A new species and two new Chinese records of Ochroconis from sugarcane and banana rhizosphere in Guangxi, China

Ochroconis guangxiensis isolated from sugarcane and banana rhizosphere, was described as a new species based on morphological characteristics and phylogenetic analysis using sequence data of the nuclear small subunit rRNA gene (SSU), internal transcribed spacer (ITS) region and large subunit (LSU) rRNA gene. Taxonomic and phylogenetic remarks are also provided for O. minima and O. ramosa. The latter two species are newly recorded for China. These three Ochroconis species, as dark septate endophytes, inhabit rhizosphere and can form a symbiosis with sugarcane and banana.
