multiclavula mucida.
