Medicinal Shiitake Mushroom Extract,Edible Shiitake Mushroom Extract
The Shiitake (/ʃɪˈtɑːkeɪ, ˌʃiːɪ-, -ki/; Japanese: [ɕiːtake] Lentinula edodes) is an edible mushroom native to East Asia, which is cultivated and consumed in many Asian countries. It is considered a medicinal mushroom in some forms of traditional medicine.
Taxonomy and naming
The fungus was first described scientifically as Agaricus edodes by Miles Joseph Berkeley in 1877. It was placed in the genus Lentinula by David Pegler in 1976. The fungus has acquired an extensivesynonymy in its taxonomic history:
Agaricus edodes Berk. (1878)
Armillaria edodes (Berk.) Sacc. (1887)
Mastoleucomyces edodes (Berk.) Kuntze (1891)
Cortinellus edodes (Berk.) S.Ito & S.Imai (1938)
Lentinus edodes (Berk.) Singer (1941)
Collybia shiitake J.Schröt. (1886)
Lepiota shiitake (J.Schröt.) Nobuj. Tanaka (1889)
Cortinellus shiitake (J.Schröt.) Henn. (1899)
Tricholoma shiitake (J.Schröt.) Lloyd (1918)
Lentinus shiitake (J.Schröt.) Singer (1936)
Lentinus tonkinensis Pat. (1890)
Lentinus mellianus Lohwag (1918)
The mushroom's Japanese name shiitake (椎茸) is composed of shii (椎 shī, Castanopsis), for the tree Castanopsis cuspidata that provides the dead logs on which it is typically cultivated, and take(茸, "mushroom")] The specific epithet edodes is the Latin word for "edible".
It is also commonly called "sawtooth oak mushroom", "black forest mushroom", "black mushroom", "golden oak mushroom", or "oakwood mushroom".
Habitat and distribution
Shiitake grow in groups on the decaying wood of deciduous trees, particularly shii, chestnut, oak, maple, beech, sweetgum, poplar, hornbeam, ironwood, mulberry, and chinquapin (Castanopsis spp.). Its natural distribution includes warm and moist climates in southeast Asia.
The earliest written record of shiitake cultivation is seen in the Records of Longquan County (龍泉縣志) compiled by He Zhan (何澹) in 1209 during the Southern Song dynasty. The 185-word description of shiitake cultivation from that literature was later crossed-referenced many times and eventually adapted in a book by a Japanese horticulturist Satō Chūryō (佐藤中陵) in 1796, the first book on shiitake cultivation in Japan.
The Japanese cultivated the mushroom by cutting shii trees with axes and placing the logs by trees that were already growing shiitake or contained shiitake spores. Before 1982, the Japan Islands' variety of these mushrooms could only be grown in traditional locations using ancient methods. A 1982 report on the budding and growth of the Japanese variety revealed opportunities for commercial cultivation in the United States.
