Hello together

on saturday we found this Lachnum ? on hardwood maybe Fraxinus excelsior, in a forest near to a river.

The spores have no oil content. The spores messuraments are on the photo /(8).

The Ascis are iki-postive (blue) and 40-55 x 4,5-5,0.

The paraphyses are 55-60 x 2-2,5,.

The hairs have the same length but are 5 thick.

The photos was made by my mushroomfriend Gerhard Jenk .

Do anyone no the species ?

Greetings,Eike

Re : Lachnum sp.
Hallo Eike

the strong red-brown colour change of the disc could mean that the paraphyses and also hairs were multiguttulate when alive. Do you have the sample still fresh?

Important is als the ascus base, i cannot clearly see it. Posibly croziersa are absent. Then it could be Lachnum brevipilosum.
