The Cystobasidiomycetes are a class of mushrooms (Basidiomycota).

Features and way of life

In the cell wall carbohydrates, fucose is absent as a component that is present in the other Pucciniomycotina. All representatives form phragmobasidia and are dimorphic, develop as two life stages: The haploid stage grows yeast-like . These colonies are pink-orange, only in Naohidea they are white. Bannoa and Erythrobasidium do not form basidia, but conidia . These two genera also have a special, hydrogenated coenzyme Q10 system, and they form a separate clade within the class .

No teleomorphs are known in this order . The anamorphic Cyrenella elegans has conidia arms spread out like spokes. Their yeast stage is orange in color. Cyrenella as well as Sakaguchia colonize water locations. Both genera form teliospores .

Several representatives are parasites on mushrooms .

Systematics

The Pucciniomycetes are the sister taxon of a group consisting of Microbotryomycetes , Mixiomycetes and Agaricostilbomycetes . The Pucciniomycetes comprise three orders:

• Cystobasidiales : anamorphic and dimorphic yeasts
  • Cystobasidiaceae
    • Occultifer
    • Rhodotorula (part)
    • Cystobasidium
• Erythrobasidiales
  • Bannoa
  • Erythrobasidium
  • Rhodotorula (part)
  • Sporobolomyces (part)
• Naohideales
  • Naohidea

Not assigned to any order:

• Cyrenella
• Sakaguchia colonizes marine locations

The relationships within the class can be found in the following cladogram :

	Erythrobasidiales      Cystobasidiales      Naohideales
