Psilocybe cubensis a species of psychedelic mushroom whose principal active compounds are psilocybin and psilocin. Commonly called shrooms, magic mushrooms, golden tops, 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.
Psilocybe cubensis grows naturally in some areas of the U.S., throughout Central and South America, Southeast Asia, and Australia. They are so popular for home growing because they are relatively forgiving– even within the cubensis species, some specific strains have earned reputations as being particularly easy to grow.
While some mushroom strains can’t thrive in home grown settings without painstaking measure to accurately recreate their natural conditions, cubensis can grow well even in suboptimal conditions that are so common with amateur growing setups. They are also robust against changing conditions, while more sensitive strains might be damaged by a slight fluctuation in the environment.
