Psilocybe semilanceata

Psilocybe semilanceata, commonly known as the liberty cap, is a type of wild mushroom containing psilocybin, a naturally occurring psychedelic substance. These mushrooms are small, with a distinctive bell-shaped cap and a slender stem, often found in grassy areas like pasturelands. When ingested, psilocybin converts in the body to psilocin, which can cause altered perception, visual and mental changes, and hallucinations. They have been used historically in spiritual or shamanic rituals. However, they are illegal in many areas due to their psychoactive effects and potential risks, including confusion, anxiety, and other adverse reactions.
