Hydnophlebia is a genus of five species of toothed crust fungi in the family Meruliaceae. All species are wood-decay fungi that cause a white rot.
The genus was circumscribed by Estonian mycologist Erast Parmasto in 1967. The type species, H. chrysorhiza , [1] was originally named Hydnum chrysorhizon by botanist John Torrey in 1822. [2] The genus remained monotypic until Kurt Hjortstam and Leif Ryvarden transferred H. omnivora (previously Hydnum omnivorum Shear) to the genus in 2009. [3] Three species discovered in the Canary Islands and Cape Verde archipelago were added to the genus is 2017. [4]
The fruit bodies of Hydnophlebia are reddish-orange crusts that can be peeled from the substrate. The spore-bearing area (the hymenium) comprises small cylindrical "teeth" up to 1–1.5 mm long. The hyphal system is monomitic, comprising only generative hyphae. Hyphae in the subiculum (a layer of loosely intertwined hyphae on the substrate that supports the fruit body) are thick-walled, hyaline to slightly yellowish, and encrusted. Other hyphae in the fruit body are somewhat to completely hyaline (translucent) and have a wall thickness ranging from thin to moderately thick. Cystidia are sparse and tubular, hyaline, thin-walled or have a slight wall thickening. The spores are ellipsoid, smooth, thin-walled, and generally measure up to 4–5 µm long. [5]
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.
Phanerochaete is a genus of crust fungi in the family Phanerochaetaceae.
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.
Auriporia is a small genus of four species of poroid fungi in the family Fomitopsidaceae.
Candelabrochaete is a genus of crust fungi in the family Phanerochaetaceae.
Roseograndinia is a fungal genus in the family Phanerochaetaceae. It is a monotypic genus, containing the single crust fungus species Roseograndinia rosea, recorded from tropical east Africa and from New Zealand.
Amethicium is a fungal genus in the family Phanerochaetaceae. A monotypic genus, it contains the single species Amethicium rimosum, a crust fungus first reported from Tanzania in 1983. Amethicium is primarily characterized by its purple fruit body and a dimitic hyphal system. The felt-like tissue layer covering the substrate comprises a thin layer of densely intertwined skeletal hyphae.
Cericium is a fungal genus in the family Cystostereaceae. It is a monotypic genus with the single species Cericium luteoincrustatum, a crust fungus. This species was originally described in 1986 by Kurt Hjortstam and Leif Ryvarden, who called it Amethicium luteoincrustatum. They placed it in the genus Amethicium based on microscopic similarities with the African species Amethicium rimosum.
Gloeohypochnicium is a genus of wood-inhabiting crust fungi of uncertain familial placement in the order Russulales. Originally conceived by Erast Parmasto as a subgenus of Hypochnicium, Kurt Hjortstam considered it worthy of distinct generic status in 1987. The type species, G. analogum, was described as new to science in 1913 by French mycologists Hubert Bourdot and Amédée Galzin as a species of Gloeocystidium. G. versatum was added to the genus in 2010.
Hyphoderma is a genus of crust fungi in the family Meruliaceae. It was circumscribed by German botanist Karl Friedrich Wilhelm Wallroth in 1833.
Hypochnicium is a genus of corticioid fungi in the family Meruliaceae. The genus was circumscribed by mycologist John Eriksson in 1958.
Uncobasidium is a genus of two species of crust fungi in the Meruliaceae family. The genus was circumscribed by mycologists Kurt Hjorstam and Leif Ryvarden in 1978 with the European fungus U. luteolum as the type species. The South American species U. roseocremeum was added to the genus in 2012. The distinguishing feature of Uncobasidium is the basal hook in the basidium.
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.
Lopharia is a genus of fungi in the family Polyporaceae. The genus was circumscribed by Károly Kalchbrenner and Peter MacOwan in 1881.
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.
Globuliciopsis is a genus of corticioid fungi in the order Polyporales. It currently contains two species found in Central and South America.
Hydnophlebia omnivora is a species of crust fungus in the family Meruliaceae. It causes white rot in various woody angiosperms, being found in arid regions of the Southern United States, northern Mexico, and Uruguay.
Mycoacia rubiginosa is a species of toothed crust fungus in the family Meruliaceae. It was described as a new species in 2004 by mycologists Kurt Hjortstam and Leif Ryvarden. The type collection was made in Sierra Nevada de Santa Marta, in Magdalena, Colombia, where the fungus was found growing on dead hardwood. It is known only from the type locality. Fruit bodies of M. rubiginosa are distinguished by their reddish colour, and spines up to 3 mm (0.12 in) long. The hyphal system is monomitic, containing only generative hyphae. The spores are ellipsoid, smooth, thin-walled and translucent, with dimensions of 4–4.5 by 2.5–2.75 µm.
