The gross appearance is Coprinopsis marcescibilis.

has a fibrillose pileus that becomes glabrous with time, even on the young specimens I don’t see this feature. A similar species is Coprinopsis marcescibilis (Descriptions can be found under the name Psathyrella fragilissima in the Smith book) which doesn’t have a fibrillose pileus at any stage. I think Arora may mention this species in MD under the name P. elwhaensis under the P. longipes description which is a similarly described species that I think some sources consider a C.marcescibilis synonym, but I don’t have details on that.

Microscopy could go a long way I think (Spores and cystidia mostly).
For comparison, see obs 87767 & 88247.
