TL;DR: A hitherto undescribed ballistospore-forming yeast was isolated from Knightia excelsa infected by sooty molds collected in New Zealand and is characterized by ubiquinone-9 and the lack of xylose in the cells so that it is included in the genus Bensingtonia.
Abstract: A hitherto undescribed ballistospore-forming yeast was isolated from Knightia excelsa infected by sooty molds collected in New Zealand It is characterized by ubiquinone-9 and the lack of xylose in the cells so that it is included in the genus Bensingtonia This yeast resembles B intermedia and B yamatoana but is easily distinguished from these two species by the assimilation of nitrate and lactose and the requirement of pyridoxine Bensingtonia ingoldii Nakase et Itoh sp nov is proposed for this yeast

TL;DR: A new genus Ballistosporomyces Nakase, Okada et Sugiyama in the Hyphomycetes is described for yeasts that reproduce by both non-ballistOSporous conidia and ballistospores, but not by budding yeast cells.
Abstract: A new genus Ballistosporomyces Nakase, Okada et Sugiyama in the Hyphomycetes is described for yeasts that reproduce by both non-ballistosporous conidia and ballistospores, but not by budding yeast cells. Non-ballistosporous conidia are produced on a sterigma-like stalk which proliferates sympodially or percurrently. Strains in this genus have Q-10 as the major isoprenologue of ubiquinone, do not contain xylose in the cells, and show positive Diazonium blue B reaction. Two new species, Ballistosporomyces xanthus (type species) and B. ruber, are described in the genus. Ballistosporomyces xanthus has a G+C content of DNA of 62.1mol% and forms yellow colonies, whereas B. ruber has a G+C content of DNA of 50.8mol% and forms red colonies. Some properties of the new genus indicate a Ustilaginale affinity. Ontogenetic and chemotaxonomic comparisons are made between Ballistosporomyces and other supposedly related basidiomycetous yeast genera.
