The genus Claviceps is a group of fungi that are known for producing ergot alkaloids. These alkaloids have been used for centuries for medicinal purposes, but they can also be poisonous in large amounts. Claviceps is commonly referred to as Ergot, a term that is used interchangeably with the genus. Other synonyms include Sphacelia, which is a term used to describe the soft, spongy mass of spores produced by the fungus, and Acremonium, a genus that is closely related to Claviceps. Despite the potential dangers associated with ergot alkaloids, Claviceps species continue to be of interest to researchers for their potential therapeutic uses.
