Ingvariella
''Ingvariella'' is a lichen genus in the family Stictidaceae. Circumscribed in 1997, the genus is monotypic, containing the single widespread lichen species ''Ingvariella bispora''. The species was originally named ''Urceolaria bispora'' by Italian lichenologist Francesco Baglietto in 1871. ''Ingvariella'' is named in honour of Swedish lichenologist Ingvar Kärnefelt Jan Eric Ingvar Kärnefelt (born 1944) is a Swedish lichenologist.

Ingvar Kärnefelt
Jan Eric Ingvar Kärnefelt (born 1944) is a Swedish lichenologist. Early life and education Kärnefelt was born in Gothenburg, Sweden in 1944. His initial goal in his higher-level studies at University of Cologne in 1966–1967 was to become a dentist. He changed courses in 1968, turning instead to biology at the University of Gothenburg in 1968. Gunnar Degelius, his first teacher during undergraduate studies in botany in 1968, inspired him and others. After Degelius' retirement in 1969, Ingvar continued his studies at Lund University, where Hans Runemark held a position in systematic botany. In 1971 he met Ove Almborn, who became his supervisor. In 1979, he defended his thesis titled "The brown fruticose species of ''Cetraria''". The thesis was later awarded a prize for the best doctoral dissertation in botany at Lund University during a 5-year period by the Royal Physiographic Society in Lund. Career Kärnefelt became associate professor at the Department of Systematic Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lumbsch
Helge Thorsten Lumbsch (born 1964) is a German-born lichenologist living in the United States. His research interests include the phylogeny, taxonomy, and phylogeography of lichen-forming fungi; lichen diversity; lichen chemistry and chemotaxonomy. He is the Associate Curator and Head of Cryptogams and Chair of the Department of Botany at the Field Museum of Natural History. Biography Lumbsch was born in Frankfurt in 1964. Interested in lichens already as a schoolboy, he studied natural sciences at the University of Marburg, under the tutelage of Aino Henssen. He received his diploma in 1989, with a dissertation titled ''Ontogenetisch-systematische Studien der Trapeliaceae und verwandter Familien (Lichenisierte Ascomyceten)'' ("Ontogenic-systematic studies of the Trapeliaceae and related families (lichenized ascomycetes"). After Henssen's retirement in 1990, he transferred to the University in Essen, where he worked on the ''Lecanora subfusca'' group in Australasia, a subject t ...

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 ...

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 ...

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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Francesco Baglietto
Francesco Baglietto (2 September 1826 – 24 February 1916) was an Italian physician and botanist, known for his studies on cryptogams, particularly on lichens. Biography Francesco Baglietto was born in Voltri, Italy, on 2 September 1816. A pupil of Giuseppe De Notaris, Baglietto specialized in the study of lichens, a subject on which he left numerous publications. Together with de Notaris and Vincenzo de Cesati, they founded the (Italian Cryptogamic Society), which published the scientific journal, journal ''Commentario della Società crittogamologica italiana'' ("Commentary of the Italian Cryptogamic Society"). The society had the aim of creating and publishing the Italian cryptogamic herbarium, intended to be an all-encompassing collection of all types of cryptogams, including mosses, lichens, ferns, and mushrooms. Together with V. de Cesati and G. de Notaris, Baglietto published two series of the exsiccata work ''Erbario crittogamico Italiano'' with altogether 3000 numbered ...

Taxa Described In 1997
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
