Neotypification of Claviceps humidiphila and recognition of C. bavariensis sp. nov.

Abstract

Claviceps humidiphila [≡ C. purpurea var. phalaridis] was previously typified with the holotype collected by Tanda in Japan and an epitype from Bavaria, Germany. Phylogenetic analyses based on translation elongation factor 1-α (TEF1-α) and RNA polymerase II second largest subunit (RPB2) indicated that the previously designated epitype from Germany was not conspecific with the Japanese species. The German specimen is proposed as a new species, C. bavariensis, and a specimen collected from the type location (Chiba, Japan) is designated as a neotype for C. humidiphila, replacing the lost holotype.
