Psilocybe cubensis

Golden cap

A large tropical and subtropical mushroom with golden-brown caps that grows on cattle dung and rich pasture soil across the warm Americas, Asia and Australia. It is the psilocybin mushroom most often grown indoors, fruiting readily at warm room temperature on grain and dung-based or coir substrates. Psilocybin is a controlled substance in most countries, and growing this mushroom is illegal in many places; check local law before cultivating.

Where it grows wild

A saprotroph on cow and water buffalo dung, dung-enriched pasture soil and sugar cane mulch in warm, humid grazing land. It fruits in the warm wet season, and cattle egrets and livestock spread it.
