The Hymenochaetales are an order of fungi in the class Agaricomycetes. The order in its current sense is based on molecular research and not on any unifying morphological characteristics. According to one 2008 estimate, the Hymenochaetales contain around 600 species worldwide, mostly corticioid fungi and poroid fungi, but also including several clavarioid fungi and agarics. Species of economic importance include wood decay fungi in the genera Phellinus and Inonotus sensu lato, some of which may cause losses in forestry. Therapeutic properties are claimed for Inonotus obliquus ("chaga") and Phellinus linteus, both of which are now commercially marketed.
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 Auriculariales are an order of fungi in the class Agaricomycetes. Species within the order were formerly referred to the "heterobasidiomycetes" or "jelly fungi", since many have gelatinous basidiocarps that produce spores on septate basidia. Around 200 species are known worldwide, placed in six or more families, though the status of these families is currently uncertain. All species in the Auriculariales are believed to be saprotrophic, most growing on dead wood. Fruit bodies of several Auricularia species are cultivated for food on a commercial scale, especially in China.
Tremella is a genus of fungi in the family Tremellaceae. All Tremella species are parasites of other fungi and most produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the "jelly fungi". Over 100 species of Tremella are currently recognized worldwide. One species, Tremella fuciformis, is commercially cultivated for food.
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.
Ceratobasidium is a genus of fungi in the order Cantharellales. Basidiocarps are effused and the genus is sometimes grouped among the corticioid fungi, though species also retain features of the heterobasidiomycetes. Anamorphic forms were formerly referred to the genus Ceratorhiza, but this is now considered a synonym of Rhizoctonia. Ceratobasidium species, excluding the type, are also now considered synonymous with Rhizoctonia and some species have been transferred to the latter genus. Species are saprotrophic, but several are also facultative plant pathogens, causing a number of commercially important crop diseases. Some are also endomycorrhizal associates of orchids.
Rhizoctonia is a genus of fungi in the order Cantharellales. Species form thin, effused, corticioid basidiocarps, but are most frequently found in their sterile, anamorphic state. Rhizoctonia species are saprotrophic, but some are also facultative plant pathogens, causing commercially important crop diseases. Some are also endomycorrhizal associates of orchids. The genus name was formerly used to accommodate many superficially similar, but unrelated fungi.
The Ceratobasidiaceae are a family of fungi in the order Cantharellales. All species within the family have basidiocarps that are thin and effused. They have sometimes been included within the corticioid fungi or alternatively within the "heterobasidiomycetes". Species are saprotrophic, but some are also facultative plant pathogens or are associated with orchid mycorrhiza. Genera of economic importance include Ceratobasidium and Rhizoctonia, both of which contain plant pathogenic species causing diseases of commercial crops and turf grass.
Mycogelidium is a genus of fungi in the order Capnodiales. It contains the single species Mycogelidium sinense, described from China. The species was originally misinterpreted as a basidiomycete in the order Atractiellales and placed in its own family, the Mycogelidiaceae. Septate conidiophores were mistaken for auricularioid basidia. The species is now considered to belong within the anamorphic Capnodiales.
Basidiopycnides is a genus of fungi in the Phleogenaceae family. The genus is monotypic, containing the single species Basidiopycnides albertensis. The species was isolated from bark beetles collected in Banff National Park.
Proceropycnis is a genus of fungi in the family Hoehnelomycetaceae. The genus is known from Spain, North America, and east Asia.
Tulasnella is a genus of effused (patch-forming) fungi in the order Cantharellales. Basidiocarps, when visible, are typically smooth, ceraceous (waxy) to subgelatinous, frequently lilaceous to violet-grey, and formed on the underside of fallen branches and logs. They are microscopically distinct in having basidia with grossly swollen sterigmata on which basidiospores are formed. One atypical species, Tulasnella aurantiaca, produces orange to red, gelatinous, pustular anamorphs on wood. Some species form facultative mycorrhizas with orchids and liverworts. Around 80 species of Tulasnella are known worldwide.
The Heterogastridiales are an order of fungi in the Microbotryomycetes class of the Basidiomycota. The order contains a single family, the Heterogastridiaceae, which in turn contains five genera. Both the family and the order were circumscribed in 1990.
Botryobasidium is a genus of corticioid fungi belonging to the order Cantharellales. Basidiocarps are ephemeral and typically form thin, web-like, white to cream, effused patches on the underside of fallen branches, logs, and leaf litter. Several species form anamorphs producing chlamydospores. All species are wood- or litter-rotting saprotrophs and the genus has a worldwide distribution.
Eocronartium muscicola is a species of fungus belonging to the order Platygloeales. It is currently the only species in the monotypic genus Eocronartium. In the UK its recommended English name is moss rust. The species forms clavarioid basidiocarps on mosses, on which it is parasitic.
Phaeotremella is a genus of fungi in the family Phaeotremellaceae. All Phaeotremella species are parasites of other fungi and produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the "jelly fungi". Fifteen or so species of Phaeotremella are currently recognized worldwide.
The Spiculogloeomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class consists of a single order, the Spiculogloeales. Which contains one family, SpiculogloeaceaeDenchev, 2009, which holds 2 genera; Phyllozyma and Spiculogloea.
Platygloea is a genus of fungi belonging to the class Pucciniomycetes. Basidiocarps of the type species are disc-shaped, gelatinous, and occur on dead wood, probably as a saprotroph. Microscopically, all species of Platygloea sensu lato have auricularioid basidia. Currently the genus contains a heterogeneous mix of auricularioid fungi not yet accommodated in other genera.
The Hoehnelomycetaceae are a family of fungi in the order Atractiellales. The family currently contains three genera and ten species. Basidiocarps are minute and ether stilboid (pin-shaped) or pycnidioid (flask-shaped). Microscopically they produce auricularioid basidia. The type genus, Hoehnelomyces, is a synonym of Atractiella. Molecular research, based on cladistic analysis of DNA sequences, has shown that the Hoehnelomycetaceae are monophyletic. The family has a worldwide distribution.
