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 saliva. 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.
weijmanii (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.
