Abstract:
Cletus P. Kurtzman transformed the way yeast systematists practice their trade and how they perceive the yeast species. He redefined many genera of ascomycetous yeasts and provided a sound basis upon which to base higher taxonomic categories. Within his extraordinary corpus lies a trail of elements that can be used to reconstruct his evolving vision of the concepts that underlie the species and the genus, rarely set in a theoretical framework. While occasionally tipping his hat to the biological and phylogenetic species, Kurtzman espoused a concept founded primarily on genetic distance, even when claiming otherwise. In contrast, his notion of genus incorporated components of both genetic distance and phylogenetic structure, and possibly a size consideration. A phylogenetic approach predominated with higher taxa.
