Psilocybe fimetaria

FimeteriA

Psilocybe fimetaria 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.

Description

Psilocybe fimetaria has a distinctive appearance that makes it identifiable among other species of psilocybin mushrooms. The cap is typically 1.5 to 4 cm in diameter, conical to convex in shape, and often has a slight umbo. The color of the cap ranges from a yellowish-brown to a darker brown, often with a hygrophanous nature, meaning it changes color as it loses moisture. The gills are adnate to adnexed, and they start out pale brown, becoming darker as the spores mature. The stipe, or stem, is 3 to 7 cm long, slender, and often has a slight swelling at the base. It is usually the same color as the cap or slightly lighter.

Habitat and Distribution

Psilocybe fimetaria is commonly found in temperate regions, particularly in Europe and North America. It typically grows in manure-rich soil, often in pastures and fields where livestock are present. The fruiting bodies appear in late summer to early autumn, depending on the climate and environmental conditions.

Psychoactive Compounds

The primary psychoactive compounds in Psilocybe fimetaria are psilocybin and psilocin. These compounds are known to produce hallucinogenic effects when ingested. The intensity and duration of the effects can vary based on the dosage, the individual's metabolism, and other factors.

Legal Status

The legal status of Psilocybe fimetaria varies by country and region. In many places, the possession, sale, and use of psilocybin mushrooms are regulated or prohibited due to their psychoactive properties. It is important to be aware of local laws and regulations regarding these substances.

Similar Species

Psilocybe fimetaria can be confused with other species of psilocybin mushrooms, such as Psilocybe cubensis and Psilocybe semilanceata. Careful examination of the morphological features and habitat can help in accurate identification.
