Rhodocybe is a genus of fungi in the family Entolomataceae. Basidiocarps (fruit bodies) are agaricoid (gilled mushrooms) producing pink basidiospores that are unevenly roughened or pustular under the microscope. Species are saprotrophic and mostly grow on the ground, occasionally on wood. The genus is distributed worldwide.

Taxonomy

The genus was originally described in 1926 by French mycologist René Maire to accommodate agarics with pink spores that were roughened but not angular (as in the genus Entoloma ). In 2009, as a result of molecular research, based on cladistic analysis of DNA sequences, CoDavid et al. found that Clitopilus species form a clade nested within Rhodocybe species and proposed that these genera should be merged so that the new combined genus (called Clitopilus since it is the earlier name) would be monophyletic (a natural group). [1] Additional research, however, showed that the core groupings of Clitopilus and Rhodocybe were both monophyletic, if outlying species were moved to new genera ( Rhodophana , Clitocella , and Clitopilopsis ). [2] This disposition has been accepted by subsequent authors. [3] [4] [5] [6]

In this revised sense, the genus remains essentially the same except that Rhodocybe nitellina and associated species are now placed in Rhodophana and Rhodocybe popinalis, R. mundula, and associated species are now placed in Clitocella. [2] [3]

Description

Rhodocybe species produce agaricoid fruit bodies of various colours with a pleurotoid, collybioid, mycenoid, clitocyboid, or tricholomatoid habit. The attachment of lamellae ranges from adnexed to subdecurrent. The stipes (stems) are smooth and lack an annulus (ring). The spore print is pink. Microscopically, basidiospores have pronounced undulate-pustulate ornamentations, cystidia are mostly present, and clamp connections are absent. [2]

<span class="mw-page-title-main">Agaricales</span> Order of mushrooms

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.

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

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.

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

The Tricholomataceae are a large family of fungi within the order Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae.

<i>Entoloma</i> Genus of fungi

Entoloma is a genus of fungi in the order Agaricales. Called pinkgills in English, basidiocarps are typically agaricoid, though a minority are gasteroid. All have salmon-pink basidiospores which colour the gills at maturity and are angular (polyhedral) under a microscope. The genus is large, with almost 2000 species worldwide. Most species are saprotrophic, but some are ectomycorrhizal, and a few are parasitic on other fungi. The type, Entoloma sinuatum, is one of several Entoloma species that are poisonous, typically causing mild to severe gastrointestinal illness.

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

The Entolomataceae are a family of fungi in the order Agaricales. The family contains eight genera and 2250 species, the majority of which are in Entoloma. Basidiocarps are typically agaricoid, but a minority are cyphelloid. secotioid, or gasteroid. All produce pink basidiospores that are variously angular (polyhedral), ridged, or nodulose. Species are mostly saprotrophic, though a few are parasitic on other fungi. The family occurs worldwide.

<i>Leptonia</i> Subgenus of fungi

Leptonia is a subgenus of fungi in the genus Entoloma. Called pinkgills in English, basidiocarps are agaricoid, mostly mycenoid with slender stems. All have salmon-pink basidiospores which colour the gills at maturity and are angular (polyhedral) under a microscope. Recent DNA evidence has shown that at least 12 species belong in Leptonia in temperate Europe and Asia.

<i>Nolanea</i> Genus of fungi

Nolanea is a subgenus of fungi in the order Agaricales. Called pinkgills in English, basidiocarps are agaricoid, mostly mycenoid with slender stems. All have salmon-pink basidiospores which colour the gills at maturity and are angular (polyhedral) under a microscope. Recent DNA evidence has shown that at least 87 species belong to the subgenus Nolanea which has a worldwide distribution.

<i>Melanoleuca</i> Genus of fungi

Melanoleuca is a poorly known genus of saprotrophic mushrooms traditionally classified in the family Tricholomataceae. Most are small to medium sized, white, brown, ocher or gray with a cylindrical to subcylindrical stipe and white to pale yellowish gills. The basidiospores are ellipsoid and ornamented with amyloid warts. Melanoleuca is considered a difficult group to study due to their macroscopic similarities among species and the need of a thorough microscopic analysis to separate species. DNA studies have determined that this genus is closely related to Amanita and Pluteus and that it does not belong to the family Tricholomataceae.

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

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).

<i>Rhodotus</i> Genus of fungus

Rhodotus is a genus in the fungus family Physalacriaceae. There are two species in the genus with the best known, Rhodotus palmatus, called 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.

<i>Infundibulicybe</i> Genus of fungi

Infundibulicybe is a genus of fungi that is robustly placed incertae sedis as sister group to the Tricholomatoid clade. It has previously been part of the family of Tricholomataceae, but recent molecular phylogeny has shown it to take an isolated position within the Agaricales.

Clitopilus byssisedoides is a species of fungus in the family Entolomataceae. It was formally described as new to science in 2010, based on specimens found growing in a greenhouse in Botanischer Garten Jena, in Germany.

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

Amylocorticiales is an order of fungi in the class Agaricomycetes. The order was circumscribed in 2010 to contain mostly resupinate (crust-like) forms that have been referred to genera Anomoporia, Amyloathelia, Amylocorticiellum, Amylocorticium, Amyloxenasma, Anomoloma, Athelopsis, Ceraceomyces, Hypochniciellum, Leptosporomyces and Serpulomyces and the anomalous species, Athelia rolfsii, now classified in its own genus, Agroathelia.

<i>Rhodocybe gemina</i> Species of fungus


Rhodocybe gemina is a species of fungus in the family Entolomataceae. It has the recommended English name of tan pinkgill and produces agaricoid basidiocarps that are fleshy and cream when young, becoming brownish when mature.

<i>Aphroditeola</i> Genus of fungi

Aphroditeola is an agaric fungal monotypic genus that produces pink cantharelloid fruit bodies on coniferous forest floors. The lamellae are forked and typically the fruit bodies have a fragrant odor described as candy-like, cinnamon-like or pink bubble gum-like. It contains the one species Aphroditeola olida, which is commonly known as the pink bubblegum mushroom.

<i>Clitocella</i> Genus of fungi

Clitocella is a genus of mushroom-forming fungi in the family Entolomataceae. It was circumscribed in 2014 with Clitocella popinalis as the type species. The generic name refers to its similarities and close relationship to the genera Clitopilus and Clitopilopsis; the Latin word cella, meaning "storage place", alludes to "taxa not belonging to Clitopilus or Clitopilopsis". Species have caps with centrally placed stipes; the gills are decurrent, and crowded closely together with a smooth edge. Mushrooms produce a pink spore print. The spores have thin walls that are cyanophilic and surfaces ornamented with minute bumps that can be seen in profile and face views. This surface ornamentation distinguishes Clitocella from Clitopilus, which has longitudinally ridged spores. Clitopilopsis, in contrast, has thicker spore walls.

<i>Rhodophana</i> Genus of fungi

Rhodophana is a genus of mushroom-forming fungi in the family Entolomataceae. It originally described as a genus in 1947 by Robert Kühner, but the description was invalid until it was re-published in 1971, though as a subgenus of Rhodocybe. It did not find favour as a genus until Rhodocybe was found to be polyphyletic and Kluting et al. resurrected the name in 2014 as part of a DNA-based reclassification of the family.

<i>Botryobasidium</i> Genus of fungi

Botryobasidium is a genus of corticioid fungi belonging to the order Cantharellales. Basidiocarps are ephemeral and typically form thin, web-like, white to cream, effused patches on the underside of fallen branches, logs, and leaf litter. Several species form anamorphs producing chlamydospores. All species are wood- or litter-rotting saprotrophs and the genus has a worldwide distribution.
