Psilocybe mexicana is a psychedelic mushroom. Its first known usage was by the natives of North and Central America over 2,000 years ago. Known to the Aztecs as teotlnanácatl, from the Nahuatl teotl ("god") + nanácatl ("fungus"). This species was categorized by French botanist Roger Heim.
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.
Panaeolus cyanescens is a mushroom in the Bolbitiaceae family. Panaeolus cyanescens is a common psychoactive mushroom and is similar to Panaeolus tropicalis.
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 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 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 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 samuiensis is a psychedelic mushroom, which has psilocybin and psilocin as main active compounds. It was placed in the section Mexicanae of genus Psilocybe by Gastón Guzmán due to its rhomboid-shaped spores. It has been found in Koh Samui, a small tropical island in Thailand, where some psychoactive species are consumed by both natives and tourists. Chao Samui rarely consume psilocybian fungi. Such local use is usually restricted to local females who do so at the request of foreigners.
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 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 neoxalapensis is a species of psilocybin mushroom in the family Hymenogastraceae. Found in Veracruz, Mexico, it was originally described in 2005 under the name Psilocybe novoxalapensis, but this naming was later determined to be invalid, and it was renamed P. neoxalapensis in 2009. It is in the Psilocybe fagicola complex with Psilocybe fagicola, Psilocybe oaxacana, Psilocybe banderillensis, Psilocybe columbiana, Psilocybe keralensis, Psilocybe herrerae, and Psilocybe teofiloi.
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.
