Loweomyces Fractipes
''Loweomyces fractipes'' is a species of polypore, poroid fungus in the family Steccherinaceae, and the type species of the genus ''Loweomyces''. It is a widely distributed species, found in North America, Europe, Central America, South America, and Korea. Taxonomy The fungus was originally species description, described in 1872 as ''Polypores fractipes'' by Miles Berkeley and Moses Ashley Curtis. The type specimens had been sent to Berkeley by American botanist Henry William Ravenel. It has been transferred to many different polypore genera in its taxonomic history. William Alphonso Murrill, William Murrill moved it to ''Grifola'' in 1904, while it was later transferred to ''Abortiporus'' (Bondartsev, 1959), ''Heteroporus'' (Fidalgo, 1969), and ''Spongipellis'' (Kotl., Kotlaba & Pouzar, 1976). In 1982, Walter Jülich transferred it to ''Loweomyces'', originally a subgenus of ''Spongipellis'' but elevated to generic status by Jülich. Heterotypic synonyms (having different type ( ...

Fungi
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), 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 motility, 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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry William Ravenel
Henry William Ravenel (May 19, 1814 – July 17, 1887) was an American planter and botanist. He studied fungi and cryptogams in South Carolina, discovering a large number of new species. The genus '' Ravenelia'' is named after him, along with many of the species he discovered. Biography Early life Henry William Ravenel was born on May 19, 1814 on the Pooshee Plantation in Berkeley County, South Carolina. The plantation had been in his family since before 1716. It now lies beneath the waters of Lake Moultrie, which was created in 1939. The nearest existing place is Bonneau. He attended the nearby Pineville Academy and graduated in 1832 from South Carolina College, now the University of South Carolina, where he was a member of the Clariosophic Society The Clariosophic Society, also known as ΜΣΦ (Mu Sigma Phi), is a literary society founded in 1806 at the University of South Carolina, then known as South Carolina College, as a result of the splitting in two of the Ph ...

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 ( ...

Hypha
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 membran ...

Loweomyces Fractipes 229111
''Loweomyces'' is a genus of six species of poroid fungi in the family Steccherinaceae (formerly placed in the Meruliaceae). Taxonomy It was originally circumscribed as a subgenus of ''Spongipellis'' by the Czech mycologists František Kotlaba and Zdeněk Pouzar in 1976. Swiss mycologist Walter Jülich promoted it to a genus segregate from ''Spongipellis'' in 1982, with two species: '' L. fractipes'' (the type), and '' L. wynneae''. Jülich thought the genus should be distinct from ''Spongipellis'' based on the larger basidia, the absence of skeletal hyphae, and smaller tubes. ''L. fractipes'' and ''L. wynneae'' have had their generic positions confirmed with molecular phylogenetics, and both group in the "residual polyploid clade", one of four main lineages of the Polyporales. The genus is named in honour of American mycologist and polypore specialist Josiah Lincoln Lowe. Description ''Loweomyces'' is distinguished by the ease of spore germination in growth ...

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 t ...

Pileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp ( fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium ( hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various '' Amanita'' species and boletes. Some, such as the parasol mushroom, have distinct bosses or umbos and are described as '' umbonate''. An umbo is a knobby protrusion at th ...

Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus or cortina) or unive ...

Basidiocarp
In fungi, a basidiocarp, basidiome, or basidioma () is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye (especially those with a more or less agaricoid morphology) are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles. Structure All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi. In more complex basidiocarps, there is differentiation into a stipe, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostyl ...

Spongipellis
''Spongipellis'' is a genus of fungi in the family Polyporaceae. The genus is widely distributed and contains ten species. The genus was circumscribed by French mycologist Narcisse Théophile Patouillard in 1887. The genus name combines the Latin words ''spongia'' ("sponge") and ''pellis'' ("skin").
