Cystobasidiales

The Cystobasidiales are an order of fungi within the class Cystobasidiomycetes, which itself is part of the subphylum Pucciniomycotina. These fungi are characterized by being parasitic on plants. A notable feature of the Cystobasidiales is that their yeasts are non-teliospore-forming and produce auricularioid basidia and ballistospores, which are forcibly discharged. Examples of genera within this order include Cystobasidium, Occultifur, and Rhodotorula. The broader phylum Basidiomycota, to which Cystobasidiales belong, is a large and diverse group of fungi that includes familiar organisms like mushrooms and puffballs, as well as rusts and smuts.12
