and not observed. strange, considering how seemingly mature so much of the material was. therefore neither spore print nor spore characters were obtained. i lacked the clout to designate specimens for transfer to the US. Ana Esperanza was a bit… chilly on the subject.

I just think

Sticking this under Agaricales sensu lato without any substantial reasons other than “It feels different” is kind of weak. Do you have any other suggestions? What other genera can be mistaken for Crepidotus? I should take it spore info was not recorded?

why so confident?

i have never held a Crepidotus as tough and pliable as this, and just about every description of cheilocystidia I have read for the species of Crepidotus said to possess them describes significantly longer, slenderer, narrower, more flask-shaped formations than what I observed. i would consider chalking this up to looking at immature material if I hadn’t mounted more than one obviously mature gill sections and found cystidia of a more or less uniform size and shape throughout: tiny ping pong paddles.

but the texture seemed far too sturdy. they were almost leathery. there is also the question of the abundant cheilocystidia mentioned in the notes, which was, unfortunately, the only significant microfeature observed.
