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.
Russula cyanoxantha, synonymous with R. xyanoxantha, commonly known as the charcoal burner or variegated russula, is a basidiomycete mushroom, distinguished from most other members of the genus Russula by the fact that its gills do not split, but are soft and flexible. It is one of the most common species of Russula in Europe.
Russula claroflava, commonly known as the yellow russula, yellow swamp russula or yellow swamp brittlegill, is a basidiomycete mushroom of the genus Russula. It is found in wet places under birch and aspen woodlands across Europe and North America. It has a yellow cap, white gills and stipe and bruises grey. It is mild-tasting and regarded as good to eat.
Russula brevipes is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill. It is widespread in North America, and was reported from Pakistan in 2006. The fungus grows in a mycorrhizal association with trees from several genera, including fir, spruce, Douglas-fir, and hemlock. Fruit bodies are white and large, with convex to funnel-shaped caps measuring 7–30 cm (3–12 in) wide set atop a thick stipe up to 8 cm (3 in) long. The gills on the cap underside are closely spaced and sometimes have a faint bluish tint. Spores are roughly spherical, and have a network-like surface dotted with warts.
Russula aeruginea, also known as the grass-green russula, the tacky green russula, or the green russula, is an edible Russula mushroom. Widely distributed in northern temperate regions, it is usually found under birch, mostly in pine forests. The very poisonous death cap can have a similar appearance, especially from above.
Russula atropurpurea is an edible member of the genus Russula. 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 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.
Hygrophorus subalpinus, commonly known as the subalpine waxycap, is a species of white snowbank fungus in the family Hygrophoraceae. Found in the mountains of western North America, it is found growing on the ground under conifers, usually near snowbanks.
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.
Lactarius alnicola, commonly known as the golden milkcap, is a species of fungus in the family Russulaceae. The fruit bodies produced by the fungus are characterized by a sticky, vanilla-colored cap up to 20 cm (7.9 in) wide with a mixture of yellow tones arranged in faint concentric bands. The stem is up to 5 cm (2.0 in) long and has yellow-brown spots. When it is cut or injured, the mushroom oozes a white latex, which has an intensely peppery taste. The acrid taste of the fruit bodies renders them unpalatable. The fungus is found in the western United States and Mexico, where it grows in mycorrhizal associations with various coniferous trees species, such as spruce, pine and fir, and deciduous species such as oak and alder. It has also been collected in India. Two varieties have been named: var. pitkinensis, known from Colorado, and var. pungens, from Michigan.
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.
Lactifluus deceptivus, commonly known as the deceiving milkcap, is a common species of fungus in the family Russulaceae. It is found throughout eastern North America on the ground in coniferous forests near hemlock or deciduous forests near oak, and in oak-dominated forests of Costa Rica. It produces large mushrooms with funnel-shaped caps reaching up to 25 cm (9.8 in) in diameter, on top of hard white stems that may reach 4–10 cm (1.6–3.9 in) long and up to 3 cm (1.2 in) thick. The gills are closely spaced together and yellowish-cream in color. When young, the cap is white in all parts, but the depressed center becomes dull brownish in age and breaks up into scales. The edge of the cap has a roll of cottony tissue that collapses as the cap expands. The surface of the stem—especially near the base—has a velvety texture. The mushroom "bleeds" a milky white acrid latex when it is cut or injured. Similar milk-cap species with which L. deceptivus might be confused include Lactifluus piperatus, L. pseudodeceptivus, L. caeruleitinctus, L. subvellereus, Lactarius arcuatus and Lactarius parvulus.
Russula rosea, known as the rosy russula, is a north temperate, commonly found mushroom of the large "brittlegill" genus Russula.
Russula olivacea is an edible and non-poisonous Russula mushroom found mostly in groups from June in deciduous and coniferous forests, mainly under spruce and beech; not rare.
Russula decolorans, commonly known as the graying russula, is an edible Russula mushroom found in groups in coniferous forests.
Hygrophorus purpurascens, commonly known as the purple-red waxy cap, is a species of agaric fungus in the family Hygrophoraceae. Its cap has a pink background color with streaks of purplish red overlaid, and mature gills have red spots.
Russula densifolia, commonly known as the crowded russula or the reddening russula, is a species of agaric fungus in the family Russulaceae. It was first described in 1833 and given its current name in 1876. A widespread species, it is found in Asia, Europe, and North America, where it fruits on the ground in mixed and deciduous forests. Fruit bodies (mushrooms) are robust and squat, with caps up to 14.5 cm (5.7 in) in diameter, and stems that are 2–7.5 cm (0.8–3.0 in) long by 1.2–2.5 cm (0.5–1.0 in) thick. The mushrooms are characterized by the red and then black color changes that occur in the flesh when it is bruised, and a relatively thick cap cuticle. Although the mushroom is sold as an edible species in some areas of Asia, it is mild to moderately toxic, and may cause gastrointestinal upset if consumed. Several bioactive compounds have been isolated and identified from the mushroom.
Russula crustosa, commonly known as the crusty russula, is a species of fungus in the family Russulaceae. It is found in Asia and North America.
Hygrophorus russula, commonly known as the pinkmottle woodwax, false russula, or russula-like waxy cap, is a fungus native to North America and Europe.
