Russula foetens, commonly known as the stinking russula, is a common Russula mushroom found in deciduous and coniferous forests.
The cap is hemispherical and very slimy when young, soon convex, honey yellow to ochre brown and up to 10 cm (4 in) in diameter. The gills and spores are pale cream. The strong stem is white or blotchy yellowish brown. The flesh has a strong acrid smell, when old has a fishy smell and bad taste.
Stinking russula is widely considered inedible. In countries like Russia it is used for traditional mushroom pickles after being soaked in water for several days to remove the strong taste, as also all other Russula species. [1] Such preservation method allows to use many otherwise inedible russulas and milk-caps for well digestible and savoury pickles, which are considered delicacy in Eastern Europe and Scandinavia.
Mushroom hunting, mushrooming, mushroom picking, mushroom foraging, and similar terms describe the activity of gathering mushrooms in the wild. This is typically done for culinary use, although medicinal and psychotropic uses are also known. This practice is popular throughout most of Europe, Australia, Asia, as well as in the temperate regions of Canada and the United States.
Russula is a very large genus composed of around 750 worldwide species of ectomycorrhizal mushrooms. They are typically common, fairly large, and brightly colored – making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include usually brightly coloured caps, a white to dark yellow spore print, brittle, attached gills, an absence of latex, and absence of partial veil or volva tissue on the stem. Microscopically, the genus is characterised by the amyloid ornamented spores and flesh (trama) composed of spherocysts. Members of the related genus Lactarius have similar characteristics but emit a milky latex when their gills are broken. The genus was described by Christian Hendrik Persoon in 1796.
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 shrimp russula, crab brittlegill, or 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.
Russula virescens is a basidiomycete mushroom of the genus Russula, and is commonly known as the green-cracking russula, the quilted green russula, or the green brittlegill. It can be recognized by its distinctive pale green cap that measures up to 15 cm (6 in) in diameter, the surface of which is covered with darker green angular patches. It has crowded white gills, and a firm, white stipe that is up to 8 cm (3 in) tall and 4 cm (1.6 in) thick. Considered to be one of the best edible mushrooms of the genus Russula, it is especially popular in Spain and China. With a taste that is described variously as mild, nutty, fruity, or sweet, it is cooked by grilling, frying, sautéeing, or eaten raw. Mushrooms are rich in carbohydrates and proteins, with a low fat content.
Lactarius turpis is commonly known as the ugly milk-cap in English. It is found naturally in Europe and Siberia, and has been introduced to Australia and New Zealand. While especially associated with birch, it is also found with spruce, pine and other trees in mixed woodland.
Russula nigricans, commonly known as the blackening brittlegill or blackening russula, is a gilled mushroom found in woodland in Europe. It gains both its common and scientific name from its propensity to turn black from cutting or bruising.
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 or rosey russula, 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.
Lactifluus piperatus, commonly known as the blancaccio, is a semi-edible basidiomycete fungus of the genus Lactifluus. Despite being edible, it is not recommended by some because of its poor taste, though can be used as seasoning when dried. The fruiting body is a creamy-white mushroom which is funnel-shaped when mature, with exceptionally crowded gills. It bleeds a whitish peppery-tasting milk when cut. Widely distributed across Europe and eastern North America, Lactifluus piperatus has been accidentally introduced to Australia. Mycorrhizal, it forms a symbiotic relationship with various species of deciduous tree, including beech, and hazel, and fruiting bodies are found on the forest floor in deciduous woodland.
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.
Tricholoma ustaloides is a species of mushroom in the large genus Tricholoma. It has a widespread distribution in Europe, where it is typically found in association with oak and beech trees. Although generally considered inedible, it is consumed by some in Mexico.
The mushroom Russula fellea goes by the common name of the geranium-scented russula, or bitter russula and is a member of the genus Russula, all of which are commonly known as brittlegills. It is straw or honey coloured and in Britain grows in beech woods during autumn. It is inedible.
Russula fragilis, commonly known as the fragile russula, or fragile brittlegill, is a species of mushroom 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.
Lactarius affinis, commonly known as the kindred milk cap, is a species of milk-cap mushroom in the family Russulaceae. It is found northeastern North America, where it fruits in the summer and fall, and is common in the Great Lakes region. Its fruit bodies have medium to large, slimy dull yellow or brownish caps. Although not considered poisonous, it is unpalatable because of its highly acrid taste.
Russula rosea, known as the rosy russula, is a north temperate, commonly found mushroom of the large "brittlegill" genus Russula.
Russula lutea is a common, edible species of mushroom in the genus Russula found throughout the Americas and Europe under broad-leaved trees from summer to early autumn.
Russula vinosa, commonly known in English as the darkening brittlegill, is a species of basidiomycete mushroom found in coniferous woodlands in Europe and North America in summer and early autumn. Unlike many red-capped members of the russula genus, it is edible and mild-tasting. It is usually understood to have a symbiotic relationship with evergreen tree roots, except for in mountainous areas where it has occasionally associated with birches.
Russula amoenolens, also known by its common name camembert brittlegill, is a member of the genus Russula. The species has a greyish-brown cap, with clear scoring along the edge. While inedible, the mushroom is known for its distinctive smell like camembert cheese. The mushroom often appears under oak trees from summer to autumn.
