Recent molecular phylogenetic studies show that the genus "Candida", as currently defined, is extremely polyphyletic (encompassing distantly-related species that do not form a natural group). Before the advent of inexpensive molecular methods, yeasts that were isolated from infected patients were often called "Candida" without clear evidence of relationship to other "Candida" species. For example, "Candida glabrata", "Candida guilliermondii", and "Candida lusitaniae" are clearly misclassified and will be placed in other genera once phylogenetic reorganization is complete (for example, see Khunnamwong "et al." 2015).
