Mason Hale
Mason Ellsworth Hale, Jr. (September 23, 1929 – April 23, 1990) was one of the most prolific lichenologists of the 20th century. Many of his scholarly articles focused on the taxonomy of the family Parmeliaceae. Hale was one of the first lichen experts to incorporate secondary chemistry and technology such as computers and scanning electron microscopy into taxonomic work. Mason Hale published approximately two hundred articles and books on various aspects of lichen biology including taxonomy, anatomy, chemistry, and ecology. Hale also wrote several books aimed at education and increasing accessibility to lichens. Early life and education Mason Hale Jr. grew up on a farm outside of Winsted, Connecticut. He had an affinity towards biology from experiences from living on his family's farm. As an undergraduate, Hale wanted to be a linguist, but was not able to take specialized classes. Instead, he earned an undergraduate degree studying biology at Yale University, where he studied ... [...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 ...

Lichen
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Graphidaceae
The Graphidaceae are a family of lichens in the order Ostropales. Distribution and ecology The vast majority of Graphidaceae species are restricted to the tropics. Most Graphidaceae species are epiphytic (i.e. they grow only on plants). Genera A recent (2020) estimates places 31 genera and about 990 species in Graphidaceae. The following list indicates the genus name, the taxonomic authority, year of publication, and the number of species: *'' Acanthothecis'' – 5 spp. *'' Acanthotrema'' – 1 sp. *'' Aggregatorygma'' – 1 sp. *'' Allographa'' – 183 spp. *'' Amazonotrema'' – 1 sp. *'' Ampliotrema'' – 1 sp. *'' Anomalographis'' – 2 spp. *'' Anomomorpha'' – 8 spp. *'' Astrochapsa'' – 29 spp. *'' Austrotrema'' – 3 spp. *'' Borinquenotrema'' – 1 sp. *'' Byssotrema'' – 1 sp. *'' Carbacanthographis'' – 22 spp. *'' Chapsa'' – 51 spp. *'' Chroodiscus'' – 17 spp. *'' Clandestinotrema'' – 17 spp. *'' Compositrema'' – 4 spp. *'' Corticorygma' ...

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 ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
