Boreostereum is a genus of corticioid fungi. The genus was circumscribed in 1968 by Erast Parmasto to contain the type species, which was formerly known as Stereum radiatum. [1] Boreostereum has four species that are widely distributed in northern temperate areas. [2] Species in the genus have a dimitic hyphal system, and the hyphae have with brown encrustations that turn greenish when potassium hydroxide is applied. [3] Boreosterum vibrans produces vibralactones, chemical metabolites that inhibit various enzymes. [4] [5] Recent phylogenetic research indicates that Boreostereum is a sister group to the rest of the Gloeophyllales. [6]

Polyporales Order of fungi

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 forest and amenity 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.

<i>Neolentinus</i> Genus of fungi

Neolentinus is a genus of wood-decaying agarics with tough fruit bodies composed of dimitic tissue, serrated lamella edges, and nonamyloid white binucleate basidiospores among other features. It was segregated from Lentinus in the broad taxonomic sense, hence the derivation of the name. Biologically Neolentinus species produce a brown rot type of decay of wood, whereas Lentinus causes a white rot. Molecular phylogenetic analysis shows that the two genera are unrelated. Neolentinus is phylogenetically allied to other brown rot genera such as Gloeophyllum, Heliocybe, and Veluticeps. A new order, the Gloeophyllales, has been described for these fungi. Heliocybe had been placed in synonymy but it differs phylogenetically and anatomically by the lack of clamp connections that all Neolentinus produce on their generative hyphae.

Dothideomycetes Class of fungi

Dothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1300 genera and over 19,000 known species. Traditionally, most of its members were included in the loculoascomycetes, which is not part of the currently accepted classification. This indicates that several traditional morphological features in the class are not unique and DNA sequence comparisons are important to define the class.

Clavulinaceae Family of fungi

The Clavulinaceae are a family of fungi in the order Cantharellales. The family is not well defined, but currently comprises species of clavarioid fungi as well as some corticioid fungi. These species are nutritionally diverse, some being ectomycorrhizal, others wood-rotting saprotrophs, others lichenized, and yet others lichenicolous.

Pezizomycetes Class of fungi

Pezizomycetes are a class of fungi within the division Ascomycota.

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.

Gomphales Order of fungi

The Gomphales are an order of basidiomycete fungi. Some or all families belonging to Gomphales have been sometimes included in the order Phallales, the now-obsolete Ramariaceae was also previously included in Cantharellales. Recent phylogenetic analyses include in Gomphales the families of the original description of the order by Walter Jülich, with addition of Clavariadelphaceae. According to one 2008 estimate, the Gomphales contain 18 genera and 336 species.

<i>Phanerochaete</i> Genus of fungi

Phanerochaete is a genus of crust fungi in the family Phanerochaetaceae.

<i>Heliocybe</i> Genus of fungi

Heliocybe is an agaric genus closely allied to Neolentinus and the bracket fungus, Gloeophyllum, all of which cause brown rot of wood. Heliocybe sulcata, the type and sole species, is characterized by thumb-sized, tough, revivable, often dried, mushroom fruitbodies, with a tanned symmetric pileus that is radially cracked into a cartoon sun-like pattern of arranged scales and ridges, distant serrated lamellae, and a scaly central stipe. Microscopically it differs from Neolentinus by the absence of clamp connections. Like Neolentinus, it produces abundant, conspicuous pleurocystidia. Heliocybe sulcata typically fruits on decorticated, sun-dried and cracked wood, such as fence posts and rails, vineyard trellises in Europe, branches in slash areas, and semi-arid areas such on sagebrush or on naio branches in rain shadow areas of Hawaii, or in open pine forests.

<i>Gloeophyllum</i> Genus of fungi

The genus Gloeophyllum is characterized by the production of leathery to corky tough, brown, shaggy-topped, revivable fruitbodies lacking a stipe and with a lamellate to daedaleoid or poroid fertile hymenial surfaces. The hyphal system is dimitic to trimitic. The genus is further characterized by the production of a brown rot of wood. Phylogenetically, it along with several other brown rot Basidiomycota, Neolentinus, Heliocybe, and Veluticeps form an order called the Gloeophyllales.

Veluticeps is a small genus of wood-rot fungi characterized by the production of resupinate to bracket shaped, perennial, tough, brown fruitbodies, that blacken when KOH solution is applied, and with a smooth to warted or cracked fertile undersurface. They cause a brown rot of wood. Cystidia in the hymenium are characteristically mostly in fascicles. The genus may be monotypic if Columnocystis is excluded. Phylogenetically, the type species, V. berkeleyi, groups with several other brown rot genera such as Neolentinus, Heliocybe, and Gloeophyllum.

<i>Hydnellum</i> Genus of fungi in the family Bankeraceae

Hydnellum is a genus of tooth fungi in the family Bankeraceae. Widely distributed in the Northern Hemisphere, the genus contains around 40 species. The fruitbodies of its members grow by slowly enveloping nearby bits of grass and vegetation. There is great variability in the form of Hydnellum fruitbodies, which are greatly influenced by environmental conditions such as rainfall and humidity, drying winds, and temperature. They are too tough and woody to eat comfortably. Several species have become the focus of increasing conservation concern following widespread declines in abundance.

Phanerochaetaceae Family of fungi

The Phanerochaetaceae are a family of mostly crust fungi in the order Polyporales.

<i>Phlebia</i> Genus of fungi

Phlebia is a genus of mostly crust fungi in the family Meruliaceae. The genus has a widespread distribution. Phlebia species cause white rot.

<i>Amauroderma</i> Genus of fungi

Amauroderma is a genus of polypore fungi in the family Ganodermataceae. The genus, widespread in tropical areas, contains about 70 species. Amauroderma fungi are wood-decay fungi that feed and fruit on decayed branches and trunks.

<i>Datronia</i> Genus of fungi

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.

<i>Dentocorticium</i> Genus of fungi

<i>Fibroporia</i> Genus of fungi

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.
