Loweomyces is a genus of six species of poroid fungi in the family Steccherinaceae (formerly placed in the Meruliaceae). [2]
It was originally circumscribed as a subgenus of Spongipellis by the Czech mycologists František Kotlaba and Zdeněk Pouzar in 1976. [3] Swiss mycologist Walter Jülich promoted it to a genus segregate from Spongipellis in 1982, with two species: L. fractipes (the type), and L. wynneae . Jülich thought the genus should be distinct from Spongipellis based on the larger basidia, the absence of skeletal hyphae, and smaller tubes. [4] L. fractipes and L. wynneae have had their generic positions confirmed with molecular phylogenetics, and both group in the "residual polyploid clade", one of four main lineages of the Polyporales. [2] [5] The genus is named in honour of American mycologist and polypore specialist Josiah Lincoln Lowe. [6]
Loweomyces is distinguished by the ease of spore germination in growth media, larger basidia, the absence of skeletal hyphae, and smaller tubes, plates or spines, compared with European Spongipellis species. [4] Fruit bodies are either crust-like or have a cap and stipe. The hyphal system is either monomitic (possessing only generative hyphae) or dimitic (having both generative and pseudo-skeletal hyphae). [7]
The genus contained four species as of January 2015 [update] . [8] Two new species from Brazil were described in 2016. [7]
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.
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.
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).
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").
Pachykytospora is a small genus of poroid fungi in the family Polyporaceae. Species in the cosmopolitan genus cause white rot. There are about 10 species in the genus, with newest member described from European Russia in 2007. Pachykytospora species have fruit bodies that are resupinate, with light brown tubes. They are characterized by their uneven, ellipsoid spores, and the Polyporus-like skeletal-binding hyphae.
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.
Frantisekia is a genus of wood-decay fungi in the family Steccherinaceae.
Trulla is a fungal genus in the family Steccherinaceae containing six species of polypores. It was circumscribed by mycologists Otto Miettinen and Leif Ryvarden in 2016, as a continuation of prior work that outlined a revised framework for the Steccherinaceae based on molecular phylogenetics. Its closest relative in the Steccherinaceae is the genus Nigroporus, from which it differs in its light-coloured fruit bodies and monomitic context.
Metuloidea is a genus of five species of fungi in the family Steccherinaceae. The genus was circumscribed by New Zealand-based mycologist Gordon Herriot Cunningham in 1965. The type species is M. tawa, a fungus originally described by Cunningham as a species of Trametes. Formerly classified in family Meruliaceae, Metuloidea was moved to the Steccherinaceae in 2016, following prior research that outlined a revised framework for the Steccherinaceae based on molecular phylogenetics.
Loweomyces fractipes is a species of poroid fungus in the family Steccherinaceae, and the type species of the genus Loweomyces. It is a widely distributed species, found in North America, Europe, Central America, South America, and Korea.
The Gelatoporiaceae are a small family of crust fungi in the order Polyporales. The family was circumscribed in 2017 by mycologists Otto Miettinen, Alfredo Justo and David Hibbett to contain the type genus Gelatoporia and three other related genera, Cinereomyces, Obba, and Sebipora.
The Irpicaceae are a family of mostly polypores and crust fungi in the order Polyporales.
