The Cantharellales are an order of fungi in the class Agaricomycetes. The order includes not only the chanterelles (Cantharellaceae), but also some of the tooth fungi (Hydnaceae), clavarioid fungi, and corticioid fungi (Botryobasidiaceae). Species within the order are variously ectomycorrhizal, saprotrophic, associated with orchids, or facultative plant pathogens. Those of economic importance include edible and commercially collected Cantharellus, Craterellus, and Hydnum species as well as crop pathogens in the genera Ceratobasidium and Thanatephorus/Rhizoctonia.
The Agaricales are an order of fungi in the division Basidiomycota. As originally conceived, the order contained all the agarics, but subsequent research has shown that not all agarics are closely related and some belong in other orders, such as the Russulales and Boletales. Conversely, DNA research has also shown that many non-agarics, including some of the clavarioid fungi and gasteroid fungi belong within the Agaricales. The order has 46 extant families, more than 400 genera, and over 25,000 described species, along with six extinct genera known only from the fossil record. Species in the Agaricales range from the familiar Agaricus bisporus and the deadly Amanita virosa to the coral-like Clavaria zollingeri and bracket-like Fistulina hepatica.
The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith.
The Marasmiaceae are a family of fungi in the order Agaricales. Basidiocarps are most frequently agarics, but occasionally cyphelloid. According to a 2008 estimate, the family contained 54 genera and 1590 species, but molecular research, based on cladistic analysis of DNA sequences, has led to a more restricted family concept, so that the Marasmiaceae included just 13 genera, and some 1205 species. It was reduced further down in 2020, to 10 genera and about 700 species.
The Hygrophoraceae are a family of fungi in the order Agaricales. Originally conceived as containing white-spored, thick-gilled agarics, including Hygrophorus and Hygrocybe species, DNA evidence has extended the limits of the family, so it now contains not only agarics, but also basidiolichens and corticioid fungi. Species are thus diverse and are variously ectomycorrhizal, lichenized, associated with mosses, or saprotrophic. The family contains 34 genera and over 1000 species. None is of any great economic importance, though fruit bodies of some Hygrocybe and Hygrophorus species are considered edible and may be collected for sale in local markets.
The Bondarzewiaceae are a family of fungi in the order Russulales. The type species for both its genus and the family as a whole, Bondarzewia montana, closely resembles members of Polyporales, but has ornamented spores like those of Lactarius or Russula. This characteristic suggested the relationship between physically dissimilar species that eventually led to the restructuring of Russulales using molecular phylogeny. According to the Dictionary of the Fungi, the family contains 8 genera and 48 species.
Cantharellopsis is a tan- to whitish-colored bryophilous monotypic genus in the Hymenochaetales. The fruit bodies of the single species Cantharellopsis prescotii has a form intermediate between an Omphalina and a chanterelle (Cantharellus) because of its forked, fold-like gills. It inhabits moss on calcareous soils in temperate regions of Europe. Phylogenetically related agarics are in the genera Contumyces, Gyroflexus, Loreleia, Rickenella and Blasiphalia, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and the clavarioid genus, Alloclavaria.
Lentinellus is a genus of white rot, wood decay, lamellate agaric in the family Auriscalpiaceae, further characterized in part by rough-walled, amyloid spores produced on lamellae with jagged edges. Typically, thick-walled hyphae in the fruit body are in part amyloid, and frequently the taste of the mushrooms is acrid. The widespread genus has been estimated to contain 15 species. Mycologists Ronald Petersen and Karen Hughes considered 24 species in their 2004 world monograph of the genus.
The Hericiaceae are a family of fungi in the order Russulales. The best known genus is Hericium, species of which are valued for their medicinal properties in Oriental medicine. Taxa are mainly known from north temperate regions, and are saprobic on rotting wood. Phylogenetic analysis suggests that Hericiaceae belongs to the russuloid clade of homobasidiomycetes, and morphological and molecular evidence links it with the families Auriscalpiaceae, Bondarzewiaceae and Echinodontiaceae. Originally proposed in 1961 by Taisiya Lvovna Nikolayeva as a subfamily of Hydnaceae, Hericiaceae was formally published as a family by Marinus Anton Donk in 1964.
The Physalacriaceae are a family of fungi in the order Agaricales. Species in the family have a widespread distribution, ranging from the Arctic, (Rhizomarasmius), to the tropics, e.g. Gloiocephala, and from marine sites (Mycaureola) and fresh waters (Gloiocephala) to semiarid forests (Xerula).
The Echinodontiaceae are a family of crust fungi in the order Russulales. Species of this family, divided amongst two genera—Echinodontium and Laurilia—have a widespread distribution, although they are especially predominant in north temperate zones. They are parasitic or saprobic on wood, and may cause white rot of angiosperms and gymnosperms.
The Mycenaceae are a family of fungi in the order Agaricales. According to the Dictionary of the Fungi, the family contains 10 genera and 705 species. This is one of several families that were separated from the Tricholomataceae as a result of phylogenetic analyses. Taxa in the Mycenaceae are saprobic, have a cosmopolitan distribution, and are found in almost all ecological zones. The family was circumscribed by Caspar van Overeem in 1926.
Laxitextum is a genus of fungi in the family Hericiaceae. The widespread genus contains three species. It was circumscribed by Paul Lewis Lentz in 1955. Species in the genus have fruit bodies that are effused to reflexed and a smooth hymenium. Molecular analysis shows that the genus groups in a clade with the genera Hericium and Dentipellis.
Pseudobaeospora is a genus of fungi in the family Tricholomataceae. A 2008 estimate placed about 20 species in the widespread genus.
Episphaeria is a genus of fungus in the Agaricales. The genus is monotypic, and contains the single rare species Episphaeria fraxinicola, found in Europe. Its familial position is not known with certainty. The tiny fruit bodies of the fungus resemble minute, white cups that grow scattered or in groups on the bark of ash trees.
Flammulaster is a genus of agaricoid fungi in the family Tubariaceae. It was formerly thought to belong in the family Inocybaceae. The genus has a widespread distribution, and contains 20 species. Flammulaster was circumscribed by American mycologist Franklin Sumner Earle in 1909.
Phaeomarasmius is a genus of fungi in the family Tubariaceae. It was formerly thought to belong in the family Inocybaceae. The genus has a widespread distribution, and contains about 20 species.
Pleuroflammula is a genus of fungi in the Crepidotaceae family. The genus contains ten species found in America and Asia.
Ossicaulis is a ditypic genus of mushrooms in the family Lyophyllaceae.
