Spores of Bauerago vuyckii

The Microbotryomycetes are a class of the mushroom (Basidiomycota).

Features and way of life

The Microbotryomycetes are a morphologically and ecologically very diverse group. The spore formation ranges from basidia , which are formed by individual teliospores , to scattered basidia, to complex, pycnidia-like fruiting bodies. The majority of the species is dimorphic, so has two growth forms. The yeast form occurs in the haploid phase. All sexual species ( teleomorphs ) form phragmobasidia , with the exception of curvibasidium .

Many species have organelles in their cells called colacosomes, which are related to the fungal parasitic way of life of these species. They are membrane-bound and connect the hyphae of the parasite with those of the host.

The class includes fungal and plant parasites, and possibly saprobionts . Fungal parasitism is viewed within the class as the original way of life from which plant parasitism evolved. The occurrence of saprobionts is not certain, as the saprobiontic way of life was only observed in culture.

Systematics

The Microbotryomycetes are a monophyletic group, and the sister taxon of the Classiculomycetes . The Microbotryomycetes comprise four orders with the following families and genera:

• Heterogastridiales : mycoparasitic, with colacosomes, without teliospores.
  • Heterogastridiaceae
    • Atractocolax
    • Colacogloea
    • Heterogastridium
    • Krieglsteinera
• Microbotryales : plant parasites, without colacosomes, with teliospores.
  • Microbotryaceae : without septal pores
    • Bauerago
    • Liroa
    • Microbotryum
    • Sphacelotheca
    • Zundeliomyces
  • Ustilentylomataceae
    • Aurantiosporum
    • Fulvisporium
    • Ustilentyloma
• Leucosporidiales : with colacosomes and teliospores; Cultures white to off-white.
  • Leucosporidiaceae
    • Leucosporidiella ( anamorphic )
    • Leucosporidium (partly)
    • Mastigobasidium
• Sporidiobolales : with colacosomes and teliospores; Cultures pink.
  • Sporidiobolaceae
    • Rhodosporidium
    • Rhodotorula (partly, anamorphic)
    • Sporidiobolus
    • Sporidiobolomyces (partly, anamorphic)

The following are not assigned to any order:

• Camptobasidium
• Curvibasidium
• Kriegeria
• Leucosporidium antarcticum
• Leucosporidium fasciculatum
