Cheilymenia on moose dung
Juuso Äikäs, 08-05-2023 11:11
I found a few Cheilymenia fruitbodies yesterday, growing on a pile of moose dung. The largest fruitbody is over 3 mm wide.

The hairs are max. 650 µm long and many are forked at the base. No stellate hairs. The spores are completely smooth in water and cotton blue. Measurements:

(19.2) 19.8 - 21.3 (21.6) × (10) 10.4 - 11.3 (11.5) µm
Q = (1.7) 1.8 - 2 ; N = 20
Me = 20.4 × 10.8 µm ; Qe = 1.9

Although it apparently usually grows on cow dung, could this be C. fimicola?

Re : Cheilymenia on moose dung
I tried to make a section, but without much success. If C. fimicola is indeed a nomen dubium, maybe this might be named C. coprinaria? I believe the spores are however rather large for it.

Re : Cheilymenia on moose dung
I managed to make a better section, and the extal excipulum is made of large (up to 80 µm) globose - angular cells, and the medulla seems like an unclear textura intricata. There doesn't seem to be a well-defined subhymenium. Hymenium 285 µm thick. Also, the spores appear to have a loosening perispore in heated CB.

Aside from the large spores and thick hymenium, this would seem to still fit C. coprinaria.

Good evening.

Indeed the spores are a little different in size, but despite everything I think you are in the right direction with C.coprinaria. Difficult to disentangle sometimes according to the authors the various authors.

Re : Cheilymenia on moose dung
Good evening Michel, and thank you for the assesment! I think this is what I will label this.
