Observation 83511: Panaeolus subbalteatus (Berk. & Broome) Sacc.
When: 2010-06-16
Who: Panz
No herbarium specimen

Notes: Surprisingly the cluster was on the side of a dirt road with mixed in field grass tufts. I noticed the snapshot from a sideglance while driving. It appeared that maybe there had been some tilling from roadwork in recent year or more to cause burred plant/grass stalks in the soil. The trees surrounding area were ponderosa, bull pine, fir and tamarack. Cinctulus are actually quite prevalent in the Colville river valley/drainage. Easy to find after heavy spring/summer/fall rains in Manure/hay compost piles where good conditions exist. But fruiting like this is nearly impossible. Felt privileged to be a witness and to still have the spores.

Recognized by sight: I could see belted zone and outline from car while driving… Stopped and to my amazement there was the biggest, meatiest Cintulus I have ever seen growing on the side of a rural road outside of Chewelah Washington. later the spore print matched the Jet black.

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.
