Abstract

Isaria macroscyticola is a hypocrealean pathogen of Cydnidae first described by Dr. Yosio Kobayasi in 1941. Since then, records of this species have been limited, and therefore no cultures have been established and its phylogenetic position is unknown. Recently, synnemata on Macroscytus japonensis were collected from Kanagawa Prefecture, Japan. These were identified as I. macroscyticola based on the morphologies of the synnemata, conidiophores, and conidia. Since cultures established by conidial isolations exhibited pale purplish colonies and Acremonium-like synanamorph, this species was suggested to belong to Purpureocillium (Ophiocordycipitaceae) rather than Isaria (Cordycipitaceae). The sequence similarities of the internal transcribed spacer region and 28S of nuclear ribosomal DNA and the elongation factor 1-alpha gene sequence of I. macroscyticola and P. lilacinum were 99100%. Furthermore, I. macroscyticola was phylogenetically nested within the P. lilacinum clade. Accordingly, we conclude that I. macroscyticola is a synnematous form and synonym of P. lilacinum.
