Psilocybe semilanceata, commonly known as the liberty cap, is a species of fungus which produces the psychoactive compounds psilocybin, psilocin and baeocystin. It is both one of the most widely distributed psilocybin mushrooms in nature, and one of the most potent. The mushrooms have a distinctive conical to bell-shaped cap, up to 2.5 cm (1 in) in diameter, with a small nipple-like protrusion on the top. They are yellow to brown, covered with radial grooves when moist, and fade to a lighter color as they mature. Their stipes tend to be slender and long, and the same color or slightly lighter than the cap. The gill attachment to the stipe is adnexed, and they are initially cream-colored before tinting purple to black as the spores mature. The spores are dark purplish-brown en masse, ellipsoid in shape, and measure 10.5–15 by 6.5–8.5 micrometres.
Psilocybe cyanescens, commonly known as the wavy cap or potent psilocybe, is a species of potent psychedelic mushroom. The main compounds responsible for its psychedelic effects are psilocybin and psilocin. It belongs to the family Hymenogastraceae. A formal description of the species was published by Elsie Wakefield in 1946 in the Transactions of the British Mycological Society, based on a specimen she had recently collected at Kew Gardens. She had begun collecting the species as early as 1910. The mushroom is not generally regarded as being physically dangerous to adults. Since all the psychoactive compounds in P. cyanescens are water-soluble, the fruiting bodies can be rendered non-psychoactive through parboiling, allowing their culinary use. However, since most people find them overly bitter and they are too small to have great nutritive value, this is not frequently done.
Panaeolus cyanescens is a mushroom in the Bolbitiaceae family. Panaeolus cyanescens is a common psychoactive mushroom and is similar to Panaeolus tropicalis. It is also known under the common names of Blauender Düngerling, blue meanies, faleaitu (Samoan), falter-düngerling, Hawaiian copelandia, jambur, jamur, pulouaitu (Samoan), taepovi (Samoan), tenkech (Chol).
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).
Gymnopilus braendlei is a species of agaric fungus in the family Hymenogastraceae that contains the hallucinogens psilocybin and psilocin. It was originally described by mycologist Charles Horton Peck as Flammula braendlei, from specimens found in the District of Columbia in 1902.
Psilocybe rostrata is a species of mushroom in the family Hymenogastraceae.
Psilocybe dumontii is a species of mushroom in the family Hymenogastraceae.
Psilocybe egonii is a species of mushroom in the family Hymenogastraceae.
Psilocybe furtadoana is a species of mushroom in the family Hymenogastraceae.
Psilocybe indica is a species of mushroom in the family Hymenogastraceae. The mushroom contains psilocybin, a prodrug for the psychedelic tryptamine psilocin.
Psilocybe isabelae is a species of mushroom in the family Hymenogastraceae. The mushroom contains the psychoactive compound psilocybin.
Psilocybe laurae is a species of mushroom in the family Hymenogastraceae. The mushroom contains the psychoactive compound psilocybin.
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.
Psilocybe mammillata is an extremely rare species of mushroom in the family Hymenogastraceae. The mushroom contains the psychoactive compound psilocybin.
