Abstract

This chapter discusses the genus Cystobasidium. It provides a systematic discussion of the species and concludes with comments on the genus. The diagnosis of the genus is done on the basis of asexual, sexual, physiology and biochemistry, and phylogenetic placement. In asexual reproduction yeast cells are ovoid or elongate and budding is predominantly polar. Ballistoconidia are not formed. Visible carotenoid pigments are formed, and the cultures are pink to orange in color. In sexual reproduction the species is mycoparasitic, and the sexual state develops only when the fungal host is present. Hyphae with clamp connections and haustoria occur. Auricularioid, i.e., transversely septate basidia develop from a swollen, thin-walled probasidium that is not a teliospore. The probasidium tends to collapse when empty. The basidiospores are formed at the end of tubularsterigma. Basidiospores are forcefully ejected and germinate by repetition or budding. They are thin-walled, smooth, and hyaline. Basidiospore germination results in a budding yeast state. In the hyphae the septal pore is "simple" and enclosed by a peculiar organelle with a reticulate surface, the cystosome. The salient features of Cystobasidium are the mycoparasitic association with Coprophilus ascomycetes such as Lasiobolus, Saccobolus, and Thelebolus, the transversely septate basidia and the thin-walled and persistent sac-like probasidium that tends to collapse when emptied, the production of tremelloid haustoria, and the presence of a pink yeast stage. © 2011
