The Clavulinaceae are a family of fungi in the order Cantharellales. The family is not well defined, but currently comprises species of clavarioid fungi as well as some corticioid fungi. These species are nutritionally diverse, some being ectomycorrhizal, others wood-rotting saprotrophs, others lichenized, and yet others lichenicolous.
The Paxillaceae are a family of mushroom-forming fungi bearing close affinity to the boletes. Collectively, the family contains nine genera and 78 species. The type genus is Paxillus, containing fungi with decurrent gills, and Gyrodon, which has members with decurrent pores, among others. French mycologist René Maire had erected the family in 1902, placing it between the agarics and boletes and recognizing the groups' similarities with the latter group. Maire's usage of the name was later deemed to be invalid, and the genus authority is attributed to Johannes Paulus Lotsy. Molecular research confirms the relations of Gyrodon, with the decurrent-pored mushroom G. lividus, Paragyrodon, with the type species P. sphaerosporus, and Paxillus as sister groups, together lying near the base of a phylogenetic tree from which the genus Boletus arises. The name Gyrodontaceae, published by Belgian botanist Paul Heinemann in 1951, is considered synonymous with Paxillaceae.
Omphalotus is a genus of basidiomycete mushroom formally circumscribed by Victor Fayod in 1889. Members have the traditional cap and stem toadstool form. They are saprobic, and fruit in clumps on trees. The best known and type species is the jack-o'-lantern mushroom (Omphalotus olearius). Species of Omphalotus have been mistaken for chanterelles. All Omphalotus species are presumed poisonous, causing gastrointestinal symptoms. Some Omphalotus species have bioluminescent properties.
The Corticiales are an order of fungi in the class Agaricomycetes. The order is mostly composed of corticioid fungi, but also includes one anomalous agaricoid species, Marchandiomphalina foliacea. Species within the order are generally saprotrophic, most of them wood-rotters, but several are parasitic on grasses or lichens. Those of economic importance include Waitea circinata, a pathogen of cereal crops, and Laetisaria fuciformis, the cause of red thread disease in turf grass.
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.
The Mortierellaceae are a family of fungi in the order Mortierellales. The family contains six genera and 93 species.
Phlebia is a genus of mostly crust fungi in the family Meruliaceae. The genus has a widespread distribution. Phlebia species cause white rot.
Rhodotus is a genus in the fungus family Physalacriaceae. It is a monotypic genus and consists of the single mushroom species Rhodotus palmatus, known in the vernacular as the netted rhodotus, the rosy veincap, or the wrinkled peach. This uncommon species has a circumboreal distribution, and has been collected in eastern North America, northern Africa, Europe, and Asia; declining populations in Europe have led to its appearance in over half of the European fungal Red Lists of threatened species. Typically found growing on the stumps and logs of rotting hardwoods, mature specimens may usually be identified by the pinkish color and the distinctive ridged and veined surface of their rubbery caps; variations in the color and quantity of light received during development lead to variations in the size, shape, and cap color of fruit bodies.
Hygrophoropsis is a genus of gilled fungi in the family Hygrophoropsidaceae. It was circumscribed in 1888 to contain the type species, H. aurantiaca, a widespread fungus that, based on its appearance, has been affiliated with Cantharellus, Clitocybe, and Paxillus. Modern molecular phylogenetic analysis shows that the genus belongs to the suborder Coniophorineae of the order Boletales.
Rhizomarasmius is a genus of fungi in the family Physalacriaceae, containing about five species.
Nia vibrissa is a species of fungus in the order Agaricales. The species is adapted to a marine environment and is a wood-rotting fungus, producing small, gasteroid basidiocarps on driftwood, submerged timber, mangrove wood, and similar substrates. The spores have long, hair-like projections and are widely dispersed in sea water, giving Nia vibrissa a cosmopolitan distribution.
Cribbea is a genus of secotioid fungi in the family Physalacriaceae. The genus has a widespread distribution in southern temperate areas, and, according to a 2008 estimate, contains four species. A new species, Cribbea turbinispora, was reported from Australia in 2009, and in the same publication, C. lamellata was synonymized with C. gloriosa. The genus is named after mycologist Joan Cribb, in recognition of her contribution to fungal taxonomy.
Rozella is a fungal genus of obligate endoparasites of a variety of hosts, including Oomycota, Chytridiomycota, and Blastocladiomycota. Rozella was circumscribed by French mycologist Marie Maxime Cornu in 1872. Considered one of the earliest diverging lineages of fungi, the widespread genus contains 27 species, with the most well studied being Rozella allomycis. Rozella is a member of a large clade of fungi referred to as the Cryptomycota/Rozellomycota. While some can be maintained in dual culture with the host, most have not been cultured, but they have been detected, using molecular techniques, in soil samples, and in freshwater and marine ecosystems. Zoospores have been observed, along with cysts, and the cells of some species are attached to diatoms.
Pierre Clement Augustin Dangeard was a botanist and mycologist known for his investigations of sexual reproduction in fungi. He was the father of botanist Pierre Dangeard (1895–1970) and geologist Louis Dangeard (1898–1987).
Paraxerula is a genus of fungi in the family Physalacriaceae. It was circumscribed in 2010 by mycologist Ron Petersen to replace Xerula section Hyalosetae, proposed by Heinrich Dörfelt in 1984. Petersen originally included P. caussei, P. hongoi, and the type species P. americana. The Chinese species P. ellipsospora was added to the genus in 2014.
