Abstract

Thirty-two cultures of spore-discharging false yeasts were isolated from the air and from other sources examined. Detailed studies identified twenty-six of the cultures as members of the genus Sporobolomyces and the remaining six as members of the genus Bullera. Twelve of the cultures of Sporobolomyces were classified as S. salmonicolor, eleven as S. roseus and the remaining three cultures apparently constitute a new species. The six cultures of Bullera were all identified as B. alba. Considerable variation was noted among the cultures of each species of Sporobolomyces and Bullera but, since marked variations in a culture could be induced by varying the growth conditions, the differences did not seem significant enough to warrant classification of variant cultures as separate species. Evidence obtained suggests that the species S. roseus and S. tenuis reported by Kluyver and van Neil be classified as one species, S. roseus.
