Sporobolomyces koalae is a species of fungus in the order Sporidiobolales. It is an anamorphic yeast. Strains of the yeast were isolated from nasal swabs from three of five captive Queensland koalas (Phascolarctos cinereus) kept at the Kobe Oji Zoo in Kobe, Japan. Swabs from three zoo keepers were examined as well, but tested negative for the presence of the yeast. It is not suspected to be pathogenic, as the koalas from which it was isolated were healthy.
