fungal disease of rye and other grasses, 1680s, from French ergot "ergot," also "a spur, the extremity of a dead branch," from Old French argot "cock's spur" (12c.), which is of unknown origin.

Wikipedia
Ergot

Ergot (pron. ) or ergot fungi refers to a group of fungi of the genus Claviceps.

The most prominent member of this group is Claviceps purpurea ("rye ergot fungus"). This fungus grows on rye and related plants, and produces alkaloids that can cause ergotism in humans and other mammals who consume grains contaminated with its fruiting structure (called ergot sclerotium).

Claviceps includes about 50 known species, mostly in the tropical regions. Economically significant species include C. purpurea (parasitic on grasses and cereals), C. fusiformis (on pearl millet, buffel grass), C. paspali (on dallis grass), C. africana (on sorghum), and "C. Lutea'' (on paspalum). C. purpurea'' most commonly affects outcrossing species such as rye (its most common host), as well as triticale, wheat and barley. It affects oats only rarely.

C. purpurea has at least three races or varieties, which differ in their host specificity:

  • G1 — land grasses of open meadows and fields;
  • G2 — grasses from moist, forest, and mountain habitats;
  • G3 (C. purpurea var. spartinae) — salt marsh grasses (Spartina, Distichlis).
Ergot (horse anatomy)

The ergot is a small callosity on the underside of the fetlock of a horse or other equine. Some equines have them on all four fetlocks; others have few or no detectable ergots. In horses, the ergot varies from very small to the size of a pea or bean, larger ergots occurring in horses with " feather" – long hairs on the lower legs. In some other equines, the ergot can be as much as in diameter.

Ergot comes from the French word for rooster's spur.
