Junghuhnia nitida is a widespread species of crust fungus in the family Steccherinaceae.
Originally described as Poria nitida in 1800 by Christian Hendrik Persoon, the fungus has undergone several name changes in its taxonomic history. It was relocated to the genus Junghuhnia by Leif Ryvarden in 1972. [2]
The fungus grows on the fallen wood of deciduous trees, in which it causes a white rot. It is widely distributed, found in Asia, Africa, Europe, North America, [3] and South America. [4]
Junghuhnia nitida contains the bioactive compound nitidon, a highly oxidised pyranone derivative with antibiotic and cytotoxic activities in in vitro experiments. [5] A total synthesis of this compound was reported in 2004. [6]
The Polyporales are an order of about 1800 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 forest and amenity 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.
Junghuhnia is a genus of crust fungi in the family Steccherinaceae. It was circumscribed by Czech mycologist August Carl Joseph Corda in 1842. The generic name honours German-Dutch botanist Franz Wilhelm Junghuhn.
Polyporus is a genus of poroid fungi in the family Polyporaceae.
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.
Oxyporus is a genus of polypore fungi in the family Schizoporaceae. An individual family Oxyporaceae was described for the genus. A number of species in this genus are plant pathogens, causing a white rot. The genus is widely distributed.
Rigidoporus is a genus of fungi in the family Meripilaceae. Many of the species in this genus are plant pathogens. The widespread genus, which contains about forty species, was originally circumscribed by American mycologist William Alphonso Murrill in 1905. The generic name combines the Latin word rigidus ("rigid") with the Ancient Greek word πόρος ("pore").
The Steccherinaceae are a family of about 200 species of fungi in the order Polyporales. It includes crust-like, toothed, and poroid species that cause a white rot in dead wood.
Ceriporiopsis is a genus of fungi in the family Phanerochaetaceae. The genus is widely distributed, and, according to a 2008 estimate, contains about 25 species. Ceriporiopsis was circumscribed in 1963 by Polish mycologist Stanislaw Domanski. The genus is a wastebasket taxon, containing "species that share common macroscopic and microscopic characteristics, but are not necessarily related." Ceriporiopsis species are crust fungi that cause a white rot. They have a monomitic hyphal system, containing only generative hyphae, and these hyphae have clamp connections.
Ceriporia is a widely distributed genus of crust fungi.
Amauroderma is a genus of polypore fungi in the family Ganodermataceae. The genus, widespread in tropical areas, contains about 70 species. Amauroderma fungi are wood-decay fungi that feed and fruit on decayed branches and trunks.
Mycorrhaphium is a genus of fungi in the family Steccherinaceae. The genus was circumscribed by Dutch mycologist Rudolph Arnold Maas Geesteranus in 1962. The type species is Mycorrhaphium adustum. Fruit bodies of species in the genus have caps, stipes, and a hydnoid (tooth-like) hymenophore. There is a dimitic hyphal system, where the skeletal hyphae are found only in the tissue of the "teeth", and a lack of cystidia. The spores are smooth, hyaline (translucent), and inamyloid.
Steccherinum is a widely distributed genus of toothed crust fungi in the family Steccherinaceae.
Aurantiporus is a genus of poroid fungi in the family Meruliaceae. Circumscribed by American mycologist William Alphonso Murrill in 1905, the genus contains five species found mostly in northern temperate regions. Molecular analysis of several Aurantiporus species suggests that the genus is not monophyletic, but some other related polypore species need to be sequenced and studied before appropriate taxonomic changes can be made. In 2018, Viktor Papp and Bálint Dima proposed a new genus Odoria to contain Aurantiporus alborubescens based on multigene phylogenetic analyses. The generic name is derived from the Latin aurantius ("orange") and the Ancient Greek πόρος (pore).
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.
Grammothele is a genus of poroid crust fungi in the family Polyporaceae.
Nigroporus is a genus of poroid fungi in the family Steccherinaceae. The genus was circumscribed by American mycologist William Alphonso Murrill in 1905. Nigroporus has a pantropical distribution. The genus name combines the Latin word niger ("black") with the Ancient Greek word πόρος ("pore").
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. Skeletocutis causes a white rot in a diverse array of woody substrates. Their 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.
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."
Crustomyces subabruptus is a species of toothed crust fungus in the family Cystostereaceae.
Datroniella scutellata is a species of fungus in the family Polyporaceae, and the type species of genus Datroniella.
