Psilocybe semilanceata, commonly known as the liberty cap, is a species of fungus which produces psilocybin, psilocin and baeocystin. It is one of the most widely distributed psilocybin mushrooms in nature. 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. Their stipes tend to be slender and long, and the same color or slightly lighter than the cap.
