Blue Meanie is a popular and potent variety of Psilocybe cubensis, named for its strong blue bruising reaction when handled. The mushrooms typically feature medium-sized golden caps and thick white stems that show deep blue coloration under pressure.

In user reports, Blue Meanies are said to offer a more intense psilocybin experience than many other cubensis strains, often producing vivid visuals, heightened euphoria, and strong introspection. Despite their strength, many note a clear-headed and energetic quality, making them a favorite among experienced psychonauts.
