Steccherinaceae
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. Taxonomy The family was circumscribed by Czech mycologist Erast Parmasto in 1968. Parmasto's original concept included species that are today classified in the Agaricales, Hymenochaetales, Polyporales, and Russulales. A large-scale molecular study published in 2012 by Otto Miettinen and colleagues redefined the limits of the Steccherinaceae to include most species of the poroid and hydnoid genera '' Antrodiella'', '' Junghuhnia'', and ''Steccherinum'', as well as members of 12 other hydnoid and poroid genera. These genera were traditionally classified in the families Phanerochaetaceae, Polyporaceae, and Meruliaceae. They commented: "we see the need for at least 30 monophyletic, morphologically distinguishable genera. These include no fewer than 15 new genera for both polypores and hydnoid fungi, and r ...

Trulla
''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. The generic name ''Trulla'', from the Latin word for "ladle", alludes to the spatulate (spoon-like) shape of the fruit bodies. Microscopic characteristics of the genus include spores that are curved and cylindrical, cyanophilic skeletal hyphae (staining blue if the microscopic stain Lactophenol Cotton Blue is applied) and slightly thick-walled, wide generative hyphae in the context. Species ''Trulla'' contains six species that were transferred from various other polypore genera, including '' Antrodiella'', ''Polyporus'', '' Leptoporus' ...

Polyporales
The Polyporales are an order of about 1800 species of fungi in the division Basidiomycota. The order includes some (but not all) polypores as well as many corticioid fungi and a few agarics (mainly in the genus ''Lentinus''). 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. Taxonomy History The order was originally proposed in 1926 by Swiss mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota producing basidiocarps (fruit bodies) showing a gymnocapous mode of development (forming the spore-bearing surface ext ...

Mycorrhaphium
''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'' (formerly referred to '' Hydnum''). 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. Walter Jülich created the family Mycorrhaphiaceae to contain the type genus ''Mycorrhaphium''. This family is now placed in synonymy with Steccherinaceae.

Antrodiella
''Antrodiella'' is a genus of fungi in the family Steccherinaceae of the order Polyporales. Taxonomy ''Antrodiella'' was circumscribed by mycologists Leif Ryvarden and I. Johansen in 1980. Of the seven original species it contained, only the type, '' Antrodiella semisupina'', remains in the genus; most of the original species have since been transferred to '' Flaviporus''. ''Antrodiella'' was traditionally placed in the family Phanerochaetaceae until molecular studies were used to determine a more appropriate classification in the Steccherinaceae. The genus is a wastebasket taxon, containing "species that share common macroscopic and microscopic characteristics, but are not necessarily related." Description The fruitbodies of ''Antrodiella'' fungi are either crust-like to effused-reflexed (stretched out on the substrate but with edges curled up to form cap-like structures) in form. They have a waxy and soft fresh texture that becomes dense and hard, and often semitra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butyrea
''Butyrea'' is a genus of two species of crust fungi in the family Steccherinaceae. Taxonomy The genus was circumscribed by Finnish mycologist Otto Miettinen in 2016 with '' Butyrea luteoalba'' as the type species. This fungus was originally described as ''Physisporus luteoalbus'' by Petter Karsten in 1887. The generic name, derived from the Latin word ''butyrum'' ("butter"), refers to the oil-containing cells (gloeocystidia) that are characteristic of the genus. Description ''Butyrea'' species are poroid with annual, yellowish, crust-like basidiocarps and minute pores numbering 4–8 per millimetre. The hyphal system is dimitic, containing both generative hyphae (with clamps) and skeletal hyphae. The skeletal hyphae are moderately cyanophilous (with cell walls that absorb cotton blue stain), narrow and sinuous, measuring mostly less than 2.5 µm wide with a distinct lumen that is 1/3–1/2 of the width. Two types of cystidia are present: there are thin-walled gloeocysti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antella (fungus)
''Antella'' is a genus of three species of crust fungi in the family Steccherinaceae. Taxonomy The genus was circumscribed by Finnish mycologist Otto Miettinen in 2016 with '' Antella niemelaei'' as the type species. All three species were formerly classified in the polyphyletic genus ''Antrodiella''. This is reflected in the name ''Antella'', which is a "construct of letters from the genus name ''Antrodiella''." Description ''Antella'' species have light-coloured, crust-like fruit bodies with a poroid surface. They have a dimitic hyphal system, with both generative and skeletal hyphae, and clamp connections in the hyphae. The thin-walled spores are ellipsoid, measuring less than 4.5 by 2.5 μm The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Unit ....

Steccherinum
''Steccherinum'' is a widely distributed genus of toothed crust fungi in the family Steccherinaceae. Taxonomy ''Steccherinum'' was circumscribed by Samuel Frederick Gray in his 1821 work ''A Natural Arrangement of British Plants''. Description ''Steccherinum'' fungi have a range of fruit body morphologies, including resupinate (crust-like), effused-reflexed (crust-like with the edges extending outwards to form caps), or pileate with either a stipe or only a stipe-like base. Species A 2008 estimate placed 33 species in ''Steccherinum''. , Index Fungorum accepts 50 species: *'' S. agaricoides'' (Sw.)

Meruliaceae
The Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. , Index Fungorum accepts 645 species in the family. Taxonomy The family was formally circumscribed by English mycologist Carleton Rea in 1922, with ''Merulius'' as the type genus. He also included the genera ''Phlebia'', '' Coniophora'' (now placed in the Coniophoraceae), and ''Coniophorella'' (now considered a synonym of ''Coniophora''). His description of the Meruliaceae was as follows: "Hymenium spread over veins, anastomosing pores, or quite smooth; ''edge of veins or pores fertile.''" Several genera formerly classified in the Meruliaceae were moved to the family Steccherinaceae based on molecular evidence. Description Meruliaceae species are crust-like or polyporoid, and often have a waxy appearance when dry. Their hyphal systems are monomitic (containing only tightly arranged generative hyphae), and these hyphae have clamp connec ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Basidiomycota
Basidiomycota () is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. Members are known as basidiomycetes. More specifically, Basidiomycota includes these groups: mushrooms, puffballs, stinkhorns, bracket fungi, other polypores, jelly fungi, boletes, chanterelles, earth stars, smuts, bunts, rusts, mirror yeasts, and ''Cryptococcus'', the human pathogenic yeast. Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores. However, some Basidiomycota are obligate asexual reproducers. Basidiomycota that reproduce asexually (discussed below) can typically be recognized as members of this division by gross similarity to others, by the form ...
