Nine strains of ballistospore-forming yeasts were isolated from dead leaves of various kinds of plants in Japan and were found to comprise a single, hitherto undescribed species of the genus Sporobolomyces. The species is described here as Sporobolomyces yamatoanus Nakase, Suzuki et Itoh. Sporobolomyces yamatoanus produces large, sickle-shaped to kidneyshaped ballistospores, produces pale colored colonies, has Q-9 as the major isoprenologue of the ubiquinones, and does not contain xylose in the cells. These characteristics coincide well with those of species placed in the intermedius group, a group of atypical species in the genus Sporobolomyces. This is the seventh species in the intermedius group.During a survey on ballistospore-forming yeasts living on the surface of Miscanthus sinensis, two strains of hitherto undescribed yeasts having Q-9 as the major ubiquinone were isolated (1). They seemed to comprise a single species. We did not describe this yeast as a new species but merely reported it as Sporobolomyces sp. because three additional strains, supposedly belonging to the same species, were obtained from dead leaves of Sasa sp. collected in a mountainous area of central Japan. Comparative studies of these strains were required before we could describe them as a new species (1). Later we isolated four additional strains of this undescribed yeast from plant materials collected at Mt. Fuji. These nine strains represent a single species. They are described here as the new species Sporobolomyces yamatoanus Nakase, Suzuki et Itoh.

“…These characteristics coincide well with species of the intermedius group in the genus Sporobolomyces (1,9). Sporobolomyces yamatoanus is the seventh species of this group.…”

“…This is rarely found in ascomycetous yeasts but sometimes appears in basidiomycetous yeasts (3), especially in ballistospore-forming genera Sporobolomyces and Bensingtonia (27,28,(31)(32)(33)35).…”

“…But the positive Diazonium blue B reaction of this strain suggests its basidiomycetous nature. This strain could not grow above 23°C and is considered to be a psychrophile, as is often found in basidiomycetous yeasts including ballistospore-forming genera Bensingtonia, Bullera and Sporobolomyces (3,29,33,34,36,40).…”

A new genus Ballistosporomyces Nakase, Okada et Sugiyama in the Hyphomycetes is described for yeasts that reproduce by both nonballistosporous 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. ruher, are described in the genus. Ballistosporomyces xanthus has a G + C content of DNA of 62.1 mol% and forms yellow colonies, whereas B, ruher has a G + C content of DNA of 50.8 mol% 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.In 1987, Nakase (26) reported the isolation of two strains of yeasts which produce both ballistospores and "sterigmatoconidia" (conidia developed on sterigmata, not forcibly discharged, and often observed in strains of Sterigmatomyces and Fellomyces), but not budding cells. These two yeasts represent two distinct species but they cannot be placed in any known genera. Therefore, a new anamorphic yeast genus, Ballistosporomyces Nakase, Okada et Sugiyama, in the Hyphomycetes, is proposed for these yeasts. Two new species, Ballistosporomyces xanthus Nakase, Okada et Sugiyama (type species) and B, ruher Nakase, Okada et Sugiyama are described in the genus.

Sporobolomyces yuccicola, a new species of ballistosporous yeast equipped with ubiquinone-9

A hitherto undescribed ballistosporous yeast was isolated from a dead leaf of Yucca sp. in Canada. This yeast produces apiculate or short-ellipsoidal ballistospores, produces pale colored colonies, has Q-9 as the major ubiquinone, and does not contain xylose in the cells. This new yeast is described as Sporobolomyces yuccicola Nakase et Suzuki. Sporobolomyces yuccicola is the sixth species of the intermedius group, a group of atypical species of the genus Sporobolomyces equipped with Q-9.
