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.

I think that is a myth

I will see if I have a pic of the spores, but I believe it is a myth about the gills not extending below the margin in this species.

They were jet black, I assure you.

Gills seem too far below the margin in a couple of images?

I’m no expert, but in the second to last image, it looks like the gills are extending well below the margin, which seems somewhat uncharacteristic. A spore print image or description would help. Otherwise I’ll say it’s likely to be P. cinctulus.
