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.
