Leprieuria
''Leprieuria'' is a genus of fungi in the family Xylariaceae. This is a monotypic genus, containing the single species ''Leprieuria bacillum''. The genus name of ''Leprieuria'' is in honour of François Mathias René Leprieur (1799–1870) who was a French pharmacist and naturalist. The genus was circumscribed In geometry, a circumscribed circle for a set of points is a circle passing through each of them. Such a circle is said to ''circumscribe'' the points or a polygon formed from them; such a polygon is said to be ''inscribed'' in the circle. * Circum ... by Thomas Læssøe, Jack David Rogers and Anthony James Seddon Whalley in Mycol.

Xylariaceae
The Xylariaceae are a family of mostly small ascomycetous fungi. It is one of the most commonly encountered groups of ascomycetes and is found throughout the temperate and tropical regions of the world. They are typically found on wood, seeds, fruits, or plant leaves, some even associated with insect nests. Most decay wood and many are plant pathogens. One example of this family is King Alfred's Cake ('' Daldinia concentrica''). Phylogenetic analyses published in 2009 suggest that there are two main lineages in this family, Hypoxyloideae and Xylarioideae. Genera This is a complete list of genera in the Xylariaceae, based on the 2007 Outline of Ascomycota. A question mark before the genus name indicates that the placement of that taxon in this family is uncertain.

François Mathias René Leprieur
François Mathias René Leprieur (18 April 1799, Saint-Dié-des-Vosges – 16 July 1870, Cayenne) was a French pharmacist and naturalist. Throughout his career, he collected specimens in the fields of entomology, ichthyology and botany.Expeditions & Surveys François René Mathias Leprieur (biography) Trained as a naval pharmacist, he was stationed in from 1824 to 1829. With botanist , he conducted exploratory investigations of the region. During a furlough in France in 1829, he began a botanical work based on his ...

Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (), a microscopic sexual reproduction, sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of Ascomycota are Asexual reproduction, asexual and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, yeast#Beer, brewers' and bakers' yeast, Xylaria, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (containing all of the descendants of a common ancestor). Previously placed in the Basidiomycota along with asexual species from other fungal taxa, asexual (or Teleomorph, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xylariales
The Xylariales are an order (biology), order of fungi within the class (biology), class Sordariomycetes (also known as Pyrenomycetes), subdivision Pezizomycotina, division (mycology), division Ascomycota. It was the original order of the Class (taxonomy), subclass Xylariomycetidae. Xylariales was circumscription (taxonomy), circumscribed in 1932 by Swedish mycologist John Axel Nannfeldt, and Xylariomycetidae by Ove Erik Eriksson and Katarina Winka in 1997. Taxonomy Early classifications of the Xylariales varied considerably, with taxonomists recognising anywhere from three to eleven family (biology), families within the order. A milestone in understanding the order's composition came from Smith, Liew, and Hyde's 2003 molecular phylogenetics study, which established the Xylariales as a monophyletic group containing seven families: Amphisphaeriaceae, Apiosporaceae, Clypeosphaeriaceae, Diatrypaceae, Graphostromataceae, Hyponectriaceae, and Xylariaceae. During this period, fungi in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. For example, if we determine that species X, Y, and Z belong in genus A, and species T, U, V, and W belong in genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecu ...
