Panaeolus bisporus, also known as Copelandia bisporus is a rare and widely distributed little brown mushroom that bruises blue and contains the hallucinogen psilocybin.
This mushroom is similar macroscopically to Panaeolus tropicalis , Panaeolus cambodginiensis and Panaeolus cyanescens , but can be differentiated using a microscope by its two spored basidia.
This is a little brown mushroom that grows on dung and has black spores. It has been found in Hawaii, Southern California, North Africa, Spain and Switzerland.
Cap: 15-30 mm tan to gray fading to black sometimes when covered with spores and with a defined ring zone somewhat globe shaped or bell shaped to convex, hardly expanding, margin often torn and pedaled, smooth not viscid, and slightly wrinkled and pitted with age. Dark grey-brown drying whitish.
Gills: adnexed or narrowly attachedtightly packed, mottled gray to jet black, white edges
Stem: white, fibrous, 65-120 mm long 2-3 mm thick, hollow, translucent gray, bruising heavily blue where bruised
Spores: jet black, elliptical, 12-14 x 8-10 x 6-7.5 µm smooth and opaque, elongated with germ pore straight off the end
Habitat: saprotrophic on grasses
Microscopic features: 2 spored basidia 18 - 23 × 8-10 µm, cheilocystidia are bottle shaped and clear 20-30 µm, metuloids with yellow brown walls 40-55 × 12-15 µm some with excreted crystals
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. Toadstool generally denotes one poisonous to humans.
Agaricus bisporus is an edible basidiomycete mushroom native to grasslands in Eurasia and North America. It has two color states while immature – white and brown – both of which have various names, with additional names for the mature state.
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 in mass, ellipsoid in shape, and measure 10.5–15 by 6.5–8.5 micrometres.
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.
Panaeolus cinctulus, syn. Panaeolus subbalteatus, commonly known as the banded mottlegill, weed Panaeolus or subbs is a very common, widely distributed psilocybin mushroom. According to American naturalist and mycologist David Arora, Panaeolus cinctulus is the most common psilocybin mushroom in California.
Panaeolus is a genus of small, black-spored, saprotrophic agarics. The word Panaeolus is Greek for "all variegated", alluding to the spotted gills of the mushrooms produced.
Panaeolus tropicalis is a species of psilocybin producing mushroom in the family Bolbitiaceae. It is also known as Copelandia tropicalis.
Panaeolina is a small genus of small mushrooms, containing only about four species. They are a subgroup of Panaeolus which have dark brown spores. The type species is Panaeolina foenisecii, a common lawn mushroom. Members of Panaeolina are broadly distributed throughout the world.
Panaeolus cyanescens is a mushroom in the Bolbitiaceae family. Panaeolus cyanescens is a common psychoactive mushroom and is similar to Panaeolus tropicalis.
Panaeolus africanus is a little brown mushroom that contains irregular amounts of the hallucinogens psilocybin and psilocin. It has been found in central Africa and southern Sudan.
Panaeolus antillarum is a species of mushroom in the family Bolbitiaceae. It is edible but not commonly eaten. It is found from northern North America through Mexico into northern South America.
Panaeolus cambodginiensis is a potent hallucinogenic mushroom that contains psilocybin and psilocin. It was described in 1979 as Copelandia cambodginiensis.
Panaeolus olivaceus is a widely distributed, seldom identified, little brown mushroom that contains the hallucinogen psilocybin; it is often mistaken for Panaeolina foenisecii and is distinguished by its black spore print and darker gill coloration when mature alongside a slightly thicker stem. It is even more easily mistaken for Panaeolus cinctulus or Panaeolus fimicola and can be distinguished from them both by its slightly roughened spores. It is also easily confused with Panaeolina castaneifolia, a species which has spores that are dark brown and significantly more roughened.
Panaeolus fimicola is a widespread but seldom identified "little brown mushroom" which sometimes contains small amounts of the hallucinogen psilocybin. Panaeolis ater is a synonym. The species is also referred to as the "turf mottlegill".
Panaeolus foenisecii, commonly called the mower's mushroom, haymaker or brown hay mushroom, is a very common and widely distributed little brown mushroom often found on lawns and is not an edible mushroom. In 1963 Tyler and Smith found that this mushroom contains serotonin, 5-HTP and 5-hydroxyindoleacetic acid. In many field guides it is listed as psychoactive; however, the mushroom does not produce any hallucinogenic effects.
Panaeolus papilionaceus var. parvisporus is a little brown mushroom that grows in horse or cow dung and is in the genus Panaeolus.
Panaeolus papilionaceus, also known as Agaricus calosus, Panaeolus campanulatus, Panaeolus retirugis, and Panaeolus sphinctrinus, and commonly known as Petticoat mottlegill, is a very common and widely distributed little brown mushroom that feeds on dung.
Panaeolus semiovatus var. semiovatus, also known as Panaeolus semiovatus and Anellaria separata, is a medium-sized buff-colored mushroom/toadstool that grows on horse dung, and has black spores. Though nonpoisonous, it is generally regarded as inedible, and a few people experience gastric upset after consumption. Its common names are the shiny mottlegill, or egghead mottlegill.
Panaeolina castaneifolia is a rare and widely distributed little brown mushroom.
Panaeolus microsporus is a species of mushroom in the Bolbitiaceae family. It is a psychoactive species of the Panaeolus genus, containing alkaloids like psilocybin and psilosin. All Panaeolus species produce serotonin and serotonin derivatives.
