Lachnum or Dasyscyphella?
Pavel Jiracek, 16-03-2025 19:17
Another find on a piece of Quercus Wood in Scotland. The spores were 7-9  x 1.5-2 microns and there was a bit of brown discoloration on some of the fruit bodies. Some of the hairs have smooth tops, some don't.
Any advice would be greatly appreciated, thanks.

Hi Pavel, 
It seems that the tip of marginal hairs are smooth , at least the last cell. 

As seen very often on the underside of Quercus logs , Dasyscyphella nivea could be the species you have collected . 

Amitiés. Michel

Re : Lachnum or Dasyscyphella?
I suspected this species but was not sure. I also dismissed L.virgeneum since there doesn't seem to be any lanceolate paraphyses.
Thanks Michel
Best wishes Pavel
