Morphology and physiology of a strain of <i>Bullera alba</i> was studied. The fungus could be distinguished from <i>Cryptococcus laurentii</i> var. <i>flavescens</i> only on the base of ballistospore formation. The isolate studied formed a true septate mycelium.

Morphology and physiology of strains of <i>Cryptococcus laurentii</i> var. <i>magnus</i> and <i>C. albidus</i> var. <i>albidus</i> isolated from winter wheat seeds was studied. It was concluded on the basis of morphological similarity that these fungi were closely related. Resting spores of a "dangeardien'' type were found in <i>C. laurentii</i>, while in some cultures of <i>C. albidus</i> unusually large resting spores were dis00vered.

Morphology and physiology of strains of <i>Crvptococcus laurentii<i> var. <i>laurentii</i> and var. <i>flavescens</i> was studied. Morphological features found in var. <i>laurentii</i> suggested a close relation to <i>Sporobolomycetaceae</i>, and in particular to <i>Bullera alba</i> (Hanna) Derx.

Morphology and physiology of strains of <i>Sporobolomvces roseus</i> and <i>S. pararoseus</i> isolated from winter wheat seeds was studied. Most of strains <i>S. roseus</i> and all strains of <i>S. pararoseus</i> exhibited a positive starch reaction, and showed a tendency to lose the ability of formation of ballistospores. In some strains of <i>S. pararoseus</i> adaptation to nilratc nitrogen occurred.

Morphology and physiology of strains of <i>Candida albicans</i> and <i>C. tropcalis</i> isolated from winter wheat seeds were studied. Three groups of strains of <i>C. albicans</i> were differentiated. Strains of <i>C. tropicalis</i> differed in some morphologlcal and physiological details from a standard description of the species.
