Agaricus xanthodermus, commonly known as the yellow-staining agaricus, yellow-staining mushroom or yellow-stainer, is a mushroom of the genus Agaricus, which displays a strong yellow colouration at the base of the stem when cut. It has a phenolic smell. It is poisonous for most people, causing gastrointestinal upset, but can be eaten by some without apparent negative effect.
Agaricus is a genus of mushroom-forming fungi containing both edible and poisonous species, with over 400 members worldwide and possibly again as many disputed or newly-discovered species. The genus includes the common ("button") mushroom and the field mushroom, the dominant cultivated mushrooms of the West.
In mycology, a partial veil is a temporary structure of tissue found on the fruiting bodies of some basidiomycete fungi, typically agarics. Its role is to isolate and protect the developing spore-producing surface, represented by gills or tubes, found on the lower surface of the cap. A partial veil, in contrast to a universal veil, extends from the stem surface to the cap edge. The partial veil later disintegrates, once the fruiting body has matured and the spores are ready for dispersal. It might then give rise to a stem ring, or fragments attached to the stem or cap edge. In some mushrooms, both a partial veil and a universal veil may be present.
Agaricus moelleri, commonly known as the flat-top agaricus, inky mushroom, or dark scaled mushroom, is a large mushroom of the genus Agaricus. It appears occasionally in most kinds of woodland, during late summer, in northern temperate zones.
Agaricus campestris is a widely eaten gilled mushroom closely related to the cultivated A. bisporus. A. campestris is commonly known as the field mushroom or, in North America, meadow mushroom.
Agaricus augustus, known commonly as the prince, is a basidiomycete fungus of the genus Agaricus.
Agaricus bitorquis, commonly known as torq, banded agaric, spring agaric, banded agaricus, urban agaricus, or pavement mushroom, is an edible white mushroom of the genus Agaricus, similar to the common button mushroom that is sold commercially. The name supersedes Agaricus rodmani.
Panaeolus foenisecii, commonly called the mower's mushroom, haymaker, haymaker's panaeolus, or brown hay mushroom, is a very common and widely distributed little brown mushroom often found on lawns and is not an edible mushroom. In 1963 Tyler and Smith found that this mushroom contains serotonin, 5-HTP and 5-hydroxyindoleacetic acid. In many field guides it is listed as psychoactive; however, the mushroom does not produce any hallucinogenic effects.
Clitocybe nebularis or Lepista nebularis, commonly known as the clouded agaric, cloudy clitocybe, or cloud funnel, is an abundant gilled fungus which appears both in conifer-dominated forests and broad-leaved woodland in Europe and North America. Appearing in Britain from mid to late autumn, it is edible, but may cause gastrointestinal issues.
Agaricus bernardii, commonly called the salt-loving agaricus, or salt-loving mushroom, is an agaric fungus in the family Agaricaceae. The mushroom's thick stem is usually shorter than the diameter of the cap, which ranges from 5–15 centimetres and is convex to flattened. The cap surface is whitish to buff, and can develop scales or warts in age. The gills are initially pink before turning brown when the spores mature. The flesh turns reddish when it is cut or bruised. It resembles species such as A. bitorquis.
Agaricus abruptibulbus is a species of mushroom in the genus Agaricus. It is commonly known as the abruptly-bulbous agaricus or the flat-bulb mushroom. First described by the mycologist Charles Horton Peck, this bulbous-stemmed edible species smells slightly of anise or bitter almond, and turns yellow when bruised or cut. The mushroom is medium-sized, with a white, yellow-staining cap on a slender stipe that has a wide, flat bulb on the base.
Agaricus semotus is a woodland mushroom of the fungus order Agaricales. Like many of its relatives, it can be found spread throughout wooded, moist areas in the southern United States, and has been found in areas ranging from California to Florida. It is also indigenous to Great Britain and Europe. A. semotus has also been collected in New Zealand. Although various authors disagree about its edibility, its modest size prevents it from being a significant source of nutrition.
Agaricus placomyces is a toxic basidiomycete fungus of the genus Agaricus. It is found in North America; the Eurasian populations formerly known by the same scientific name are nowadays known as A. moelleri, while the present species may also be referred to as A. praeclaresquamosus.
Agaricus albolutescens, commonly known as the amber-staining agaricus, is a moderate-sized, stocky-statured mushroom with a pleasant odor; it bruises slowly but persistently yellow.
Lactarius rufulus, commonly known as the rufous candy cap, is a species of fungus in the family Russulaceae. The fruit bodies have fleshy brownish-red caps up to 10 cm (3.9 in) wide, and closely spaced pinkish-yellow gills. The stem is up to 12 cm (4.7 in) long and 3 cm (1.2 in) thick and colored similarly to the cap. The species, known only from California, Arizona, and Mexico, grows on the ground in leaf litter near oak trees. The fruit bodies resembles those of L. rufus, but L. rufulus tends to grow in clusters at a common base, rather than solitarily or in groups. A distinguishing microscopic characteristic is the near absence of large, spherical cells called sphaerocysts that are otherwise common in Lactarius species. Lactarius rufulus mushrooms are edible, and have an odor resembling maple syrup. They have been used to flavor confections and desserts.
Agaricus californicus, commonly known as the mock meadow mushroom, or California agaricus, is a poisonous mushroom in the section Xanthodermati of the genus Agaricus.
Cortinarius traganus, also known as the gassy webcap or lilac conifer cortinarius, is a basidiomycete mushroom of the genus Cortinarius. The mushrooms are characterized by their lilac color, the rusty-brown gills and spores, and rusty-brown flesh in the stem.
Agaricus cupreobrunneus, commonly known as the brown field mushroom, is an edible mushroom of the genus Agaricus.
Cortinarius sanguineus, commonly known as the blood red webcap or blood red cortinarius, is a species of fungus in the genus Cortinarius.
Tubaria furfuracea, commonly known as the scurfy twiglet or totally tedious tubaria, is a common species of agaric fungus in the family Tubariaceae. It was first described by Christiaan Hendrik Persoon in 1801 as a species of Agaricus. French mycologist Claude-Casimir Gillet transferred it to the genus Tubaria in 1876.
