SPOROBOLOMYCES GRISEOFLAVUS AND SPORO- BOLOMYCES SASICOLA, TWO NEW SPECIES OF BALLISTOSPOROUS YEASTS ISOLATED FROM DEAD LEAVES OF SASA SP. IN JAPAN

Abstract

Two new species of ballistospore-forming yeasts, Sporobolomyces griseoflavus and Sporobolomyces sasicola, were isolated from dead leaves of Sasa sp. collected on a mountain in Japan. They form pale colored colonies and bilaterally symmetrical ballistospores, have Q-10 as the major ubiquinone and do not contain xylose in the cells. The taxonomic relationship of these new yeasts to Sporobolomyces singularis are discussed.
