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.
Erast Parmasto first described Dentocorticium in 1968 as a section of Laeticorticium, a defunct genus that was classified in the Corticiaceae. [1] Dentocorticium was raised to generic status by M.J. Larsen and Robert Lee Gilbertson in 1974. [2]
Dendrodontia and Fuscocerrena were shown to be synonyms of Dentocorticium in a 2018 phylogenetic analyses. [3] Dendrodontia was circumscribed by Kurt Hjortstam and Leif Ryvarden in 1980 to contain Dendrodontia bicolor (formerly Grandinia bicolor). [4] Fuscocerrena was created by Ryvarden in 1982 to house Fuscocerrena portoricensis. [5]
The fruit bodies of Dentocorticium fungi are annual. They range from effused (crust-like), to effused-reflexed (crust-like with edges curling to form rudimentary caps) or cap-like, with a texture ranging from membranous, to leathery or soft corky. The spore-bearing surface are often tooth-like, bumpy with tubercles, or spiny. In some species the surface is poroid, daedaleoid (maze-like), and sometimes develops irregular ridges or hyphal pegs (bundles of hyphae that project from the hymenium). [3]
Dentocorticium has a dimitic or trimitic hyphal system. The generative hyphae have clamp connections. There are brown skeletal hyphae present in the subiculum (a layer of loosely intertwined hyphae forming a mat covering the substrate and underlying the fruit body), spine trama, and hyphal pegs. Microbinding hyphae may be present in the subiculum or the substrate. Dendrohyphidia are present. Cylindrical to somewhat spindle shaped cystidia may be present. Basidia are club shaped and have four sterigmata. Spores are ellipsoid to cylindrical in shape, translucent with thin walls, and smooth. They do not react with Melzer's reagent, and acyanophilous (having cell walls that do not readily absorb cotton blue stain). [3]
Several species once placed in this genus were transferred elsewhere:
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.
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.
Scopuloides is a genus of five species of crust fungi in the family Meruliaceae.
Phlebia is a genus of mostly crust fungi in the family Meruliaceae. The genus has a widespread distribution. Phlebia species cause white rot.
Hjortstamia is a genus of corticioid fungi in the family Phanerochaetaceae. It was circumscribed by French mycologists Jacques Boidin and Gérard Gilles in 2003.
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.
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.
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.
Epithele is a genus of crust fungi in the family Polyporaceae.
Xenasmatella is a genus of corticioid fungi in the order Polyporales. Circumscribed by German mycologist Franz Oberwinkler in 1966, the widespread genus contains 27 species.
Crustodontia is a fungal genus of uncertain familial placement in the order Polyporales. The genus was circumscribed in 2005 to contain the crust fungus Crustodontia chrysocreas. This species was originally described as Corticium chrysocreas by Miles Berkeley and Moses Ashley Curtis in 1873. Their description was as follows: "Subiculum bright yellow, thin; hymenium immarginate pallid, or yellow tinged with tawny." Crustodontia has a monomitic hyphal system, meaning it contains only generative hyphae, and these hyphae have clamp connections.
The Irpicaceae are a family of mostly polypores and crust fungi in the order Polyporales.
Efibula is a genus of 16 species of crust fungi in the family Irpicaceae.
Kurt Egon Hjortstam (1933–2009) was a Swedish mycologist, specialising in the taxonomy of corticioid fungi.
