Psilocybe argentipes is a psilocybin mushroom of the family Hymenogastraceae. It is indigenous to Japan where it is commonly referred to as “Hikageshibiretake”. This fairly potent magic mushroom is said to have a similar potency to P. cyanescens aka Wavy Caps, and reports of accidental ingestions describe vivid yet short lived hallucinogenic effects with a dreamy state of consciousness.
Its epithet refers to the patches of fibrils along the stem that give it a silvery hue.
This moderately to highly psychoactive mushroom is probably growing outside of Japan as well and seems to be well-known for its recreational use. In 2002, it was one of the thirteen magic mushrooms to be prohibited in Japan; amongst them were Copelandia (Panaeolus) cyanescens, Panaeolus subbalteatus,Psilocybe subaeruginascens, Psilocybe cubensis, Psilocybe subcubensis, Psilocybe tampanensis, Psilocybe fasciata, Psilocybe lonchophorus, Psilocybe venenata, Psilocybe subcaerulipes, Panaeolus papilionaceus, and Panaeolus sphinctrinus.
P. argentipe has been used in research to test the effects of its consumption on obsessive-compulsive disorder. Perhaps if these accidental ingestions had not occurred, the idea to use this fairly potent strain to treat O.C.D would’t have seen the day.
