Recognized by sight: Brown mature gills, stem without reddish staining, brown cap, the print in the pic looks in one of the ambiguous stages between black and brown…looking to see if the spores are ornamented or smooth would really help. At least there are more species to consider then P. cinctulus.

Recognized by sight: The species concept of Agaricus (Panaeolus) cinctulus is based on a drawing made by Bolton in 1791. No type collection exists. Since it is not possible to know whether Bolton’s species was Panaeolus subbalteatus, P. olivaceus or P. fimicola, I consider Panaeolus cinctulus to be a nomen dubium.
Based on microscopic features: The gill faces need to be checked for sulphidia; the presence of these would indicate that it is probably Panaeolus fimicola.

Thought this was far too large to be panaeolina- but could be wrong… I’ll keep it there for the time being.
Spore print seems to be distinctly black tho…
