Of particular interest is the cattle egret (Bubulcus ibis), a colonizer of Old World origin (via South America), whose range of distribution overlaps much of that of Psilocybe cubensis. Cattle egrets typically walk alongside cattle, preying on insects; they track through spore-laden vegetation and cow dung and transfer the spores to suitable ...
Usual doses of the common species Psilocybe cubensis range around 1.0 to 2.5 g, while about 2.5 to 5.0 g dried mushroom material is considered a strong dose. [45] Above 5 g is often considered a heavy dose, with 5.0 grams of dried mushroom often being referred to as a "heroic dose". [46] [47]
In 2007, a paper by Redhead et al. proposed conserving the genus Psilocybe with Psilocybe semilanceata as its type species. [5] The suggestion was accepted by unanimous vote of the Nomenclature Committee for Fungi of the International Botanical Congress in 2010, meaning that P. semilanceata (a member of the bluing clade) now serves as the type species of the genus.

Psilocybin comprises approximately 1% of the weight of Psilocybe cubensis mushrooms, and so nearly 1.7 kilograms (3.7 lb) of dried mushrooms, or 17 kilograms (37 lb) of fresh mushrooms, would be required for a 60-kilogram (130 lb) person to reach the 280 mg/kg LD 50 value of rats. [46]
Panaeolus cinctulus, syn. Panaeolus subbalteatus, commonly known as the banded mottlegill, weed Panaeolus, belted panaeolus, [3] or subbs is a very common, widely distributed psilocybin mushroom.
Psilocybe cubensis liniformans var. americana is found scattered to gregarious in rich pastures or grasslands, fruiting from summer to early winter. It has been collected in Washington, Oregon, and Michigan, and has also been reported from Chile where it fruits in the spring.
Psilocybe ovoideocystidiata is a psilocybin mushroom, having psilocybin and/or psilocin as main active compounds. It is closely related to P. subaeruginascens from Java , P. septentrionalis from Japan , and P. wayanadensis from India .
