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.
Papiliotrema is a genus of fungi in the family Rhynchogastremaceae. Filamentous states, where known, form septate basidia with haustorial cells indicating they are parasites of other fungi. Most species are currently known only from their yeast states. More than 20 species have been referred to Papiliotrema.
The Leucosporidiales are an order of fungi in the class Microbotryomycetes. The order contains a single family, the Leucosporidiaceae, which in turn contains a single genus, Leucosporidium. The order 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.
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.
The Agaricostilbales are an order of fungi in the class Agaricostilbomycetes. The order consists of six families and 15 genera.
The Chionosphaeraceae are a family of fungi in the order Agaricostilbales. The family contains six genera. Some species form small, stilboid (pin-shaped) fruitbodies. Others are known only from their yeast states.
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. Tremella sanguinea, shown to be a Phaeotremella species by DNA sequencing, is cultivated in China as an ingredient in traditional Chinese medicine.
The Holtermanniales are an order in the fungal class Tremellomycetes. The order contains two genera. Species of Holtermannia produce groups of horn-like gelatinous basidiocarps on wood and have associated yeast states. Species of Holtermaniella are only known as yeasts.
Naematelia is a genus of fungi in the family Naemateliaceae. All Naematelia species are parasites of other fungi and produce anamorphic yeast states. When produced, Basidiocarps ,, are gelatinous and are colloquially classed among the "jelly fungi."Four species of Naematelia are currently recognized worldwide. One species, Naematelia aurantialba, is commercially cultivated for food.
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.
Solicoccozyma is a genus of fungi in the family Piskurozymaceae. Species have only been isolated in their yeast states, several of which were formerly referred to the genus Cryptococcus, but can produce filamentous states with basidia in culture. Nine species have been described worldwide.
Jianyuniaceae is a family of fungi in the order Agaricostilbales. The family contains three genera. Species are known only from their yeast states.
The Spiculogloeales are an order of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The order is currently monotypic, consisting of a single family, the Spiculogloeaceae. Species in the genus Phyllozyma 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.
Phaffia is a genus of fungi in the order Cystofilobasidiales. The genus comprises orange-red yeasts that form basidia directly from yeast cells, lack hyphae throughout their life cycle, and produce astaxanthin, a carotenoid used as an additive in animal feed to enhance colour in shrimp, salmon, and poultry eggs and also as an antioxidant in dietary supplements.
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.
Cystobasidium fimetarium is a species of fungus in the order Cystobasidiales. It 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. The species is known from Europe and North America.
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.
