Some wood-inhabiting yeasts of trembling aspen (Populus tremuloides) from Alberta and northeastern British Columbia

Abstract

In a survey of wood-inhabiting fungi of trembling aspen, nine species of yeast fungi were recovered from wood of 19 individual trees from four localities in western Canada. Identification of the isolates revealed that Pichia minuta var. minuta, a species apparently restricted to Populus, in addition to Candida ernobii and Cryptococcus skinneri were the taxa most frequently encountered. This report extends the known substrate and geographic range for most of the species found.
