Cordyceps sensu lato contains more than 400 entomopathogenic and mycoparasitic species. It was traditionally classified in Clavicipitaceae of Hypocreales and recently phylogenetically separated into several genera such as Cordyceps Fr. 1818 emend. G. H. Sung et al.(Cordycipitaceae Kreisel ex Sung et al.), Elaphocordyceps G. H. Sung & Spatafora and Ophiocordyceps Petch emend. G. H. Sung et al.(Ophiocordycipitaceae G. H. Sung et al.), and Metacordyceps G. H. Sung et al . and Tyrannicordyceps Kepler & Spatafora (Clavicipitaceae (Lindau) Earle ex Rogerson). Some species of Cordyceps sensu lato (e.g., C. militaris and C. pruinosa) are highly regarded as medicinal mushrooms in East Asia. Beauveria species, on the other hand, are widely used as potential biocontrol agents for insects in agriculture and forest due to their wide host range and global distribution. A recently described Beauveria species, Beauveria sungii S.A. Rehner & Humber 2011, is here shown as the anamorph of Cordyceps scarabaeicola Y. Kobayasi 1976 based on the teleomorphic material and phylogenetic analysis of the B.sungii isolate KACC 47482. In Cordyceps sensu stricto clade, Cordyceps Fr. 1818 is an older generic name than Beauveria Vuill. 1912 .Hence ,C. scarabaeicola is suggested to be adopted for B. sungii on the priority basis of both generic name and species epithet in view of the recent revision of Article 59 of the Melbourne Code (recently changed to the ‘International Code of Nomenclature for algae, fungi, and plant’orICN). Based on one fungus = one name principle, all legitimate Beauveria species are also proposed to be transferred to Cordyceps. The consequences of abandonment of dual nomenclature for pleomorphic fungi are also briefly discussed with reference to Cordyceps and Beauveria.
