Hi Thierry,
It seems that the last cells of the hairs you show are smooth , which would rather match Dasyscyphella intead of LAchnum
Or am I wrong ?
AmitiésMichel

Re : Lachnum virgineum ?
Hi Michel
I think you are right. New observations point in your direction. What species are you thinking of? I saw that there was a castaneicola species.
PS: I am looking for a key to determining the genera of felted or hairy inoperculate ascomycetes. Is there one?

Re : Lachnum virgineum ?
Ain Raitviir's key which takes into account the length of the last article of the hair and the length of the spores leads to D. nivea.

Re : Lachnum virgineum ?
D. nivea is a common species through all winter and can be found nearly systematically on lower faces of Quercus stumps or other hardwood.

Re : Lachnum virgineum ?
Hi Thierry,
What various authors consider to be Lachnum virgineum consists genetically of 5 species, as can be seen in a small section of the ITS1 (-> screenshot of an ailgnment below).
What Lachnum virgineum really is cannot be identified genetically either, because the first description of Lachnum virgineum (Batsch) P. Karst. (1871) is too old to be sequenced.
