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.
Panaeolus cinctulus, syn. Panaeolus subbalteatus, commonly known as the banded mottlegill, weed Panaeolus, belted 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 cyanescensis a mushroom in the Bolbitiaceae family. Panaeolus cyanescens is a common psychoactive mushroom and is similar to Panaeolus tropicalis.
Panaeolus acuminatus, also known as Panaeolus rickenii, is a species of mushroom in the family Bolbitiaceae.
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 bisporus, also known as Copelandia bisporus is a rare and widely distributed little brown mushroom that bruises blue and contains the hallucinogen psilocybin.
Panaeolus olivaceus is a widely distributed, seldom identified, little brown mushroom that contains the hallucinogen psilocybin; it is often mistaken for Panaeolus 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. Panaeolus ater is a synonym. The species is also referred to as the "turf mottlegill".
Panaeolus foenisecii, commonly called the mower's mushroom, haymaker, haymaker's panaeolus, 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 semiovatus var. semiovatus, also known as Panaeolus semiovatus and Anellaria separata, and commonly known as the shiny mottlegill, ringed panaeolus, or egghead mottlegill, is a medium-sized buff-colored mushroom 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.
Gymnopilus liquiritiae is a mushroom in the family Hymenogastraceae. The mushroom is widely distributed and grows in dense clusters on dead conifer wood. It has a rusty orange spore print, a bitter taste, and does not contain the hallucinogen psilocybin. One of its key distinguishing features is the lack of partial veil.
Psilocybe fimetaria is a psilocybin mushroom, having psilocybin and psilocin as main active compounds. It grows exclusively on horse and cow dung.
Mycena galericulata is a mushroom species commonly known as the common bonnet, the toque mycena, the common mycena or the rosy-gill fairy helmet. The type species of the genus Mycena was first described scientifically in 1772, but was not considered a Mycena until 1821. It is quite variable in color, size, and shape, which makes it somewhat difficult to reliably identify in the field. The mushrooms have caps with distinct radial grooves, particularly at the margin. The cap's color varies from grayish brown to dark brown and the shape ranges from bell-like to bluntly conical to flattened with an umbo. The stem is hollow, white, tough and thin, without a ring and often roots deeply into the wood on which it grows. The gills are white to grayish or even pinkish when mature and are connected by distinct cross-veins. The caps can reach 4 cm (1.6 in) in diameter, and have a mealy odor and taste. The spore print is white and the gills are pink at maturity, which can lead to possible confusion with species of the genus Pluteus. M. galericulata mushrooms grow mostly in clusters on the well-decayed stumps of deciduous and coniferous trees from spring to autumn. The species can generally be considered inedible. It is common and widespread in the entire temperate zone of the Northern Hemisphere, but it has also been reported from Africa.
Amanita onusta, commonly known as the loaded Lepidella, the gunpowder Lepidella or the gunpowder amanita, is a species of fungus in the mushroom family Amanitaceae. It is characterized by its small to medium-sized fruit bodies that have white to pale gray caps crowded with roughly conical, pyramidal, or irregular gray warts. The stipe is whitish-gray with woolly or wart-like veil remnants, and at the base is a spindle- or turnip-shaped base that is rooted somewhat deeply in the soil.
Amanita ravenelii, commonly known as the pinecone lepidella, is a species of fungus in the family Amanitaceae. The whitish fruit bodies are medium to large, with caps up to 17 centimetres wide, and stems up to 25 cm (10 in) long. The cap surface has large warts and the stem has a scaly, bulbous base. The mushrooms have a unique chlorine like odor.
Mycena maculata, commonly known as the reddish-spotted Mycena, is a species of fungus in the family Mycenaceae. The fruit bodies, or mushrooms, have conic to bell-shaped to convex caps that are initially dark brown but fade to brownish-gray when young, reaching diameters of up to 4 cm. They are typically wrinkled or somewhat grooved, and have reddish-brown spots in age, or after being cut or bruised. The whitish to pale gray gills also become spotted reddish-brown as they mature. The stem, up to 8 cm (3 in) long and covered with whitish hairs at its base, can also develop reddish stains. The mycelium of M. maculata has bioluminescent properties. The saprobic fungus is found in Europe and North America, where it grows in groups or clusters on the rotting wood of both hardwoods and conifers. The edibility of the fungus is unknown. Although the species is known for, and named after its propensity to stain reddish, occasionally these stains do not appear, making it virtually indistinguishable from M. galericulata.
Psilocybe pelliculosa is a species of fungus in the family Hymenogastraceae. The fruit bodies, or mushrooms, have a conical brownish cap up to 2 cm in diameter atop a slender stem up to 8 cm long. It has a white partial veil that does not leave a ring on the stem. American mycologist Alexander H. Smith first described the species in 1937 as a member of the genus known today as Psathyrella; it was transferred to Psilocybe by Rolf Singer in 1958.
Rhodocollybia butyracea, commonly known as the buttery collybia, is a species of fungus in the mushroom family Omphalotaceae. It has a number of subspecies.
