Pseudoplectania Nigrella
''Pseudoplectania nigrella'', commonly known as the ebony cup, the black false plectania, or the hairy black cup, is a species of fungi in the family Sarcosomataceae. The fruit bodies of this saprobic fungus are small blackish cups, typically up to broad, that grow in groups on soil, often amongst pine needles and short grass near coniferous trees. ''Pseudoplectania nigrella'' has a worldwide distribution, and has been found in North America, the Caribbean, Britain, Europe, India, Madagascar, New Zealand, and Japan. The fungus produces a unique chemical compound, plectasin, that has attracted research interest for its ability to inhibit the growth of the common human pathogenic bacterium ''Streptococcus pneumoniae''. Taxonomy and naming Christian Hendrik Persoon named the species ''Peziza nigrella'' in his ''Systema Mycologia'' in 1801, and it was sanctioned under this name in Elias Magnus Fries' ''Systema Mycologicum'' in 1821. In 1870, German mycologist Fuckel transferred it t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a German mycologist who made additions to Linnaeus' mushroom taxonomy. Early life Persoon was born in South Africa at the Cape of Good Hope, the third child of an immigrant Pomeranian father and Dutch mother. His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Education Initially studying theology at Halle, at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen. He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. Later years He moved to Paris in 1802, where he spent the rest of his life, renting an upper floor of a house in a poor part of town. He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to do ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Pseudoplectania Milleri
''Pseudoplectania'' is a genus of fungi in the family Sarcosomataceae. The genus contains 12 species. ''Pseudoplectania ryvardenii'' was described in 2012, while ''Pseudoplectania carranzae'' was transferred to the genus (from ''Plectania'') in 2013. Taxonomy The genus was circumscribed by the German botanist Fuckel in 1870, who originally included the two species ''P. nigrella'' and ''P. fulgens''. The latter species was removed from the genus by Pier Andrea Saccardo in 1889, and made the type species of his newly created genus ''Otidella'' (now considered synonymous with ''Caloscypha'' as described by Boudier in 1885; ''P. fulgens'' is now '' Caloscypha fulgens''). Saccardo added the species ''P. melania'' and ''P. stygia'', the latter of which is thought to be synonymous with ''P. nigrella.'' Phylogenetic analysis based on the DNA sequences of ribosomal RNA suggests that ''Pseudoplectania'' groups in a clade together with ''Galiella'', ''Ple ...

Plectania Melastoma in 1870.
''Plectania'' is a genus of fungi in the family Sarcosomataceae. There are 15 species in the genus, which have a widespread distribution, especially in northern temperate areas. ''Plectania'' was circumscribed by German botanist Karl Wilhelm Gottlieb Leopold Fuckel Karl Wilhelm Gottlieb Leopold Fuckel (3 February 1821 – 8 May 1876) was a German botanist who worked largely on fungi. He worked as an apothecary from 1836 to 1852, afterwards deriving income from a vineyard he owned in Oestrich im Rheingau.< ...

Sphagnum Moss
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and ericaceous shrubs, as well as orchids and carnivorous plants.Keddy, P ...

Paraphyses
Paraphyses are erect sterile filament-like support structures occurring among the reproductive apparatuses of fungi, ferns, bryophytes and some thallophytes. The singular form of the word is paraphysis. In certain fungi, they are part of the fertile spore-bearing layer. More specifically, paraphyses are sterile filamentous hyphal end cells composing part of the hymenium of Ascomycota and Basidiomycota interspersed among either the asci or basidia respectively, and not sufficiently differentiated to be called cystidia A cystidium (plural cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that ar ..., which are specialized, swollen, often protruding cells. The tips of paraphyses may contain the pigments which colour the hymenium. In ferns and mosses, they are filament-like structures that are found on sporangia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from el, ὑάλινος, translit=hyálinos, lit=transparent, and el, ὕαλος, translit=hýalos, lit=crystal, glass, label=none. Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining. Ichthyology and entomology In ichthyology and entomology, ''hyaline'' denotes a colorless, transparent substance, such as unpigmented fins of fishes or clear insect wings. Resh, Vincent H. and R. T. Cardé, Eds. Encyclo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascospore
An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. ''Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. ''Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some ''Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bourrelet ...

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] |
