illbilly mushrooms are a cultivated variety of magic mushrooms—a variation of the Psilocybe cubensis fungus. P. cubensis is the most common species of magic mushrooms, known for its unfussy growing habits and fun, gentle trips. Like with many magic mushroom varieties, interest in the stout-stemmed Hillbilly has waxed and waned over the past two decades—although it enjoyed a distinct moment in the limelight after winning the Hyphae Cup microdose category in Spring 2022. Hyphae Labs, which runs the Hyphae Cup, operates in Oakland, where psilocybin mushrooms are decriminalized.
