Inocybe aeruginascens

Inocybe aeruginascens is a species of mushroom belonging to the genus Inocybe. It is known for its psychoactive properties due to the presence of compounds such as psilocybin, psilocin, and bæocystin. This mushroom is found in various parts of Europe and Asia, often growing in grassy areas near deciduous trees.

Description

Inocybe aeruginascens features a conical to bell-shaped cap, which can reach up to 5 cm in diameter. The cap is typically brown to olive in color, often with a greenish tint, and becomes more bell-shaped as it matures. The gills are crowded, and their color ranges from light gray to brownish. The stem of the mushroom is slender, measuring up to 8 cm in height, and it may display a bluish-green coloration towards the base, especially when handled or bruised.

Habitat and Distribution

This species prefers calcareous soil and is commonly found in grasslands, parks, and gardens, particularly in association with deciduous trees such as oak and hazel. Inocybe aeruginascens has a widespread distribution in Europe, with occurrences also reported in Asia. It fruits from late summer to autumn.

Psychoactive Properties

Inocybe aeruginascens contains several psychoactive alkaloids, including psilocybin, psilocin, and bæocystin, which are responsible for its hallucinogenic effects. These substances interact with serotonin receptors in the brain, leading to altered perceptions, mood changes, and, in some cases, visual and auditory hallucinations. Due to its psychoactive compounds, this mushroom is of interest in the study of psychedelic substances and their potential therapeutic applications.

Toxicity and Identification

While Inocybe aeruginascens is sought after by some for its psychoactive effects, it is important to note that many species within the Inocybe genus are highly toxic, containing dangerous levels of muscarine. Accurate identification is crucial, as mistaking a toxic Inocybe species for I. aeruginascens can result in severe poisoning. Symptoms of muscarine poisoning include excessive salivation, sweating, and severe gastrointestinal distress. Therefore, foraging for this mushroom should be done with extreme caution and preferably under the guidance of an experienced mycologist.

Legal Status

The legal status of Inocybe aeruginascens varies by country, largely due to its psilocybin content. In many jurisdictions, the possession, sale, and cultivation of psilocybin-containing mushrooms are regulated or prohibited by law.
