Mushroom cultivation began with the Romans and Greeks, who grew the small Agrocybe aegerita. The Romans believed that fungi fruited when lightning struck. [2] In Europe, toxic forms are not normally found, but Agrocybe molesta could be confused with poisonous white Agaricus species or with poisonous Amanita species.

The edible southern species Agrocybe aegerita is commonly known as the Poplar mushroom, [3] Chestnut mushroom or Velvet pioppino (Chinese: 茶樹菇). It is a white rot fungus and is a medium-sized agaric with a convex, almost flat, cap 3 to 10 cm in diameter. Underneath, it has numerous whitish radial plates adherent to the foot, later turning to a brownish-gray color, and light elliptic spores of 8-11 by 5-7 micrometres. The white fiber foot is generally curved, having a membraneous ring on the top part which promptly turns to tobacco color due to the falling spores. [3] When very young, its color may be reddish-brown and later turn to a light brown color, more ocher toward the center and whiter around its border. It grows in tufts on logs and holes in the poplars, and other trees of large leaves [3] It is cultivated and sold in Japan, Korea, Australia and China. It is an important valuable source possessing varieties of bioactive secondary metabolites such as indole derivatives with free radical scavenging activity, cylindan with anticancer activity, and also agrocybenine with antifungal activity. [4]

Agrocybe farinacea of Japan, a species closely related to Agrocybe putaminum, [5] has been reported to contain the hallucinogen psilocybin; [6] however, there has been no recent chemical analysis carried out on this mushroom, nor any modern reports of psychoactivity.

A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. Toadstool generally denotes one poisonous to humans.

<span class="mw-page-title-main">Edible mushroom</span> Fleshy and edible fruit bodies of many species of macrofungi

Edible mushrooms are the fleshy and edible fruit bodies of several species of macrofungi. They can appear either below ground (hypogeous) or above ground (epigeous) where they may be picked by hand. Edibility may be defined by criteria that include absence of poisonous effects on humans and desirable taste and aroma. Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor.

<i>Psilocybe semilanceata</i> Species of fungus in the family Hymenogastraceae, native to Europe

Psilocybe semilanceata, commonly known as the liberty cap, is a species of fungus which produces the psychoactive compounds psilocybin, psilocin and baeocystin. It is both one of the most widely distributed psilocybin mushrooms in nature, and one of the most potent. The mushrooms have a distinctive conical to bell-shaped cap, up to 2.5 cm (1 in) in diameter, with a small nipple-like protrusion on the top. They are yellow to brown, covered with radial grooves when moist, and fade to a lighter color as they mature. Their stipes tend to be slender and long, and the same color or slightly lighter than the cap. The gill attachment to the stipe is adnexed, and they are initially cream-colored before tinting purple to black as the spores mature. The spores are dark purplish-brown in mass, ellipsoid in shape, and measure 10.5–15 by 6.5–8.5 micrometres.

<i>Galerina</i> Genus of saprobic fungi

Galerina is a genus of small brown-spore saprobic fungi, with over 300 species found throughout the world from the far north to remote Macquarie Island in the Southern Ocean. The genus is most noted for some extremely poisonous species which are occasionally confused with hallucinogenic species of Psilocybe. Species are typically small and hygrophanous, with a slender and brittle stem. They are often found growing on wood, and when on the ground have a preference for mossy habitats.

<i>Clitocybe</i> Genus of fungi

Clitocybe is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus.

<i>Entoloma sinuatum</i> Species of poisonous fungus in the family Entolomataceae found across Europe and North America

Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. The largest mushroom of the genus of pink-spored fungi known as Entoloma, it is also the type species. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands, sometimes in the form of fairy rings. Solid in shape, they resemble members of the genus Tricholoma. The ivory to light grey-brown cap is up to 20 cm (7.9 in) across with a margin that is rolled inward. The sinuate gills are pale and often yellowish, becoming pink as the spores develop. The thick whitish stem has no ring.

<i>Agaricus arvensis</i> Species of fungus

Agaricus arvensis, commonly known as the horse mushroom, is a mushroom of the genus Agaricus.

<i>Agaricus campestris</i> Species of fungus

Agaricus campestris is a widely eaten gilled mushroom closely related to the cultivated button mushroom Agaricus bisporus. It is commonly known as the field mushroom or, in North America, meadow mushroom.

<i>Pholiotina cyanopus</i> Species of fungus

Pholiotina cyanopus is a species of fungus that contains psychoactive compounds including psilocybin and the uncommon aeruginascin. Originally described as Galerula cyanopus by American mycologist George Francis Atkinson in 1918. It was transferred to Conocybe by Robert Kühner in 1935 before being transferred to Pholiotina by Rolf Singer in 1950. A 2013 molecular phylogenetics study found it to belong to a group of species currently assigned to Pholiotina that are more closely related to Galerella nigeriensis than to Pholiotina or Conocybe. It is likely that it will be moved to a different genus in the future, but this has not happened yet.

<i>Panaeolus antillarum</i> Species of fungus

Panaeolus antillarum is a species of mushroom in the family Bolbitiaceae. It is edible but not commonly eaten. It is found from northern North America through Mexico into northern South America.

<i>Clitopilus prunulus</i> Species of fungus

Clitopilus prunulus, commonly known as the miller or the sweetbread mushroom, is an edible pink-spored basidiomycete mushroom found in grasslands in Europe and North America. Growing solitary to gregarious in open areas of conifer/hardwood forests; common under Bishop pine along the coast north of San Francisco; fruiting shortly after the fall rains. It has a grey to white cap and decurrent gills.

<i>Amanita vaginata</i> Species of fungus

Amanita vaginata, commonly known as the grisette or the grisette amanita, is an edible mushroom in the fungus family Amanitaceae. Unlike many other Amanita mushrooms, A. vaginata lacks a ring on the stem. The cap is gray or brownish, 5 to 10 centimetres in diameter, and has furrows around the edge that duplicate the gill pattern underneath. It has a widespread distribution in North America, and is thought to be part of a species complex that includes other similar-looking Amanitas.

<i>Amanita daucipes</i> Species of fungus

Amanita daucipes is a species of fungus in the family Amanitaceae of the mushroom order Agaricales. Found exclusively in North America, the mushroom may be recognized in the field by the medium to large white caps with pale orange tints, and the dense covering of pale orange or reddish-brown powdery conical warts on the cap surface. The mushroom also has a characteristic large bulb at the base of its stem with a blunt short rooting base, whose shape is suggestive of the common names carrot-footed lepidella, carrot-foot amanita, or turnip-foot amanita. The mushroom has a strong odor that has been described variously as "sweet and nauseous", or compared to an old ham bone, or soap. Edibility is unknown for the species, but consumption is generally not recommended due its position in the Amanita subgroup Lepidella, which contains some poisonous members.

<i>Agrocybe pediades</i> Species of fungus

Agrocybe pediades is a typically lawn and other types of grassland mushroom, but can also grow on mulch containing horse manure. It was first described as Agaricus pediades by Swedish mycologist Elias Magnus Fries in 1821, and moved to its current genus Agrocybe by Victor Fayod in 1889. A synonym for this mushroom is Agrocybe semiorbicularis, though some guides list these separately. Technically it is edible, but it could be confused with poisonous species, including one of the genus Hebeloma.

<i>Infundibulicybe geotropa</i> Species of fungus

Infundibulicybe geotropa, also known as the trooping funnel or monk's head, is a funnel-shaped toadstool widely found in Europe and in North America. A large sturdy cream- or buff-coloured funnel-shaped mushroom, it grows in mixed woodlands, often in troops or fairy rings, one of which is over half a mile wide. Although edible, it could be confused with some poisonous species of similar colouration and size.

<i>Agrocybe praecox</i> Species of fungus

Agrocybe praecox is a species of brown-spored mushroom which appears early in the year in woods, gardens and fields. According to modern taxonomic analysis, it is just one of a cluster of closely similar species which are often referred to as the Agrocybe praecox complex. It is found in Europe, North Africa and North America.
