Pleurotus tuber-regium, the king tuber mushroom, is an edible gilled fungus native to the tropics, including Africa, Asia, and Australasia. [1] It has been shown to be a distinct species incapable of cross-breeding and phylogenetically removed from other species of Pleurotus . [2]

Pleurotustuber-regium is a saprotroph found on dead wood, including Daniellia trees in Africa. [3] As the fungus consumes the wood, it produces a sclerotium, or storage tuber, either within the decaying wood or in the underlying soil. These sclerotia are round, dark brown with white interiors, and up to 30 cm wide. The fruiting bodies then emerge from the sclerotium. Both the sclerotium and the fruiting bodies are edible. [1]

In addition to being saprotrophic, P. tuber-regium is also nematophagous, catching nematodes by paralyzing them with a toxin. [4]

Pleurotus tuber-regium has a history of economic importance in Africa as food and as a medicinal mushroom. [1] [5] Industrial cultivation is not yet common, but studies have shown P. tuber-regium can be grown on organic wastes such as corn, sawdust, cardboard. [3] [5] [6] Mycelial growth occurs between 15 °C and 40 °C, with an optimum growth rate at 35 °C. [1] A recent study demonstrated that polysaccharides of P. tuber-regium are able to delay the progression of diabetes and associated complications in rats with insulin resistance. [7]

Pleurotus tuber-regium can degrade polyethylene film. [8]

<span class="mw-page-title-main">Edible mushroom</span> Edible fungi fruit bodies

Edible mushrooms are the fleshy fruit bodies of several 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.

<i>Pleurotus ostreatus</i> Species of fungus

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.

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.

<i>Pleurotus</i> Genus of fungi

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.

<span class="mw-page-title-main">Sclerotium</span> Mycelial mass

A sclerotium, is a compact mass of hardened fungal mycelium containing food reserves. One role of sclerotia is to survive environmental extremes. In some higher fungi such as ergot, sclerotia become detached and remain dormant until favorable growth conditions return. Sclerotia initially were mistaken for individual organisms and described as separate species until Louis René Tulasne proved in 1853 that sclerotia are only a stage in the life cycle of some fungi. Further investigation showed that this stage appears in many fungi belonging to many diverse groups. Sclerotia are important in the understanding of the life cycle and reproduction of fungi, as a food source, as medicine, and in agricultural blight management.

<i>Omphalotus nidiformis</i> Species of bioluminescent fungus in the family Marasmiaceae

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.

<i>Wynnea americana</i> Species of fungus

Wynnea americana, commonly known as moose antlers or rabbit ears, is a species of fungus in the family Sarcoscyphaceae. The uncommon species is recognizable by its spoon-shaped or rabbit ear–shaped fruit bodies that may reach up to 13 cm (5 in) tall. It has dark brown and warty outer surfaces, while the fertile spore-bearing inner surface is orange to pinkish to reddish brown. It is distinguished from other species in its genus by the pustules on the outer surface, and microscopically by the large asymmetrical longitudinally ribbed spores with a sharply pointed tip. The spores are made in structures called asci, which have thickened rings at one end that are capped by a hinged structure known as the operculum—a lid that opens to release spores from the ascus.

<i>Collybia cookei</i> Species of fungus

Collybia cookei is a species of fungus in the family Tricholomataceae, and one of three species in the genus Collybia. It is known from Europe, Asia, and North America. The fungus produces fruit bodies that usually grow on the decomposing remains of other mushrooms, like Meripilus giganteus, Inonotus hispidus, or species of Russula; occasionally fruit bodies are found on rich humus or well-decayed wood. The fungus produces small white mushrooms with caps up to 9 mm (0.35 in) in diameter, supported by thin stems that originate from a yellowish-brown sclerotium. The mushroom is difficult to distinguish from the other two species of Collybia unless an effort is made to examine the sclerotia, which is usually buried in the substrate. The edibility of the mushroom has not been determined.

<i>Pleurotus citrinopileatus</i> Species of fungus

Pleurotus citrinopileatus, the golden oyster mushroom, 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. In far eastern Russia, P. citrinopileatus, they are called iI'mak, is one of the most popular wild edible mushrooms.

<i>Morchella rufobrunnea</i> Species of edible fungus in the family Morchellaceae

Morchella rufobrunnea, commonly known as the blushing morel, is a species of ascomycete fungus in the family Morchellaceae. A choice edible species, the fungus was described as new to science in 1998 by mycologists Gastón Guzmán and Fidel Tapia from collections made in Veracruz, Mexico. Its distribution was later revealed to be far more widespread after several DNA studies suggested that it is also present in the West Coast of the United States, Israel, Australia, Cyprus, Malta and Switzerland.
