Liberty Caps Mushroom
Liberty Caps mushroom scienfically called Psilocybe semilanceata, commonly known as the liberty cap, is a species of fungus which produces the psychoactive compounds psilocybin and baeocystin.
It is both one of the most widely distributed psilocybin mushrooms in nature, and one of the most potent. The mushrooms have a distinctive conical to bell-shaped cap, up to 2.5 cm (1 in) in diameter, with a small nipple-like protrusion on the top.
They are yellow to brown, covered with radial grooves when moist, and fade to a lighter color as they mature.
Psychoactive alkaloid content
This species contains the compound psilocybin. Because this substance, which occurs in Magic Mushrooms and some related fungi, occasionally causes alarming symptoms including vomiting, stomach pains and anxiety attacks, Liberty Caps mushroom are probably best treated with caution (some people even decide to treat them as poisonous).
