Parmeliaceae
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: '' Xanthoparmelia'' ( 822 species), ''Usnea'' (355 species), ''Parmotrema'' ( 255 species), and ''Hypotrachyna'' (262 species). Nearly all members of the family have a symbiotic association with a green alga (most often ''Trebouxia'' spp., but '' Asterochloris'' spp. are known to associate with some species).Miadlikowska, J.

Sulcaria Spiralifera
''Sulcaria spiralifera'' is a species of fruticose lichen in the family Parmeliaceae. It is found in the northwestern United States, where it grows as an epiphyte, hanging from a variety of tree species in open or shaded maritime forests. Taxonomy The species was first formally described in 1977 by lichenologists Irwin Brodo and David Hawskworth as a species of '' Bryoria''. It was transferred to the genus ''Sulcaria'' in 2014 by Leena Myllys, Saara Velmala, and Trevor Goward. Using DNA analysis and molecular phylogenetics, they also determined that ''Bryoria pseudocapillaris'', another taxon described by Brodo and Hawskworth in 1977, was actually the same species as ''Sulcaria spiralifera'', and placed the former taxon in synonymy with the latter. Description The thallus of ''Sulcaria spiralifera'' usually hangs in a more or less fashion, extending from in length. Displaying colours ranging from pale to dark brown, the exterior can either be dull or exhibit a subtle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jan Bystrek
Jan Bystrek (17 June 1934 – 20 February 2020) was a Polish botanist and professor of natural sciences. He was employed at the Department of Systematic and Geography of Plants at the Maria Curie-Skłodowska University from 1956 until 2004. He published research in many fields, including botany, floristry, lichenology, systematics, environmental protection, biogeography, ecology, bioindication, and nature and landscape protection. He was involved in popularizing knowledge about nature and ecological education. Education Jan Bystrek was born in Grodzany on 17 June 1934. In 1951 Bystrek graduated from the secondary school in Bychawa. After graduating from high school, he started studies in Kraków at the AGH University of Science and Technology, which he had to leave after two months for financial reasons. He started working at the Municipal self-help Cooperative in Bychawa. In the years 1952 to 1957 he studied at the Maria Curie-Skłodowska University (UMCS) in Lublin ...

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 ...

Fruticose Lichen
A fruticose lichen is a form of lichen fungi that is characterized by a coral-like shrubby or bushy growth structure. It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts. Fruticose lichens are not a monophyletic and holophyletic lineage, but is a form encountered in many classes. Fruticose lichens have a complex vegetation structure, and are characterized by an ascending, bushy or pendulous appearance. As with other lichens, many fruticose lichens can endure high degrees of desiccation. They grow slowly and often occur in habitats such as on tree barks, on rock surfaces and on soils in the Arctic and mountain regions. Characteristics Fruticose lichens are lichens composed of a shrubby or bushy thallus and a holdfast. The thallus is the vegetative body of a lichen that does not have true leaves, stems, or roots. The thallus colour is affected by the algae in the lichen, compounds created by t ... [...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 ...

Lichen Genera
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 .
