The Poisonous and Hallucinogenic Mushrooms program was prepared by Michael Beug for the education committee of the North American Mycological Association. This program is intended for all people interested in mushrooms and for physicians dealing with a suspected mushroom poisoning. Many, but not all, North American poisonous mushrooms and their symptoms are described in the following program. 

Physicians treating a suspected mushroom poisoning case are advised to consult with their regional poison control center for treatment advice and to contact experienced mushroom identifiers to confirm mushroom identifications, especially when dealing with mushrooms where the onset of symptoms exceeds 3 hours.
