Psilocybe cubensis grows naturally in tropical and subtropical conditions, often near cattle due to the ideal conditions they provide for the growth of the fungus. The cow usually consumes grains or grass covered with the spores of Psilocybe cubensis and the fungus will begin to germinate within the dung.
[50] [1] Psilocybe cubensis, the most popular species, has been reported to contain 0.63% psilocybin and 0.6% psilocin, or about 1.2% of psilocybin and psilocin combined. [50] However, there is significant variation in different P. cubensis strains. [54] [55] The 'Penis Envy' strain of P. cubensis is considered to be more potent than other ...
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. [56]
There are over 100 psychoactive mushroom species of genus Psilocybe native to regions all around the world. [47] Psilocybin, a naturally occurring chemical in certain psychedelic mushrooms such as Psilocybe cubensis, is being studied for its ability to help people suffering from psychological disorders, such as obsessive–compulsive disorder.

The stoned ape theory is a controversial hypothesis first proposed by American ethnobotanist and mystic Terence McKenna in his 1992 book Food of the Gods.
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.
