Abstract

Typhula ishikariensis and the related fungi were separated into three biological species by morphological and physiological characteristics, as well as DNA sequences and mating reactions. We propose that the T. ishikariensis complex should be divided into three species (T. ishikariensis, T. canadensis and T. hyperborea) and two varieties (T. ishikariensis var. ishikariensis and var. idahoensis). Typhula hyperborea was reappraised to be recognized also as a separate species of the T. ishikariensis complex.
