Lachnum on grass
Anna Klos, 04-09-2022 09:35
Goodmorning, this is the first time on this forum, so if I can do better, you are free to correct me.

I think this is either L. tenuissimum (= in the Netherlands also L. pudicellum), L. controversum or L. carneolum.

Studied al long time, but can not find a determining factors between them.

With short stalk, becoming red aging.

Spores: (7,2) 8,64-10,08 (11,52) x 1,4-1,8 mu
Parafyses: with (yellow?) guttules
Hairs: capitate, with (yellow) guttules in the lower part, up to 100mu
Asci: Always looking for croziers, but having difficulties finding them

Is this enough information for deciding wich one it could be?

Kind regards, Anna

Re : Lachnum on grass
Hi,

I have one finding of L. pudicellum/tenuissimum, and this reminds me of it. I tried Zotto's key and this seems to lead to that species (it looks to me that your sample lacks croziers). That species can have yellow VBs and even yellow fruitbodies.

Re : Lachnum on grass
Thank you Juuso for your answer, sorry for my late reaction. I'm learning about this site at this moment, how to use it. 
Without croziers I can follow key 4 from Zotto (-+-), just as you said. I can now add this species to our list.
Thanks again, also on behalf of the other members of our group. We are a small group of Dutch enthusiasts, who search the area off our residence every two weeks. The results will be sent to the NMV (Dutch fungal association).
