Abstract
Two strains of ballistocondium-forming yeasts, isolated from plants collected in the south-east seacoast of Bangkok, Thailand, were described. The strains (K-272(T) and K-337(T)) were assigned to the genera Bullera and Kockovaella, respectively, based on morphological and chemotaxonomical characteristics. Phylogenetically, strain K-272(T) is close to Bullera hannae, and strain K-337(T) is close to Kockovaella thailandica and Kockovaella imperatae. These two strains represent new species based on DNA-DNA reassociation experiments. Bullera penniseticola Takashima et Nakase sp. nov. and Kockovaella sacchari Takashima et Nakase sp. nov. are proposed for K-272(T) (=JCM 9857(T)) and K-337(T) (=JCM 9858(T)), respectively.
