Intraspecific diversity among yeasts, including basidiomycetous yeasts has mostly been studied from a taxonomic point of view. The heterobasidiomycetous genus Cryptococcus is no exception and it was found to contain species that display heterogeneity both on a genetic and physiological level, i.e. diversity among strains originating from different geographical areas. It was stated that this diversity within yeast species is possibly caused by intrinsic attributes of the different habitats the strains of a particular species originate from. However, little is known about the diversity of a species within a specific habitat. Thus, in this study intraspecific diversity among selected cryptoccoci isolated from a single soil sample originating from pristine Fynbos vegetation , was investigated.
