It has been found in Vietnam, Africa (including South Africa, Madagascar and Democratic Republic of the Congo), Australia, Belize, the Caribbean (Bermuda, Grenada, Barbados Jamaica, Trinidad, and Puerto Rico) Costa Rica, India, Malaysia, Indonesia, Sri Lanka, Cambodia, Thailand, Japan, Mexico, Oceania (Fiji and Samoa), the Philippines, South America (Bolivia, Brazil, Paraguay, Colombia, Venezuela, and Ecuador), South Korea, and the United States (California, Hawaii, Louisiana, Mississippi, Alabama, Florida, Tennessee, Texas, Kentucky, Virginia, and North Carolina).

Alkaloid content

Laussmann & Sigrid Meier-Giebing (2010) reported the presence of psilocybin at 2.5% and psilocin at 1.194% average from 25 samples seized by German customs that were shipments from commercial growers (making modern commercially cultivated strains of this species the most potent hallucinogenic mushrooms ever described in reputable published research). Other researchers have documented a significant presence of serotonin and urea in this species as well as the presence of baeocystin which may also be psychoactive.
