Species[1]

Cordyceps is a genus of ascomycete fungi (sac fungi) that includes about 600 worldwide species. Diverse variants of cordyceps have had more than 1,500 years of use in Chinese medicine.[2] Most Cordyceps species are endoparasitoids, parasitic mainly on insects and other arthropods (they are thus entomopathogenic fungi); a few are parasitic on other fungi.[3]

The generic name Cordyceps is derived from the ancient Greek κορδύλη kordýlē, meaning "club", and the Latin -ceps, meaning "-headed".[4] The genus has a worldwide distribution, with most of the approximately 600 known species[5] being from Asia (notably Nepal, China, Japan, Bhutan, Korea, Vietnam, and Thailand).

Taxonomy[edit | edit source]

There are two recognized subgenera:[6]

  • Cordyceps subgen. Cordyceps Fr. 1818[7]
  • Cordyceps subgen. Cordylia Tul. & C. Tul. 1865[8]

Cordyceps sensu stricto are the teleomorphs of a number of anamorphic, entomopathogenic fungus "genera" such as Beauveria (Cordyceps bassiana), Septofusidium, and Lecanicillium.[9]

Splits[edit | edit source]

Cordyceps subgen. Epichloe was at one time a subgenus, but is now regarded as a separate genus, Epichloë.[6]

Cordyceps subgen. Ophiocordyceps was at one time a subgenus defined by morphology. Nuclear DNA sampling done in 2007 shows that members, including "C. sinensis" and "C. unilateralis", as well as some others not placed in the subgenus, were distantly related to most of the remainder of species then placed in Cordyceps (e.g. the type species C. militaris). As a result, it became its own genus, absorbing new members.[9][10]

The 2007 study also peeled off Metacordyceps (anamorph Metarhizium, Pochonia) and Elaphocordyceps. A number of species remain unclearly assigned and provisionally retained in Cordyceps sensu lato.[9]

Biology[edit | edit source]

When Cordyceps attacks a host, the mycelium invades and eventually replaces the host tissue, while the elongated fruit body (ascocarp) may be cylindrical, branched, or of complex shape. The ascocarp bears many small, flask-shaped perithecia containing asci. These, in turn, contain thread-like ascospores, which usually break into fragments and are presumably infective.[11]

Research[edit | edit source]

Polysaccharide components and cordycepin are under basic research and have been isolated from C. militaris.[12]

Uses[edit | edit source]

Along with Ophiocordyceps, Cordyceps has long been used in traditional Chinese medicine in the belief it can be used to treat diseases.[13] There is no strong scientific evidence for such uses.[12]
