Psilocybe strictipes is a species of psilocybin mushroom in the family Hymenogastraceae. It is closely related to Psilocybe semilanceata and Psilocybe mexicana. This species is known for its psychoactive properties, primarily due to the presence of psilocybin and psilocin.

Description

Psilocybe strictipes has a conical to bell-shaped cap that measures 1–2 cm in diameter. The cap is hygrophanous, meaning it changes color depending on its moisture content, typically ranging from a dark chestnut brown when moist to a pale yellow-brown when dry. The surface of the cap is smooth and sticky when moist.

The gills are adnate to adnexed, close, and initially pale brown, becoming dark purple-brown with age as the spores mature. The stipe (stem) is slender, measuring 4–10 cm in length and 1–2 mm in thickness, and is typically the same color as the cap or slightly lighter. The stipe is often curved and has a fibrous texture.

The spore print is dark purple-brown. Microscopically, the spores are ellipsoid, smooth, and measure 12–14 by 7–8 µm.

Habitat and Distribution

Psilocybe strictipes is commonly found in temperate regions, particularly in Europe and North America. It typically grows in grassy areas, such as lawns, meadows, and pastures, often in association with decaying organic matter. This species is most commonly found during the autumn months.

Psychoactive Properties

Psilocybe strictipes contains the psychoactive compounds psilocybin and psilocin, which are responsible for its hallucinogenic effects. These compounds interact with serotonin receptors in the brain, leading to altered perceptions, mood changes, and visual hallucinations. The potency of Psilocybe strictipes can vary, but it is generally considered to be less potent than Psilocybe cubensis.

Legal Status

The legal status of Psilocybe strictipes varies by country. In many places, the possession, sale, and use of psilocybin-containing mushrooms are illegal. However, some countries and regions have decriminalized or legalized the use of these mushrooms for medical or recreational purposes.
