Who: AmatoxinApocalypse (AmatoxinApocalypse)

No specimen available

Found in an area that was seeded at the beginning of the year, I was surprised to see such robust specimens in such a new area, I usually observe these in horse dung or well fertilized/well established lawns.

The average length of the stipe was 5 inches long, some were 7 inches long. Most were very large.


Note spore deposits on surrounding grass.

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.
