Tremella Aurantia
''Naematelia aurantia'' (synonym ''Tremella aurantia'') is a species of fungus producing yellow, frondose, gelatinous basidiocarps (fruit bodies). It is widespread in north temperate regions and is parasitic on another species of fungus ('' Stereum hirsutum'') that grows on dead attached and recently fallen branches of broadleaf trees. It is commonly called golden ear in North America. Taxonomy ''Tremella aurantia'' was first published in 1822 by German-American mycologist Lewis David de Schweinitz, based on collections from North Carolina. In 1921, the species was transferred to ''Naematelia'' by Edward Angus Burt, but remained better known as ''Tremella aurantia'' until molecular research, based on cladistic analysis of DNA sequences, showed that ''Naematelia'' was a distinct genus. The epithet ''aurantia'' means "golden". Description Fruit bodies are gelatinous, bright yellow, up to 15 cm (6 in) across, and lobed to frondose (like seaweed). Microscopically, t ...

Stereum
''Stereum'' is the type genus of the Stereaceae family of fungi, in the Russulales order. Until recently, the genus was classified in the Corticiaceae family, of the Corticiales order. However, it was given its own family as a result of the split-up of the Corticiales. Common names for species of this genus include leaf fungus, wax fungus, and shelf fungus. Fungi having a shape similar to a ''Stereum'' are said to have a stereoid shape. ''Stereum'' contains 27 species that have a widespread distribution. Habitat ''Stereum'' species are found to live on all kinds of deadwood or hardwood or dead leaves (they are therefore said to be saprobic). Sometimes they are also found on living leaves. Characteristics ''Stereum'' species are wood decay fungi. Their simple, shelving fruiting bodies have a smooth hymenium, lacking gills or tubes. Like most members or the family Stereaceae, ''Stereum'' fruiting bodies lack clamp connections and produce amyloid basidiospores. The species can be ...

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 more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 µm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. ...

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

Dacrymycetales
The Dacrymycetes are a class of fungi in the Basidiomycota. The class currently contains the single order Dacrymycetales, with a second proposed order Unilacrymales now treated at the family level. The order contains four families and has a cosmopolitan distribution. All fungi in the Dacrymycetes are wood-rotting saprotrophs. Basidiocarps (fruit bodies) are ceraceous to gelatinous, typically yellow to orange as a result of carotenoid pigments, and variously corticioid (effused and patch-forming), disc- or cushion-shaped, spathulate, or clavarioid (club or coral-like). Microscopically, nearly all species have distinctive Y-shaped holobasidia. Species were formerly placed in the Heterobasidiomycetes Heterobasidiomycetes, including jelly fungi, smuts and rusts, are basidiomycetes with Septum, septate Basidium, basidia. This contrasts them to homobasidiomycetes (alternatively called holobasidiomycetes), including most mushrooms and other Agari ... and are informally included in ...

Dacrymyces Chrysospermus
''Dacrymyces chrysospermus'' is a species of jelly fungus in the family (biology), family Dacrymycetaceae. In the UK it has the recommended English name of orange jelly spot; in North America it is known as orange jelly or orange witch's butter. The species is saprotrophic and grows on dead coniferous wood. Basidiocarps are gelatinous, bright orange, and extremely variable in shape, but typically stoutly stipe (mycology), stipitate with a spoon- or cup-shaped, spore-bearing head. They are frequently erumpent in groups, often coalescing to form complex masses up to across. ''Dacrymyces chrysospermus'' was originally described from New England, but is said to have a worldwide distribution. Microscopically it is distinguished from most other species of ''Dacrymyces'' by its comparatively large (18–23 by 6.5–8 micrometre, µm), 7-septum, septate basidiospores.

Peniophora
''Peniophora'' is a genus of fungus, fungi which are plant pathogens. Members of the genus belong to the class Agaricomycetes, order Russulales, and family Peniophoraceae. The genus is widespread, and contains 62 species. The species of ''Peniophora'' are resupination, resupinate, or crust-like, and are described as corticioid. A number of its members are parasite, parasitised by other fungi. For example, ''Tremella mesenterica'' is a parasite to several species of ''Peniophora''. Taxonomy and classification The genus was first described by Mordecai Cubitt Cooke in 1879. The type species is ''Peniophora quercina'', initially named ''Thelephora quercina'' by Christian Hendrik Persoon in 1801 before being transferred to ''Peniophora'' by Cooke in 1879. However, this species was also chosen as the type species for the genus ''Corticium (fungus), Corticium'' as defined by Persoon in 1794. Until 1981 the starting point for the binomial nomenclature, nomenclature of the corticioid fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tremella Mesenterica
''Tremella mesenterica'' ( common names include yellow brain, golden jelly fungus, yellow trembler, and witches' butter) is a common jelly fungus in the family Tremellaceae of the Agaricomycotina. It is most frequently found on dead but attached and on recently fallen branches, especially of angiosperms, as a parasite of wood decay fungi in the genus ''Peniophora''. The gelatinous, orange-yellow fruit body of the fungus, which can grow up to diameter, has a convoluted or lobed surface that is greasy or slimy when damp. It grows in crevices in bark, appearing during rainy weather. Within a few days after rain it dries into a thin film or shriveled mass capable of reviving after subsequent rain. This fungus occurs widely in deciduous and mixed forests and is widely distributed in temperate and tropical regions that include Africa, Asia, Australia, Europe, North and South America. Although considered bland and flavorless, the fungus is edible. ''Tremella mesenterica'' produces ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yeast
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species. Yeasts are unicellular organisms that evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae. Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 µm in diameter, although some yeasts can grow to 40 µm in size. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other conditions) are ca ...

Basidiospores
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 ...

Micrometre
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 Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate.
