Heterosporicola beijingense sp. nov. associated with Chenopodium quinoa leaf spots

A coelomycetous fungus with hyaline, aseptate, oblong to ellipsoidal conidia was isolated from living Chenopodium quinoa leaves with leaf spots, in Beijing, China. Maximum likelihood and Bayesian analyses of a combined LSU, SSU, ITS and TEF sequence dataset confirmed its placement in Heterosporicola...

Description
Summary:A coelomycetous fungus with hyaline, aseptate, oblong to ellipsoidal conidia was isolated from living Chenopodium quinoa leaves with leaf spots, in Beijing, China. Maximum likelihood and Bayesian analyses of a combined LSU, SSU, ITS and TEF sequence dataset confirmed its placement in Heterosporicola in Leptosphaeriaceae. The new taxon resembles other Heterosporicola species, but is phylogenetically distinct, and is introduced as a new species. Heterosporicola beijingense sp. nov. is compared with other Heterosporicola species, and comprehensive descriptions and micrographs are provided. Key words. DNA analyses, morpho-molecular taxonomy, pathogens.
