Tricholomataceae
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. The name derives from the Greek ''trichos'' (τριχος) meaning hair and ''loma'' (λωμα) meaning fringe or border, although not all members display this feature. The name "Tricholomataceae" is seen as having validity in describing ''Tricholoma'' and its close relatives, and whatever other genera can at some future point be described as part of a monophyletic family including ''Tricholoma''. To that end, the International Botanical Congress has voted on two occasions (1988 and 2006) to conserve the name "Tricholomataceae" against competing names. This decision does not invalidate the use of segregate families from the Tricholomataceae, but simply validates th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tricholomataceae Genera
The Tricholomataceae are a family of fungi in the order Agaricales. A 2008 estimate placed 78 genera and 1020 species in the family. In 2014, Sánchez-García and colleagues proposed a revised classification of the Tricholomataceae with seven genera: '' Leucopaxillus'', ''Tricholoma'', ''Dennisiomyces'', '' Porpoloma'', and the newly circumscribed genera '' Corneriella'', '' Pogonoloma'' and '' Pseudotricholoma''. Genera alt=A pair of pearly white mushrooms with a hairy cap surface and stem as well as low-hanging, thick gills. They are growing on dark, decaying leaves., ''Amparoina spinosissima'' image:Catathelasma imperiale.JPG, alt=A white and beige mushroom with a slightly warty surface and patches of dirt growing amongst dried conifer needles and moss.

Hygrophoraceae
The Hygrophoraceae are a family of fungi in the order Agaricales. Originally conceived as containing white-spored, thick-gilled agarics (gilled mushrooms), including ''Hygrophorus'' and ''Hygrocybe'' species (the waxcaps or waxy caps), DNA evidence has extended the limits of the family, so it now contains not only agarics, but also basidiolichens and corticioid fungi. Species are thus diverse and are variously ectomycorrhizal, lichenized, associated with mosses, or saprotrophic. The family contains 25 genera and over 600 species. None is of any great economic importance, though fruit bodies of some ''Hygrocybe'' and ''Hygrophorus'' species are considered edible and may be collected for sale in local markets. Taxonomy History The family Hygrophoraceae was first proposed by Dutch botanist Johannes Paulus Lotsy (1907) to accommodate agarics with thick, waxy lamellae (gills) and white spores. Lotsy's concept of the family included not only the waxcap-related genera ''Hygrophorus'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucopaxillus
''Leucopaxillus'' is a genus of fairly large white-spored gilled mushrooms which are found worldwide growing on the ground in woodlands. These are saprotrophs, but may sometimes be ectomycorrhizal. Less than ten species of ''Leucopaxillus'' are known to grow in North America. No species of ''Leucopaxillus'' are known to be poisonous, but they do not have an appealing taste or texture. The widespread genus contains about 15 species. Members of ''Leucopaxillus'' are medium-sized to large, have a dry convex to depressed cap, an inrolled margin when young, lack a partial veil and have tough flesh. They have white or yellowish gills which can come off in a layer, leaving the underside of the cap smooth. The spores are white, amyloid and spiny. These mushrooms often smell bad and can be mistaken for ''Tricholoma'' and ''Clitocybe'', but mushrooms in those genera are more fragile and rot more quickly. Members of ''Leucopaxillus'' have antibiotics which make the mushrooms persist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wastebasket Taxon
Wastebasket taxon (also called a wastebin taxon, dustbin taxon or catch-all taxon) is a term used by some taxonomists to refer to a taxon that has the sole purpose of classifying organisms that do not fit anywhere else. They are typically defined by either their designated members' often superficial similarity to each other, or their ''lack'' of one or more distinct character states or by their ''not'' belonging to one or more other taxa. Wastebasket taxa are by definition either paraphyletic or polyphyletic, and are therefore not considered valid taxa under strict cladistic rules of taxonomy. The name of a wastebasket taxon may in some cases be retained as the designation of an evolutionary grade, however. The term was coined in a 1985 essay by Steven Jay Gould. Examples There are many examples of paraphyletic groups, but true "wastebasket" taxa are those that are known not to, and perhaps not intended to, represent natural groups, but are nevertheless used as convenient groups ...

Marasmiaceae
The Marasmiaceae are a family of basidiomycete fungi which have white spores. They mostly have tough stems and the capability of shrivelling up during a dry period and later recovering. The widely consumed edible fungus ''Lentinula edodes'', the shiitake mushroom, is a member of this family. According to a 2008 estimate, the family contains 54 genera and 1590 species. The family Omphalotaceae, described by A. Bresinsky in 1985 as a segregate from the Tricholomataceae, has been considered synonymous with Marasmiaceae. However DNA analyses by Moncalvo et al. in 2002 and Matheny et al. in 2006 have now led to that family being accepted by Index Fungorum and most recent references. The following genera are included in that family : ''Anthracophyllum'', ''Gymnopus'', ''Lentinula'', ''Marasmiellus'', '' Mycetinis'', '' Rhodocollybia'', ''Omphalotus''.

Agaricales
The fungal order Agaricales, also known as gilled mushrooms (for their distinctive gills) or euagarics, contains some of the most familiar types of mushrooms. The order has 33 extant families, 413 genera, and over 13,000 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. History, classification and phylogeny In his three volumes of '' Systema Mycologicum'' published between 1821 and 1832, Elias Fries put almost all of the fleshy, gill-forming mushrooms in the genus ''Agaricus''. He organized the large genus into "tribes", the names of many of which still exist as common genera of today. Fries later elevated several of these tribes to generic level, but later authors—including Gillet, Karsten, Kummer, Quélet, and Staude—made most of the changes. Fries based his classification on ...

Tricholoma
''Tricholoma'' is a genus of fungus that contains many fairly fleshy white-spored gilled mushrooms which are found worldwide generally growing in woodlands. These are ectomycorrhizal fungi, existing in a symbiotic relationship with various species of coniferous or broad-leaved trees. The generic name derives from grc, τριχο-, tricho-, hair and grc, λῶμα, loma, fringe, border although only a few species (such as '' T. vaccinum'') have shaggy caps which fit this description. The most sought out species are the East Asian ''Tricholoma matsutake'', also known as ''matsutake'' or ''songi'', and the North American ''Tricholoma magnivelare'' species complex, also known as "ponderosa mushroom", "American matsutake", or "pine mushroom". Others are safe to eat, such as '' Tricholoma terreum'', but there are a few poisonous members, such as '' T. pardinum'', '' T. tigrinum'' and '' T. equestre''. Many species originally described within Tricholoma have since been moved to oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydnangiaceae
The Hydnangiaceae are a family of fungi in the mushroom order Agaricales. Widespread in temperate and tropical regions throughout the world, the family contains about 30 species in four genera. Species in the Hydnangiaceae form ectomycorrhizal relationships with various species of trees in both coniferous and deciduous forests. Description They may have fruit bodies with stipes and caps (pileate-stipiate), or gasteroid (with internal spore production, like puffballs). When pileate, the cap is smooth to scaly, sometimes striate, typically orange-brown or violet in color. The gills are widely spaced, thick, and waxy. In gasteroid forms, fruit body shape is irregular, with thin walls. Also, the peridium (the outer layer of the spore-bearing organ) is sometimes short-lasting (evanescent). Columella (the central, sterile part of the sporangium) may be absent or present, the hymenia are not gelatinized, and are formed in locules. Basidia are club-shaped (clavate), with two or four ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Pleurotaceae
The Pleurotaceae are a family of small to medium-sized mushrooms which have white spores. The family contains four genera ('' Nematoctonus'' has been synonymized with '' Hohenbuehelia'', but not all of its species have been moved to valid genera) and 94 species. Members of Pleurotaceae can be mistaken for members of Marasmiaceae. Perhaps the best known member is the oyster mushroom, ''Pleurotus ostreatus''. Many species in the genera '' Pleurotus'' and '' Hohenbuehelia'' are nematophagous, that is, they derive nutrition by consuming nematodes. This is made possible by hyphae A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or ... that may have adhesive knobs that attach to passing nematodes and secrete nematotoxic compounds. See also * List of Agaricales families References Externa ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
