Neofavolus is a genus of four species of polypore fungi in the family Polyporaceae. All four known species of Neofavolus are known from temperate regions and unknown from the tropics. Neofavolus alveolaris , the type species, is widely distributed in the temperate areas of the Northern Hemisphere, while N. cremeoalbidus and N. mikawai are known only from limited areas of eastern Asia. [1] The most recent addition to the genus (transferred from Lentinus ), N. suavissimus , is found in North America, Europe, and Japan. [2]

Description

The fruit bodies of Neofavolus species are annual, and have a cylindrical stipe that is usually laterally situated. Their caps are kidney-shaped to semicircular, circular in centrally stipitate specimens. The cap surface is either covered with flatted scales or is smooth, azonate, white to cream or brownish. The context, which is up to 1 cm thick, ranges from fleshy-tough to leathery when fresh, to brittle or corky to leathery in dried specimens. Pores on the underside of the cap vary in size, but are typically diamond shaped and may be elongated radially. [1] N. suavissimus is the single Neofavolus fungus with a hymenium featuring gills rather than pores. [2]

Neofavolus has a dimitic hyphal system, with both generative and the more predominant skeletal-binding hyphae. The generative hyphae have clamp connections. Skeletal-binding hyphae are arboriform, and hyaline. The cap cuticle comprises a cutis made of hyaline to brown agglutinated and parallel generative hyphae. These are distinct from the contextual hyphae, which largely comprise non-agglutinated skeletal-binding hyphae. The basidia are club-shaped, with four sterigmata. Spores of Neofavolus fungi are cylindrical, thin-walled, smooth, hyaline, and non-amyloid. [1]

A hypha is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium.

<i>Neolentinus</i> Genus of fungi

Neolentinus is a genus of wood-decaying agarics with tough fruit bodies composed of dimitic tissue, serrated lamella edges, and nonamyloid white binucleate basidiospores among other features. It was segregated from Lentinus in the broad taxonomic sense, hence the derivation of the name. Biologically Neolentinus species produce a brown rot type of decay of wood, whereas Lentinus causes a white rot. Molecular phylogenetic analysis shows that the two genera are unrelated. Neolentinus is phylogenetically allied to other brown rot genera such as Gloeophyllum, Heliocybe, and Veluticeps. A new order, the Gloeophyllales, has been described for these fungi. Heliocybe had been placed in synonymy but it differs phylogenetically and anatomically by the lack of clamp connections that all Neolentinus produce on their generative hyphae.

<span class="mw-page-title-main">Polyporaceae</span> Family of fungi

The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft to very tough. Most members of this family have their hymenium in vertical pores on the underside of the caps, but some of them have gills or gill-like structures. Many species are brackets, but others have a definite stipe – for example, Polyporus badius.

<i>Daedaleopsis confragosa</i> Species of fungus

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.

Abundisporus is a small genus of poroid fungi currently with seven recognized species. They differ from other polypores in having coloured rather than hyaline spores.

<i>Buglossoporus</i> Genus of fungi

Buglossoporus is a genus of fungi in the family Fomitopsidaceae. The genus was circumscribed in 1966 by Czech mycologists František Kotlába and Zdeněk Pouzar, with Buglossoporus quercinus as the type species. In some works, Buglossoporus has been treated as a synonym of Piptoporus.

<i>Panus conchatus</i> Species of fungus

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.

Antrodiella is a genus of fungi in the family Steccherinaceae of the order Polyporales.

<i>Datronia</i> Genus of fungi

Datronia is a genus of poroid crust fungi in the family Polyporaceae. The genus was circumscribed by Marinus Anton Donk in 1966, with Datronia mollis as the type species. Datronia fungi cause a white rot in hardwoods. Datronia contains six species found in northern temperate areas. The most recent addition, Datronia ustulatiligna, was described in 2015 from Himachal Pradesh in India.

<i>Favolus</i> Genus of fungi

Favolus, or honeycomb fungus, is a genus of fungi in the family Polyporaceae. The fruit bodies of Favolus species are fleshy with radially arranged pores on the underside of the cap that are angular and deeply pitted, somewhat resembling a honeycomb.

<i>Pachykytospora</i> Genus of fungi

Pachykytospora is a small genus of poroid fungi in the family Polyporaceae. Species in the cosmopolitan genus cause white rot. There are about 10 species in the genus, with newest member described from European Russia in 2007. Pachykytospora species have fruit bodies that are resupinate, with light brown tubes. They are characterized by their uneven, ellipsoid spores, and the Polyporus-like skeletal-binding hyphae.

<i>Skeletocutis</i> Genus of fungi

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.

<i>Tyromyces</i> Genus of fungi

Tyromyces is a genus of poroid fungi in the family Polyporaceae. It was circumscribed by mycologist Petter Karsten in 1881. The type species is the widely distributed Tyromyces chioneus, commonly known as the white cheese polypore. The phylogenetic position of Tyromyces within the Polyporales is uncertain, but it appears that it does not belong to the "core polyporoid clade". Tyromyces is polyphyletic as it is currently circumscribed, and has been described as "a dumping place for monomitic white-rot species with thin-walled spores."

<i>Phellinus ellipsoideus</i> Species of fungus in the family Hymenochaetaceae found in China

Phellinus ellipsoideus is a species of polypore fungus in the family Hymenochaetaceae, a specimen of which produced the largest fungal fruit body ever recorded. Found in China, the fruit bodies produced by the species are brown, woody basidiocarps that grow on dead wood, where the fungus feeds as a saprotroph. The basidiocarps are perennial, allowing them to grow very large under favourable circumstances. They are resupinate, measuring 30 centimetres (12 in) or more in length, though typically extending less than a centimetre from the surface of the wood. P. ellipsoideus produces distinct ellipsoidal spores, after which it is named, and unusual setae. These two features allow it to be readily differentiated microscopically from other, similar species. Chemical compounds isolated from the species include several steroidal compounds. These may have pharmacological applications, but further research is needed.

<i>Lenzites warnieri</i> Species of fungus

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.

<i>Pholiota nubigena</i> Species of fungus

Pholiota nubigena, commonly known as the gastroid pholiota or the bubble gum fungus, is a species of secotioid fungus in the family Strophariaceae. It is found in mountainous areas of the western United States, where it grows on rotting conifer wood, often fir logs. It fruits in spring, often under snow, and early summer toward the end of the snowmelt period in high mountain forests. Fruit bodies appear similar to unopened mushrooms, measuring 1–4 centimetres tall with 1–2.4 cm diameter caps that are whitish to brownish. They have a short but distinct whitish stipe that extend through the internal spore mass (gleba) of the fruit body into the cap. The gleba consists of irregular chambers made of contorted gills that are brownish in color. A whitish, cottony partial veil is present in young specimens, but it often disappears in age and does not leave a ring on the stipe.

<i>Loweomyces fractipes</i> Species of fungus

Loweomyces fractipes is a species of poroid fungus in the family Steccherinaceae, and the type species of the genus Loweomyces. It is a widely distributed species, found in North America, Europe, Central America, South America, and Korea.

Neodatronia is a genus of two species of poroid crust fungi in the family Polyporaceae. It was circumscribed in 2014 by Chinese mycologists Bao-Kai Cui, Hai-Jiao Li, and Yu-Cheng Dai as a segregate genus from Datronia. Neodatronia fungi differ microscopically from Datronia by having moderately to frequently branched skeleto-binding hyphae in the context, and by their somewhat smaller spores.
