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 azurescens is a species of psychedelic mushroom whose main active compounds are psilocybin and psilocin. It is among the most potent of the tryptamine-bearing mushrooms, containing up to 1.8% psilocybin, 0.5% psilocin, and 0.4% baeocystin by dry weight, averaging to about 1.1% psilocybin and 0.15% psilocin. It belongs to the family Hymenogastraceae in the order Agaricales.
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 baeocystis is a psilocybin mushroom of the family Hymenogastraceae. It contains the hallucinogenic compounds psilocybin, psilocin and baeocystin. The species is commonly known by various names such as bottle caps, knobby tops, blue bells, olive caps.
Psilocybe ovoideocystidiata is a psilocybin mushroom, having psilocybin and/or psilocin as main active compounds. It is closely related to P. subaeruginascens from Java, P. septentrionalis from Japan, and P. wayanadensis from India. This mushroom was first documented by Richard V. Gaines in Montgomery County, Pennsylvania in June 2003. Although it is sometimes confused with Psilocybe caerulipes, it can be distinguished by its rhomboid spores, larger stature, earlier fruiting season and membranous annulus.
Psilocybe caerulipes, commonly known as blue-foot, is a rare psilocybin mushroom of the family Hymenogastraceae, having psilocybin and psilocin as main active compounds. An older synonym is Agaricus caerulipes.
Psilocybe atlantis is a rare psychedelic mushroom that contains psilocybin and psilocin as main active compounds. It is a close relative of Psilocybe mexicana and has been recorded only from Georgia. It has a pleasant taste and smell.
Psilocybe zapotecorum is a psilocybin mushroom which has psilocybin and psilocin as main active compounds. It is in the section Zapotecorum.
Psilocybe subaeruginosa is a species of agaric fungus in the family Hymenogastraceae described in 1927 and known from Australia and New Zealand. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin.
Psilocybe strictipes is a mushroom that grows on grassy meadows and lawns; It is found throughout the cool temperate and subarctic regions of the Northern Hemisphere and it is most common in Europe, and the Pacific Northwest region of North America. It contains the psychoactive compound psilocybin is closely related to Psilocybe semilanceata and Psilocybe pelliculosa. Psilocybe strictipes is commonly confused with Psilocybe semilanceata and can be differentiated by its lack of a papilla and a convex to subumbonate cap. "Strictipes" comes from the Latin words stricti (narrow) and pes (foot).
Psilocybe guilartensis is a psilocybin mushroom which has psilocybin and psilocin as main active compounds. It is common in Puerto Rico.
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 caerulescens, also known as landslide mushroom, is a psilocybin mushroom having psilocybin and psilocin as main active compounds. Along with Psilocybe mexicana and Psilocybe aztecorum, it is one of the mushrooms likely to have been used by the Aztecs and is currently used by Mazatec shamans for its entheogenic properties.
Psilocybe mescaleroensis is a psychedelic mushroom which has psilocybin and psilocin as main active compounds. This mushroom is closely related to Psilocybe hopii and Psilocybe cyanescens. It was brought to scientific attention by Lee Walstad.
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.
Psilocybe cyanofibrillosa, also known as rhododendron psilocybe and blue-haired psilocybe, is a psilocybin mushroom of the family Hymenogastraceae having psilocybin and psilocin as main active compounds. First documented in 1980 in the Pacific Northwest, it is relatively uncommon and can be distinguished from other closely related species by its smaller spores and forking cheilocystidia. Psilocybe cyanescens also has forking cheilocystidia, but less often than Psilocybe cyanofibrillosa. Psilocybe cyanofibrillosa is also distinguished from Psilocybe cyanescens by an absence of pleurocystidia. The name of this species refers to the fibrils on the Stipe (mycology) that turn bluish in age, or when handled.
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.
Psilocybe aztecorum is a species of psilocybin mushroom in the family Hymenogastraceae. Known from Arizona, Colorado, central Mexico, 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 allenii is a species of agaric fungus in the family Hymenogastraceae. Described as new to science in 2012, it is named after John W. Allen, who provided the type collection. It is found in the northwestern North America from British Columbia, Canada to Los Angeles, California, most commonly within 10 miles (16 km) of the Pacific coast.
