Phaeotremella Frondosa
''Phaeotremella frondosa'' (synonym ''Tremella frondosa'') is a species of fungus in the family Phaeotremellaceae producing brownish, frondose, gelatinous basidiocarps (fruit bodies). It is widespread in north temperate regions, and is parasitic on other species of fungi ('' Stereum'' spp.) that grow on dead attached and recently fallen branches of broadleaf trees. Taxonomy ''Tremella frondosa'' was first published in 1822 by Swedish mycologist Elias Magnus Fries. The species was not clearly distinguished from ''Tremella foliacea'' until molecular research, based on cladistic analysis of DNA sequences, showed that the name ''Tremella foliacea'' covered several similar but distinct species. ''Phaeotremella frondosa'' is the name adopted for the widespread species growing on broadleaf trees, whilst ''Phaeotremella foliacea'' is restricted to conifers. The epithet "frondosa" means "leafy", with reference to the shape of the fruit bodies. Description Fruit bodies are ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereum Hirsutum
''Stereum hirsutum'', also called false turkey tail and hairy curtain crust, is a fungus typically forming multiple brackets on dead wood. It is also a plant pathogen infecting peach trees. ''S. hirsutum'' is in turn parasitised by certain other species such as the fungus ''Tremella aurantia''. Substrates for ''S. hirsutum'' include dead limbs and trunks of both hardwoods and conifers.USDA. 200USDA Fungal Database: ''Stereum hirsutum database''/ref> The cap is 1–4 cm wide. The spores are white. It is inedible.

Specific Name (botany)
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Of Asia
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'' (''true fungi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tremellomycetes
The Tremellomycetes are a class of dimorphic fungi in the Agaricomycotina. Some species have gelatinous basidiocarps (fruiting bodies) or (microscopically) a sacculate parenthesome. There are six orders, 17 families, and 39 genera in the Tremellomycetes. Tremellomycetes include yeasts, dimorphic taxa, and species that form complex fruiting bodies. Tremellomycetes include some fungi that are human and animal pathogens in the genera ''Cryptococcus'', ''Naganishia'', ''Papiliotrema'', and ''Trichosporon'' and some fungi that are cultivated for food in the genera ''Tremella'' and ''Naematelia ''Naematelia'' is a genus of fungi in the family Naemateliaceae.

Tremella Foliacea
''Phaeotremella foliacea'' (synonym ''Tremella foliacea'') is a species of fungus in the family Phaeotremellaceae. It produces brownish, frondose, gelatinous basidiocarps (fruit bodies) and is parasitic on the mycelium of '' Stereum sanguinolentum'', a fungus that grows on dead attached and recently fallen branches of conifers. It is widespread in north temperate regions. In the UK it has the recommended English name leafy brain and has also been called jelly leaf and brown witch's butter. Prior to 2017, the name ''Tremella foliacea'' was also applied to similar-looking species on broadleaf trees, now distinguished as '' Phaeotremella frondosa'' and ''Phaeotremella fimbriata''. Taxonomy ''Tremella foliacea'' was first published in 1800 by South African-born mycologist Christiaan Hendrik Persoon. The name remained in use until molecular research, based on cladistic analysis of DNA sequences, showed that ''Tremella foliacea'' was not closely related to the type species of ''Tre ...

Stereum Rugosum
''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 d ...

Stereum Sanguinolentum
''Stereum sanguinolentum'' is a species of fungus in the Stereaceae family. A plant pathogen, it causes red heart rot, a red discoloration on conifers, particularly spruces or Douglas-firs. Fruit bodies are produced on dead wood, or sometimes on dead branches of living trees. They are a thin leathery crust of the wood surface. Fresh fruit bodies will bleed a red-colored juice if injured, reflected in the common names bleeding Stereum or the bleeding conifer parchment. It can be the host of the parasitic jelly fungus '' Tremella encephala''. Taxonomy The species was first described scientifically by Albertini and Schweinitz in 1805 as ''Thelephora sanguinolenta''. Other genera to which it has been transferred throughout its taxonomical history include ''Phlebomorpha'', ''Auricularia'', ''Merulius'', and ''Haematostereum''. The fungus is commonly known as the "bleeding Stereum" or the "bleeding conifer parchment". Description The fruit body of ''Stereum sanguinolentum'' manifest ...

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] |
Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multice ...
