Abstract
One hundred and one strains of ballistospore-forming yeasts isolated from 48 samples of dead leaves of a weed, Miscanthus sinensis, were identified as 16 species in the genera Bullera, Sporobolomyces, and Tilletiopsis: Forty-six of 51 strains of Bullera were assigned to B. megalospora (18 strains), B. crocea (15 strains), B. alba (3 strains), B. piricola (3 strains), B. oryzae (3 strains), B. pseudoalba (3 strains), and B. derxii (1 strain). Five strains resembled unidentified yeasts isolated from the dead leaves of Oryza sativa. Forty-one of 47 strains of Sporobolomyces were assigned to Sp. roseus (37 strains), Sp. salmonicolor (2 strains), and Sp. shibatanus (2 strains). Four strains represented 3 new species and were described as Sp. miscanthi (2 strains), Sp. subroseus (1 strain), and Sp. wejimanii (1 strain). These new species had Q-9 as the major ubiquinone. The remaining 2 strains of Sporobolomyces represent a single species, still unidentified. Three strains of Tilletiopsis were assigned to T. lilacina. The frequency of isolation of each species from Miscanthus sinensis is compared with that from Oryza sativa.
