The author gives an account of a report of the Nomenclature Committee of the International Society for Human and Animal Mycology making the present terminology of mycoses more precise and unified. Changes recommended by the Committee are designed to eliminate the instability of currently used terms influenced by new names of mycological taxonomy as well as by clinical aspects and the pathology of mycoses. The essential feature of the changes is a recommendation for fungal disease names not based on the word derived from the taxon of the causative fungal genus but providing, in a narrow or broader way, information on the clinical and pathological entity caused by the fungus. The individual recommendations are supplemented by explanatory examples and a list of accepted and rejected fungal disease names is tabulated.
