A well written and easy to understand book which clearly defines each type of mushroom with illustrations and photographs (in the appendix). It shows how to identify and distinguish between poisonous and hallucinogenic mushrooms (a vital skill). It also gives details on habitat. A useful reference guide. The only extra bit of advice I would give those thinking of ingesting hallucinogenic mushrooms is to always keep a sample in case something goes wrong so they can easily be identified. If in doubt don't pick. This book will certainly help reduces the confusion between similar looking psychotropic and poisonous mushrooms.

In the mid 1970s when Gary Menser wrote Hallucinogenic and Poisonous Mushroom Field Guide, there were virtually no field guides available to the lay public for the psychedelic and poisonous mushrooms of the west coast.
