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.

Panaeolus subbalteatus

This one looks more like Panaeolus subbalteatus than Panaeolus foenisecii because the gills are black rather than walnut brown. P. subbalteatus also has closer, flatter gills, a thicker stem, and smoother spores. Observation 4468 is P. foenisecii.
