Psilocybe semilanceata Magic Mushrooms

Psilocybe semilanceata : Background

The first recorded case of the ingestion of the psilocybe semilanceata (Liberty Cap) was in London in 1799. A family had picked some mushrooms in a park for their food. After consuming the mushrooms, their pupils dilated, and they went into a state of delirium.

In 1960, mycologist Albert Hoffman established that the psilocybin components in the mushrooms were responsible.

Psilocybe semilanceata : Physical Description


Bell-like, conical-shaped caps. The shape of the caps remains the same throughout the lifetime of the mushroom. The cap margin (edge) is rolled in for the younger liberty caps but unrolls to become straight and in some cases, the margins even roll upwards as the mushroom matures.


Psilocybe Semilanceata have 15-27 narrow and moderately spaced gills. Each gill is independently and freely attached to the stem. The gills are initially pale brown, but they become darker purple-brown as the mushroom matures.
