Hydnellum Underwoodii
''Hydnellum underwoodii'' is an inedible species of tooth fungus in the family Bankeraceae. Found in North America, it was described as new to science in 1906 by American mycologist Howard James Banker. Its reddish-brown, convex to flattened cap measures in diameter. Reddish-brown, partially erect scales adorn the cap surface. Spines on the cap underside are 1–3 mm long; they are initially white, becoming brown with grayish tips in age. The oval to spherical spores are 6–7.5 by 5.5–6.5 μm 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 Unit .... The fungus fruits singly or scattered, on the ground in coniferous forests.

Howard James Banker
Howard James Banker (April 19, 1866 – November 13, 1940) was an American mycology, mycologist. He received his PhD from Columbia University in 1908. Banker was an associate editor of the journal ''Mycologia'' starting from its establishment in 1909, until it became the official publication of the Mycological Society of America in 1933. He published several papers in the journal, including a revision of the North American Hydnaceae, which discussed 62 species in 10 genera. Banker died at his home in Huntington, New York, in 1940. The genus ''Bankera'' is named after him. Selected publications *Banker JH. 1902. A Historical Review of the Proposed Genera of the Hydnaceae.

Alessandro Trotter
Alessandro Trotter (26 July 1874 – 22 July 1967)) was an Italian botanist and entomologist who pioneered in cecidology, the study of plant galls. Biography Trotter's first work on cecidology dated back to 1897, and he reported 124 galls of which 21 were caused by eriophyid mites. Trotter travelled around Italy between 1899 and 1909 and described 742 galls in 20 papers. At the age of 28, he founded a journal called Marcella in honour of Marcello Malpighi which dealt with cecidology.Bernini, Fabio (2002) Acarid Phylogeny and Evolution: Adaptation in Mites and Ticks. Springer. pp. 7–8 He later became professor of plant pathology at the University of Naples and wrote more than 400 publications with nearly 110 on plant galls. He described several new species of Cynipidae and Cecidomyiidae some with Jean-Jacques Kieffer. Trotter was the son-in-law of Pier Andrea Saccardo Pier Andrea Saccardo (23 April 1845 in Treviso, Treviso – 12 February 1920 in ...

Tooth Fungus
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps (fruit bodies) producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus '' Hydnum'' ("hydnoid" means ''Hydnum''-like), but it is now known that not all hydnoid species are closely related. History ''Hydnum'' was one of the original genera created by Linnaeus in his ''Species Plantarum'' of 1753. It contained all species of fungi with fruit bodies bearing pendant, tooth-like projections. Subsequent authors described around 900 species in the genus. With increasing use of the microscope, it became clear that not all tooth fungi were closely related and most ''Hydnum'' species were gradually moved to other genera. The Dutch mycologist Rudolph Arnold Maas Geesteranus paid particular attention to the group, producing a series of papers reviewing the taxonomy of hydnoid fungi. The original genus ''Hydnum ...

Bankeraceae
The ''Bankeraceae'' are a family of fungi in the order Thelephorales. Taxa are terrestrial, and ectomycorrhizal with plant species in families such as Pinaceae or Fagaceae. The family was circumscribed by Marinus Anton Donk in 1961. According to a 2008 estimate, the family contains 6 genera and 98 species. Genera The family consists of the following genera: * ''Bankera'' * ''Boletopsis'' * ''Corneroporus'' * ''Hydnellum ''Hydnellum'' is a genus of tooth fungi in the family Bankeraceae (order Thelephorales).

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 the center of th ...

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] |
Coniferous Forest
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and 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 ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Described In 1906
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] |
