Yeast systematics is in transition from reliance on phenotypic characters to application of molecular comparisons. Measurements of molecular divergence represent a quantitative means for assessing genetic relationships among species, and these molecular comparisons have revealed that the standard phenotypic tests used in yeast taxonomy are often poor indicators of relatedness. The impact of molecular comparisons on yeast systematics is discussed and examples of application of these data for rapid species identification are given.
