Sporidiales was an order in the kingdom of Fungi. It contained the family Sporidiobolaceae.
The Cuniculitremaceae are a family of fungi in the order Tremellales. There are three genera in the family. Sterigmatosporidium polymorphum parasitizes other fungi growing in insect galleries in wood. It does not produce basidiocarps, but has septate basidia similar to those found in the genus Tremella. Most species are known only from their yeast states.
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.
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 Microbotryomycetes are class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. Until recently, the class contained four orders: the Heterogastridiales, the Leucosporidiales, the Microbotryales, and the Sporidiobolales, which contained a total of 4 families, 25 genera, and 208 species. The order Kriegeriales, containing two families, Kriegeriaceae and Camptobasidiaceae, was defined in 2012.
Bulleribasidium is a genus of fungi in the family Bulleribasidiaceae. The genus currently contains some eleven species. The type species is a parasite of other fungi, its teleomorph having septate basidia and haustorial cells on its hyphae that connect to the host hyphae. Most species are, however, only known from their yeast states.
Kwoniella is a genus of fungi in the family Cryptococcaceae. The genus originally contained the single species Kwoniella mangrovensis, found in the Florida Everglades and The Bahamas. Molecular research, based on cladistic analysis of DNA sequences, has however, now extended the genus to eleven species, most known only from their yeast states.
The Sporidiobolales are an order of fungi in the subdivision Pucciniomycotina. The order contains a single family, the Sporidiobolaceae, which currently contains three genera. Most species are known only from their yeast states. Hyphal states produce teliospores from which auricularioid basidia emerge, bearing basidiospores. Species occur worldwide and have been isolated from a wide variety of substrates. Two species, Rhodotorula mucilaginosa and R. glutinis, have been known to cause disease in humans.
Leucosporidium is a genus of fungi in the subdivision Pucciniomycotina. The genus comprises fungi that are mostly known from their yeast states, though some produce hyphal states in culture that give rise to teliospores from which auricularioid basidia emerge. Species known only from their anamorphic yeast states were formerly referred to the genus Leucosporidiella, but, following changes to the International Code of Nomenclature for algae, fungi, and plants, the practice of giving different names to teleomorph and anamorph forms of the same fungus was discontinued, meaning that Leucosporidiella became a synonym of the earlier name Leucosporidium. Species have been isolated predominantly from cold environments and are regarded as psychrotolerant.
The Kriegeriales are an order of fungi in the subdivision Pucciniomycotina. Most species are known only from their yeast states and can be found in a variety of habitats, ranging from arctic waters to tropical ferns. Hyphal states produce auricularioid basidia.
Mrakia frigida is a species of fungus in the order Cystofilobasidiales. The species occurs in both a yeast and hyphal state, the latter producing teliospores from which basidia emerge. It was originally isolated in its yeast state from Antarctic snow.
Lichenostigmatales is an order of fungi in the class Arthoniomycetes. It contains the single family Phaeococcomycetaceae. Lichenostigmatales was circumscribed in 2014 by Damien Ertz, Paul Diederich, and James D. Lawrey, with genus Lichenostigma assigned as the type. Using molecular phylogenetics, they identified a lineage of taxa in the Arthoniomycetes that were phylogenetically distinct from the order Arthoniales. Species in the Lichenostigmatales include black yeasts, lichenicolous, and melanised rock-inhabiting species.
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.
Pseudotremella is a genus of fungi in the family Bulleraceae. All Pseudotremella species are parasites of other fungi and produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the "jelly fungi". Four species of Pseudotremella are currently recognized worldwide. Two of these species are, as yet, only known from their yeast states.
Ruineniaceae is a family of fungi in the order Agaricostilbales. The family contains a single genus. Species are known only from their yeast states.
Mrakia is a genus of fungi in the order Cystofilobasidiales. The genus comprises yeasts, some of which have a hyphal state forming teliospores from which basidia arise. Mrakia species are typically psychrophilic, many originally isolated from glaciers and frigid environments, and are capable of low-temperature fermentation, making them of potential interest in brewing and bioremediation.
The Cystobasidiaceae are a family of fungi in the order Cystobasidiales. The family currently comprises two genera, both of which contain fungal parasites with auricularioid basidia, some of which are known only from their yeast states.
Cystobasidium is a genus of fungi in the order Cystobasidiales. The type species is a fungal parasite forming small gelatinous basidiocarps on various ascomycetous fungi on dung. Microscopically, it has auricularioid basidia producing basidiospores that germinate by budding off yeast cells. Other species are known only from their yeast states. The yeasts Cystobasidium minutum and C. calyptogenae are rare but known human pathogens.
The Kriegeriaceae are a family of fungi in the subdivision Pucciniomycotina. The family currently comprises four genera, one of which (Kriegeria) contains a plant pathogenic species with auricularioid basidia. The other genera contain species currently known only from their yeast states.
The Camptobasidiaceae are a family of fungi in the subdivision Pucciniomycotina. The family currently comprises two genera, one of which (Camptobasidium) contains an aquatic, hyphal species with auricularioid basidia. The other genus contains species currently known only from their yeast states.
