Comment: Paul Stamets mentions in his field guide, "Psilocybine Mushrooms of the World" that R. Gordon Wasson first ate 13 pairs of this mushroom during his initial velada with Maria Sabina. However, it was actually seven pairs of mushrooms. Timothy Leary also consumed this mushroom in 1960 in Cuernavaca, Mexico. He was given 7 fresh specimens of Psilocybe caerulescens his friend and associate, anthropologist Frank Baron. This species was first discovered and identified from Huntsville, Alabama in 1924 by the mycologist Murrill and never seen in the United States of America until the early 1990s in Florida and Mississippi. Later in the late 1950s, R. Gordon Wasson and Roger Heim identified it as the Derumbe (Landslide) mushroom of the Mazatec Indians. It has been reported from Oaxaca, Mexico fruiting from sugar cane mulch and landslide areas along sugar cane roads. Many Identification guides list this species as occurring in the southeast states of Mississippi to Georgia and Florida.
