This paper deals with 5 yeast cultures isolated from soils sent from abroad, which should be classified in the genus Debaryomyces Klocker judging from their ascospores with distinct warty surface walls formed after hetro or isogamic conjugation. These isolates are similiar to Debaryomyces globosus Klocker in many of their properties, as follows : 1. Fermentation of glucose, saccharose and raffinose2. Assimilation of glucose, saccharose3. No pellicle formation on malt or "koji" extract4. A rather higher maximum temperature for the growth (ie 40-41℃).Whereas, in 1952,Lodder et van Rij changed Debaryomyces globosus to Saccharomyces rosei (Guilliermond) Lodder et van Rji, based predominantly on its strongly fermentative activity. In the author's opinion, however, it seems to be noteworthy that, as in most species belonging to genus Debaryomyces Klocker hitherto reported (except for a very few species such as D. vini etc.) a distinct warty wall of ascospores can be clearly observed in all strains under discussion and therefore this characteristic of ascospores should be considered as one of the most important properties to define the genus Debaryomyces as Klocker originally proposed.Eventually, taking the above mentioned into consideration, the authors wish to identify our isolates not as Saccharomyces rosei but as Debaryomyces globosus which should be regarded as a species of different genus from the former in the morphology of ascospores. A type culture of the isolates (D-1) has been deposited in Centraalbureau voor Schimmelcultures (Delft. Holland).
