Lachnum on fallen branch

These I found on Sunday, growing in a moist depression on a decorticated piece of fallen branch.
Asci without croziers, but many with a basal protuberance. Hairs mostly moderately swollen at the apex, with VBs. Paraphyses also with VBs. I only found a few free spores, but they seemed mature and measured 9.2 - 10.1 × 2.1 - 2.4 µm.
I think this could be either L. brevipilosum or L. pudibundum, but I'm not sure which one...

Re : Lachnum on fallen branch
Hi Juuso,
I collected what I regarded to be good pudibundum from dead wood of Crataegus and the apothecia readily discoloured reddish-brown.
Best wishes,
Charles.

Re : Lachnum on fallen branch
Thanks for the reply. I tried squashing a few apos and they turned brown, maybe a little reddish as well. But I think the redding is a quality shared by all Lachnums with VBs, if I'm not mistaken.

Re : Lachnum on fallen branch
This needs more mature apothecia. Good would also to know be the substrate. In mature L. pudibundum the paraphyses protrude by around 10-15 µm, not so in brevipilosum.
Yes, only species with VBs turn reddish-brownish.

Re : Lachnum on fallen branch
Ok, thanks. I'll see if I can keep the sample alive for a while.
