The Thelephorales are an order of fungi in the class Agaricomycetes. The order includes corticioid and hydnoid fungi, together with a few polypores and clavarioid species. Most fungi within the Thelephorales are ectomycorrhizal. None is of any great economic importance, though Sarcodon imbricatus is edible and commercially marketed, whilst several species have been used for craft dyeing.

Taxonomy

History

Though "the Thelephorales" were referred to in passing by E.J.H. Corner in 1968, [1] the order was not formally published till 1976 when German mycologist Franz Oberwinkler first described it as encompassing the families Thelephoraceae and Bankeraceae. As originally conceived, species within the order had diverse basidiocarp (fruit body) forms, but shared several features in common, notably similarities in basidiospore shape (most having spiny to warted, often lobed spores) and similarities in basidiocarp colours, linked to the presence of thelephoric acid derivatives and often accompanied by blue to greenish reactions with alkalis. [2]

Current status

Molecular research, based on cladistic analysis of DNA sequences, has supported the morphological concept of the Thelephorales, indicating that the order forms a distinct grouping within the Agaricomycetes, close to the Polyporales. [3] [4] [5]

Distribution and habitat

All fungi within the order are ectomycorrhizal, forming mutually beneficial associations with the roots of living trees. [3] Distribution of the Thelephorales is cosmopolitan. According to a 2008 estimate, the order contains 18 genera and over 250 species worldwide. [6]

Economic importance

Sarcodon imbricatus is an edible species collected for local markets in some countries and commercially collected in China for export as a dried product. [7] Polyozellus multiplex is also edible and collected for sale in North America. [8] Several species within the Thelephorales have been used for dyeing wool by modern craft-dyers, including Hydnellum caeruleum in North America, [9] Sarcodon squamosus in Scandinavia, [10] and Thelephora palmata in Scotland.

<span class="mw-page-title-main">Cantharellaceae</span> 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.

<span class="mw-page-title-main">Cantharellales</span> Order of fungi

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.

<span class="mw-page-title-main">Polyporales</span> Order of fungi

The Polyporales are an order of about 1800 species of fungi in the division Basidiomycota. The order includes some polypores as well as many corticioid fungi and a few agarics. Many species within the order are saprotrophic, most of them wood-rotters. Some genera, such as Ganoderma and Fomes, contain species that attack living tissues and then continue to degrade the wood of their dead hosts. Those of economic importance include several important pathogens of trees and a few species that cause damage by rotting structural timber. Some of the Polyporales are commercially cultivated and marketed for use as food items or in traditional Chinese medicine.

<span class="mw-page-title-main">Clavariaceae</span> Family of fungi

The Clavariaceae are a family of fungi in the order Agaricales. Originally the family contained most of the clavarioid fungi, but in its current sense is more restricted, albeit with a greater diversity of basidiocarp forms. Basidiocarps are variously clavarioid or agaricoid (mushroom-shaped), less commonly corticioid or hydnoid.

<span class="mw-page-title-main">Clavulinaceae</span> 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.

<span class="mw-page-title-main">Agaricomycetes</span> Class of fungi

The Agaricomycetes are a class of fungi in the division Basidiomycota. The taxon is roughly identical to that defined for the Homobasidiomycetes by Hibbett & Thorn, with the inclusion of Auriculariales and Sebacinales. It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. Within the subdivision Agaricomycotina, which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes, which are generally considered to be jelly fungi. However, a few former "jelly fungi", such as Auricularia, are classified in the Agaricomycetes. According to a 2008 estimate, Agaricomycetes include 17 orders, 100 families, 1147 genera, and about 21000 species. Modern molecular phylogenetic analyses have been since used to help define several new orders in the Agaricomycetes: Amylocorticiales, Jaapiales, Stereopsidales, and Lepidostromatales.

<span class="mw-page-title-main">Sarcodon imbricatus</span> Species of fungus

Sarcodon imbricatus, commonly known as the shingled hedgehog or scaly hedgehog, is a species of tooth fungus in the order Thelephorales. The mushroom is edible. Many sources report it has a bitter taste, but others have found it delicious and suspect that the bitter specimens may be similar related species. The mushroom has a large, brownish cap with large brown scales and may reach 30 cm (12 in) in diameter. On the underside it sports greyish, brittle teeth instead of gills, and has white flesh. Its spore print is brown. It is associated with spruce (Picea), appearing in autumn. It ranges throughout North America and Europe, although collections from the British Isles are now assigned to the similar species Sarcodon squamosus.

<i>Hydnellum</i> Genus of fungi in the family Bankeraceae

Hydnellum is a genus of tooth fungi in the family Bankeraceae. Widely distributed in the Northern Hemisphere, the genus contains around 40 species. The fruitbodies of its members grow by slowly enveloping nearby bits of grass and vegetation. There is great variability in the form of Hydnellum fruitbodies, which are greatly influenced by environmental conditions such as rainfall and humidity, drying winds, and temperature. They are too tough and woody to eat comfortably. Several species have become the focus of increasing conservation concern following widespread declines in abundance.

<span class="mw-page-title-main">Hydnaceae</span> 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.

<span class="mw-page-title-main">Atheliaceae</span> Family of fungi

Atheliaceae is a family of corticioid fungi placed under the monotypic order Atheliales. Both the order and the family were described by Walter Jülich in 1981. According to a 2008 estimate, the family contains 20 genera and approximately 100 species. However, many genera formerly considered to belong in the Atheliaceae have since been moved to other families, including Amylocorticiaceae, Albatrellaceae, and Hygrophoraceae. Despite being a relatively small group with inconspicuous forms, Atheliaceae members show great diversity in life strategies and are widespread in distribution. Additionally, being a group strictly composed of corticioid fungi, they may also provide insights on the evolution of fruiting body forms in basidiomycetes.

<span class="mw-page-title-main">Bankeraceae</span> Family of fungi

The Bankeraceae are a family of fungi in the order Thelephorales. Taxa are terrestrial, and ectomycorrhizal with plant species in families such as Pinaceae or Fagaceae. The family was circumscribed by Marinus Anton Donk in 1961. According to a 2008 estimate, the family contains 6 genera and 98 species.

<span class="mw-page-title-main">Auriculariales</span> Order of fungi

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.

<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, 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.

<i>Sarcodon</i> Genus of fungi

Sarcodon is a genus of fungi in the family Bankeraceae, which is part of the order Thelephorales known for its almost universal ectomycorrhizal life style. The genus owes its name to the presence of teeth-like spines on the hymenophore, it is derived from ancient Greek; sarco = flesh and odon = tooth. This is why they are commonly called "tooth fungi", or "Hydnoid fungi".

<i>Polyozellus</i> Genus of fungus

Polyozellus is a fungal genus in the family Thelephoraceae, a grouping of mushrooms known collectively as the leathery earthfans. Previously considered a monotypic genus, it now contains the Polyozellus multiplex species complex. The genus name is derived from the Greek poly meaning many, and oz, meaning branch. It is commonly known as the blue chanterelle, the clustered blue chanterelle, or, in Alaska, the black chanterelle. The distinctive fruit body of this species comprises blue- to purple-colored clusters of vase- or spoon-shaped caps with veiny wrinkles on the undersurface that run down the length of the stem.

<span class="mw-page-title-main">Hydnoid fungi</span> 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.

<span class="mw-page-title-main">Tulasnellaceae</span> 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>Thelephora palmata</i> Species of clavarioid fungus

Thelephora palmata is a species of clavarioid fungus in the family Thelephoraceae. The fruit bodies are leathery and coral-like, with branches that are narrow at the base before widening out like a fan and splitting into numerous flattened prongs. The wedge-like tips are whitish when young, but darken as the fungus matures. The common names of the fungus refers to its pungent odor, likened to fetid garlic. A widely distributed but uncommon species, it is found in Asia, Australia, Europe, North America, and South America, where it fruits on the ground in both coniferous and mixed forest.

<i>Hydnellum cristatum</i> Species of fungus

Hydnellum cristatum is a tooth fungus in the family Bankeraceae found in Europe and North America. It was originally described as a species of Hydnum by Italian mycologist Giacomo Bresadola in 1902. Joost Stalpers transferred it to the genus Hydnellum in 1993.

Sarcodon dissimulans is a species of tooth fungus in the family Bankeraceae. Found in Nova Scotia, Canada, it was described as new to science in 1984 by mycologist Kenneth A. Harrison. It is characterized as having an "extremely nauseating" taste. Its spores are roughly spherical to oblong, measuring 5–6 by 4–5 µm.
