The Irpicaceae are a family of mostly polypores and crust fungi in the order Polyporales.
The family was circumscribed in 2003 by mycologists Viacheslav Spirin and Ivan Zmitrovich. The type genus is Irpex . [1] Later multi-gene phylogenetic analyses of the Polyporales supported the use of this family. In these analyses, Irpicaceae is a sister taxon to the Meruliaceae; these two families, as well as the Phanerochaetaceae, form the phlebioid clade. [2] [3]
Irpicaceae has both polypore and crust fungi. They have a monomitic hyphal system, containing only generative hyphae that do not have clamp connections. Their spores are thin-walled, smooth, and translucent. Cystidia are often absent from the hymenium. More rarely, some species are dimitic and/or with cystidia and/or clamp-connections present; for example, Emmia and Irpex have cystidia, and there are clamp connections in Gloeoporus. Irpicaceae fungi produce a white-rot, except for one brown-rot genus (Leptoporus). [3]
According to Justo and colleagues, several genera from various other Polyporales families contain species that should be in the Irpicaceae, and will need to be reclassified. These include: Candelabrochaete ( C. langloisii and C. septocystidia ), Ceraceomyces ( C. eludens , C. microsporus , and C. serpens ), Ceriporia ( C. lacerata ), Ceriporiopsis ( C. aneirina and C. resinascens ), Hapalopilus ( H. ochraceolateritius ), Phanerochaete ( P. allantospora , P. angustocystidiata , P. exilis , P. ginnsii , P. intertexta , P. leptoderma , and P. xerophila ), and Phlebia ( P. albida , P. albomellea , and P. nitidula .

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 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.
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 Phanerochaetaceae are a family of mostly crust fungi in the order Polyporales.
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.
Auriporia is a small genus of four species of poroid fungi in the family Fomitopsidaceae.
Byssomerulius is a widely distributed genus of crust fungi.
Meruliopsis is a genus of poroid crust fungi. The genus was circumscribed by Russian mycologist Appollinaris Semenovich Bondartsev in 1959.
Gloeoporus is a genus of crust fungi in the family Irpicaceae. The genus has a widespread distribution.
Ceriporia is a widely distributed genus of crust fungi.
Antrodiella is a genus of fungi in the family Steccherinaceae of the order Polyporales.
Irpex is a genus of corticioid fungi in the order Polyporales. Species produce fruit bodies that grow as a crust on the surface of dead hardwoods. The crust features an irpicioid spore-bearing surface, meaning it has irregular and flattened teeth. Irpex is distinguished from the similar genera Junghuhnia and Steccherinum by the simple septa found in the generative hyphae.
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.
Dentocorticium is a genus of six species of poroid fungi in the family Polyporaceae. The genus was revised in 2018, with several new species added and some older species transferred to other genera, based on phylogenetic analyses.
Leptoporus is a genus of polypore fungi. The type species, Leptoporus mollis, is widespread throughout north temperate areas. The generic name is derived from the Ancient Greek words λεπτός ("thin") and 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.
Hydnopolyporus is a genus of two species of fungi. The genus was circumscribed in 1962 by English mycologist Derek Reid with H. fimbriatus as the type species.
Fibroporia is a genus of ten species of poroid crust fungi in the family Fomitopsidaceae. The genus contains species similar to those in genus Antrodia, but they are phylogenetically distinct.
Byssomerulius corium is a common species of crust fungus in the family Irpicaceae. The fungus was first described as Thelephora corium by Christiaan Hendrik Persoon in 1801. Erast Parmasto made it the type species of his newly circumscribed genus Byssomerulius in 1967.
Efibula is a genus of 16 species of crust fungi in the family Irpicaceae.
