Cheilymenia on moose dung

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.

Re : Cheilymenia on moose dung
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.
