What Lachnum species could this be?
Jan Knuiman, 29-06-2018 16:03
Growing on a rotten twig of a broadleaf tree (Salix, Populus, Betula) in a moist environment. 
Cup diameter: 1-2 mm.
Stipe height: 0.5-1.0 mm.
Spores: 6.0-9.0 x 1.6-2.4 µm.
Paraphyses: with 1-4 septa and protruding the asci by 20 -25 µm.
Hairs: with septa and a maximum length of 70 µm.
Crouziers: not seen.

What Lachnum species could this be?

Not sure with the absence of croziers, I assume they are with, but it is not clearly seen.

I have no clear idea. It could be of the L. pygmaeum complex, or near L. pubescens. Did you measure the width of the paraphyses?

Bonjour Jan,

Looking at your images 7 and 8, I would decide for the presence of croziers And as paraphyses are whithout obvious VBs, most of characters could match L. impudicum (but for the paraphyses rather short overtaking ).

I do not quite recognize L. pygmaeum here .

Amitiés

Hi Michel
I think the paraphyses are also too wide for L. impudicum, apart from the strong protrusion. 

Also the spores are too simple, L. impudicum is often fusoid-clavate and a little inflated. in the upper third.

L. impudicum is a winter species, while L. pubescens was found during summer.

Re : What Lachnum species could this be?
Thanks Zotto and MIchel for your comments. I measured the width of the paraphyses and on average it is 3.9-4.5 µm. Could I measure other features that may be helpful in identifying it?

*3.5-4.5 µm wide paraphyses and spores 4.3-7.5 x 1.9-2.1 µm I have noted for L. pubescens, occurring Jun-Oct. So this species should be considered. I agree that L. pygmaeum is different and usually with a yellow hymenium.
