Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. The largest mushroom of the genus of pink-spored fungi known as Entoloma, it is also the type species. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands, sometimes in the form of fairy rings. Solid in shape, they resemble members of the genus Tricholoma. The ivory to light grey-brown cap is up to 20 cm (7.9 in) across with a margin that is rolled inward. The sinuate gills are pale and often yellowish, becoming pink as the spores develop. The thick whitish stem has no ring.
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.
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.
Entoloma hochstetteri, also known as the blue pinkgill, sky-blue mushroom or similar names, is a species of mushroom that is native to New Zealand. The small mushroom is a distinctive all-blue colour, while the gills have a slight reddish tint from the spores. The blue colouring of the fruit body is due to azulene pigments. Whether Entoloma hochstetteri is poisonous or not is unknown.
Entoloma rodwayi, known as the green stem pinkgill, is a species of fungus in the Entolomataceae family of mushrooms. A yellowish green mushroom with pink gills and spores, it is found in wet forests of Tasmania.
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.
Entoloma abortivum, commonly known as the aborted entoloma or shrimp of the woods, is an edible mushroom in the Entolomataceae family of fungi. Caution should be used in identifying the species before eating. First named Clitopilus abortivus by Miles Joseph Berkeley and Moses Ashley Curtis, it was given its current name by the Dutch mycologist Marinus Anton Donk in 1949.
Entoloma haastii is a mushroom in the Entolomataceae family. Described as new to science in 1964, it is known only from New Zealand, where it grows on the ground in leaf litter, usually near Nothofagus species.
Entoloma murrayi, commonly known as the yellow unicorn Entoloma or the unicorn pinkgill, is a species of fungus in the Entolomataceae family. First described from New England (USA) in 1859, the species is found in eastern North America, Central and South America, and southeast Asia, where it grows on the ground in wet coniferous and deciduous forests. The fungus produces yellow mushrooms that have a characteristic sharp umbo on the top of a conical cap. The mushroom is inedible and may be poisonous. Other similar species can be distinguished from E. murrayi by differences in color, morphology, or microscopic characteristics.
Entoloma mathinnae is a species of agaric fungus in the family Entolomataceae. Known only from Tasmania, Australia, it was described as new to science in 2009. Mushrooms have light yellow-brown, convex caps up to 8 cm (3.1 in) wide atop stems measuring 5–8.5 cm (2.0–3.3 in) long.
Nivatogastrium is a genus of secotioid fungi in the family Strophariaceae. The genus has contained four species found in North America and New Zealand, but the type species, Nivatogastrium nubigenum, is now considered to be a gasteroid species of Pholiota, and was transferred to that genus in 2014.
Entoloma luteum is a mushroom in the family Entolomataceae. It was described in 1902 by mycologist Charles Horton Peck. Found in North America, it fruits singly or in clusters on the ground in mixed forest. Its angular spores are non-amyloid, hyaline (translucent), and measure 9–13 by 8–12 µm. Entoloma murrayi is a lookalike species that has a more orange cap with a pointy umbo.
Egon Horak is an Austrian mycologist who has described more than 1000 species of fungi, including many from the Southern Hemisphere, particularly New Zealand and South America. He was an executive editor of the scientific journal Sydowia from 1975 to 1989, and a member of the editorial board afterwards.
Entoloma moserianum is a species of fungus in the family Entolomataceae. Found in the Netherlands where it grows on the ground in deciduous forests, it was described as new to science in 1983 by Machiel Noordeloos. The species is classified in Entoloma section Entoloma, and is similar to E. sinuatum. The fruit bodies of E. moserianum are characterized by pale colors, yellow spots on the cap, gills, and stipe, and gill edges that are partially to completely sterile. Its spores measure 9.3–11.5 by 8.1–9.3 μm The specific epithet honors Austrian mycologist Meinhard Michael Moser.
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.
Entoloma medianox is a species of agaric in the family Entolomataceae. It is known from western North America, where it was previously referred to the European species Entoloma bloxamii or E. madidum. Molecular research, based on cladistic analysis of DNA sequences, has, however, shown that Entoloma medianox is distinct.
Entoloma azureoviride is a species in the genus Entoloma. It was originally described by Egon Horak in 1982.
