context_page_description: Claviceps purpurea is an ergot fungus that grows on the ears of rye and related cereal and forage plants. Consumption of grains or seeds contaminated with the survival structure of this fungus, the ergot sclerotium, can cause ergotism in humans and other mammals. C. purpurea most commonly affects outcrossing species such as rye, as well as triticale, wheat and barley. It affects oats only rarely.
context_section_description: Potato dextrose agar, wheat seeds or oat flour are suitable substrates for growth of the fungus in the laboratory.
  Agricultural production of Claviceps purpurea on rye is used to produce ergot alkaloids. Biological production of ergot alkaloids is also carried out by saprophytic cultivations.
