Psilocybe mushrooms

Psilocybe cubensis

Hymenogastraceae

A well-known psychoactive woodland and pasture genus, now in clinical trials for depression — still illegal to grow or possess in most places.

Psilocybin and psilocin are US Schedule I substances. The mushrooms that contain them are illegal to cultivate, possess, or distribute under federal law, with narrow local decriminalization in a few cities and licensed research/therapy programs. Tennessee has not decriminalized them.

Parts used: Fruiting body — in licensed research only
Traditional notes: Mesoamerican ceremonial use (other Psilocybe species) · Supervised clinical research (modern)
Habitat only: P. cubensis is associated with well-manured subtropical pasture. Other Psilocybe species inhabit wood chips and mossy conifer woods. Habitat notes are for scientific literacy, not for collecting.

No cultivation, extraction, or dosing notes. Possession is illegal in most of the US.
The map is tropical grassland habitat, not a place to hunt.
Lookalikes include deadly galerinas. This is a law-and-harm plate.

Lookalikes

Button mushroom — Little brown mushrooms are a legal and medical problem, not a pizza topping. This catalog will name them for education. It will not tell you to eat them.

Lore

Mazatec and other Mesoamerican traditions used Psilocybe in ceremony long before a New York banker coined ‘magic mushroom’ in 1957. The species is a legal object in most of the US. The plate names it so the law and the lookalike can be seen together.

The Herbarium — a teaching catalog, not a clinic. Traditional use is history, not a prescription. USDA 6b dates are a week either way, not a promise. Do not eat, drink, or harvest a plant you cannot name.
