Pezizomycetes are a class of fungi within the division Ascomycota.
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.
Pucciniomycotina is a subdivision of fungus within the division Basidiomycota. The subdivision contains 10 classes, 21 orders, and 38 families. Over 8400 species of Pucciniomycotina have been described - more than 8% of all described fungi. The subdivision is considered a sister group to Ustilaginomycotina and Agaricomycotina, which may share the basal lineage of Basidiomycota, although this is uncertain due to low support for placement between the three groups. The group was known as Urediniomycetes until 2006, when it was elevated from a class to a subdivision and named after the largest order in the group, Pucciniales.
The Exobasidiomycetes are a class of fungi sometimes associated with the abnormal outgrowths of plant tissues known as galls. The class includes Exobasidium camelliae Shirai, the camellia leaf gall and Exobasidium vaccinii Erikss, the leaf and flower gall. There are eight orders in the Exobasidiomycetes, including the Ceraceosorales, Doassansiales, Entylomatales, Exobasidiales, Georgefischeriales, Malasseziales, Microstromatales and the Tilletiales. Four of the eight orders include smut fungi. The families Ceraceosoraceae and Malasseziaceae were formally validated in 2009 for the orders Ceraceosorales and Malasseziales, respectively.
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 Agaricostilbomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class consists of a single order, six families, and 15 genera. Most species are known only from their yeast states. Where known, basidiocarps (fruitbodies) are typically small and stilboid (pin-shaped).
The Atractiellomycetes are class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class consists of a single order, the Atractiellales, which contains 3 families, 10 genera, and 58 species.
The Classiculomycetes are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Classiculales, which in turn contains the single family Classiculaceae. The family contains two monotypic genera.
The Cryptomycocolacomycetes are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Cryptomycocolacales, which in turn contains the single family Cryptomycocolacaceae. The family has two monotypic genera.
The Cystobasidiomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. Most species are known from their yeast states; hyphal states, when present, produce auricularioid basidia and are frequently parasites of other fungi. The class contains five orders as well as two families and one genus (Queiroziella) of uncertain disposition. An additional order, Cyphobasidiales, has been proposed to accommodate several lichenicolous species, but its separation from the Erythrobasidiales has not been demonstrated.
The Microbotryomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class currently contains eight orders, plus three additional, unassigned families, plus seven additional, unassigned genera. Many species are known only from their yeast states. Species with hyphal states typically produce auricularioid basidia and are often parasitic on other fungi or plants. Several species in the genera Rhodotorula and Sporobolomyces are opportunistic human pathogens.
The Mixiomycetes are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Mixiales, which in turn contains a single family, the Mixiaceae that circumscribes the monotypic genus Mixia. Only one species has been described to date, Mixia osmundae; this species was originally named Taphrina osmundae by Japanese mycologist Toji Nishida in 1911. It is characterized by having multinucleate hyphae, and by producing multiple spores on sporogenous cells.
Pucciniomycetes is a diverse class of fungi in the subphylum Pucciniomycotina of phylum Basidiomycota. The class contains 5 orders, 21 families, 190 genera, and approximately 8,016 species. It has been estimated that this class contains about one third of all teleomorphic basidiomycetes. Pucciniomycetes contains many economically important plant pathogenic fungal rusts; the order Pucciniales is the largest clade in this class, representing approximately 7,000 species.
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.
Tuberculina is a genus of fungi in the order Helicobasidiales. The genus is a synonym of Helicobasidium, but currently species have not yet been assigned to the latter genus. Tuberculina species are conidia-bearing parasites of rust fungi, forming felt-like, purple patches on their hosts.
The Helicobasidiales are an order of fungi in the subdivision Pucciniomycotina. The order is currently monotypic, containing the single family Helicobasidiaceae which itself is monotypic, containing the single genus Helicobasidium. The anamorphic genus Tuberculina is a synonym of Helicobasidium, but species are not currently integrated in the latter genus.
Jamesdicksonia dactylidis is a species of fungus belonging to the family Georgefischeriaceae.
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 Spiculogloeomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class consists of a single order, the Spiculogloeales, together with an additional, unassigned genus, Meniscomyces. Many species are currently known only from their yeast states. Species in the genus Spiculogloea form hyphal states that produce auricularioid basidia and are parasitic on other fungi.
