The species is found in Mexico, where it grows singly or in small groups in clayey soils in subtropical coffee plantations, and from Colombia and Brazil in South America. The mushroom contains the psychedelic compounds psilocybin and psilocin, and all parts will stain blue or bluish black when handled or injured.
