Pleurotus citrinopileatus, the golden oyster mushroom (tamogitake in Japanese), is an edible gilled fungus. Native to eastern Russia, northern China, and Japan, the golden oyster mushroom is very closely related to P. cornucopiae of Europe, with some authors considering them to be at the rank of subspecies. [2] In far eastern Russia, P. citrinopileatus, they are called iI'mak, is one of the most popular wild edible mushrooms. [3]
The fruiting bodies of P. citrinopileatus grow in clusters of bright yellow to golden brown caps with a velvety, dry surface texture. Caps range from 20–65 millimetres (3⁄4–2+1⁄2 inches) in diameter. The flesh is thin and white, with a mild taste and without a strong smell. Stems are cylindrical, white in color, often curved or bent, and about 20–50 mm (3⁄4–2 in) long and 2–8 mm (1⁄16–5⁄16 in) in diameter. The gills are white, closely spaced, and run down the stem. The spores of the golden oyster mushroom are cylindrical or elliptical in shape, smooth, hyaline, amyloid, and measure 6-9 by 2–3.5 micrometres. [2] [3]
The golden oyster mushroom, like other species of oyster mushroom, is a wood-decay fungus. In the wild, P. citrinopileatus most commonly decays hardwoods such as elm. [2] [3] The first recorded observation of naturalized golden oysters in the United States occurred in 2012 on Mushroom Observer, perhaps a decade after the cultivation of the species began in North America, and they have been found growing on oak, elm, beech, and other hardwoods. Naturalized golden oysters have been found in many states including: Delaware, Illinois, Iowa, Maryland, Massachusetts, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin. Their vigorous range expansion is comparable to invasive species. In a 2018 population genomics study comparing naturalized wild isolates with commercial strains, two of the commercial isolates showed high similarity to all of the wild isolates, representing possible source strains of the wild populations. [4] The study also found highly similar wild isolates collected from geographically distant locations, in some cases over 800 miles (1,300 km) apart. This is strong evidence to suggest that the same cultivated strain has been re-introduced many times over in various parts of the United States, as opposed to a single introduction event and subsequent spread.
The golden oyster mushroom is also naturalized in several African countries: Cameroon, [5] Tanzania, [6] Kenya, [7] Burundi, [8] and Nigeria. [9] It also occurs in the wild in some Asian countries outside its native territory: in the Yemen, [10] , Korea, [11] and India. [12]
Golden oyster mushrooms are cultivated commercially, usually on a medium of grain, straw, or sawdust. [13] Pleurotus species are some of the most commonly cultivated mushrooms, particularly in China, due to their ease of cultivation and their ability to convert 100 g of organic refuse into 50-70 g of fresh mushrooms. [14]
Pleurotus citrinopileatus mushrooms are a source of antioxidants. [15] Extracts from P. citrinopileatus have been studied for their antihyperglycemic properties, decreasing blood sugar levels in diabetic rats. [16] They have also been studied as a source of lipid-lowering drugs; [17] P. ostreatus , a related oyster mushroom, has been found to contain the cholesterol-lowering drug lovastatin. [18]
In one study, among 11 other commonly cultivated or foraged mushroom species, Pleurotus citrinopileatus contained the second highest amount of the antioxidant and amino acid ergothioneine at 3.94mg per gram of dry weight, and fourth highest in glutathione at 1.39mg per gram of dry weight. Both compounds had their highest concentrations in the pileus tissue. It had the highest amount of ergothioneine among the other saprotrophs within the group. [19]
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.
Edible mushrooms are the fleshy fruit bodies of numerous species of macrofungi. Edibility may be defined by criteria including the absence of poisonous effects on humans and desirable taste and aroma. Mushrooms that have a particularly desirable taste are described as "choice". Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor.
Lovastatin, sold under the brand name Mevacor among others, is a statin medication, to treat high blood cholesterol and reduce the risk of cardiovascular disease. Its use is recommended together with lifestyle changes. It is taken by mouth.
Pleurotus ostreatus, the oyster mushroom, oyster fungus, hiratake, or pearl oyster mushroom is a common edible mushroom. It is one of the more commonly sought wild mushrooms, though it can also be cultivated on straw and other media.
Laetiporus sulphureus is a species of bracket fungus found in Europe and North America. Its common names are sulphur polypore, sulphur shelf, and chicken-of-the-woods. Its fruit bodies grow as striking golden-yellow shelf-like structures on tree trunks and branches. Old fruitbodies fade to pale beige or pale grey. The undersurface of the fruit body is made up of tubelike pores rather than gills.
Fungiculture is the cultivation of fungi such as mushrooms. Cultivating fungi can yield foods, medicine, construction materials and other products. A mushroom farm is involved in the business of growing fungi.
Pleurotus eryngii is an edible mushroom native to Mediterranean regions of Europe, the Middle East, and North Africa, but also grown in many parts of Asia.
Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms, P. ostreatus. Species of Pleurotus may be called oyster, abalone, or tree mushrooms, and are some of the most commonly cultivated edible mushrooms in the world. Pleurotus fungi have also been used in mycoremediation of pollutants, such as petroleum and polycyclic aromatic hydrocarbons.
Hericium erinaceus, commonly known as lion's mane mushroom, yamabushitake, bearded tooth fungus, or bearded hedgehog, is an edible mushroom belonging to the tooth fungus group. Native to North America, Europe, and Asia, it can be identified by its long spines, occurrence on hardwoods, and tendency to grow a single clump of dangling spines. The fruit bodies can be harvested for culinary use.
Omphalotus nidiformis, or ghost fungus, is a gilled basidiomycete mushroom most notable for its bioluminescent properties. It is known to be found primarily in southern Australia and Tasmania, but was reported from India in 2012 and 2018. The fan or funnel shaped fruit bodies are up to 30 cm (12 in) across, with cream-coloured caps overlain with shades of orange, brown, purple, or bluish-black. The white or cream gills run down the length of the stipe, which is up to 8 cm (3 in) long and tapers in thickness to the base. The fungus is both saprotrophic and parasitic, and its fruit bodies are generally found growing in overlapping clusters on a wide variety of dead or dying trees.
Pleurotus pulmonarius, commonly known as the Indian oyster, Italian oyster, phoenix mushroom, or the lung oyster, is a mushroom very similar to Pleurotus ostreatus, the pearl oyster, but with a few noticeable differences. The caps of pulmonarius are much paler and smaller than ostreatus and develops more of a stem. P. pulmonarius also prefers warmer weather than ostreatus and will appear later in the summer. Otherwise, the taste and cultivation of the two species is generally described as largely the same. Another similar species, North America's Pleurotus populinus, is restricted to growing on aspen and cottonwood.
Hericium is a genus of edible mushrooms in the family Hericiaceae. Species in this genus are white and fleshy and grow on dead or dying wood; fruiting bodies resemble a mass of fragile icicle-like spines that are suspended from either a branched supporting framework or from a tough, unbranched cushion of tissue. This distinctive structure has earned Hericium species a variety of common names—monkey's head, lion's mane, and bear's head are examples. Taxonomically, this genus was previously placed within the order Aphyllophorales, but recent molecular studies now place it in the Russulales.
Pleurotus nebrodensis, commonly known as funcia di basilicu "fungus of basilisk" or carduncieddu di macchia "macchia carduncieddu(?)", is a fungus that was declared by the IUCN as critically endangered in 2006. This fungus only grows on limestone in northern Sicily in association with Cachrys ferulacea. The characteristics of the mushroom are its creamy white to yellow colour, its diameter of between 5 and 20 centimeters, its extremely angled gills, and the breaking apart of the cap surface at maturity.
Pleurotus djamor, commonly known as the pink oyster mushroom, is a species of fungus in the family Pleurotaceae.

Pleurotus tuber-regium, the king tuber mushroom, is an edible gilled fungus native to the tropics, including Africa, Asia, and Australasia. It has been shown to be a distinct species incapable of cross-breeding and phylogenetically removed from other species of Pleurotus.
Omphalotus japonicus, commonly known as the tsukiyotake(月夜茸), is an orange to brown-colored gilled mushroom native to Japan and Eastern Asia. It is a member of the cosmopolitan genus Omphalotus, the members of which have bioluminescent fruit bodies which glow in darkness. A 2004 molecular study shows it to be most closely related to a clade composed of Omphalotus nidiformis of Australia, Omphalotus olivascens of Western North America and Omphalotus olearius of Europe.
Pleurotus cornucopiae is a species of edible fungus in the genus Pleurotus, It is quite similar to the better-known Pleurotus ostreatus, and like that species is cultivated and sold in markets in Europe and China, but it is distinguished because its gills are very decurrent, forming a network on the stem.
Hypsizygus ulmarius, also known as the elm oyster mushroom, and less commonly as the elm leech, elm Pleurotus, is an edible fungus. It has often been confused with oyster mushrooms in the Pleurotus genus but can be differentiated easily as the gills are either not decurrent or not deeply decurrent. While not quite as common as true oyster mushrooms, they have a wide range globally in temperate forests. The mushrooms and vegetative hyphae of this species have been studied in recent years for their potential benefits to human health, and mycoremediation.
Pleurotus cystidiosus, also known as abalone mushroom and maple oyster mushroom, is an edible species of fungus in the family Pleurotaceae, described as new to science by mycologist Orson K. Miller Jr. in 1969. It can be cultivated, with spores and growing kits being available commercially. Antromycopsis macrocarpa is the anamorphic form of this species.
