A new Neotyphodium species from Festuca parvigluma Steud. grown in China

     Department of Microbiology, College of Life Sciences, Nanjing Agricultural University, Nanjing 210095, China

Neotyphodium species evolved from Epichloë species and are asexual, seedborne endophytes in many cool-season grasses. Here we propose a new species inhabiting Festuca parvigluma native to China. Morphology, host specificity and molecular phylogenetic evidence supported recognition of this new species. Sequences of β-tubulin gene (tubB) introns and translation elongation factor 1- gene (tefA) introns were present as two copies in all five isolates examined. In phylogenetic analyses copy 1 was closely related to E. yangzii in the EBY clade and copy 2 with E. typhina in the ETC clade, indicating this new species might have originated as a result of hybridization between members of these two clades. Referring to the distribution area of host plants, Neotyphodium sinofestucae is proposed for this new species.
