The entomogenous anamorphic fungus lsaria takamizusanensis has not been resolved clearly in its teleomorphic state. We succeeded in inducing ascostroma formation by incubating conidiomata of I takamizusanensis on cicada adults in a moist chamber. We observed the ascostroma and conducted a phylogenetic analysis based on ITS rDNA and EF-l alpha genes. The morphology of the ascostroma was identical to that of Cordyceps ryogamimontana. In the phylogenetic tree inferred from EF-la, the isolate from the partspores grouped with nine strains derived from conidia of I. takamizusanensis, which was distinct from a clade including Purpureocillium lilacinum. Moreover, a conidial structure identical to that of I. takamizusanensis was rediscovered on the holotype specimen of C. ryogamimontana. As a result, we propose a new name, Purpureocillium takamizusanense, which is a combination of the teleomorph-anamorph connection of C. ryogamimontana-I. takamizusanensis, in accordance with the 'one fungus, one name' concept of the International Code of Nomenclature for Algae, Fungi, and Plants (ICN).
