Torulopsis geochares and Torulopsis azyma, two new, haploid species of ascomycetous affinity.

There strains representative of two undescribed Torulopsis species, T. geochares and T. azyma, were recovered from soil and rupicolous lichen in South Africa. Descriptions of the new species are given. Ploidy determinations by X-ray inactivation showed the type strains of the two new species to be haploid. On the basis of their affinitive characteristics the new species appear to be related to the ascomycetous yeasts.
