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.

Re : Another Lachnum for identification
Dear Jan

I would like to upload your two sequences for an article on Lachnum in Boletus. Did you receive my mail?

As for LP1 I guess the branch is about 10 mm thick, not 3 mm as I have noted.

The collection data are complete, but I need the institute where Jorinde Nuytinck works.

It should be the Naturalis Biodiversity Center in Leiden.

I think I will write her too.
