This paper deals with two yeast cultures of an unique species belonging to the genus Hansenula. They were isolated respectively from soil and fallen decayed leaves in Japan.Judging from many microbiological properties, particularly from the following ones, these isolates agree well with the properties listed for Hansenula beijerinckii Van der Walt.i) Formation of saturn-shaped ascospores.ii) Stable ability of assimilating maltose, in contrast to some of the known species with saturn-shaped ascospore in which assimilation of maltose in entirely lacking or often variable.However, there seems to be a difference in the ascus formation between the original species and our isolates, that is, conjugation of vegetative cells preceding sporulation was not observed in our isolates, which fact suggests that most of all vegetative cells of this species are diploid, as Wicherham pointed out.The two cultures (L.K.B. -0162 and 0163) have been deposited in the Centraal Bureau voor Shimmelcultures (Delft, Holand)
