Psilocybe semilanceata, also known as Liberty Cap, is a hallucinogenic mushroom that contains the psychoactive compounds psilocybin. It has a distinctive yellowish conical to bell-shaped cap with a small nipple-like protrusion on the top. The mushroom grows in scattered trooping groups, on soil amongst the grass in lawns and pastures favouring hilly sites.
hygrophanous, meaning it changes colour based on moisture. When moist, it ranges from ochraceous to dark chestnut brown, often with a greenish-blue tinge. Radial lines are visible when moist. When dry, it turns pale yellow-brown. It varies in shape from sharply conical to bell-shaped, often with a prominent papilla. It does not change shape considerably as it ages. The cap margin is initially rolled inward but unrolls to become straight or even curled upwards in maturity. Gills
moderately crowded together, and they have a narrowly adnexed to almost free attachment to the stem. They are olive-grey, to begin with, but turn purple-black as the spores mature. Stem
slender, yellowish-brown and usually slightly thicker towards the base. The mushroom has a thin cobweb-like partial veil that does not last long before disappearing. Sometimes, the partial veil leaves an annular zone on the stipe that may be darkened by spores. Spore print
very dark purple-brown.
The spores are ellipsoidal in shape and have a smooth surface. They measure 11.5-14.5 9μm in length and 7-9 9μm in width.

Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we recommend that you never eat wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.
