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 (Aphelariaceae and Clavulinaceae), 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 ).

Taxonomy

The order was originally proposed in 1926 by German mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota having "stichic" basidia (basidia with nuclear spindles arranged longitudinally). On this basis, he included three families within the Cantharellales: the Cantharellaceae (including the Hydnaceae), the Clavulinaceae, and the Exobasidiaceae. [1] The last group are now placed within the Exobasidiales. [2]

By 1995, the order had been amended (based on micromorphological research) to include not only the Cantharellaceae, but also the Aphelariaceae, Clavariaceae, Clavariadelphaceae, Clavulinaceae, Craterellaceae, Hydnaceae, Physalacriaceae, Pterulaceae, Scutigeraceae, Sparassidaceae, and Typhulaceae. [3]

Current status

Molecular research, based on cladistic analysis of DNA sequences, has redefined the Cantharellales. [4] As well as the Cantharellaceae (chanterelles and their allies, inclusive of the Craterellaceae), the order currently comprises fungi with morphologically diverse sporocarps (fruit bodies) within the Aphelariaceae (clavarioid fungi), Botryobasidiaceae (corticioid fungi), Ceratobasidiaceae (heterobasidiomycetes), Clavulinaceae (clavarioid fungi), Hydnaceae (tooth fungi), and Tulasnellaceae (heterobasidiomycetes). The Clavariaceae, Physalacriaceae, Pterulaceae, and Typhulaceae, previously included within the order, are now placed within the Agaricales; the Clavariadelphaceae are now in the Gomphales; the Sparassidaceae in the Polyporales. The Scutigeraceae have been replaced by the Albatrellaceae within the Russulales. [2] According to a 2008 estimate, the order contains 7 families, 38 genera, and 544 species. [5]

Habitat and distribution

Most fungi within the order are ectomycorrhizal, forming mutually beneficial associations with certain trees, shrubs, and other vascular plants. [6] Species in the Botryobasidiaceae are believed to be saprotrophs of fallen wood and leaf litter. [7] Species in the Ceratobasidiaceae are also saprotrophs, but some are capable of becoming facultative plant pathogens. Species in the Tulasnellaceae are saprotrophic, but are also associated with orchid mycorrhiza, as are some species in the Ceratobasidiaceae. [8] Distribution is cosmopolitan.

Economic importance

Sporocarps (fruit bodies) of chanterelles and some Hydnum species, particularly Hydnum repandum , are edible and widely collected on a commercial scale. They are marketed fresh or processed and traded internationally. [6] [9] Several species in the Ceratobasidiaceae, notably Rhizoctonia solani , cause significant diseases of cereals and other commercial crops, as well as turf grass. [8] [10]

Genera incertae sedis

Some genera of the Cantharellales have not been assigned to any family, i.e., they are incertae sedis with respect to familial placement:

Cantharellaceae Family of fungi

The Cantharellaceae are a family of fungi in the order Cantharellales. The family contains the chanterelles and related species, a group of fungi that superficially resemble agarics but have smooth, wrinkled, or gill-like hymenophores. Species in the family are ectomycorrhizal, forming a mutually beneficial relationship with the roots of trees and other plants. Many of the Cantharellaceae, including the chanterelle, the Pacific golden chanterelle, the horn of plenty, and the trumpet chanterelle, are not only edible, but are collected and marketed internationally on a commercial scale.

<i>Cantharellus</i> Genus of fungi

Cantharellus is a genus of popular edible mushrooms, commonly known as chanterelles, a name which can also refer to the type species, Cantharellus cibarius. They are mycorrhizal fungi, meaning they form symbiotic associations with plants, making them very difficult to cultivate. Caution must be used when identifying chanterelles for consumption due to lookalikes, such as the Jack-O-Lantern species, which can make a person very ill. Despite this, chanterelles are one of the most recognized and harvested groups of edible mushrooms.

Hymenochaetales Order of fungi

The Hymenochaetales are an order of fungi in the class Agaricomycetes. The order in its current sense is based on molecular research and not on any unifying morphological characteristics. According to one 2008 estimate, the Hymenochaetales contain around 600 species worldwide, mostly corticioid fungi and poroid fungi, but also including several clavarioid fungi and agarics. Species of economic importance include wood decay fungi in the genera Phellinus and Inonotus sensu lato, some of which may cause losses in forestry. Therapeutic properties are claimed for Inonotus obliquus ("chaga") and Phellinus linteus, both of which are now commercially marketed.

<i>Hydnum repandum</i> Species of edible fungus of the family Hydnaceae distributed in Europe

Hydnum repandum, commonly known as the sweet tooth, wood hedgehog or hedgehog mushroom, is a basidiomycete fungus of the family Hydnaceae. First described by Carl Linnaeus in 1753, it is the type species of the genus Hydnum. The fungus produces fruit bodies (mushrooms) that are characterized by their spore-bearing structures—in the form of spines rather than gills—which hang down from the underside of the cap. The cap is dry, colored yellow to light orange to brown, and often develops an irregular shape, especially when it has grown closely crowded with adjacent fruit bodies. The mushroom tissue is white with a pleasant odor and a spicy or bitter taste. All parts of the mushroom stain orange with age or when bruised.

Clavariaceae Family of fungi

The Clavariaceae are a family of fungi in the order Agaricales. Collectively, they are commonly known as coral fungi due to their resemblance to aquatic coral, although other vernacular names including antler fungi, finger fungi, worm mold, and spaghetti mushroom are sometimes used for similar reasons.

Clavulinaceae Family of fungi

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.

Waitea circinata is a species of fungus in the family Corticiaceae. Basidiocarps are thin, effused, and web-like, but the fungus is more frequently encountered in its similar but sterile anamorphic state, sometimes called Rhizoctonia zeae. Waitea circinata is best known as a plant pathogen, causing commercially significant damage to cereal crops and turf grass.

<i>Craterellus tubaeformis</i>

Craterellus tubaeformis is an edible fungus, also known as yellowfoot, winter mushroom, or funnel chanterelle. It is mycorrhizal, forming symbiotic associations with plants, making it very challenging to cultivate. It is smaller than the golden chanterelle and has a dark brown cap with paler gills and a hollow yellow stem. C. tubaeformis tastes stronger but less fruity than the golden chanterelle. It has a very distinctive smokey, peppery taste when raw. It grows in temperate and cold parts of Northern America and Europe, including Scandinavia, Finland, Russia, and the British Isles, as well as in the Himalayas in Asia, including Assam, in the central parts of the Indian subcontinent, and in Thailand.

Hydnaceae Family of fungi

The Hydnaceae are a family of fungi in the order Cantharellales. Originally the family encompassed all species of fungi that produced basidiocarps having a hymenium consisting of slender, downward-hanging tapering extensions referred to as "spines" or "teeth", whether they were related or not. This artificial but often useful grouping is now more generally called the hydnoid or tooth fungi. In the strict, modern sense, the Hydnaceae are limited to the genus Hydnum and related genera, with basidiocarps having a toothed or poroid hymenium. Species in the family are ectomycorrhizal, forming a mutually beneficial relationship with the roots of trees and other plants. Hydnum repandum is an edible species, commercially collected in some countries and often marketed under the French name pied de mouton.

Aphelariaceae Family of fungi

The Aphelariaceae are a family of fungi in the order Cantharellales. The family contains a small group of tropical and subtropical clavarioid fungi, but is not well characterized and has not been the subject of published research.

Botryobasidiaceae Family of fungi

The Botryobasidiaceae are a family of fungi in the order Cantharellales. The family contains a group of corticioid fungi that form thin, web-like basidiocarps. Some species form asexual anamorphs producing chlamydospores. All are believed to be wood-rotting or litter-rotting saprotrophs. None is known to be of any economic importance.

Auriculariaceae Family of fungi

The Auriculariaceae are a family of fungi in the order Auriculariales. Species within the family were formerly referred to the "heterobasidiomycetes" or "jelly fungi", since many have gelatinous basidiocarps that produce spores on septate basidia. Around 100 species are known worldwide. All 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.

<i>Phellodon</i> Genus of tooth fungi in the family Bankeraceae

Phellodon is a genus of tooth fungi in the family Bankeraceae. Species have small- to medium-sized fruitbodies with white spines on the underside from which spores are released. All Phellodon have a short stalk or stipe, and so the genus falls into the group known as stipitate hydnoid fungi. The tough and leathery flesh usually has a pleasant, fragrant odor, and develops a cork-like texture when dry. Neighboring fruitbodies can fuse together, sometimes producing large mats of joined caps. Phellodon species produce a white spore print, while the individual spores are roughly spherical to ellipsoid in shape, with spiny surfaces.

The Aphyllophorales is an obsolete order of fungi in the Basidiomycota. The order is entirely artificial, bringing together a miscellany of species now grouped among the clavarioid fungi, corticioid fungi, cyphelloid fungi, hydnoid fungi, and poroid fungi.

Hydnoid fungi Group of fungi

The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus Hydnum, but it is now known that not all hydnoid species are closely related.

<i>Ceratobasidium</i> Genus of fungi

Ceratobasidium is a genus of fungi in the order Cantharellales. Basidiocarps are effused and the genus is sometimes grouped among the corticioid fungi, though species also retain features of the heterobasidiomycetes. Rhizoctonia-like anamorphs of Ceratobasidium species are placed in the genus Ceratorhiza. Species are saprotrophic, but several are also facultative plant pathogens, causing a number of commercially important crop diseases. Some are also endomycorrhizal associates of orchids.

<i>Rhizoctonia</i>

Rhizoctonia is a genus of anamorphic fungi in the order Cantharellales. Species do not produce spores, but are composed of hyphae and sclerotia and are asexual states of fungi in the genus Thanatephorus. Rhizoctonia species are saprotrophic, but are also facultative plant pathogens, causing commercially important crop diseases. They are also endomycorrhizal associates of orchids. The genus name was formerly used to accommodate many superficially similar, but unrelated fungi.

Ceratobasidiaceae Family of fungi

The Ceratobasidiaceae are a family of fungi in the order Cantharellales. All species within the family have basidiocarps that are thin and effused. They have sometimes been included within the corticioid fungi or alternatively within the "heterobasidiomycetes". Species are saprotrophic, but some are also facultative plant pathogens or are associated with orchid mycorrhiza. Genera of economic importance include Ceratobasidium and Thanatephorus, both of which contain plant pathogenic species causing diseases of commercial crops and turf grass.

Tulasnellaceae Family of fungi

The Tulasnellaceae are a family of fungi in the order Cantharellales. The family comprises mainly effused (patch-forming) fungi formerly referred to the "jelly fungi" or heterobasidiomycetes. Species are wood- or litter-rotting saprotrophs, but many are also endomycorrhizal associates of orchids and some have also been thought to form ectomycorrhizal associations with trees and other plants.

<i>Clavulicium</i> Genus of fungi

Clavulicium is a genus of corticioid fungi in the family Stereopsidaceae. It was formerly placed in the family Clavulinaceae in the order Cantharellales but was found to belong in a new order along with Stereopsis in 2014. The widespread genus was circumscribed by the French mycologist Jacques Boidin in 1957. The spores and the basidia of species in the genus are similar to those in Clavulina but also similar to those in Stereopsis. Clavulicium globosum is now a species of Stereopsis.
