Five cases of poisoning by the indigenous mushroom Hikageshibiretake (Psilocybe argentipes) are described. Since this mushroom contains psilocybin, clinical features generally resembled those of pure psilocybin. One case involved an acute toxic stuporous state with complete amnesia during the culminating period, one case involved a psychedelic state with dreamy consciousness, and three cases involved psychotic adverse reactions with vivid visual hallucinations while conscious. These experiences were accompanied by anxiety and panic reactions. Although the toxic effects were usually short-lived, the report emphasizes that horrible emotional reactions and harmful behavioral problems can occur, which is important for patient management.
