PSILOCYBE ARGENTIPES

Psilocybe argentipes K. Yokoyama

Psilocybe argentipes is a psilocybin-producing mushroom 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 “argentines” refers to the patches of fibrils along the stem that give it a silvery hue.
Undeniably, P. argentipes’ most special feature is that it is amongst the rare psilocybin candidates to have been used in research on obsessive compulsive disorder OCD.

It is always interesting to see mushrooms make their way from “accidental ingestions” to “clinical research”. We can all agree, fungi have a “way” to educate and if P. argentines can help treat O.C.D, it’s a relief to know someone is on the case to figure out why.

Though it is native to Japan, Psilocybe argentipes is probably more widely spread as actual data suggests. In Japan where magic mushroom foraging and recreational use are common, Psilocybe argentipes was one of the thirteen magic mushrooms to be prohibited in 2002; 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. If you ever go to Japan, that gives you a good idea of what you will find in the woods.

PSILOCYBE ARGENTIPES Effects

Said to be fairly potent with a potency similar to P. cyanescens. Accidental ingestion of P. argentipes is reported as a “poisoning by indigenous mushroom Hikageshibiretake”, and described various effects on those who consumed it such as “psychedelic state with dreamy consciousness, psychotic adverse reactions with vivid visual hallucinations, accompanied with anxiety and panic reactions to subjective experiences”. It is said effects were usually short-lived but seemed to leave emotional trauma. Nota bene: literature is subjective, for example, emotional trauma, could be transformative for those who consume it with an intention.
