Genetic Background:

The McKennaii strain is a variant of Psilocybe cubensis, distinguished by its enigmatic history and its homage to Terence McKenna’s groundbreaking work in the field of psychedelics. While rumors about its origin circulate—ranging from being developed from spore prints in McKenna’s collection to being named for its potent effects as a marketing strategy—what’s undeniable is the McKennaii’s unique place in the pantheon of magic mushrooms. This strain is reputedly related to the Golden Teacher variety, yet it carries its own distinct characteristics and a potentially stronger effect.


McKennaii mushrooms are celebrated for their intermediate to high potency. This strain provides a robust psychedelic experience characterized by euphoria, wonder, and deep introspection. Users report a gradual onset that escalates into a profound exploration of the psyche, making McKennaii a choice for those seeking a journey into self-reflection and connection with the environment.

Growth Characteristics:

McKennaii mushrooms are known for their versatility in growing mediums, thriving on substrates like rye, millet, birdseed, and popcorn. They favor conditions that mimic their natural habitat, with growers often utilizing a blend of coco coir, vermiculite, and gypsum to simulate the dung-loving conditions they prefer. This strain is lauded for its ease of cultivation, rapid colonization, and the ability to produce several flushes, making it accessible to both novice and experienced cultivators.


Medium to large in size, McKennaii mushrooms can be identified by their light to dark brown caps and thick stems. Their caps exhibit a classic Psilocybe cubensis curvature, but with a distinctiveness that sets them apart from other strains. The spores are dark, almost purplish, adding to the visual appeal of this intriguing variety.

Historical Significance:

Named in honor of Terence McKenna, the McKennaii strain embodies the spirit of exploration and understanding that McKenna promoted. Its introduction to the psychedelic community has added a layer of depth to the ongoing conversation about the therapeutic and spiritual uses of psilocybin mushrooms, making it a strain that’s as much about its effects as it is about its contribution to psychedelic culture.
