Abstract The genus Malassezia has been revised using morphology, ultrastructure, physiology and molecular biology. As a result the genus has been enlarged to include seven species comprising the three former taxa M. furfur, M. pachydermatis and M. sympodialis, and four new taxa M. globosa, M. obtusa, M. restricta and M. slooffiae. The descriptions of all the species include morphology of the colonies and of the cells, together with ultrastructural details. The physiological properties studied were the presence of catalase, the tolerance of 37 degrees C and the ability to utilize certain concentrations of Tween 20, 40, 60 and 80 as a source of lipid in a simple medium. Information is given for each of the taxa on mole\% GC and also the rRNA sequence from the comparison previously described for the genus.
