Wavy Caps Psilocybe cyanescens Wavy Caps (also known as wavy caps or the potent Psilocybe) is a powerful hallucinogenic mushroom species. Psilocybin and psilocin are the primary chemicals responsible for its psychedelic effects. It is a member of the Hymenogastraceae family.
P. cyanescens is the name of the species.
Psilocybe is a genus of fungi.
Hymenogastraceae is a family of plants.
Because all of the psychoactive components in P. cyanescens are water-soluble, parboiling the fruiting bodies renders them non-psychoactive, allowing them to be used in cooking. However, because most people find them bitter and they are too little to be of any nutritional value, this is not a common practice.
The hygrophanous pileus (cap) of Psilocybe cyanescens is caramel to chestnut-brown while wet, fading to pale buff or slightly yellowish when dry. Caps range in size from 1.5 to 5 cm (12″ to 2″) across and are usually wavy when fully mature.  Outside of the P. cyanescens species complex, the pileus color is rarely seen in mushrooms.
Small brown mushrooms can be difficult to spot, and some of them are extremely dangerous. Psilocybe species can be distinguished from small, brown mushrooms that contain fatal toxins by their spore prints. The mushroom could be a Psilocybe if the spores are dark purplish brown. If the spore print is rusty brown or cinnamon brown, the mushroom isn’t a Psilocybe and could be a Galerina or Conocybe species, both of which contain severe liver-damaging amatoxins. Like Ps. cyanescens, the deadly toxic Galerina marginata can grow on wood chips. Galerina marginata’s stem becomes black(ish) with age, but never blue. In comparison to Ps. cyanescens, it also has a considerably more pronounced fibrous ring on the stem. When G. marginata spreads, its crown does not normally become wavy. Keep an eye out for the color difference between Ps. cyanescens and Galerina marginata: blue stems in Ps. cyanescens and black stems in Galerina marginata. Don’t fool yourself into thinking black is blue!
The hygrophanous pileus (cap) of Psilocybe cyanescens is caramel to chestnut-brown while wet, fading to pale buff or slightly yellowish when dry. Caps range in size from 1.5 to 5 cm (12″ to 2″) across and are usually wavy when fully mature. Outside of the P. cyanescens species complex, the pileus color is rarely seen in mushrooms. When handled or otherwise disturbed, most portions of the mushroom, including the cap and Lamellae (gills beneath the crown), tint blue, most likely owing to psilocin oxidation. The lamellae are adnate and mature to a light brown to dark purple brown with paler gill margins. Although there is no identifiable annulus, juvenile P. cyanescens specimens have a cobwebby veil that may grow into an annular zone. The odor and flavor are both farinaceous.
The spores of P. cyanescens are elliptical in shape, measuring 9–12 x 5–8 m.  Some publications claim that the species’ holotype collection from Kew Gardens has no pleurocystidia, however North American samples have common clavate-mucronate pleurocystidia.   Pleurocystidia, on the other hand, are found in the holotype collection (but not easily to observe since hymenium is collapsed). Pleurocystidia are frequent in European P. cyanescens collections, and their form is identical to those found in the United States. An epitype from Hamburg, Germany, was named in 2012.
When P. cyanescens sporocarps and mycelia are damaged, they bruise blueish or blue-green, and the staining is noticeable after drying. This staining is most noticeable on the stem (which is white when undisturbed), but it can also appear on the gills, cap, and mycelium. The oxidation of psilocin is the primary cause of this discoloration. (Psilocybin cannot be directly oxidized.)
P. cyanescens and its cousins are commonly cultivated and collected for recreational purposes by a worldwide population of neuronauts and other thrill seekers. Ingestion can produce wonderful and/or overwhelming visual enhancements/disturbances, heightened sensations, cyclical and often “swelling” feelings of ecstasy, euphoria, and connection to place, people, Nature, Time, and the Universe, but it can also produce feelings of fear, unease, disconnection, and loss of sense of self. Personal predispositions and psychic idiosyncrasies, in combination with set and setting specifics, have a significant impact on the tone of the trip, as they do with any psychedelic medication.
Psilocybin-containing mushrooms are classed as Schedule 1 substances in the United States, making them unlawful to possess, sell, transport, or cultivate (this includes spores in the State of California).
