Cordyceps is a genus of ascomycete fungi that includes about 600 worldwide species. Diverse variants of cordyceps have had more than 1,500 years of use in Chinese medicine. Most Cordyceps species are endoparasitoids, parasitic mainly on insects and other arthropods ; a few are parasitic on other fungi.
The Clavicipitaceae are a family of fungi within the order Hypocreales. A 2008 estimate placed 43 genera in the family, but a study in 2020 has increased this number to 50.
Beauveria is a genus of asexually-reproducing fungi allied with the ascomycete family Cordycipitaceae. Its several species are typically insect pathogens. The sexual states (teleomorphs) of Beauveria species, where known, are species of Cordyceps.
Metarhizium is a genus of entomopathogenic fungi in the Clavicipitaceae family. With the advent of genetic profiling, placing these fungi in proper taxa has now become possible. Most turn out to be the asexual forms (anamorphs) of fungi in the phylum Ascomycota, including Metacordyceps spp.
Hirsutella is a genus of asexually reproducing fungi in the Ophiocordycipitaceae family. Originally described by French mycologist Narcisse Théophile Patouillard in 1892, this genus includes species that are pathogens of insects, mites and nematodes; there is interest in the use of these fungi as biological controls of insect and nematode pests. The teleomorphs of Hirsutella species are thought to belong to the genus Ophiocordyceps.
Ascopolyporus is a genus of fungi within the family Cordycipitaceae. Species are pathogens of scale insects.
Metacordyceps is a genus of fungi in the family Clavicipitaceae. The anamorphs of Metacordyceps appear to include Metarhizium species.
Ophiocordyceps is a genus of fungi within the family Ophiocordycipitaceae. The widespread genus, first described scientifically by British mycologist Tom Petch in 1931, contains about 140 species that grow on insects. Anamorphic genera that correspond with Ophiocordyceps species are Hirsutella, Hymenostilbe, Isaria, Paraisaria, and Syngliocladium.
Podonectria is a genus in the monotypic Podonectriaceae family of fungi. They are parasitic fungus on scale insects, other fungi, or on substrates that had previously colonized by other fungi.
Lecanicillium lecanii is now an approved name of an entomopathogenic fungus species, that was previously widely known as Verticillium lecanii (Zimmerman) Viegas), but is now understood to be an anamorphic form in the Cordyceps group of genera in the Clavicipitaceae. Isolates formerly classified as V. lecanii could be L. attenuatum, L. lecanii, L. longisporum, L. muscarium or L. nodulosum. For example, several recent papers, such as Kouvelis et al. who carried out mitochondrial DNA studies, refer to the name L. muscarium.
Purpureocillium is a fungal genus in the Ophiocordycipitaceae family. The genus now contains at least 5 species with the type species Purpureocillium lilacinum, a common saprobic, filamentous fungus. It has been isolated from a wide range of habitats, including cultivated and uncultivated soils, forests, grassland, deserts, estuarine sediments and sewage sludge, and insects. It has also been found in nematode eggs, and occasionally from females of root-knot and cyst nematodes. In addition, it has frequently been detected in the rhizosphere of many crops. The species can grow at a wide range of temperatures – from 8 to 38 °C for a few isolates, with optimal growth in the range 26 to 30 °C. It also has a wide pH tolerance and can grow on a variety of substrates. P. lilacinum has shown promising results for use as a biocontrol agent to control the growth of destructive root-knot nematodes.
Hymenostilbe is a genus of fungi in the Ophiocordycipitaceae family. All members are anamorph names of Ophiocordyceps.
Paraisaria is a genus of fungi in the Ophiocordycipitaceae family. Members are anamorph names of Ophiocordyceps.
Syngliocladium is a genus of anamorphic fungi within the Ophiocordycipitaceae family. Members are anamorph names of Ophiocordyceps.
Tolypocladium is a genus of fungi within the family Ophiocordycipitaceae. It includes species that are parasites of other fungi, insect pathogens, rotifer pathogens and soil inhabiting species with uncertain ecological roles. Tolypocladium was originally circumscribed as a genus containing anamorphic fungi. It was later determined that some Cordyceps-like teleomorphic fungi were the teleomorphs of Tolypocladium species. These species were considered to belong in the genus Cordyceps until molecular phylogenetics studies found these species to be more closely related to Ophiocordyceps and were considered to belong in that genus before they were transferred to the new genus Elaphocordyceps by Sung and colleagues in 2007. However, under the ICN's 2011 "one fungus, one name" principle, fungi can not have different names for their anamorphic and teleomorphic stages if they are found to be the same taxon. Quandt and colleagues formally synonymized Tolypocladium and Elaphocordyceps in 2014. Quandt and colleagues also synonymized the anamorphic genus Chaunopycnis with Tolypocladium. The immunosuppressant drug ciclosporin was originally isolated from Tolypocladium inflatum, and has since been found in other species of Tolypocladium, some of which were formerly placed in Chaunopycnis.
Ophiocordyceps myrmecophila is a species of fungus that parasitizes insect hosts, in particular members of the order Hymenoptera.
Tolypocladium ophioglossoides, also known by two of its better known synonyms Elaphocordyceps ophioglossoides and Cordyceps ophioglossoides and commonly known as the goldenthread cordyceps, is a species of fungus in the family Ophiocordycipitaceae. It is parasitic on fruit bodies of the truffle-like Elaphomyces. The specific epithet ophioglossoides, derived from Ancient Greek, means "like a snake's tongue". The species is thought to be inedible by people in the Western hemisphere, however, Traditional Chinese medicine of the Eastern Hemisphere recognizes T. ophioglossoides as a valuable medicinal fungi.
The Cordycipitaceae are a family of parasitic fungi in the Ascomycota, class Sordariomycetes and order Hypocreales. The family was first published in 1969 by mycologist Hanns Kreisel, but the naming was invalid according to the code of International Code of Nomenclature for algae, fungi, and plants. It was validly published in 2007.
Ophiocordyceps formicarum is an entomopathogenic fungus belonging to the order Hypocreales (Ascomycota) in the family Ophiocordycipitaceae. The fungus was first described by mycologist George S. Kobayashi in 1939 as a species of Cordyceps. Originally found in Japan growing on an adult Hercules ant, it was reported from Guizhou, China, in 2003. It was transferred to the new genus Ophiocordyceps in 2007 when the family Cordycipitaceae was reorganized. A technique has been developed to grow the fungus in an agar growth medium supplemented with yeast extract, inosine, and glucose.
Ophiocordyceps robertsii, known in New Zealand as vegetable caterpillar is an entomopathogenic fungus belonging to the order Hypocreales (Ascomycota) in the family Ophiocordycipitaceae. It invades the caterpillars of leaf-litter dwelling moths and turns them into fungal mummies, sending up a fruiting spike above the forest floor to shed its spores. Caterpillars eat the spores whilst feeding on leaf litter to complete the fungal life cycle. Evidence of this fungus can be seen when small brown stems push through the forest floor: underneath will be the dried remains of the host caterpillar. This species was first thought by Europeans to be a worm or caterpillar that burrowed from the top of a tree to the roots, where it exited and then grew a shoot of the plant out of its head. It was the first fungus provided with a binomial name from New Zealand.
