Perenniporia Celtis
''Perenniporia'' is a cosmopolitan genus of bracket-forming or crust-like polypores in the family Polyporaceae. They are dimitic or trimitic with smooth, thick-walled basidiospores and cause a white rot in affected wood. Taxonomy ''Perenniporia'' was proposed by American mycologist William Alphonso Murrill in 1943 to contain two species formerly placed in ''Poria'', a genus formerly used to contain all crust-like poroid fungi. His description of the genus was: "Hymenophore become perennial, riding; context white or yellow; tubes pinkish, white or yellow, stratose in older specimens; spores hyaline." Murrill's concept was to move the species with annual fruit bodies (''Poria unita'' and ''Poria nigriscens'') into ''Perenniporia'', retaining ''Poria'' for those that produced perennial fruit bodies. The genus name combines the Latin word ''perennis'' ("perennial") with the genus name ''Poria Edalat''. Murrill's designated type species, ''P. unita'', had a broad and ...

William Murrill
William Alphonso Murrill (October 13, 1869 – December 25, 1957) was an American mycologist, known for his contributions to the knowledge of the Agaricales and Polyporaceae. In 1904, he became the assistant Curator at the New York Botanical Garden (NYBG). He, along with the NYBG, founded the journal ''Mycologia'' and was its first editor for 16 years. Murrill was known to travel extensively to describe the mycota of Europe and the Americas. He traveled along the East Coast, Pacific Coast, Mexico and the Caribbean. Although Murrill was a very influential person at the NYBG, having worked his way up to become assistant director in 1908, his rather eccentric personality caused problems with his job. He went on annual collecting trips to Mexico, the Caribbean, Europe, and South America, sometimes, without informing any of his colleagues prior. These trips resulted in a cumulative total of 70,000 specimens, 1,400 of which are deposited in the NYBG.William Alphonso Murrill Records. ( ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perenniporia Subacida (19439027311)
''Perenniporia subacida'' is a species of poroid fungus in the family Polyporaceae. It is a plant pathogen that infects Douglas firs. The fungus was originally described in 1885 by American mycologist Charles Horton Peck. Marinus Anton Donk transferred it to the genus ''Perenniporia'' in 1967. The four varieties of this fungus originally proposed by Peck, namely ''Polyporus subacidus'' var. ''stalactiticus'', ''P. subacidus'' var. ''tenuis'', ''P. subacidus'' var. ''tuberculosus'' and ''P. subacidus'' var. ''vesiculosus'', have been shown to be synonyms A synonym is a word, morpheme, or phrase that means exactly or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are all .... The species is inedible.

Molecular Phylogenetic
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 determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Truncospora
''Truncospora'' is a genus of 10 species of fungi in the family Polyporaceae. Taxonomy The genus was originally proposed by Czech mycologist Albert Pilát in 1941, but this publication is invalid because a type species was not designated, contrary to the rules of botanical nomenclature. He published the genus validly in 1953 with two species: ''Truncospora oboensis'', and the type, ''T. ochroleuca''. Leif Ryvarden placed the genus in synonymy with ''Perenniporia'' in 1972, but molecular studies have shown that ''Truncospora'' is distinct genetically, and comprises part of the "core polyporoid clade", a grouping of fungi roughly equivalent to the family Polyporaceae. The generic name ''Truncospora'' is derived from the Latin ''trunco'' ("I cut off") and the Ancient Greek ("spore"). Description ''Truncospora'' is characterized by relatively small, cap-forming fruit bodies that generally measure about long, wide, and thick. The skeletal hyphae range from non-dextrinoid t ...

Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as “''nom. re ...

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
