MUSHA, M., ISHII, A., TANAKA, F. and KUSANO, G. Poisoning by Hallucinogenic Mushroom Hikageshibiretake (Psilocybe argentipes K. Yokoyama) Indigenous to Japan. Tohoku J. exp. Med., 1986, 148 (1), 73-78-Five cases of poisoning by indigenous mushroom Hikageshibiretake (Psilocybe argentipes) are reported. As this mushroom contains psilocybin, in general, clinical features were similar to those seen by pure psilocybin. Acute toxic stuporous state with complete amnesia in the culminating period occurred in one case, psychedelic state with dreamy consciousness in one case and psychotic adverse reactions with vivid visual hallucinations with consciousness in three cases. There were accompanied with anxiety and panic reactions to subjective experiences. Though these toxic effects were usually short-lived, for management of such patients it is important to recognize that horrible emotional reactions and other harmful behavioral problems can also occur.
