Russula emetica, commonly known as the sickener, emetic russula, or vomiting russula, is a basidiomycete mushroom, and the type species of the genus Russula. It has a red, convex to flat cap up to 8.5 cm (3.3 in) in diameter, with a cuticle that can be peeled off almost to the centre. The gills are white to pale cream, and closely spaced. A smooth white stem measures up to 10.5 cm (4.1 in) long and 2.4 cm (0.9 in) thick. First described in 1774, the mushroom has a wide distribution in the Northern Hemisphere, where it grows on the ground in damp woodlands in a mycorrhizal association with conifers, especially pine.
Russula xerampelina, also commonly known as the crab brittlegill or the shrimp mushroom, is a basidiomycete mushroom of the brittlegill genus Russula. Two subspecies are recognised. The fruiting bodies appear in coniferous woodlands in autumn in northern Europe and North America. Their caps are coloured various shades of wine-red, purple to green. Mild tasting and edible, it is one of the most highly regarded brittlegills for the table. It is also notable for smelling of shellfish or crab when fresh.
Formerly Russula mairei (Singer), and commonly known as the beechwood sickener, the now re-classified fungus Russula nobilis (Velen.) is a basidiomycete mushroom of the genus Russula. This group of mushrooms are noted for their brittle gills and bright colours.
Tylopilus felleus, commonly known as the bitter bolete or the bitter tylopilus, is a fungus of the bolete family. Its distribution includes east Asia, Europe, and eastern North America, extending south into Mexico and Central America. A mycorrhizal species, it grows in deciduous and coniferous woodland, often fruiting under beech and oak. Its fruit bodies have convex to flat caps that are some shade of brown, buff, or tan, and typically measure up to 15 cm (6 in) in diameter. The pore surface is initially white before turning pinkish with age. Like most boletes it lacks a ring, and it may be distinguished from Boletus edulis and other similar species by its unusual pink pores and the prominent dark brown netlike pattern on its stalk.
Caloboletus radicans, also known as the rooting bolete or whitish bolete, is a large, rare ectomycorrhizal fungus found in Europe under deciduous trees in summer and autumn. It has a pale buff or white cap, yellow pores and a stout stipe, and stains blue when bruised or cut. Bitter and inedible, it can cause severe vomiting and diarrhoea when eaten. Until 2014 it was known as Boletus radicans.
Russula sardonia, commonly known as the primrose brittlegill, is a mushroom of the genus Russula, which are commonly known as brittlegills. The fruiting body, or mushroom, is a reddish-purple, the colour of blackberry juice, and is found in coniferous woodland in summer and autumn. It is inedible, and like many inedible members of the genus, has a hot, peppery taste.
Russula sanguinaria, commonly known as the bloody brittlegill, is a strikingly coloured mushroom of the genus Russula, which has the common name of brittlegills. It is bright blood-red, inedible, and grows in association with coniferous trees. It was previously widely known as Russula sanguinea.
Russula betularum is a small, very pale member of the Russula (brittlegills) genus of mushrooms. It is usually white to very pale pink, inedible, and grows with birch trees. It is commonly known as the birch brittlegill.
Russula aurea, commonly known as the gilded brittlegill, is an uncommon species of mushroom found in deciduous woodland in Europe in summer and early autumn. Unlike many red-capped members of the genus, it is edible and mild-tasting.
Russula caerulea, commonly known as the humpback brittlegill, is a member of the genus Russula, whose members are also known as brittlegills. It is a dark vinaceous or purple-colored edible mushroom, and grows with coniferous trees in late summer and autumn. It is found in Europe and North America.
Calocybe carnea is a small pink-capped mushroom with white gills that can be found in grassy meadows, fields, or on lawns from spring to autumn in Europe and North America. Its common names include pink fairhead and pink domecap.
Russula atropurpurea is an edible member of the Russula genus, that have the common name of brittlegills. It is dark vinaceous or purple, and grows with deciduous, or occasionally coniferous trees. It is commonly called the blackish purple Russula, or the purple brittlegill.
Russula delica is a mushroom that goes by the common name of milk-white brittlegill, and is a member of the genus Russula, all of which are collectively known as brittlegills. It is mostly white, with ochraceous or brownish cap markings, and a short robust stem. It is edible, but poor in taste, and grows in coniferous, broadleaved, or mixed woods. It can be confused with other white Russula species and certain white Lactarius species.
Lactarius tabidus, commonly known as the Birch Milkcap, is an inedible mushroom of the genus Lactarius. It can be found in North America and Europe, and grows at the base of pine in Autumn. Its white milk stains fabric a sulphur yellow, from which its specific epithet derives.
Lactarius vietus is a species of fungus in the family Russulaceae, first described by Elias Magnus Fries. It produces moderately sized and brittle mushrooms, which grow on the forest floor or on rotting wood. The flattened-convex cap can vary in shape, sometimes forming the shape of a wide funnel. It is typically grey, but the colour varies. The species has crowded, light-coloured gills, which produce white milk. The spore print is typically whitish, but also varies considerably. The mushrooms typically have a strong, acrid taste and have been described as inedible, but other authors have described them as consumable after boiling. L. vietus feeds by forming an ectomycorrhizal relationship with surrounding trees, and it favours birch. It grows in autumn months and is fairly common in Europe, North America and eastern Asia.
The inedible wild mushroom Russula fragilis, which goes by the common name of the fragile brittlegill, is a member of the genus Russula, whose members are commonly known as brittlegills. It is a small, fragile, long stemmed, and variably coloured brittlegill, found in mixed forests, and woods in Europe, Asia, and North America.
The mushroom Russula gracillima, commonly known as the slender brittlegill, is a member of the Russula genus, whose members are commonly known as brittlegills. It is a small, pale, long stemmed brittlegill associated mainly with birch and is occasional in Europe, Asia, and North America.
Russula albidula is a species of mushroom in the genus Russula. The species, known in the vernacular as the boring white russula or the whitish brittlegill, is nondescript, with a small or medium dirty white fruit body, and a highly acrid taste. It is found in eastern North America.
Russula rosea, known as the rosy russula, is a north temperate, some consider it edible other inedible, commonly found mushroom of the large "brittlegill" genus Russula.
Tricholoma portentosum, commonly known as the charbonnier, or sooty head in North America, is a grey-capped edible mushroom of the large genus Tricholoma. It is found in woodlands in Europe and North America.
