They are fan- or spoon-shaped and attached to the substrate (biology), substrate by a short stipe (mycology), stipe. The upper surface of the cap is initially velutinous–covered with short, dense, silky, upright hairs, particularly near its base. In age the surface becomes smoother.

Polyporaceae
The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft (as in the case of the dryad's saddle illustrated) to very tough. Most members of this family have their hymenium (fertile layer) in vertical pores on the underside of the caps, but some of them have gills (e.g. ''Panus'') or gill-like structures (such as ''Daedaleopsis'', whose elongated pores form a corky labyrinth). Many species are brackets, but others have a definite stipe – for example, '' Polyporus badius''. Most of these fungi have white spore powder but members of the genus '' Abundisporus'' have colored spores and produce yellowish spore prints. Cystidia are absent. Taxonomy In his 1838 work ''Epicrisis Systematis Mycologici seu Synopsis Hymenomycetum'', Elias Magnus Fries introduced the "Polyporei". August Corda published the name validly the following year, retaining Fries's concept. American mycologist William Alphonso Murrill, ...

Polyporus
''Polyporus'' is a genus of poroid fungi in the family Polyporaceae. Taxonomy Italian botanist Pier Antonio Micheli introduced the genus in 1729 to include 14 species featuring fruit bodies with centrally-placed stipes, and pores on the underside of the cap. The generic name combines the Ancient Greek words ("many") and ("pore"). Elias Fries divided ''Polyporus'' into three subgenera in his 1855 work ''Novae Symbol Mycologici'': ''Eupolyporus'', ''Fomes'', and ''Poria''. In a 1995 monograph, Maria Núñez and Leif Ryvarden grouped 32 ''Polyporus'' species into 6 morphologically-based infrageneric groups: ''Admirabilis'', ''Dendropolyporus'', ''Favolus'', ''Polyporellus'', ''Melanopus'', and ''Polyporus'' ''sensu stricto''. The identity of the type species of ''Polyporus'' has long been a matter of contention among mycologists. Some have preferred '' P. brumalis'', some '' P. squamosus'', while others have preferred '' P. tuberaster''. Several molecular phylo ...

Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from el, ὑάλινος, translit=hyálinos, lit=transparent, and el, ὕαλος, translit=hýalos, lit=crystal, glass, label=none. Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining. Ichthyology and entomology In ichthyology and entomology, ''hyaline'' denotes a colorless, transparent substance, such as unpigmented fins of fishes or clear insect wings. Resh, Vincent H. and R. T.

Clamp Connection
A clamp connection is a hook-like structure formed by growing hyphal cells of certain fungi. It is a characteristic feature of Basidiomycetes fungi. It is created to ensure that each cell, or segment of hypha separated by septa (cross walls), receives a set of differing nuclei, which are obtained through mating of hyphae of differing sexual types. It is used to maintain genetic variation within the hypha much like the mechanisms found in crozier (hook) during sexual reproduction. Formation Clamp connections are formed by the terminal hypha during elongation. Before the clamp connection is formed this terminal segment contains two nuclei. Once the terminal segment is long enough it begins to form the clamp connection. At the same time, each nucleus undergoes mitotic division to produce two daughter nuclei. As the clamp continues to develop it uptakes one of the daughter (green circle) nuclei and separates it from its sister nucleus. While this is occurring the remaining nuclei ...

Trama (mycology)
In mycology, the term trama is used in two ways. In the broad sense, it is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium. In essence, the trama is the tissue that is commonly referred to as the "flesh" of mushrooms and similar fungi.Largent D, Johnson D, Watling R. 1977. ''How to Identify Mushrooms to Genus III: Microscopic Features''. Arcata, CA: Mad River Press. . pp. 60–70. The second use is more specific, and refers to the "hymenophoral trama" that supports the hymenium. It is similarly interior, connective tissue, but it is more specifically the central layer of hyphae running from the underside of the mushroom cap to the lamella or gill, upon which the hymenium rests. Various types have been classified by their structure, including trametoid, cantharelloid, boletoid, and agaricoid, with agaricoid the ...

Dextrinoid
In mycology a tissue or feature is said to be amyloid if it has a positive amyloid reaction when subjected to a crude chemical test using iodine as an ingredient of either Melzer's reagent or Lugol's solution, producing a blue to blue-black staining. The term "amyloid" is derived from the Latin ''amyloideus'' ("starch-like"). It refers to the fact that starch gives a similar reaction, also called an amyloid reaction. The test can be on microscopic features, such as spore walls or hyphal walls, or the apical apparatus or entire ascus wall of an ascus, or be a macroscopic reaction on tissue where a drop of the reagent is applied. Negative reactions, called inamyloid or nonamyloid, are for structures that remain pale yellow-brown or clear. A reaction producing a deep reddish to reddish-brown staining is either termed a dextrinoid reaction (pseudoamyloid is a synonym) or a hemiamyloid reaction. Melzer's reagent reactions Hemiamyloidity Hemiamyloidity in mycology refers to a special c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
