Neolentiporus
''Neolentiporus'' is a fungal genus in the family Fomitopsidaceae. It contains '' Neolentiporus squamosellus'' and the type species '' N. maculatissimus''. The genus was circumscribed by mycologist Mario Rajchenberg in 1995. Description ''Neolentiporus'' is characterized by medium to large fruit bodies that have stipes and a poroid hymenium on the cap underside. The caps are circular to fan-shaped with a scaly surface, and have an off-centre or lateral stipe that sometimes is reduced to a short, robust umbo. The hyphal system is dimitic with clamped, irregularly thick-walled generative hyphae that do not react with cresyl-blue stain. The skeletal hyphae are unbranched, thick-walled, and are strongly metachromatic in cresyl-blue. Spores are cylindrical, hyaline, thin-walled, inamyloid, and binucleate. ''Neolentiporus'' causes a brown rot. Molecular phylogenetic analysis shows ''Neolentiporus'' to be closely related to ''Buglossoporus ''Buglossoporus'' is a genus of fungi ...

Fomitopsidaceae
The Fomitopsidaceae are a family of fungi in the order Polyporales. Most species are parasitic on woody plants, and tend to cause brown rots. The name comes from ''Fomitopsis'' (meaning "looking like Fomes") + ''-aceae'' (a suffix used to form taxonomic family names). Genera In a proposed family-level classification of the Polyporales based on molecular phylogenetics 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 ..., Alfredo Justo and colleagues accept 14 genera in the Fomitopsidaceae: '' Anthoporia'', ''Antrodia'', ''Buglossoporus'', '' Cartilosoma'', ''Daedalea'', ''Fomitopsis'', ''Fragifomes'', '' Melanoporia'', ''Neolentiporus'', ''Niveoporofomes'', '' Rhodofomes'', ''Rhodofomitopsis'', ''Rubellofomes'', and ''Ungulidaedalea''.

Buglossoporus
''Buglossoporus'' is a genus of fungi in the family Fomitopsidaceae. The genus was circumscribed in 1966 by Czech mycologists František Kotlába and Zdeněk Pouzar, with '' Buglossoporus quercinus'' as the type species. In some works, ''Buglossoporus'' has been treated as a synonym of ''Piptoporus''. '' Buglossoporus magnus'', known from only three locations in old growth lowland rainforest of Peninsular Malaysia, is considered a vulnerable species by the IUCN, and appears on their Red List. Description The fruit bodies of ''Buglossoporus'' are annual. They have a cap, and a variable attachment to the substrate—in some species the cap is attached directly, while others have a stipe. The cap surface ranges in colour from pink, cinnamon, orange to brown, with a texture that is either felt-like or smooth, without zone lines. The pore surface on the cap underside is white, cream, buff to brown. Pores are small, with a round to angular shape. The context is white, cream, buff, o ...

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] |

Wood-decay Fungus
A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot. Some species of wood-decay fungi attack dead wood, such as brown rot, and some, such as ''Armillaria'' (honey fungus), are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal colonization and proliferation. In nature, this process causes the breakdown of complex molecules and leads to the return of nutrients to the soil. Wood-decay fungi consume wood in various ways; for example, some attack the carbohydrates in wood and some others decay lignin. The rate of decay of wooden materials in various climates can be estimated by empirical models.Viitanen, T. et al. (2010). Towards modelling of decay risk of wooden materials. European Journal of Wood and Wood Products 68:303-313. Wood-decay fungi can be classified according to the type of decay that they cause. The best-known types are brown rot, soft rot, and whit ...

Inamyloid
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the ...

Metachromasia
Metachromasia (var. metachromasy) is a characteristical change in the color of staining carried out in biological tissues, exhibited by certain dyes when they bind to particular substances present in these tissues, called chromotropes. For example, toluidine blue becomes dark blue (with a colour range from blue-red dependent on glycosaminoglycan content) when bound to cartilage. Other widely used metachromatic stains are the haematological Giemsa and May-Grunwald stains that also contain thiazine dyes. The white cell nucleus stains purple, basophil granules intense magenta, whilst the cytoplasms (of mononuclear cells) stains blue. The absence of color change in staining is named orthochromasia. The underlying mechanism for metachromasia requires the presence of polyanions within the tissue. When these tissues are stained with a concentrated basic dye solution, such as toluidine blue, the bound dye molecules are close enough to form dimeric and polymeric aggregates. The light a ...
