Several yeast strains were isolated from leaves collected from Mt. Daedun and Mt. Chilgap in Korea. A total of 79 strains of 32 species were isolated from 44 leaves obtained from Mt. Daedun. spp., including , were found to be dominant, while 16 strains of pullulans were isolated. Among the strains isolated from Mt. Daedun, JSL502, JSL503, JSL501, Bulleromyces albus JSL505, and JSL507 are considered rare yeast species in Korea. All of these rare strains, except for Bulleromyces albus JSL505, formed ascospores. JSL501 was able to grow in yeast extract-peptone-dextrose (YPD) medium containing 10% NaCl. Twenty-five yeast strains of 18 species were isolated from 43 leaves obtained from Mt. Chilgap. Six strains of spp., including three strains of , were isolated in the dormant state. Of these strains, the occurrence of JSL515, JSL516, JSL517, and JSL518 is rare in Korea. Only JSL518 formed ascospores, while JSL516 and JSL518 formed pseudomycelia. The halophilic yeast JSL517 was isolated and observed to grow in YPD medium containing 5% NaCl.
