Abstract

Two groups of fungi which include organisms pathogenic for humans have received some attention from medical men in recent years. These groups, the true yeasts and the false yeasts, have been studied only superficially from a standpoint of morphology and taxonomic relationships; hence, the classification and nomenclature, particularly of the false yeasts, has been in a state of confusion. The true yeasts, those which produce ascospores and form no mycelium, are placed in the family Saccharomycetaceae, order Endomycetales, class Ascomycetes. The yeast-like organisms for which no perfect stage has been demonstrated are grouped in one form family (given various names by different authors) of the Fungi Imperfecti. The majority of these false yeasts were originally placed in this group, and further taxonomic work has not been reported. Many of them are human pathogens, such as the organisms causing "Torula" or "yeast" meningitis, and those causing pulmonary or other infections. Benham (1) uses the form family Pseudo-saccharomycetaceae, order Moniliales, to include these forms.
