Bourdotia is a genus of fungi in the order Auriculariales. Basidiocarps (fruit bodies) are effused, waxy, and occur on dead wood. Macroscopically they resemble waxy species of Exidiopsis , but are distinguished microscopically by the presence of gloeocystidia and "myxarioid" basidia (vertically sepate with an enucleate stalk cell). Only the type species, described from France, is currently confirmed as belonging to the genus.

Taxonomy

History

Bourdotia was originally published in 1908 by Italian mycologist Giacomo Bresadola as a subgenus of Sebacina , a genus then used for any species with tremelloid (vertically septate) basidia and effused basidiocarps. It was raised to the level of genus in 1913. Many additional effused species with gloeocystidia were subsequently described in Bourdotia until 1963 when Canadian mycologist E. Robena Luck-Allen transferred the majority into the genus Basidiodendron which she considered distinct. [1]

Current status

Molecular research, based on cladistic analysis of DNA sequences, has confirmed Luck-Allen's separation of Basidiodendron and Bourdotia. [2] [3] Sequencing of the type species, Bourdotia galzinii , has shown that the genus is close to Ductifera (which also has gloeocystidia) and may not be distinct. [2]

<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.

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.

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

The Hyaloriaceae are a family of fungi in the order Auriculariales. Species within the family have gelatinous basidiocarps that produce spores on septate basidia and, as such, were formerly referred to the "heterobasidiomycetes" or "jelly fungi". All appear to be saprotrophic, growing on dead wood or plant remains. Less than 30 species are currently included within the Hyaloriaceae, but the family has not been extensively researched.

<i>Exidia</i> Genus of fungi

Exidia is a genus of fungi in the family Auriculariaceae. The species are saprotrophic, occurring in attached or recently fallen dead wood, and produce gelatinous basidiocarps. The fruit bodies are diverse, pustular, lobed, button-shaped or cup-shaped. Several species, including the type species Exidia glandulosa, have sterile pegs or pimples on their spore-bearing surface. The genus has a cosmopolitan distribution and around 20 species are currently recognized worldwide. Initial molecular research indicates the genus is artificial.

<i>Sebacina</i> Genus of fungi

Sebacina is a genus of fungi in the family Sebacinaceae. Its species are mycorrhizal, forming a range of associations with trees and other plants. Basidiocarps are produced on soil and litter, sometimes partly encrusting stems of living plants. The fruit bodies are cartilaginous to rubbery-gelatinous and variously effused (corticioid) to coral-shaped (clavarioid). The genus has a cosmopolitan distribution.


Eichleriella is a genus of fungi in the order Auriculariales. Species produce effused or cupulate, waxy to leathery basidiocarps on wood, with a smooth to spiny surface. The genus currently contains more than 15 species.


Heterochaete is a genus of fungi in the order Auriculariales. Species produce effused, gelatinous, waxy, or leathery basidiocarps on wood, partly or wholly covered in small sterile spines or pegs. The presence of these sterile spines distinguishes the genus from Exidiopsis, species of which are microscopically similar but have smooth basidiocarps.

<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. Anamorphic forms were formerly referred to the genus Ceratorhiza, but this is now considered a synonym of Rhizoctonia. Ceratobasidium species, excluding the type, are also now considered synonymous with Rhizoctonia and some species have been transferred to the latter genus. 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.

<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.

Protomerulius is a genus of fungi in the order Auriculariales. Basidiocarps are formed on dead wood and have an effused, smooth, spiny, or poroid hymenium. The genus is cosmopolitan.

<i>Basidiodendron</i> Genus of fungi

Basidiodendron is a genus of fungi in the order Auriculariales. Basidiocarps are corticioid, thin, effused and are typically found on fallen wood. The genus is widespread in both temperate and tropical regions and contains over 30 species.

Elmerina is a genus of fungi in the order Auriculariales. Basidiocarps are formed on dead wood and are either bracket-like with a poroid hymenium or densely clavarioid. Species are known from East Asia and Australia.

<i>Myxarium</i> Genus of fungi

Proterochaete is a genus of fungi in the family Auriculariaceae. The type and only species, Proterochaete adusta, produces thin, effused, corticioid basidiocarps with a smooth or spiny surface on wood. The species was originally described from North America and is also known from northern Europe and Asia.

<i>Tulasnella violea</i> Species of fungus

Tulasnella violea is a species of fungus in the order Cantharellales. Basidiocarps are typically smooth, ceraceous (waxy), violet-pink or lilaceous to grey, and occur on the underside of fallen branches and logs. It is one of the more conspicuous Tulasnella species and appears to be distributed worldwide. Though normally saprotrophic, Tulasnella violea can form a mycorrhizal association with orchids.

Patouillardina is a genus of fungi in the order Auriculariales. The type and only species, P. cinerea, forms waxy, effused, corticioid basidiocarps with basidia that are diagonally septate. The species is presumed to be saprotrophic, growing on dead wood. It was originally described from Brazil, but appears to be pantropical, having also been recorded from Brunei, Cambodia, Cameroon, Cuba, Guatemala, Mexico, Panama, and Tahiti.

Platygloea is a genus of fungi belonging to the class Pucciniomycetes. Basidiocarps of the type species are disc-shaped, gelatinous, and occur on dead wood, probably as a saprotroph. Microscopically, all species of Platygloea sensu lato have auricularioid basidia. Currently the genus contains a heterogeneous mix of auricularioid fungi not yet accommodated in other genera.

<i>Exidia candida</i> Species of fungus

Exidia candida is a species of fungus in the family Auriculariaceae. Basidiocarps are gelatinous, whitish, and cushioned-shaped at first, becoming effused and corrugated.
