Psilocybe cubensis is a species of psychedelic mushroom whose principal active compounds are psilocybin and psilocin. Commonly called shrooms, magic mushrooms, golden halos, cubes, or gold caps, it belongs to the fungus family Hymenogastraceae and was previously known as Stropharia cubensis. It is the most well known psilocybin mushroom due to its wide distribution and ease of cultivation. buy amazonian psilocybe cubensis
The cap is 1.6–8 cm (0.6–3.1 in), conic to convex with a central papilla when young, becoming broadly convex to plane with age, retaining a slight umbo sometimes surrounded by a ring-shaped depression. The cap surface is smooth and sticky, sometimes with white universal veil remnants attached. The cap is brown becoming paler to almost white at the margin, and fades to more golden-brown or yellowish with age. When bruised, all parts of the mushroom stain blue. The narrow grey gills are adnate to adnexed, sometimes seceding attachment, and darken to purplish-black and somewhat mottled with age. The gill edges remain whitish. The hollow white stipe is 4–15 cm (2–6 in) high by 0.4–1.4 cm (0.2–0.6 in) thick, becoming yellowish in age. The well-developed veil leaves a persistent white membranous ring whose surface usually becomes the same colour as the gills because of falling spores. The mushroom has no odor, and tastes farinaceous. The spores are 11.5–17.3 x 8–11.5 µm, subellipsoid, basidia 4-spored but sometimes 2- or 3-, pleurocystidia and cheilocystidia present.
The related species Psilocybe subcubensis—found in tropical regions—is indistinguishable but has smaller spores. buy amazonian psilocybe cubensis
