Four new species of the genus Sporobolomyces isolated from leaves in Thailand

Thirteen undescribed strains of ballistoconidium-forming yeasts, isolated from leaves collected in the suburbs and along the southeast seacoast of Bangkok, Thailand, were divided into four different groups in the genus Sporobolomyces on the basis of morphological, physiological, biochemical, and chemotaxonomical characteristics, and analyses of the sequences of 18S rDNA and internal transcribed spacer regions. DNA-DNA reassociation experiments with related species revealed that these four groups were four new distinct species. Sporobolomyces nylandiisp, nov., S. poonsookiae sp. nov., S. blumeae sp. nov. and S. vermiculatus sp. nov. are proposed for these strains.
