Known members of this group include Amanita muscaria , Inocybe patouillardi , Inocybe fastigiata and Clitocybe dealbata . These are hallucinogenic substances which act on the central nervous system. When a large amount of Amanita muscaria containing these toxins is ingested it often results in severe illness but victims usually recover. Known members of this group include Amanita muscaria , Amanita pantherina , Amanita solitaria, Amanita porphyria, Amanita citrina, Panaeolus campanulatus and Panaeolus sp. These well-known LSD compounds have a strong hallucinogenic effect on the central nervous system, producing visions, smothering sensations and optical distortions.
Some victims report religious or mystical experiences.
Eating large amounts of mushrooms in this group could cause severe toxic effects and be fatal. Known members of this group include Psilocybe cubensis, Psilocybe timentaria, Psilocybe mexicana, Psilocybe semilanceata, Psilocybe caerulescens, Conocybe cyanescens, Conocybe cyanopus and Panaeolus foenisecii. Boiling them removes a certain amount of the toxin and some may be safe to eat. However, note that MMH causes blood poisoning and affects the central nervous system, producing diarrhea, vomiting and loss of muscle coordination, with severe headaches and pains lingering for some time. A number of victims have died from eating false morels and as the number of species and how to tell them apart is uncertain, it is safest not to eat any.
