Pluteus cyanopus

Pluteus cyanopus 54538

Pluteus cyanopus is a species of fungus in the family Pluteaceae. It is known for its distinctive blue-staining properties and is found in various regions across the world. This species is often studied for its psychoactive properties due to the presence of psilocybin and psilocin.

Description

Pluteus cyanopus has a cap that ranges from 2 to 5 cm in diameter. The cap is initially convex, becoming broadly convex to flat with age. The color of the cap can vary from brown to grayish-brown, often with a bluish tint, especially towards the center. The surface of the cap is smooth and may become slightly sticky when moist.

The gills are free from the stem, closely spaced, and initially white, turning pink as the spores mature. The stem is 3 to 6 cm long and 0.3 to 0.8 cm thick, cylindrical, and often slightly curved. It is white to pale brown and may exhibit blue staining, especially when handled or damaged.

The spore print is pinkish-brown. Spores are smooth, ellipsoid, and measure 6-8 by 4-5 micrometers.

Habitat and Distribution

Pluteus cyanopus is a saprotrophic fungus, meaning it feeds on decaying organic matter. It is commonly found growing on decaying wood, including logs, stumps, and fallen branches. This species is typically found in temperate forests and woodlands.

Psychoactive Properties

Pluteus cyanopus contains the psychoactive compounds psilocybin and psilocin, which are known to cause hallucinations and altered states of consciousness. These compounds are of interest in the field of psychedelic research and have been studied for their potential therapeutic benefits.

Similar Species

Pluteus cyanopus can be confused with other species in the genus Pluteus, such as Pluteus salicinus and Pluteus cervinus. However, the blue-staining characteristic of P. cyanopus helps to distinguish it from other species.

Taxonomy

The species was first described by mycologist Rolf Singer in 1956. It belongs to the genus Pluteus, which includes many other wood-decaying fungi.
