Abstract
This review, which is necessary for the development of new simplified identification keys, presents the morphological, cultural, and physiological characteristics of over 100 new species of yeasts described since the publication of The yeasts, a taxonomic study (J. Lodder (Editor). 1970. North-Holland Publishing Company, Amsterdam) and A new key to the yeasts (J. A. Barnett and R. J. Pankhurst (Editors). 1974. North-Holland Publishing Company, Amsterdam). All the descriptions in this work come from the authors who first described the species. Information on the synonymy of the new species was gathered on both the perfect state and the imperfect state of the yeasts and yeastlike fungi.
