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.
Perenniporia is a cosmopolitan genus of bracket-forming or crust-like polypores in the family Polyporaceae. They are dimitic or trimitic with smooth, thick-walled basidiospores and cause a white rot in affected wood.
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 Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. As of April 2018, Index Fungorum accepts 645 species in the family.
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.
Daedalea is a genus of fungi in the family Fomitopsidaceae. The genus was circumscribed in 1801 by mycologist Christian Hendrik Persoon, based on the type D. quercina and four other species. The generic name is derived from the Ancient Greek δαιδαλεος.
Postia is a genus of brown rot fungi in the family Fomitopsidaceae.
Ceriporia is a widely distributed genus of crust fungi.
Antrodiella is a genus of fungi in the family Steccherinaceae of the order Polyporales.
Flaviporus is a genus of poroid fungi in the family Steccherinaceae.
Loweomyces is a genus of six species of poroid fungi in the family Steccherinaceae.
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).
Grammothele is a genus of poroid crust fungi in the family Polyporaceae.
Megasporoporia is a genus of four species of crust fungi in the family Polyporaceae. The genus is characterized by its large spores, and dextrinoid skeletal hyphae.
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. 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.
Amyloporia is a genus of five species of crust fungi in the family Polyporaceae. Its main distinguishing characteristic is the amyloid reaction of the skeletal hyphae, although some authors do not consider this to be sufficient to distinguish Amyloporia from the related genus Antrodia.
Funalia is a fungal genus in the family Polyporaceae. The genus was circumscribed by French mycologist Narcisse Théophile Patouillard in 1900. He made Funalia mons-veneris the type species; this fungus was originally described as Polyporus mons-veneris by Franz Wilhelm Junghuhn in 1838. The generic name is derived from the Latin funalis.
