Agaricus bisporus, commonly known as the cultivated mushroom, is a basidiomycete mushroom native to grasslands in Eurasia and North America. It is cultivated in more than 70 countries and is one of the most commonly and widely consumed mushrooms in the world. It has two color states while immature – white and brown – both of which have various names, with additional names for the mature state, such as chestnut, portobello, portabellini, button and champignon de Paris.
Gymnopilus luteofolius, known as the yellow-gilled gymnopilus, is a large and widely distributed mushroom that grows in dense clusters on dead hardwoods and conifers. It grows in late July to November in the east and in the winter on the west coast of North America. It has a rusty orange spore print and a bitter taste.
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.
Agaricus pattersoniae is an edible species of mushroom. It is found in the United States, where it associates with cypress trees. It has been proposed for inclusion in the IUCN Red List of Threatened Species.
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.
Hebeloma radicosum, commonly known as the rooting poison pie, is a species of agaric fungus in the family Hymenogastraceae. Fruit bodies (mushrooms) can be identified by the tapering root-like stipe base, as well as the almond-like odor.
Agaricus arorae is a moderate-sized, forest-dwelling mushroom that exhibits distinctive color changes. It fruits early in the mushroom season. Unusually within the genus Agaricus, the mushroom's cap cuticle turns yellow when exposed to a base such as potassium hydroxide or sodium hydroxide but stains red when cut. In the field, it has a brownish, fibrillose/squamulose cap, which turns red when bruised. Agaricus arorae was first described from Santa Cruz County but since has been found in San Mateo and Alameda counties. Agaricus arorae can be distinguished by its scales and a conspicuous stipe.
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.
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.
Agaricus macrosporus is a rare, edible mushroom found from June at wood fringes and in meadows.
Suillus pungens, commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus Suillus. The fruit bodies of the fungus have slimy convex caps up to 14 cm (5.5 in) wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stem (stipe) up to 7 cm (2.8 in) long, and 2 cm (0.8 in) thick. On the underside on the cap is the spore-bearing tissue consisting of minute vertically arranged tubes that appear as a surface of angular, yellowish pores. The presence of milky droplets on the pore surface of young individuals, especially in humid environments, is a characteristic feature of this species. S. pungens can usually be distinguished from other similar Suillus species by differences in distribution, odor and taste. The mushroom is considered edible, but not highly regarded.
Agaricus hondensis, commonly known as the felt-ringed agaricus, is a species of fungus in the family Agaricaceae. The species was officially described in 1912 by mycologist William Alphonso Murrill, along with three other Agaricus species that have since been placed in synonymy with A. hondensis. Found in the Pacific Northwest region of North America, A. hondensis fruits in the fall under conifers or in mixed forests.
Morchella snyderi is a species of fungus in the family Morchellaceae. Described as new to science in 2012, it occurs in the montane forests of western North America, including California, Idaho, Montana, Oregon and Washington. It produces fruit bodies up to 14 cm (5.5 in) tall with ridged and pitted conical caps, and stipes that become pitted in maturity. The color of the morel is yellow to tan when young, but the cap ridges become brown to black in maturity or when dried.
Morchella populiphila is a species of morel fungus native to northwestern North America. Described as new to science in 2012, its specific epithet refers to its association with black cottonwood. The morel used to be referred to as Morchella semilibera in western North American field guides until molecular analysis established that to be a strictly European species. M. populiphila occurs in California, Nevada and Oregon. Its fruit bodies grow up to 15 cm (6 in) tall with a ridged and pitted conical cap that attaches about halfway down the stipe. The cap ridges are dark brown to black in maturity, while the pits are yellowish to brownish. The fungus is edible, although not as highly valued as other morels.
Protostropharia semiglobata, commonly known as the dung roundhead, the halfglobe mushroom, or the hemispherical stropharia, is an agaric fungus of the family Strophariaceae. A common and widespread species with a cosmopolitan distribution, the fungus produces mushrooms on the dung of various wild and domesticated herbivores. The mushrooms have hemispherical straw yellow to buff-tan caps measuring 1–4 cm (0.4–1.6 in), greyish gills that become dark brown in age, and a slender, smooth stem 3–12 cm (1.2–4.7 in) long with a fragile ring.
Volvariella surrecta, commonly known as the piggyback rosegill, is an agaric fungus in the family Pluteaceae. Although rare, the species is widely distributed, having been reported from Asia, North America, Northern Africa, Europe, and New Zealand. The fungus grows as a parasite on the fruit bodies of other gilled mushrooms, usually Clitocybe nebularis. V. surrecta mushrooms have white or greyish silky-hairy caps up to 8 cm (3.1 in) in diameter, and white gills that turns pink in maturity. The stipe, also white, is up to 9 cm (3.5 in) long, and has a sack-like volva at its base.
Agrocybe putaminum, commonly known as the mulch fieldcap, is a species of agaric fungus in the family Strophariaceae in the Agrocybe sororia complex. Described as new to science in 1913, it is found in Asia, Australia, Europe, and western North America, where it grows in parks, gardens, and roadsides in woodchip mulch. Fruitbodies of the fungus have a dull brownish-orange cap with a matte texture, a grooved stipe, and a bitter, mealy taste.
Psilocybe allenii is a species of agaric fungus in the family Hymenogastraceae. Described as new to science in 2012, it is named after John W. Allen, who provided the type collection. It is found in the northwestern North America from British Columbia, Canada to Los Angeles, California, most commonly within 10 miles (16 km) of the Pacific coast.
Agaricus taeniatus is a species of agaric fungus. Described as new to science in 2014, it is found in northwest China, where it grows singly or in scattered groups on moss-covered soil in Picea crassifolia forests.
Stropharia caerulea, commonly known as the blue roundhead, is a species of mushroom forming fungus in the family Strophariaceae. It is a somewhat common species found in Europe and North America, where it grows as a saprophyte in meadows, roadsides, hedgerows, gardens, and woodchip mulch. S. caerulea was officially described to science in 1979, although it was known to be a distinct species for about two centuries before that. The scientific name Stropharia cyanea, as defined by Tuomikoski in 1953, and used by several later authors, is a synonym of S. caerulea.
