Synonyms [2] | |
Fomitopsis quercina is a species of mushroom in the order Polyporales. Commonly known as the thick-walled maze polypore, [3] maze-gill fungusoak-loving maze polypore, or oak mazegill, the specific epithet refers to the oak genus Quercus , upon which it frequently grows, causing a brown rot. [4] It is found in Europe, Asia, Northern Africa and Australasia. Though inedible, it can be used as a natural comb and has been the subject of chemical research.
Having previously been in the genus Daedalea, it was transferred to the new genus Fomitopsis in 2024, based on molecular phylogenetic data. The newly proposed name is Fomitopsis quercina(L.) Spirin & Miettinen (2024). [5]
The sessile, fan-shaped fruiting bodies are typically 3–20 centimetres (1.2–7.9 in) in diameter and up to 8 centimetres (3.1 in) thick. They are found singly or in tiered groups, usually on rotting oak. The upper surface of the cap may be various shades of brown, and is sometimes zonate. The pore surface, white to tan in color, is initially porous, but as the fruit body matures, some of the pore walls break down, forming slits with blunt partitions.[ citation needed ] This results in the characteristic maze-like (daedaloid or labyrinthinine/labyrinthiform) appearance. [1] The tube walls are 10–30 mm (0.39–1.18 in) long, with thick walls. The basidiospores are 5–7 × 2–4 μm, smooth, and elliptical in shape. In deposit the spores are white.
This mushroom is inedible [6] due to its cork-like texture.
A variant has been described that has large, angular pores similar to those in the genus Trametes , named F. quercina forma trametea. [7]
Although Fomitopsis quercina prefers to grow on Quercus species, it has also been found on the tree species Fagus grandifolia , Fraxinus americana , Juglans nigra , and Ulmus americana . [8]
It has been reported from nearly all European countries, following the pattern of oak distribution. It has also been reported in Northern Africa, North America, (Tunisia), Asia from Caucasus to India, and also Australia. [9]
Fruit bodies of Fomitopsis quercina have been used as a natural comb and aphrodisiac, employed for brushing down horses with tender skin. [10] Gilbertson notes that in England, smoldering fruit bodies were used for anesthetizing bees. [11]
This species has been investigated for application in bioremediation. [12] The lignin-degrading enzyme laccase, isolated and purified from F. quercina, has shown use in biodegrading a variety of toxic dyes and pigments. [13]
The compound quercinol (a chromene derivative), isolated from the oak mazegill, has anti-inflammatory activity, and inhibits the enzymes cyclooxygenase-2, xanthine oxidase, and horseradish peroxidase. [14]
The Polyporales are an order of about 1,800 species of fungi in the division Basidiomycota. The order includes some polypores as well as many corticioid fungi and a few agarics. Many species within the order are saprotrophic, most of them wood-rotters. Some genera, such as Ganoderma and Fomes, contain species that attack living tissues and then continue to degrade the wood of their dead hosts. Those of economic importance include several important pathogens of trees and a few species that cause damage by rotting structural timber. Some of the Polyporales are commercially cultivated and marketed for use as food items or in traditional Chinese medicine.
Polypores are a group of fungi that form large fruiting bodies with pores or tubes on the underside. They are a morphological group of basidiomycetes-like gilled mushrooms and hydnoid fungi, and not all polypores are closely related to each other. Polypores are also called bracket fungi or shelf fungi, and they characteristically produce woody, shelf- or bracket-shaped or occasionally circular fruiting bodies that are called conks. Over one thousand polypore species have been described to science, but a large part of the diversity is still unknown even in relatively well-studied temperate areas.
Fomitopsis betulina, commonly known as the birch polypore, birch bracket, or razor strop, is a common bracket fungus and, as the name suggests, grows almost exclusively on birch trees. The brackets burst out from the bark of the tree, and these fruit bodies can last for more than a year.
Fomitopsis pinicola, is a stem decay fungus common on softwood and hardwood trees. Its conk is known as the red-belted conk. The species is common throughout temperate Europe and Asia. It is a decay fungus that serves as a small-scale disturbance agent in coastal rainforest ecosystems. It influences stand structure and succession in temperate rainforests. It performs essential nutrient cycling functions in forests. As well as a key producer of brown rot residues that are stable soil components in coniferous forest ecosystems. It has been reported that mushrooms have significant antioxidant activity.
Laricifomes officinalis, also known as agarikon, eburiko, or the quinine conk, is a wood-decay fungus that causes brown heart rot on conifers native to Europe, Asia, and North America, as well as Morocco. This fungus is the only member of the genus Laricifomes, in the order Polyporales. The fruiting bodies grow in large conks on the trunks of trees.
Gloeophyllum sepiarium, the rusty gilled polypore, is a wood decay fungus that causes a brown rot.
Bjerkandera adusta, commonly known as the smoky polypore or smoky bracket, is a species of fungus in the family Meruliaceae. It is a plant pathogen that causes white rot in live trees, but most commonly appears on dead wood. It was first described scientifically as Boletus adustus by Carl Ludwig Willdenow in 1787. The genome sequence of Bjerkandera adusta was reported in 2013. The species is inedible.
Cerrena unicolor, commonly known as the mossy maze polypore, is a species of poroid fungus in the genus Cerrena. This saprobic fungus causes white rot.
Daedaleopsis confragosa, commonly known as the thin walled maze polypore or the blushing bracket, is a species of polypore fungus in the family Polyporaceae. A plant pathogen, it causes a white rot of injured hardwoods, especially willows. The fruit bodies are semicircular and tough, have a concentrically zoned brownish upper surface, and measure up to 20 cm (8 in) in diameter. The whitish underside turns gray-brown as the fruit body ages, but bruises pink or red. It is found all year and is common in northern temperate woodlands of eastern North America, Europe, and Asia. The species was first described from Europe in 1791 as a form of Boletus, and has undergone several changes of genus in its taxonomic history. It acquired its current name when Joseph Schröter transferred it to Daedaleopsis in 1888.
Trametes elegans, also known as Lenzites elegans and Daedalea elegans, is a common polypore and wood-decay fungus with a pantropical distribution found on hardwood hosts in regions including Australia, New Zealand, and Japan. It has recently been suggested to be a complex of three different species: T. elegans,T. aesculi, and T. repanda.
Meripilus giganteus is a polypore fungus in the family Meripilaceae. It causes a white rot in various types of broadleaved trees, particularly beech (Fagus), but also Abies, Picea, Pinus, Quercus and Ulmus species. This bracket fungus, commonly known as the giant polypore or black-staining polypore, is often found in large clumps at the base of trees, although fruiting bodies are sometimes found some distance away from the trunk, parasitizing the roots. M. giganteus has a circumboreal distribution in the northern Hemisphere, and is widely distributed in Europe. In the field, it is recognizable by the large, multi-capped fruiting body, as well as its pore surface that quickly darkens black when bruised or injured.
Fomitopsis is a genus of more than 40 species of bracket fungi in the family Fomitopsidaceae.
Panus conchatus, commonly known as the lilac oysterling, smooth panus, or conch panus, is an inedible species of mushroom that occurs throughout the Northern Hemisphere. Its fruitbodies are characterized by a smooth, lilac- or tan-colored cap, and decurrent gills. The fungus is saprophytic and fruits on the decomposing wood of a wide variety of deciduous and coniferous trees. Despite being a gilled species, phylogenetic analysis has shown it is closely related to the pored species found in the family Polyporaceae.
Skeletocutis is a genus of about 40 species of poroid fungi in the family Polyporaceae. The genus has a cosmopolitan distribution, although most species are found in the Northern Hemisphere. It causes a white rot in a diverse array of woody substrates, and the fruit bodies grow as a crust on the surface of the decaying wood. Sometimes the edges of the crust are turned outward to form rudimentary bracket-like caps.
Lenzites warnieri is a species of fungus in the family Polyporaceae found in parts of Europe, Asia, and northern Africa. The species is a white rot pathogen on living wood. Its corky fruiting bodies in the shape of semicircular plates form on the trunks of several types of deciduous trees growing near water bodies in regions of moist sub-Mediterranean climate. The fruiting body, which has a lamellar fruit layer, produces spores only once.
Rhodofomitopsis lilacinogilva is a species of bracket fungus in the family Fomitopsidaceae. Known primarily from Australia, it has also been recorded from Brazil and India. It is a white-rot fungus that grows on rotting eucalyptus wood. Its main identifying feature is the lilac colour of the pore surface on the underside of the fruit body.
Quercinol, isolated from the mushroom Fomitopsis quercina, has in vitro anti-inflammatory activity, and inhibits the enzymes cyclooxygenase-2, xanthine oxidase, and horseradish peroxidase.
Bondarzewia berkeleyi, commonly known as Berkeley's polypore, or stump blossoms, is a species of polypore fungus in the family Russulaceae. It is a parasitic species that causes butt rot in oaks and other hardwood trees. A widespread fungus, it is found in the Old World and North America.
Fomitopsis ochracea is a polypore fungus found in North America. It was isolated from Albertan forests, and can be found in British Columbia. It has been isolated as far East as Newfoundland, but prefers Northern climates. It can be isolated throughout the Appalachian range, as far down as Georgia. It is a detritivore on both hardwood trees and conifers, causing a brown cubical rot. It is a member of the genus Fomitopsis, a common group of perennial fungi.
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.
