Another Lachnum for identification
Jan Knuiman, 30-06-2018 14:36
Growing on a rotten twig of a broadleaf tree (Salix, Populus, Betula) in a moist environment. This one grew very close to that of my previous topic on Lachnum (29-06-2018).
Cup diameter: max 1 mm.
Stipe height: 0.5-1.0 mm.
Spores: 6.5-9.5 x 1.4-2.4 µm.
Paraphyses: sometimes with a swollen part and protruding the asci by 20 -25 µm. Width: 3.0-7.5 µm.
Hairs: with septa and a maximum length of 60 µm.
Crouziers: I would guess yes.

What Lachnum species could this be?

Re : Another Lachnum for identification
Croziers are cleary visible on your beforelast photo. I guess again L. pubescens. L. subvirgineum has longer, more capitate hairs

Re : Another Lachnum for identification
I have a folder "pubescens cf., salicis, Salix" on my homepage which includes samples on Salix (but the type of L. pubescens was also on Salix and might be the same).

Salix and Populus are not easy to distinguish from the wood anatomy, but Betula is quite different.
