Known by numerous names— Liberty Caps , Blue Legs, Pixie Caps, Witches Hats— Psilocybe semilanceata is an unassuming innocent-looking mushroom, often happily growing next to many similar species, including Panaeolus spp. and Protostropharia semiglobata . Like Psilocybe cubensis, Liberty Caps grow in fields and pastures, but prefer the cold of temperate climates. Found growing in fall and spring, these delicate-looking, slender mushrooms are among the most potent Psilocybe species.
