Curvularia tsudae comb. nov. et nom. nov., formerly Pseudocochliobolus australiensis, and a revised synonymy for Curvularia australiensis

Cultures originally identified as Drechslera australiensis, from seeds of Chloris gayana in Japan, were the basis for Tsuda and Ueyama's new combination, Bipolaris australiensis, and its associated sexual morph Pseudocochliobolus australiensis. By studying ex-type materials of both Drechslera australiensis, which was originally isolated from seeds of Oryza sativa in Australia, and Pseudocochliobolus australiensis, we show by morphological and molecular phylogenetic analysis that these two specimens represent different species. Taxonomic confusion is resolved by the transfer of Pseudocochliobolus australiensis to Curvularia tsudae comb. nov. et nom. nov., together with a revised synonymy for Curvularia australiensis. © 2014 The Mycological Society of Japan.
