Reassessment of type specimens of Cordyceps and its allies described by Dr. Yosio Kobayasi, preserved in the National Museum of Nature and Science. Part 2: Cordyceps (Elaphocordyceps) on Elaphomyces

Four holotype specimens of Cordyceps parasitic on Elaphomyces that were originally described by Dr. Yosio Kobayasi and Mr. Daisuke Shimizu were relocated, and TNS (National Museum of Nature and Science, Japan) registration numbers (TNS-F-number) were assigned: viz. Cordyceps minazukiensis (TNS-F-197989), C. ophioglossoides var. cuboides (TNS-F-230312), C. valvatistipitata (TNS-F-230284), and Cordyceps x jezoensoides (TNS-F-230286). Two specimens were selected as lectotypes: C. delicatistipitata (TNS-F-230293) and C. ophioglossoides f. alba (TNS-F-18223). Those taxa, except for Cordyceps x jezoensoides, have been treated as members of the genus Elaphocordyceps in the latest taxonomy. The new combination Elaphocordyceps x jezoA << nsoides (Kobayasi) is proposed. In addition, Elaphomyces asahimontanus Kobayasi, the host of Cordyceps delicatistipitata, is lectotypified (TNS-F-230293).
