The relationships between strains of the genera Cryptococcus, Filobasidiella, Filobasidium, and related microorganisms were studied comparing enzymes electrophoretically. In the genus Cryptococcus, seven species out of eleven and five varieties out of six had considerable variations in their enzymatic patterns. They were: Cryptococcus albidus var. albidus, C. albidus var. diffluens, C. hungaricus, C. luteolus, C. skinneri, C. laurentii var. laurentii, C. laurentii var. flavescens, C. laurentii var. magnus, C. macerans, and C. ater. Certain strains of C. albidus var. albidus and C. kuetzingii produced identical enzymatic patterns. The different serotypes of the two species of Filobasidiella were distinguishable by their enzymatic patterns. Leucosporidium scottii strains were considered to comprise at least two species. C. flavus and Rhodotorula rubra produced similar enzymatic patterns. Moreover, C. macerans and one strain of Rhodotorula glutinis showed similar enzymatic patterns.
