Abstract
A Cordyceps species was found with a Beauveria anamorph state on larval insect cadavers on Obong mountains in Gangwon Provinces, Republic of Korea. Cultures from discharged aseospores formed an anamorph identifiable as Beauveria bassiana. This teleomorph-anamorph connection was also confirmed by the in vitro production of fertile aseomata from conidial cultures with morphology like that of lield-eolleeted specimen. This is the first report of in vitro production of a teleomorph for any Beauveria species. The Cordyceps species has been eonspeeilied as Cordyceps bassiana, a species described from China with B. bassiana anamorph.
