Godroniopsis
''Godroniopsis'' is a genus of fungi in the family Helotiaceae. The genus contains two species. The genus name of ''Godroniopsis'' is in honour of Dominique Alexandre Godron (1807–1880), who was a French physician, botanist, geologist and speleologist. The genus was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius.

Helotiaceae
The Helotiaceae are a family of fungi in the order Helotiales. The distribution of species in the family are widespread, and typically found in tropical areas. There are 117 genera and 826 species in the family. A question mark after the genus name means that according to the 2007 Outline of Ascomycota, the placement of that genus in this family is uncertain.

Dominique Alexandre Godron
Dominique Alexandre Godron (25 March 1807 - 16 August 1880) was a French physician, botanist, geologist and speleologist born in the town of Hayange, in the ''département'' Moselle. Godron studied medicine at the University of Strasbourg, and during his career distinguished himself in natural sciences as well as in the field of medicine. In 1854 he became dean and professor of natural history to the Faculty of Sciences at Nancy. Here he established a natural history museum and reorganized its botanical garden (now the '' Jardin Dominique Alexandre Godron'', renamed in his honor). Among his numerous writings were a publication on the flora of the Lorraine region of France called "''Flore de Lorraine''" (1843), and the three-volume "''Flore de France''", a work on flora native to France and Corsica that was co-written with botanist Jean Charles Marie Grenier (1808-1875). In addition to his botanical works, he published a number of studies in the field of ethnology. Before Men ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a 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 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 organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speleologist
Speleology is the scientific study of caves and other karst features, as well as their make-up, structure, physical properties, history, life forms, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term ''speleology'' is also sometimes applied to the recreational activity of exploring caves, but this is more properly known as ''caving'', ''potholing'' (British English), or ''spelunking''. Speleology and caving are often connected, as the physical skills required for ''in situ'' study are the same. Speleology is a cross-disciplinary field that combines the knowledge of chemistry, biology, geology, physics, meteorology, and cartography to develop portraits of caves as complex, evolving systems. History Before modern speleology developed, John Beaumont wrote detailed descriptions of some Mendip caves in the 1680s. The term speleology was coined by Émile Rivière in 1890. Prior to the mid-nineteenth century the scientific valu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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 molecular phylogenetics ...

William Webster Diehl
William Webster Diehl (January 15, 1891 – 1978) was an American mycologist recognized for his work on grass pathogens, particularly in the genus ''Balansia''. Diehl was born in on January 15, 1891 in Logansport, Indiana to parents Edwin Randall Diehl and Mary Delilah Wyrick Diehl. The family moved to Ohio shortly after his birth and he attended grammar school in Dayton. He attended Miami University from 1910–1914 and received an MSc in botany from Iowa State College in 1915. He was briefly an instructor of botany and plant pathology with Clemson before joining the USDA where he worked from 1928 until his retirement in 1958. He was honoured in 1954, when '' Diehliomyces'' is a genus of fungi in the Ascomycota phylum, was named after him.

Edith Katherine Cash
Edith Katherine Cash (October 14, 1890 – April 6, 1992) was an American Mycology, mycologist and Lichenology, lichenologist. Early life Edith Cash was born in Binghamton, New York, to John Ferris Cash and Adella Knapp Cash. She graduated from George Washington University in 1912 with an AB degree in history and languages and was the recipient of the Thomas F. Walsh undergraduate prize for academic excellence. She was knowledgeable about European literature, and according to the catalog from George Washington University, her major was in French with a minor in French and English. She studied as an assistant only one-night weekly during six months (October 1921 to May 1922) to obtain her formal mycology training, at the Graduate School USA, USDA Graduate School. She spent her entire research career in this institution. Cash started as a botanical translator in 1913. After 11 years, she advanced from that position to junior pathologist (1924). She obtained the position as assistant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
