Entoloma formosum is an inconspicuous yellowish-brown mushroom in the family Entolomataceae which are distinguished by their pink angular (or similar) spores. [1]

Description

Many Entoloma species are known to be quite difficult to identify, often requiring microscopic analysis or even DNA sequencing. E. formosum has a depressed brownish cap ranging 10–50 mm (0.4–2.0 in) in width with sometimes fine fibrillose hairs radially arranged. The stem is up to 100 mm (4 in) in height, and is buff with a darker gradient starting from the bottom. The gills are whitish when young, and become pinkish as the spores begin to color them. There is an almost exact look alike, named E. xanthocroum. It can be distinguished from E. formosum by its discolored gill edges and slightly larger spores. [2]

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

The Pluteaceae are a family of small to medium-sized mushrooms which have free gill attachment and pink spores. Members of Pluteaceae can be mistaken for members of Entolomataceae, but can be distinguished by the angled spores and attached gills of the Entolomataceae. The four genera in the Pluteaceae comprise the widely distributed Volvariella and Pluteus, the rare Chamaeota, and Volvopluteus, which was newly described in 2011 as a result of molecular analysis. The Dictionary of the Fungi estimates there are 364 species in the family.

<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>Rhodocybe</i> Genus of fungi

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.

<i>Entoloma hochstetteri</i> Species of fungus

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.

<i>Entoloma rodwayi</i> Species of fungus

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.

<i>Entoloma austroprunicolor</i> Species of fungus

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.

<i>Entoloma bloxamii</i> Species of fungus

Entoloma bloxamii, commonly known as the midnight blue entoloma, or big blue pinkgill, is a species of agaric in the family Entolomataceae. 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.

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

<i>Entoloma murrayi</i> Species of fungus

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 decastes is a species of mushroom in the family Entolomataceae. Found in Italy, it was described as a new species in 2009. The fungus fruits in dense clusters in sandy soil, in coastal grassland. Fruitbodies have thin, dark brown caps measuring 1–5 cm (0.4–2.0 in) in diameter. The thick gills are crowded close together, and initially greyish before turning pinkish brown. Spores measure 11–14 by 9–12 μm.

<i>Entoloma holoconiotum</i> Species of fungus

<i>Rhodophana</i> Genus of fungi

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>Entoloma porphyrophaeum</i> Species of fungus
