Basidiomycota genera

Puccinia is a genus of fungi. All species in this genus are obligate plant pathogens and are known as rusts. The genus contains about 4000 species.

Ustilago is a genus of approximately 200 smut fungi, which are parasitic on grasses. 170 species are accepted by Wijayawardene et al. 2020; After phylogenetic research certain species in Ustilago, Macalpinomyces, and other genera in the Ustilaginaceae clade have been moved to other genera such as Mycosarcoma.

Cryptococcus (from Ancient Greek κρυπτός (kruptós), meaning "hidden", and κόκκος (kókkos), meaning "grain") is a genus of fungi in the family Cryptococcaceae that includes both yeasts and filamentous species. The filamentous, sexual forms or teleomorphs were formerly classified in the genus Filobasidiella, while Cryptococcus was reserved for the yeasts. Most yeast species formerly referred to Cryptococcus have now been placed in different genera. Some Cryptococcus species cause a disease called cryptococcosis.

Uromyces is a genus of rust fungi in the family Pucciniaceae. The genus was described by Franz Unger in his 1833 work Die Exantheme der Pflanzen. They have a worldwide distribution but large occurrences happen in North America and Europe.

Malassezia is a genus of fungi (specifically, a yeast belonging to the division Basidiomycota).

Gymnosporangium is a genus of heteroecious plant-pathogenic fungi which alternately infect members of the family Cupressaceae, primarily species in the genus Juniperus (junipers), and members of the family Rosaceae in the subfamily Amygdaloideae (apples, pears, quinces, shadbush, hawthorns, rowans and their relatives). The common name cedar-apple rusts has been used for these fungi. According to the Dictionary of the Fungi (10th edition, 2008), there were 57 species in the genus. In 2023, Species Fungorum lists up to 74 species.

Cronartium is a genus of rust fungi in the family Cronartiaceae.

Phragmidium is a genus of rust fungus that typically infects plant species in the family Rosaceae. It is characterised by having stalked teliospores borne on telia each having a row of four or more cells. All species have a caeoma which is a diffuse aecidium lacking a peridium.

Microscopically they have auricularioid (laterally septate) basidia. Asexual anamorphs, formerly referred to the genus Thanatophytum, produce sclerotia. Conidia-bearing anamorphs are parasitic on rust fungi and are currently still referred to the genus Tuberculina.

Cerinomyces is a genus of fungi in the order Dacrymycetales. Species are saprotrophs and occur on dead wood. As originally conceived, the genus comprised species of the Dacrymycetes having effused, corticioid basidiocarps (fruit bodies). Molecular research, based on cladistic analysis of DNA sequences, has however shown that this circumscription is not valid. As a result, the genus now contains some (but not all) species having corticioid basidiocarps and some additional species (previously referred to Dacrymyces) with gelatinous, pustular basidiocarps. Around 30 species have been described wo

Helicogloea is a genus of fungi in the family Phleogenaceae. Basidiocarps (fruit bodies) are gelatinous, effused or pustular, and (microscopically) have unclamped hyphae and basidia that are auricularioid (tubular and laterally septate). Some species form asexual anamorphs producing conidia. The widespread genus contains more than 20 species.

Ditiola is a genus of fungi in the family Dacrymycetaceae. The genus contains about 10 widely distributed species. Ditiola was circumscribed by Elias Fries in 1822.

Syzygospora is a genus of fungi in the family Filobasidiaceae. Circumscribed by the American mycologist George Willard Martin in 1937, the genus is characterized by its gelatinous fruiting bodies that often form galls on host organisms. Syzygospora species possess distinctive features such as thin-walled hyphae with clamp connections, haustorial branches, and a hymenium containing probasidia that develop into elongated, club-shaped basidia. The genus has undergone taxonomic revisions, including the synonymization of Christiansenia and the transfer of some lichenicolous (lichen-dwelling) specie

Melampsorella is a genus of plant pathogenic fungi belonging to the family Pucciniastraceae.

Bullera is a genus of fungi in the family Bulleraceae. The genus, which comprises both anamorphic and teleomorphic forms, formerly contained some 35 species. Molecular research, based on cladistic analysis of DNA sequences, has however assigned most of these species elsewhere and reduced the genus Bullera to just four species. Anamorphic forms are yeasts; teleomorphic forms (formerly referred to Bulleromyces) produce septate basidia resembling those of Tremella species, but are not known to produce basidiocarps (fruit bodies).

Alloclavaria is a clavarioid genus in the Hymenochaetales recently segregated from Clavaria by molecular analysis. Phylogenetically related fungi are in the agaricoid genera Rickenella, Contumyces, Gyroflexus, Loreleia, Cantharellopsis and Blasiphalia, as well as the stipitate stereoid genera Cotylidia and Muscinupta. The only species as yet placed in Alloclavaria is the type, formerly known as Clavaria purpurea under which name it is often cited or illustrated.. It is suspected, via circumstantial evidence, i.e. habitat, but not proven, that Alloclavaria is mycorrhizal.

Caeoma is a genus of rust fungi.

Phaeotremella is a genus of fungi in the family Phaeotremellaceae. All Phaeotremella species are parasites of other fungi and produce anamorphic yeast states. Basidiocarps (fruit bodies), when produced, are gelatinous and are colloquially classed among the "jelly fungi". Fifteen or so species of Phaeotremella are currently recognized worldwide. Tremella sanguinea, shown to be a Phaeotremella species by DNA sequencing, is cultivated in China as an ingredient in traditional Chinese medicine.

Bauerago is a genus of fungi found in the family Microbotryaceae. It contained 9 species before being reduced to 5 species.

Uromycladium is a genus of rust fungi in the family Pileolariaceae. It was circumscribed by mycologist Daniel McAlpine in 1905. The genus was established by McAlpine for rusts on Acacia (Fabaceae, subfamily Mimosoideae) with teliospores that clustered at the top of a pedicel.
