Publisher Summary This chapter focuses on Malassezia genus and its member species. Asexual reproduction in this genus occurs typically through monopolar (phialidic) enteroblastic budding on a broad base. Elongate hyphal-like cells are rare in culture but true hyphae with clusters of blastospores may be commonly observed in skin scales from hosts. The formation and separation of the bud generally leaves a pronounced scar or collar from which later buds emerge. The cell walls of this genus are multilamellar in nature, and the inner layer of the cell wall as observed with electron microscopy is corrugated with the grooves spiraling from the bud site. The member species of this species are Malassezia furfur, Malassezia pachydermatis, and Malassezia sympodialis. The cells of Malassezia furfur, after growth on glucose-peptone-yeast extract agar with olive oil for three days at 34° C, appear as ovoidal to ellipsoidal. The cells of Malassezia pachydermatis, after undergoing growth on glucose-peptone-yeast extract agar for three days at 34° C, appear mostly as ellipsoidal.
