Psilocybe tampanensis is a very rare psychedelic mushroom in the family Hymenogastraceae. Originally collected in the wild in a sandy meadow near Tampa, Florida, in 1977, the fungus would not be found in Florida again until 44 years later. The original Florida specimen was cloned, and descendants remain in wide circulation. The fruit bodies (mushrooms) produced by the fungus are yellowish-brown in color with convex to conic caps up to 2.4 cm (0.9 in) in diameter atop a thin stem up to 6 cm (2.4 in) long. Psilocybe tampanensis forms psychoactive truffle-like sclerotia that are known and sold under the nickname "philosopher's stones". The fruit bodies and sclerotia are consumed by some for recreational or entheogenic purposes. In nature, sclerotia are produced by the fungus as a rare form of protection from wildfires and other natural disasters.
Psilocybe quebecensis is a moderately active hallucinogenic mushroom in the section Aztecorum, having psilocybin and psilocin as main active compounds. Native to Quebec, it is the most northern known psilocybin mushroom after Psilocybe semilanceata in northern Scandinavia. Macroscopically this mushroom somewhat resembles Psilocybe baeocystis.
Psilocybe subaeruginascens is a psychedelic mushroom which has psilocybin and psilocin as main active compounds. This mushroom is closely related to Psilocybe ovoideocystidiata.
Psilocybe galindoi is a psychedelic mushroom in the section Mexicana, having psilocybin and psilocin as its main active compounds. It is also known as Psilocybe galindii. The species was named in honor of Mr. Carlos Galindo Arias and his family by Dr. Gastón Guzmán.
Psilocybe fimetaria is a dung-loving mushroom in the genus Psilocybe. Along with Psilocybe fuscofulva, it is one of two Psilocybe mushroom species that has been found to contain no detectable levels of the psychoactive tryptamines psilocin, psilocybin, or others. In the case of Psilocybe fimetaria, this may be due to some individual specimens having a very low concentration, or the species actually being a pair of morphologically similar species.
Psilocybe graveolens is an extremely rare psilocybin mushroom which has psilocybin and psilocin as main active compounds, discovered in the salt marshes or "meadows" of Hackensack, New Jersey. This mushroom is known for its strong and persistent odor.
Psilocybe liniformans var. americana, is a psilocybin mushroom in the family Hymenogastraceae. It is in the section Semilanceatae of Psilocybe and has psilocybin as its main active compound.
Psilocybe stuntzii, also known as Stuntz's blue legs and blue ringers it is a psilocybin mushroom of the family Hymenogastraceae, having psilocybin and psilocin as main active compounds.
Gymnopilus luteus, known as the yellow gymnopilus, is a widely distributed mushroom-forming fungus of the Eastern United States. It contains the hallucinogens psilocybin and psilocin. It is often mistaken for G. speciosissimus and G. subspectabilis.
Psilocybe plutonia is a small psilocybin mushroom of the family Hymenogastraceae, believed to contain psilocybin and psilocin. It was first documented from Cuba. An older synonym is Agaricus plutonia.
Psilocybe naematoliformis, is a species of fungus in the mushroom family Hymenogastraceae. It is a psilocybin mushroom, having psilocybin and psilocin as the main active hallucinogenic compounds.
Gymnopilus cyanopalmicola is a species of mushroom-forming fungus in the family Hymenogastraceae. Found in tropical Mexico, it was described as new to science by Mexican mycologist Laura Guzmán Dávalos in 2006. The flesh of this mushroom turns blue when bruised, hence the specific epithet.
Psilocybe aztecorum is a species of psilocybin mushroom in the family Hymenogastraceae. Known from central Mexico, Arizona, California, Oregon, Colorado, Canada, India and Costa Rica, the fungus grows on decomposing woody debris and is found in mountainous areas at elevations of 2,000 to 4,000 m, typically in meadows or open, grassy conifer forests. The mushrooms have convex to bell-shaped caps 1.5–2 cm (0.6–0.8 in) in diameter, atop slender cylindrical stems that are up to 7.5 cm (3.0 in) long. The color of the caps changes with variations in hydration, ranging from dark chestnut brown to straw yellow or whitish when dry. The base of the stem is densely covered with conspicuous white rhizomorphs, a characteristic uncommon amongst Psilocybe species.
Psilocybe hispanica is a species of fungus in the family Hymenogastraceae. It produces small brown mushrooms with conical to convex caps up to 10 mm (0.4 in) in diameter and stems 16 to 25 mm long by 0.5 to 1 mm thick. Reported as new to science in 2000, it is only known from the Pyrenees mountain range in northern Spain and southwestern France, where it grows on horse dung in grass fields at elevations of 1,700 to 2,300 m. The mushroom contains the psychoactive compound psilocybin. The possible depiction of this species in the 6,000-year-old Selva Pascuala rock art suggests that it might have been used in ancient religious rituals—the oldest evidence of such usage in prehistoric Europe.
Psilocybe hoogshagenii is a species of psilocybin mushroom in the family Hymenogastraceae. The mushroom has a brownish conical or bell-shaped cap up to 3 cm (1.2 in) wide that has an extended papilla up to 4 mm long. The stem is slender and 5 to 9 cm long. The variety P. hoogshagenii var. convexa lacks the long papilla.
Psilocybe makarorae is a species of psilocybin mushroom in the family Hymenogastraceae. Officially described as new to science in 1995, it is known only from New Zealand, where it grows on rotting wood and twigs of southern beeches. The fruit body (mushroom) has a brownish cap with lighter coloured margins, measuring up to 3.5 cm (1.4 in) wide. The cap shape is either conical, bell-shaped, but as the mushroom grows, it expands to become convex, and it features a prominent umbo. Although the whitish stem does not form a true ring, it retains remnants of the partial veil that covers and protects the gills of young fruit bodies. P. makarorae mushrooms can be distinguished from the similar North American species Psilocybe caerulipes by microscopic characteristics such as the presence of cystidia on the gill faces (pleurocystidia), and cheilocystidia with more elongated necks. Based on the bluing reaction to injury, P. makarorae is presumed to contain the psychedelic compounds psilocybin and psilocin.
Mycena clariviolacea is a mushroom in the family Mycenaceae. First reported as a new species in 2007, it is known only from Kanagawa, Japan, where it fruits on dead fallen twigs in forests dominated by oak and chinquapin trees. Distinctive features of this species are found in its medium-sized, dark violet fruit bodies, with caps up to 25 mm (0.98 in) in diameter and slender stems that are about 30 to 40 mm long. Microscopic characteristics include the amyloid spores, the club-shaped cheilocystidia that are covered with one or more, knob-like, apical protuberances, the absence of pleurocystidia, and the cylindrical, diverticulate caulocystidia.
Pluteus americanus is a North American and Russian psychedelic mushroom that grows on hardwoods.
Psilocybe angulospora is a species of agaric fungus in the family Hymenogastraceae. The species was described from Taiwan in 2015 and is also present in New Zealand, where it is considered introduced. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin.
Psilocybe alutacea is a species of agaric fungus in the family Hymenogastraceae. It was described in 2006 and is known from Australia and New Zealand. It is coprophilous, growing on animal dung. The fruitbodies have a small conical or convex cap, subdistant gills with an adnate attachment, a slender brown stipe and a faint blueing reaction to damage. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin.
