sp. nov. Isolated from subsp. in Korea.

A new species belonging to the genus was isolated from the necrotic leaf spots of subsp. in Yuseong district, Daejeon, Korea. It is an occasional isolate, not an etiological agent, which is morphologically similar to , but differs in conidial size and conidiophore shape. Phylogenetic analysis using the sequence datasets of the internal transcribed spacer (ITS) region of the rDNA, glyceraldehyde-3-phosphate dehydrogenase (gpd), and plasma membrane ATPase genes showed that it is distantly related to and closely related to species in the section , which belonged to a clade basal to the section . Morphologically, the species is unique because it produces solitary conidia or conidial chains (two units), unlike the four members in the section that produce conidia as short branched chains. It exhibits weak pathogenicity in the host plant. This report includes the description and illustration of as a new species.
