The Ustilaginomycotina is a subdivision within the division Basidiomycota of the kingdom Fungi. It consists of the classes Ustilaginomycetes and Exobasidiomycetes, and in 2014 the subdivision was reclassified and the two additional classes Malasseziomycetes and Monilielliomycetes added. The name was first published by Doweld in 2001; Bauer and colleagues later published it in 2006 as an isonym. Ustilagomycotina and Agaricomycotina are considered to be sister groups, and they are in turn sister groups to the subdivision Pucciniomycotina.
Thecaphora is a genus of basidiomycote fungus which contains several species of plant pathogens. The widespread genus contained about 57 species in 2008. and held 61 species in 2020.
Tilletia is a genus of smut fungi in the Tilletiaceae family. Species in this genus are plant pathogens that affect various grasses. Tilletia indica, which causes Karnal bunt of wheat, and Tilletia horrida, responsible for rice kernel smut, are examples of species that affect economically important crops.
The Entylomatales are an order of smut fungi in the class Exobasidiomycetes. A monotypic order, it consists of a single family, the Entylomataceae. Both the family and order were circumscribed in 1997.
The Georgefischeriales are an order of smut fungi in the class Exobasidiomycetes. The order consists of four families, the Eballistraceae, the Georgefischeriaceae, the Gjaerumiaceae, and the Tilletiariaceae.
The Microstromatales are order of fungi in the class Exobasidiomycetes. The order consists of three families: the Microstromataceae, the Quambalariaceae, and the Volvocisporiaceae.
The Tilletiales are an order of smut fungi in the class Exobasidiomycetes. It is a monotypic order, consisting of a single family, the Tilletiaceae, which contains seven genera. The roughly 150 species in the Tilletiales all infect hosts of the grass family, except for species of Erratomyces, which occur on legumes.
Entorrhizomycetes is the sole class in the phylum Entorrhizomycota within the Fungi subkingdom Dikarya along with Basidiomycota and Ascomycota. It contains three genera and is a small group of teliosporic root parasites that form galls on plants in the Juncaceae (rush) and Cyperaceae (sedge) families. Prior to 2015 this phylum was placed under the subdivision Ustilaginomycotina. A 2015 study did a "comprehensive five-gene analyses" of Entorrhiza and concluded that the former class Entorrhizomycetes is possibly either a close sister group to the rest of Dikarya or Basidiomycota.
The Ustilaginaceae are a family of smut fungi in the order Ustilaginomycetes. Collectively, the family contains 17 genera and 607 species.
The Anthracoideaceae are a family of smut fungi in the order Ustilaginales. Collectively, the family contains 20 genera and 198 species. Anthracoideaceae was circumscribed by the Bulgarian mycologist Cvetomir M. Denchev in 1997.
Volvocisporiaceae is a fungal family in the class Exobasidiomycetes. The family contains the single genus Volvocisporium, which in turn contains the single species Volvocisporium triumfetticola, found on the leaves of Triumfetta rhomboidea in India.
The Exoteliospora is a monotypic, genus of smut fungi in the family Melanotaeniaceae which contains the single species Exoteliospora osmundae.
The Melanotaenium is a genus of smut fungi in the family Melanotaeniaceae.
Robert Bauer was a German mycologist, specialising in rust (Uredinales) and smut (Ustilaginomycetes) fungi.
Doassansia is a genus of fungi belonging to the family Doassansiaceae.
Farysia is a genus of fungi belonging to the family Anthracoideaceae.
The Urocystidales are an order of fungi within the class Ustilaginomycetes. The order contains 6 families and about 400 genera. They are a sister order to Ustilaginales.
The Doassansiaceae are a family of fungi in the division Basidiomycota and order of Doassansiales. The family contains 11 genera and about 58 species. They have a widespread distribution. Doassansiaceae is also known and classified as a smut fungi.
The Melaniellaceae are a family of fungi in the division Basidiomycota and order of Doassansiales. The family contains 1 genera and 2 species. They have a distribution in south and south-east Asia.
The Rhamphosporaceae is a family of fungi in the division Basidiomycota and order of Doassansiales. The monotypic family only contains 1 genus; RhamphosporaD.D.Cunn. and just 1 species, Rhamphospora nymphaeaeD.D.Cunn. It is found on the leaves of waterlilies causing spots.
