Reassessment of type specimens of Cordyceps and its allies, described by Dr. Yosio Kobayasi and preserved in the mycological herbarium of the National Museum of Nature and Science. Part 4. Cordyceps s. l. on Lepidoptera

Dr. Kobayasi and Mr. Shimizu described 31 species of Cordyceps infecting Lepidoptera. Holotype specimens of 14 species and two authentic specimens of one of the 31 species were rediscovered from a herbarium of the National Museum of Nature and Science (TNS). Registration numbers (TNS-F-number) were given to these 16 specimens, and one was lectotypified as follows. Holotypes: Metarhizium indigoticum TNS-F-230337; Yosiokobayasia kusanagiensis TNS-F-197994 (Clavicipitaceae); Beauveria hepialidicola (Kobayasi & Shimizu) Hirok. Sato, S. Ban & Hosoya, comb. nov. TNS-F-197986; Cordyceps ampullacea TNS-F-197981, Cordyceps militaris f. alba TNS-F-230340, Cordyceps ochraceostromata TNS-F-195471, and Cordyceps rosea TNS-F-197972 (Cordyceps sensu stricto, Cordycipitaceae); Ophiocordyceps aurantia TNS-F-195485, Ophiocordyceps cochlidiicola TNS-F-195470, and Ophiocordyceps hiugensis TNS-F-197978 (Ophiocordy-cipitaceae); and Cordyceps changpaishanensis TNS-F-195501, Cordyceps ootakiensis TNS-F-197976, Cordyceps shimizui TNS-F-197995, and Cordyceps sulfurea TNS-F-197974 (Cordyceps sensu lato). Lectotype: Cordyceps bulolensis TNS-F-230327 (Cordyceps sensu lato). A new combination Beauveria hepialidicola comb. nov., is proposed for Cordyceps hepialidicola based on morphological observations.
