ergot  (ûrgt)

A fungus (Claviceps purpurea) that infects rye as well as other cereal grasses fed to livestock. Ergot forms sclerotia (masses of hyphae) that replace individual seeds in the spike of the infected plant and contain a complex mixture of alkaloids, several of which are medicinally important. Ergot is the basic source of ergotamine and lysergic acid. Ingestion of infected rye produces convulsions, hallucinations, and severe vasoconstriction that can lead to gangrene. Ergot poisoning may have been responsible for outbreaks of mass hysteria and reports of demonic visions in medieval Europe.
