A full-color guide to psilocybin mushrooms--how to forage, identify, grow, and use them--with detailed descriptions, 300 stunning photographs, tips for dosing safely, and more, from a world-renowned mycologist. The past decade has seen an explosion of interest in using psilocybin (aka psychoactive or "magic") mushrooms for recreational and medicinal purposes. In this comprehensive, full-color reference, Paul Stamets offers descriptions and 300 photographs of more than 60 psilocybin varieties and their lookalikes common to North America, Europe, and Australasia. He outlines the history and cultural use of magic mushrooms in traditional rituals and ceremonies, their natural geographic distribution and habitats, and keys to growing your own mushroom patch. But perhaps most important, Stamets explains how to reliably distinguish between a non-poisonous, psychoactive mushroom and one of its highly toxic, even deadly, lookalikes. Packed with a lifetime of scientific and real-world research, Psilocybin Mushrooms in Their Natural Habitats brings depth and understanding to an often-misunderstood topic. Revealing the potential of these powerful, mind-awakening fungi to help us live better, happier lives through micro- and macro-dosing, this handbook is an indispensable--and potentially lifesaving--addition to mushroom field guides from the biggest name in mycology.
