This paper deals with a yeast culture isolated from soil in Brasil. Because of its unique spore morphology (warty wall of the spore), it must doubtlessly be classified as genus Debaryomyces. Among the species of Debaryomyces hitherto reported, no species is known which has biochemical characteristics for both fermentation of sugars and assimilation of carbon compounds corresponding to those of isolate. Further, if the spore morphology is not taken into consideration from the view point of taxonomy, the isolate resembles Torulaspora nilssoni Capriotti in many properties. Particularly, our comporative studies of our isolate with a type culture of T. nilssoni (C. B. S.-2924) revealed that the former sgrees quite well with the latter in the characteristics mentioned abode. In additon, a distinctly warty wall was observed in the spores of the type culture of the latter under the electron microscope as shown in Fig. V. and VI. Therefore, it is of the author's opinion that Torulaspora nilssoni should be transferred to the species of Debaryomyces. Eventually, the authors concluded that the isolate under discusion should be identified as Torualspora nilssoni Capriotti the name of which they wish to change to Debaryomyces nilssoni (Capriotti) nov. comb., based predominantly on the remarkable characteristic of spore morphology mentioned above. A type culture of the isolate (L. K. B. D-637) has been desposited in the Yeast Collection of the Centraalbureau voor Schimmelcultures (Delft, Holland). Judging from the existence of yeasts which form ascospore with a warty wall (distinctly observed under the electron microscope) and at the same time possess rather strongly fermengtative power, it seems reasonable to broaden the definition of genus Debaryomyces so that the genus may include various species ranging from entirely oxidative species to strongly fermentative ones, attaching basic importance to the spore morphology teh authors have reaffirmed.
