A fungus or mushroom, especially one used historically for medicine or in religious rituals, or any fungus with a gill structure underneath.
From Greek 'agarikon' through Latin, originally referring to a medicinal fungus from Dacia (modern Romania). The term evolved to mean various fungi and mushrooms.
Medieval physicians thought agarics had magical healing powers and used them in medicines—some people even believed certain agarics could make people prophetic or give them visions, mixing medicine with mysticism!
