Proposed Names

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.

Recognized by sight: Micro is needed to determine species, P. subbalteatus has a garbage description which is impossible to tell is even Panaeolus and a really old type collection no one has even looked at while P. cinctulus has a very clear epitype and somewhat clear old drawing.

Could point to another species, P. cinctulus has a darker, redder stem. In its faded state, its pretty impossible to tell without micro, this might even be more true for FL?

thanks Alan…
