er·got

(er'got),
The resistant, overwintering stage of the parasitic ascomycetous fungus Claviceps purpurea, a pathogen of cereal rye that transforms the seed of rye into a compact spurlike mass of fungal pseudotissue (the sclerotium) containing five or more optically isomeric pairs of alkaloids. The levorotary isomers induce uterine contractions, control bleeding, and alleviate certain localized vascular disorders (migraine headaches).

ergot

One of various fungi of the genus Claviceps , that can grow on rye and other cereal plants and cause the serious condition of ERGOTISM by virtue of its alpha-adrenoceptor stimulating action. Ergot is the source of various valuable drugs such as ERGOTAMINE and ERGOMETRINE. It is also the source of lysergic acid.
