Phylogeny and taxonomy of two new Plectosphaerella (Plectosphaerellaceae, Glomerellales) species from China

Abstract

The genus <i>Plectosphaerella</i> is the largest genus in the family Plectosphaerellaceae. Some species are plant pathogens, whereas others are soil-borne. Seven <i>Plectosphaerella</i> isolates were collected from various locations in the southwest of China. Using multi-locus phylogenetic (LSU, ITS, EF1α, RPB2) analyses combined with morphological characteristics, two new species, <i>Plectosphaerella guizhouensis</i> <b>sp. nov.</b> and <i>Plectosphaerella nauculaspora</i> <b>sp. nov.</b> are described, illustrated and compared with related species.
