Rhodocybe gemina is a species of fungus in the family Entolomataceae. It has the recommended English name of tan pinkgill [1] and produces agaricoid basidiocarps (fruit bodies) that are fleshy and cream when young, becoming brownish when mature.
The species was originally named Hypophyllum geminum in 1793 by French mycologist Jean-Jacques Paulet and transferred to the genus Rhodocybe in 1987. [2] Prior to this, the species was commonly known as Rhodocybe truncata (Schaeff.) Singer, based on Agaricus truncatus described by Jacob Christian Schäffer in 1774. No original specimen of Schäffer's species exists, however, and the original description is so ambiguous that it has also been referred to the genus Hebeloma (as Hebeloma truncatum (Schaeff.) P. Kumm.) by some authorities. [2] Rhodocybe truncata is now considered a nomen dubium and is no longer in use. [3]
In 2009, as a result of molecular research, based on cladistic analysis of DNA sequences, CoDavid et al. included Rhodocybe gemina in their expanded concept of Clitopilus . [4] Subsequent research showed, however, that Rhodocybe is a monophyletic (natural) genus and that R. gemina belongs within it. [5]
The skin of the cap is matt, not slimy or shiny. The cap is up to 120 mm wide, at first somewhat umbonate, later becoming irregular and flattened, and brownish ochre to pinkish ochre. The gills are adnate to decurrent in attachment and the stem is whitish – often lighter than the gills and relatively short, but always lacking a veil or volva. The spore print is flesh-coloured to salmon-pink. Microscopically the spores are angular when viewed on end; when viewed from the side they are irregularly warted. [3]
A saprotrophic species, it generally grows in woodlands, both broadleaved and occasionally coniferous, but also in grassland and scrub. [3]
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.
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.
Leptonia is a genus of fungi in the order Agaricales, frequently treated as a subgenus of 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.
Nolanea is a genus of fungi in the order Agaricales, frequently treated as a subgenus of 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 87 species belong in Nolanea which has a worldwide distribution.
Rhodocybe is a genus of fungi in the family Entolomataceae. Basidiocarps are agaricoid 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.
Clitopilus prunulus, commonly known as the miller or the sweetbread mushroom, is an edible pink-spored basidiomycete mushroom found in grasslands in Europe and North America. Growing solitary to gregarious in open areas of conifer/hardwood forests; common under Bishop pine along the coast north of San Francisco; fruiting shortly after the fall rains. It has a grey to white cap and decurrent gills.
Clitopilus is a genus of fungi in the family Entolomataceae. The genus has a widespread distribution, especially in northern temperate areas. Although a 2008 estimate suggested about 30 species in the genus, a more recent publication (2009) using molecular phylogenetics has redefined the genus to include many former Rhodocybe species.
Hebeloma radicosum, commonly known as the rooting poison pie, is a species of agaric fungus in the family Hymenogastraceae. Fruit bodies (mushrooms) can be identified by the tapering root-like stipe base, as well as the almond-like odor. Found in Japan, Europe, and North America, it is an ammonia fungus, and fruits on mole, mouse, or shrew middens.
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.
Entoloma austroprunicolor is a species of agaric fungus in the family Entolomataceae. Described as new to science in 2007, it is found in Tasmania, where it fruits on the ground of wet sclerophyll forests in late spring to early winter. The fruit bodies (mushrooms) have reddish-purple caps measuring up to 5 cm (2.0 in) in diameter supported by whitish stipes measuring 3–7.5 cm (1.2–3.0 in) long by 0.2–0.6 cm (0.1–0.2 in) thick. On the cap underside, the crowded gills are initially white before turning pink as the spores mature.
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.
Tricholoma album, commonly known as the white knight, is an all-white mushroom of the large genus Tricholoma. It is found in Europe, India, and possibly North America. The cap and gills are white. The whitish stipe has no ring.
Entoloma bloxamii is a species of agaric in the family Entolomataceae. It has been given the recommended English name of big blue pinkgill. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Entoloma bloxamii has been reported from North America, but at least some of these reports represent a distinct species, Entoloma medianox. Threats to its habitat have resulted in the Big Blue Pinkgill being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.
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.
Entoloma holoconiotum is a mushroom in the family Entolomataceae. It was originally described as Nolanea holoconiota by David Largent and Harry Thiers in 1972. Machiel Noordeloos and Co-David transferred it to the genus Entoloma in 2009. The species can be found in conifer forests in western North America.
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.
Entoloma prunuloides is a species of agaric in the family Entolomataceae. It has been given the recommended English name of Mealy Pinkgill, based on its distinctive smell. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the Mealy Pinkgill being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.
Entoloma griseocyaneum is a species of agaric in the family Entolomataceae. It has been given the recommended English name of Felted Pinkgill. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the Felted Pinkgill being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.
Entoloma eugenei is a species of agaric in the family Entolomataceae. The species has a temperate distribution in the Russian Far East, Japan, and Korea, occurring mainly in mixed hardwood forests.Threats to its habitat have resulted in Entoloma eugenei being assessed as globally "endangered" on the IUCN Red List of Threatened Species.
