Pseudoplectania Vogesiaca
''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'', ''Plectan ...

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] |
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 ...

Sessility (botany)
In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts (such as flowers and leaves) that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (flower stalk). A flower that is not sessile is pedicellate. For example, the genus ''Trillium'' is partitioned into two subgenera, the sessile-flowered trilliums (''Trillium'' subg. ''Sessilium'') and the pedicellate-flowered trilliums. Sessile leaves lack petioles (leaf stalks). A leaf that is not sessile is petiolate. For example, the leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel Pedicle or pedicel may refer to: Human anatomy *Pedicle of vertebral arch, the segment between the transvers ...

Ascocarp
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plectania 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.< ...

Sarcosoma
''Sarcosoma'' is a genus of fungi in the family Sarcosomataceae. The genus, widespread in north temperate and tropical areas, contains 16 species. The anamorph (asexual) form is the genus '' Verticicladium''. Ecology and habitat The type species for the genus, ''Sarcosoma globosum'', occurs in temperate regions and typically inhabits flooded soil and areas in connection to rivers and brooks.Ohenoja, E., Kaukonen, M. and Ruotsalainen, A.L., 2013.

Urnula
''Urnula'' is a genus of cup fungi in the family Sarcosomataceae, circumscribed by Elias Magnus Fries in 1849. The genus contains several species found in Asia, Europe, Greenland, and North America. Sarcosomataceae fungi produce dark-colored (brown to black), shallow to deep funnel-shaped fruitbodies with or without a stipe, growing in spring. The type species of the genus is ''Urnula craterium'', commonly known as the devil's urn or the gray urn. ''Urnula'' species can grow as saprobes or parasites having an anamorphic state. The anamorphic form of ''U. craterium'' causes Strumella canker, on oak trees. Taxonomy Elias Magnus Fries circumscribed the new genus ''Urnula'' in 1849, and set what was then known as ''Peziza craterium'' as the type species. The genus name means "little urn"; the specific epithet is derived from the Latin '' cratera'', referring to a type of bowl used in antiquity. Description Imperfect states The life cycle of ''Urnula craterium'' allows for bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galiella
''Galiella'' is a genus of fungi in the family Sarcosomataceae. The genus is widely distributed in northern temperate regions, and according to one estimate, contains eight species. Taxonomy ''Galiella'' was described in 1957 by Richard Korf and John Axel Nannfeldt. In the early 1950s, French mycologist Marcelle Louise Fernande Le Gal used the generic name ''Sarcosoma'' to treat several species that she did not think belonged in the same genus as ''Sarcosoma globosum'', the type species. As Korf later pointed out, this usage contravened the rules of botanical nomenclature. Korf and Nannfield proposed ''Galiella'' to accommodate these species, and set '' G. rufa'' as the type. The generic name honors French mycologist Marcelle Louise Fernande Le Gal. Description ''Galiella'' includes bulgarioid species (those with a morphology similar to those in ''Bulgaria'') with spores featuring surface warts that are made of callose-pectic substances that stain with methyl blue Met ...

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

Ribosomal RNA
Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes. Ribosomal RNA is transcribed from ribosomal DNA (rDNA) and then bound to ribosomal proteins to form SSU rRNA, small and LSU rRNA, large ribosome subunits. rRNA is the physical and mechanical factor of the ribosome that forces transfer RNA (tRNA) and messenger RNA (mRNA) to process and Translation (biology), translate the latter into proteins. Ribosomal RNA is the predominant form of RNA found in most cells; it makes up about 80% of cellular RNA despite never being translated into proteins itself. Ribosomes are composed of approximately 60% rRNA and 40% ribosomal proteins by mass. Structure Although the primary structure of rRNA sequences can vary across organisms, Base pair, base-pairing within these sequences commonly forms stem-loop configurations.
