BULLERA INTERMEDIA SP. NOV. AND SPOROBOLOMYCES ORYZICOLA SP. NOV. ISOLATED FROM DEAD LEAVES OF ORYZA SATIVA

Abstract

Two new species of ballistospore-forming yeasts isolated from dead leaves of Oryza sativa L. are described as Bullera intermedia Nakase et Suzuki and Sporobolomyces oryzicola Nakase et Suzuki. Unlike the other species of Bullera, Bullera intermedia has Q-9 as its major ubiquinone component. Sporobolomyces oryzicola produces deeply pigmented colonies similar to those of typical species of the genus Sporobolomyces, whereas it forms rotationally symmetrical ballistospores and assimilates 2-keto- and 5-ketogluconic acid.
