Psilocybe guilartensis

Psilocybe guilartensis Guzm%C3%A1n (151401)

Psilocybe guilartensis is a species of psilocybin mushroom in the family Hymenogastraceae. This species is known for its psychoactive properties, which are primarily due to the presence of psilocybin and psilocin.

Taxonomy and Naming

The species was first described by mycologist Gaston Guzman in 1978. The specific epithet guilartensis refers to the Guilarte Forest in Puerto Rico, where the type specimen was collected.

Description

Cap

The cap of Psilocybe guilartensis is typically conical to convex, measuring 1-3 cm in diameter. It is hygrophanous, changing color as it loses moisture, and can range from a dark brown when moist to a lighter tan or yellowish color when dry.

Gills

The gills are adnate to adnexed, closely spaced, and initially a light brown color, becoming darker as the spores mature.

Stipe

The stipe (stem) is slender, measuring 3-8 cm in length and 0.1-0.3 cm in thickness. It is typically the same color as the cap or slightly lighter and may exhibit a bluish bruising reaction when handled.

Spores

The spores are dark purplish-brown, ellipsoid, and measure 10-13 by 6-8 micrometers.

Habitat and Distribution

Psilocybe guilartensis is primarily found in tropical and subtropical regions. It grows on decaying wood, particularly in humid forest environments. The species has been reported in Puerto Rico, Mexico, and other parts of Central America.

Psychoactive Properties

The psychoactive effects of Psilocybe guilartensis are due to the presence of psilocybin and psilocin, which are known to cause hallucinations, altered perception of time, and changes in mood. These compounds interact with serotonin receptors in the brain, leading to their psychoactive effects.

Legal Status

The legal status of Psilocybe guilartensis varies by country. In many places, the possession, sale, and use of psilocybin-containing mushrooms are regulated or prohibited.
