Clavicipitaceae is a family of fungi within the order Hypocreales. It consists of 43 genera, and 321 species.[1]

Phylogeny[edit]

Molecular phylogenetic analysis of multigene DNA sequence data indicates that the taxon, Clavicipitaceae, is paraphyletic, and consists of three well-defined clades, at least one of which is shared with members of another fungal family (Hypocreaceae).[2] The evolution within the Clavicipitaceae is marked by interkingdom host jumping, and the range of this large and heterogeneous fungal group spans mutualistic plant symbionts as well as parasites of plants, insects, and other fungi.[3]

Significance[edit]

Many of its members produce alkaloids toxic to animals and humans. One of its most infamous species is Claviceps purpurea, which has historical significance as the cause of St. Anthony's Fire, also known as ergotism. Ergotism is caused by ergot alkaloids, such as ergotamine and ergocristine, which are chemical derivatives of lysergic acid. Ciclosporin, a drug used in transplant surgery, is derived from Tolypocladium inflatum, the anamorph of Cordyceps subsessilis. Cordyceps sinensis is highly valued in Traditional Chinese Medicine. Species of Beauveria and Metarhizium are widely used in the biological control of insect pests.
