“…Since then, it has attracted attention of great mycologists such as Persoon (1799), Fries (1823), Link (1833), Berkeley (1843), Tulasne Brothers (1865), Saccardo (1883) and Massee (1895) and was described under different generic names. Old literature proposed different generic names for Cordyceps such as Clavaria , Sphaeria and Torrubia , before Link (1833) finally erected Cordyceps as a new generic name. During last hundred years or more, regional exploration of Cordyceps species continued in many parts of the world such as Australia (Olliff, 1895; Willis, 1959), North America (Seaver, 1911; Mains, 1958), New Zealand (Dingley, 1953), Ceylon (present day Sri Lanka) (Petch, 1924), Great Britain (Petch, 1932, 1948), Japan (Kobayasi, 1939a, b, 1941; Kobayasi and Shimizu, 1983), Congo (Moureau, 1962), Norway (Eckblad, 1967), Ghana (Samson et al, 1982), Taiwan (Tzean et al, 1997), Amazonia (Evans and Samson, 1982, 1984; Samson and Evans, 1985), Thailand (Hywel-Jones 1994, 1995a, b, c, 1996; Hywel-Jones and Sivichai, 1995), Korea (Sung, 1996), China (Zang and Kinjo, 1998), and Mexico (Guzman et al, 2001).…”
