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).

Description

Psilocybe strictipes has a farinaceous smell and taste. Pleurocystidia are absent and its lageniform cheilocystidia are 21-45 by 7-10 μm. The cap is 5 to 30 mm across, conic to campanulate to convex, smooth, and translucent-striate near the margin, often with a low umbo. It is walnut brown to dark rusty brown, with a smooth surface and a separable gelatinous pellicle. It is Hygrophanous, fading to buff as it dries. The flesh sometimes stains blue where damaged. The gills are cream-colored when young and dark purple brown when mature, with an adnate attachment. The spores are dark purple brown, suboblong, and 11 by 6 μm. The stipe has a white to ocher, equal, tough, and cartilaginous structure with fibrillose patches. It is 4 to 10 cm long and around .25 cm thick. The partial veil is thin, cortinate, and does not usually leave any remnants on the stipe.

Distribution and habitat

Psilocybe strictipes fruits in late summer to fall in Chile, England, Scotland, France, Germany, the Netherlands, Poland, Slovakia, Sweden, Siberia, and the Pacific Northwest. Psilocybe strictipes is found in lawns and grassy fields but never growing directly from dung.

<i>Psilocybe semilanceata</i> Species of fungus in the family Hymenogastraceae, native to Europe

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.

<i>Psilocybe tampanensis</i> Psychedelic mushroom in the family Hymenogastraceae

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.

It was given its current name by mycologist Rolf Singer in 1951.

<i>Psilocybe atlantis</i> Species of fungus

<i>Psilocybe hispanica</i> Species of fungus in the family Hymenogastraceae

Psilocybe hispanica is a species of fungus in the family Hymenogastraceae. It produces small brown mushrooms with conical to convex caps up to 10 mm (0.4 in) in diameter and stems 16 to 25 mm long by 0.5 to 1 mm thick. Reported as new to science in 2000, it is only known from the Pyrenees mountain range in northern Spain and southwestern France, where it grows on horse dung in grass fields at elevations of 1,700 to 2,300 m. The mushroom contains the psychoactive compound psilocybin. The possible depiction of this species in the 6,000-year-old Selva Pascuala rock art suggests that it might have been used in ancient religious rituals—the oldest evidence of such usage in prehistoric Europe.
