Abstract

The phylogenetic relationships among taxa in the Magnaporthaceae are investigated based on DNA sequences of multiple genes including SSU, ITS, LSU, MCM7, RPB1 and TEF1. The genera Magnaporthe and Gaeumannomyces are shown to be polyphyletic and their members are divided into four major groups based on the phylogenetic analyses. Considering morphological, biological and molecular data, we establish a new genus, Magnaporthiopsis. It is characterized by black and globose perithecia with a cylindrical neck, two-layered perithecial wall, clavate asci with a refractive apical ring, fusiform to fusoid and septate ascospores, simple hyphopodia, and Harpophora-like anamorph. Species in this genus are all necrotrophic parasites infecting root of grasses. Three new combinations, Magnaporthiopsis poae, M. rhizophila, and M. incrustans, are proposed accordingly. Potential impacts by the new nomenclature (Melbourne code) on the name of the rice blast fungus are discussed.
