The Liberty Cap mushroom (Psilocybe semilanceata), the most common psychedelic fungus in Britain, gets its name from an ancient Roman social practice.

Pathogenic projectiles called waawî among the Makushi people of Guyana are ambiguous entities that are both objects and beings. Fabricated by shamans as embodiments of spirit-helpers, these magical darts exist beyond conventional distinctions between nature and culture.
