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.
