Neolentinus is a genus of wood-decaying agarics with tough (leathery to woody) fruit bodies composed of dimitic tissue, serrated lamella edges, and nonamyloid white binucleate basidiospores among other features. [2] 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. [3] [4] [5] [6] 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. [7] [8] 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.

Species

The best known species in this genus is Neolentinus lepideus , sometimes known as the "train wrecker", a name coined because the fungus is one of the few decay fungi that can grow on creosote-treated railroad ties. Neolentinus lepideus also grows on timbers in old mines, but because it requires light to form its cap, the fungus forms bizarre growth forms when fruit bodies start to form in dark mine shafts or cellars. Neolentinus lepideus is widely distributed.

Neolentinus kauffmanii decays sitka spruce on the west coast of North America, producing a variation of brown rot called brown pocket rot. Neolentinus ponderosus is another western North American species found on the ground, growing from the roots of or growing from the stumps of pine, predominantly Pinus ponderosa in montane areas. In California, it is often solitary, common in the Sierra, and is rare at low elevations. The fruiting commences from late spring to late summer. Sought out when young and tender, it has an excellent taste.

Neolentinus dactyloides is a fire ecology species that fruits from massive subterranean pseudosclerotia in Australia.

Etymology

Neolentinus means the new (Latin - neo-) Lentinus. Lentinus is an older generic name historically applied to a broad group of agarics, and now restricted in application excluding Neolentinus.

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.

Agaricales order of fungi

The fungal order Agaricales, also known as gilled mushrooms or euagarics, contains some of the most familiar types of mushrooms. The order has 33 extant families, 413 genera, and over 13000 described species, along with six extinct genera known only from the fossil record. They range from the ubiquitous common mushroom to the deadly destroying angel and the hallucinogenic fly agaric to the bioluminescent jack-o-lantern mushroom.

Strophariaceae family of fungi

The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith.

<i>Pleurotus</i> genus of fungi

Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms, P. ostreatus. Species of Pleurotus may be called oyster, abalone, or tree mushrooms, and are some of the most commonly cultivated edible mushrooms in the world. Pleurotus fungi have been used in mycoremediation of pollutants such as petroleum and polycyclic aromatic hydrocarbons.

Tricholomataceae family of fungi

The Tricholomataceae are a large family of mushrooms within the Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae.

Agaricomycetes class of fungi

The Agaricomycetes are a class of fungi in the division Basidiomycota. The taxon is roughly identical to that defined for the Homobasidiomycetes by Hibbett & Thorn, with the inclusion of Auriculariales and Sebacinales. It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. Within the subdivision Agaricomycotina, which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes, which are generally considered to be jelly fungi. However, a few former "jelly fungi", such as Auricularia, are classified in the Agaricomycetes. According to a 2008 estimate, Agaricomycetes include 17 orders, 100 families, 1147 genera, and about 21000 species. Modern molecular phylogenetic analyses have been since used to help define several new orders in the Agaricomycetes: Amylocorticiales, Jaapiales, Stereopsidales, and Lepidostromatales.

Sclerodermataceae family of fungi

The Sclerodermataceae are a family of fungi in the order Boletales, containing several genera of unusual fungi that little resemble boletes. Taxa, which include species commonly known as the ‘hard-skinned puffballs’, ‘earthballs’, or 'earthstars', are widespread in both temperate and tropical regions. The best known members include the earthball Scleroderma citrinum, the dye fungus Pisolithus tinctorius and the 'prettymouths' of the genus Calostoma.

<i>Neolentinus ponderosus</i> species of fungus

Neolentinus ponderosus, commonly known as the giant sawgill, is a species of fungus in the family Gloeophyllaceae. Found in western North America, it was originally described in 1965 as a species of Lentinus by American mycologist Orson K. Miller.

<i>Neolentinus lepideus</i> species of fungus

Neolentinus lepideus is a basidiomycete mushroom of the genus Neolentinus, until recently also widely known as Lentinus lepideus. Common names for it include scaly lentinus and train wrecker.

<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.

Gloeophyllales order of fungi

The Gloeophyllales are a phylogenetically defined order of wood-decay fungi that is characterized by the ability to produce a brown rot of wood. It includes a single, identically defined family, the Gloeophyllaceae, in which are included the genera Gloeophyllum, Neolentinus, Heliocybe, and Veluticeps.

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>Pholiota</i> genus of fungi

Pholiota is a genus of small to medium-sized, fleshy mushrooms in the family Strophariaceae. They are saprobes that typically live on wood. The genus has a widespread distribution, especially in temperate regions, and contains about 150 species.

Atheliales order of fungi

The Atheliaceae are a family composed exclusively of corticioid fungi, placed under the monotypic order Atheliales. Both the order and the family were described by Walter Jülich in 1981. According to a 2008 estimate, the family contains 20 genera and approximately 100 species. However, many genera formerly considered to belong in the Atheliaceae have since been moved to other families, including Amylocorticiaceae, Albatrellaceae, and Hygrophoraceae. Despite being a relatively small group with inconspicuous forms, Atheliaceae members show great diversity in life strategies and are widespread in distribution. Additionally, being a group strictly composed of corticioid fungi, they may also provide insights on the evolution of fruiting body forms in basidiomycetes.

Mycenaceae family of fungi

The Mycenaceae are a family of fungi in the order Agaricales. According to the Dictionary of the Fungi, the family contains 10 genera and 705 species. This is one of several families that were separated from the Tricholomataceae as a result of phylogenetic analyses. Taxa in the Mycenaceae are saprobic, have a cosmopolitan distribution, and are found in almost all ecological zones. The family was circumscribed by Caspar van Overeem in 1926.

<i>Trichaptum</i> genus of fungi

Trichaptum is a genus of poroid fungi. The genus was circumscribed by American mycologist William Alphonso Murrill in 1904. Formerly classified in the family Polyporaceae, several molecular studies have shown that the genus belongs to the order Hymenochaetales.

Amylocorticiales order of fungi

Amylocorticiales is an order of fungi in the class Agaricomycetes. The order was circumscribed in 2010 to contain mostly resupinate (crust-like) forms that have been referred to genera Anomoporia, Amyloathelia, Amylocorticiellum, Amylocorticium, Amyloxenasma, Anomoloma, Athelia, Athelopsis, Ceraceomyces, Hypochniciellum, Leptosporomyces and Serpulomyces.

Pleurotoid fungi

Gilled fungi with laterally-attached fruiting bodies are said to be pleurotoid. Pleurotoid fungi are typically wood-decay fungi and are found on dead and dying trees and coarse woody debris. The pleurotoid form is polyphyletic, having evolved a number of times within the Basidiomycota. Many species of pleurotoid fungi are commonly referred to as "oyster" mushrooms. Laterally-attached fungi with pores rather than gills are referred to as bracket fungi.

Sclerodermatineae suborder of fungi

Sclerodermatineae is a suborder of the fungal order Boletales. Circumscribed in 2002 by mycologists Manfred Binder and Andreas Bresinsky, it contains nine genera and about 80 species. The suborder contains a diverse assemblage fruit body morphologies, including boletes, gasteroid forms, earthstars, and puffballs. Most species are ectomycorrhizal, although the ecological role of some species is not known with certainty. The suborder is thought to have originated in the late Cretaceous (145–66 Ma) in Asia and North America, and the major genera diversified around the mid Cenozoic (66–0 Ma).
