Cordyceps is a genus of ascomycete fungi (sac fungi) that includes about 400 identified species and many yet to be described. All Cordyceps species are endoparasitoids, mainly on insects and other arthropods (they are thusentomopathogenic fungi); a few are parasitic on other fungi. The best known species of the genus is Cordyceps sinensis,[1] first recorded as yartsa gunbu in Tibet in the 15th Century.[2] It is known as yarsha gumba in Nepal. The Latin etymology describes cord as club, ceps as head, and sinensis as Chinese. Cordyceps sinensis, known in English commonly as caterpillar fungus, is considered a medicinal mushroom in oriental medicines, such astraditional Chinese medicines[3][unreliable source?] and traditional Tibetan medicine.
When a Cordyceps fungus attacks a host, the mycelium invades and eventually replaces the host tissue, while the elongated fruiting 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.
Some Cordyceps species are able to affect the behavior of their insect host: Cordyceps unilateralis causes ants to climb a plant and attach there before they die. This ensures the parasite's environment is at an optimal temperature and humidity, and that maximal distribution of the spores from the fruiting body that sprouts out of the dead insect is achieved.[4] Marks have been found on fossilised leaves which suggest this ability to modify the host's behaviour evolved more than 48 million years ago.[5]
The genus has a worldwide distribution and most of the approximately 400 species[6] have been described fromAsia (notably Nepal, China, Japan, Korea, Vietnam and Thailand). Cordyceps species are particularly abundant and diverse in humid temperate and tropical forests.
The genus has many anamorphs (asexual states), of which Beauveria (possibly including Beauveria bassiana,Metarhizium, and Isaria) are the better known, since these have been used in biological control of insect pests.
Some Cordyceps species are sources of biochemicals with interesting biological and pharmacologicalproperties,[7] like cordycepin; the anamorph of Cordyceps subsessilis (Tolypocladium inflatum) was the source ofciclosporin—a drug helpful in human organ transplants, as it suppresses the immune system(Immunosuppressive drug).[8]

[edit]Potential pharmacology
The Cordyceps mushrooms have a long history as medicinal fungi. The earliest clear record is a Tibetan medical text authored by Zurkhar Nyamnyi Dorje in the 15th Century outlining the tonic propensities of Yartsa gunbu (Cordyceps sinensis renamed now to Ophiocordyceps sinensis), especially as an aphrodisiac.[9] Although there are often-repeated claims of thousands of years of use in traditional Chinese medicine, so far no clear textual source has surfaced.
Although in vitro and animal models provide preliminary support for some of the traditional medicinal uses, there are no clinical studies demonstrating health benefits in humans.[10] Some polysaccharide components and cordycepin, which have some anticancer activity in preliminary in vitro and animal studies,[11] have been isolated from C. sinensisand C. militaris. Some work has been published in which Cordyceps sinensis has been used to protect the bone marrow and digestive systems of mice from whole body irradiation.[12] An experiment noted a chemical compound isolated from Cordyceps sinensis may protect the liver from damage.[13] An experiment with mice noted that Cordyceps sinensis may have an anti-depressant effect.[14] Researchers have noted that a polysaccharide isolated from Cordyceps sinensis has a hypoglycemic effect and may be beneficial for people with insulin resistance.[15][16][17][18][19]
[edit]Ma Junren case
Ma Junren, the coach of a group of female Chinese athletes who broke five world records in distance running in 1993 at the National Games in Beijing, China, told reporters that the runners were taking Cordyceps at his request.[20] The number of new world records being set at a single track event caused much attention and suspicion of drug use, and the records are still widely regarded as dubious, as the athletes failed to match these performances outside of China at independently drug tested events where illicit substances other than cordyceps would be detected.
[edit]Value
According to Daniel Winkler, the price of Cordyceps sinensis has risen dramatically on the Tibetan Plateau, basically 900% between 1998 and 2008, an annual average of over 20% (900%/10yr = 20%/annum, or maybe, 90%/yr.) However, the value of big-sized caterpillar fungus has increased more dramatically than smaller size Cordyceps, regarded as lower quality.[21]
| Year | % Price increase | Price/kg (Yuan) |
|---|---|---|
| 1980s | 1,800 | |
| 1997 | 467% (incl. inflation) | 8,400 |
| 2004 | 429% (incl. inflation) | 36,000 |
| 2005 | 10,000–60,000 |
According to Modern Marvels, a show on the History Channel, mushroom hunters in Nepal can earn 900 dollars for an ounce of cordyceps.[1]
