Psilocybe semilanceata

Psilocybe semilanceata, 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 distributed psilocybin mushrooms in nature, and one of the most potent.

Pileus (cap) of Psilocybe semilanceata

0.5-2.5 cm broad. Conic to obtuse conic to conic-campanulate with an acute umbo. Margin translucent-striate, incurved and sometimes undulated in young fruiting bodies. Often darkened by spores. Surface smooth, color variable, hygrophanous. Usually dark chestnut brown when moist. soon drying to a light tan or yellow, with an olive tint, margin sometimes with bluish or olive stains. Surface viscid when moist from a separable gelatinous pellicle.

Lamellae (Gills) of Psilocybe semilanceata

Attachment most adnexed, sometimes adnate or seceding. Close to crowded, narrow. Color pallid at first, rapid becoming grey. then brownish and finally purplish brown with the edges remaining pallid.

Stipe (stem) of Psilocybe semilanceata

30-100 mm long by 0.75-3 mm thick. Slender, equal, flexuous (curved or sinuous), and pliant. Pallid to more brownish towards the base. Where the attached mycelium may become bluish tinged, especially during drying. Surface smooth. Context stuffed with a fibrious pith. Partial veil thin cortinate, deteriorating, leaving an obscure evanescent annular zone of fibrils. usually darkened by spores. Often this zone is entire absent.

Microscopic features of Psilocybe semilanceata

Spores, Dark purplish brown in deposit, ellipsoid, 11-14 by 7-9 microns. Basidia 4-spored. Pleurocystidia few to absent. Cheilocystidia 18-35 by 4.5-8 microns. lageniform with an extended and flexuous neck, often forked.

Season of Psilocybe semilanceata

From when the fall rains begin until the first freezes. Liberty caps like cool temperatures, around 50 degrees Farenheit and lots of rain.

Habitat and Distribution of Psilocybe semilanceata

Psilocybe semilanceata grows in north temperate areas but it’s found in Peru. Pune, India, Australia, New Zealand. and also at altitudes of 4000 meters in Italy. Grows In fields where cattle graze, they will be in the larger greener clumps of grass. Or in parks and golf courses. They like the water that the plants funnel down to the base of the plant and tend to hide there.

Psilocybe strictipes:

Psilocybe strictipes is a psilocybin mushroom which grows on grassy meadows and lawns. It’s found throughout the cool temperate. And subarctic regions of the Northern Hemisphere and it is most common in Europe. And the Pacific Northwest. It is close related to Psilocybe semilanceata and Psilocybe pelliculosa. Psilocybe strictipes is common confused with Psilocybe semilanceata. and differentiated by its lack of a papilla and a convex to subumbonate cap. “Strictipes” comes from the Latin words stricti (narrow) and pes (foot).

Psilocybe liniformans var. americana:

Psilocybe liniformans var. americana is a very rare variant of liniformans that grows in America. It;s found scattered to gregarious in rich pastures or grasslands. fruiting from summer to early winter. Collected in Washington, Oregon, and Michigan. And has also reported from Chile where it fruits in the spring. This mushroom is very close to the type variety. The main difference is the lack of a gelatinous layer on the edge of the lamellae. And the terricolous habitat.
