Panaeolus cinctulus, syn. P. subbalteatus, commonly known as the belted panaeolus,[1] banded mottlegill, or Template:Not a typo, is a very common, widely distributed psilocybin mushroom.

Etymology

The descriptor subbalteatus comes from the Latin words sub ('somewhat') and balteat ('girdled'), a reference to the dark outer band of the cap.[2]

Description

The cap is Script error: No such module "convert". wide,[1] hemispherical to convex when young to broadly umbonate or plane in age,[2] smooth, hygrophanous, striking cinnamon-brown when moist, soot-black when wet which disappears as the mushroom completely dries out. The outer band is usually darker.[2] The flesh is thin and brownish.[1]

The gills are close, adnate to adnexed, cream-colored when young, later mottled dingy brown then to soot-black.[1] The gill edges are white and slightly fringed, but turn blackish when fully mature.[3] The spore print is black.[4]

The stipe is 4–10 cm long, 1–10 mm thick, equal or tapered at the ends, reddish brown or covered by whitish powder, hollow,[1] no veil remnants, longitudinally white-fibrillose, striate at the apex or twisting vertically down the entire length of the stipe. The stem base and mycelium occasionally stain blue.[1]

The taste is farinaceous (like flour) when fresh, saliferous (salty) when dried. The odor is slightly farinaceous.

Microscopic features

The spores are 11–16 x 7.5–10 x 6–9 μm, smooth, elliptical to rhomboid in face view, thick-walled, elliptical in side view.

Similar species

Morphologically, P. cinctulus can be easily confused with other species of psilocybin mushrooms.[1] They have a resemblance to P. fimicola and prefer the same habitats, but the latter species has sulphidia on the gill faces.

It can also resemble P. foenisecii and P. olivaceus.[4]

Habitat and formation

Panaeolus cinctulus is a cosmopolitan species that grows solitary to gregarious to cespitose (densely clumped) on compost piles, well-fertilized lawns and gardens, and, rarely, directly on horse dung.[5] It grows from spring to fall, abundantly after rain. It can be found in many regions, including: Africa[6] (South Africa),[6] Austria,[6][7] Canada (Alberta, British Columbia, New Brunswick, Prince Edward Island, Ontario, Quebec, Nova Scotia),[6] Denmark,[7] Finland,[8] France,[6] Germany,[6][7] Great Britain,[6] Guadeloupe,[7] Estonia,[6] Iceland,[6] India,[6] Ireland,[6] Italy,[6] South Korea,[6] Japan,[6] Mexico,[8] New Guinea,[6] New Zealand,[6] Norway,[7] Philippines,[6] Russia,[6] Slovenia,[7] South America (Argentina, Chile, Brazil)[6] and the United States (common in Oregon, Alaska, Washington, and both northern and southern California, but known to occur in all 50 states).Script error: No such module "Unsubst".

According to American mycologist David Arora, P. cinctulus is the most common psilocybin mushroom in California. [1]

It has also been sighted in Melbourne, Australia, Central Queensland, Australia Belgium and the Czech Republic.Script error: No such module "Unsubst".

Legality

Script error: No such module "Labelled list hatnote". The legal status of psilocybin mushrooms varies worldwide. Psilocybin and psilocin are listed as Class A (United Kingdom) or Schedule I (US) drugs under the United Nations 1971 Convention on Psychotropic Substances.[9] The possession and use of psilocybin mushrooms, including P. cinctulus, is therefore prohibited by extension. However, in many national, state, and provincial drug laws, there is a great deal of ambiguity about the legal status of psilocybin mushrooms and the spores of these mushrooms. Panaeolus cinctulus is mildly psychoactive.[2]

In culture

During the early 1900s, these species were referred to as the "weed Panaeolus" because they were commonly found in beds of the commercially grown, grocery-store mushroom Agaricus bisporus. Mushroom farmers had to weed it out from the edible mushrooms because of the psilocybin content.[10]
