Peltigera Horizontalis
''Peltigera horizontalis'' is a species of lichen in the family Peltigeraceae. It was first described by British botanist William Hudson in 1762 as ''Lichen horizontalis''. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus ''Peltigera ''Peltigera'' is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae.

Peltigera
''Peltigera'' is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. Commonly known as the dog or pelt lichens, species of ''Peltigera'' are often terricolous (growing on soil), but can also occur on moss, trees, rocks, and many other in many parts of the world. Most species of ''Peltigera'' have the cyanobacterium ''Nostoc'' as the dominant photobiont but some have the algae '' Coccomyxa.'' The presence of both a green alga and a cyanobacterium makes some tripartite; in this case they show cephalodium growths containing the third partner, ''Nostoc''. Because of their ability to fix nitrogen from the atmosphere, such lichens are influential in soil composition and generation. Description Species of ''Peltigera'' are foliose, with broad lobed thalli. Although the size of the thalli is variable and species-dependent, in some species the thalli can grow quite large, up to 30 cm in diameter.Vitikainen O. (1994). (1998). Taxonomic notes on n ...

Lichens Of North America
Irwin Murray Brodo (born November 7, 1935 in New York City) is an emeritus scientist at the Canadian Museum of Nature, in Ottawa, Ontario, Canada. He is an authority on the identification and biology of lichens. Early life and education Brodo grew up in the Bronx and attended City College in Manhattan as an undergraduate. He went on to do his graduate studies at Columbia University, and received a master's degree from Cornell University. He earned a Ph.D. in lichenology under the supervision of Henry Imshaug at Michigan State University. Career and research In 1965, Brodo was hired by the National Museum of Canada (now the Canadian Museum of Nature), where he continues to work as a research scientist emeritus. Over his career, he has built the lichen collection (CANL) into one of the best in North America. His research includes in-depth studies on challenging genera such as ''Bryoria'', ''Lecanora'', and ''Ochrolechia''. His 1968 work on the lichens of Long Island and the ef ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (Binomial nomenclature, scientific names) in the fungus Kingdom (biology), kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research New Zealand Limited, Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate Correct name (botany), correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page, a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of Synonym (taxonomy), synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized b ...

Johann Christian Gottlob Baumgarten
Johann Christian Gottlob Baumgarten (7 April 1765 – 29 December 1843) was a German physician and botanist who was a native of Luckau (Niederlausitz), Luckau in Lower Lusatia. He studied at the medical-surgical college in Dresden and at the University of Leipzig (from 1785), where he was a student of Johann Ehrenfried Pohl. While at Leipzig he performed field studies of its local flora, publishing the treatise "''Flora Lipsiensis''" in 1790. The same year he earned his philosophy degree, and in 1791 received his medical doctorate. Afterwards he furthered his studies of botany and medicine in Vienna. In 1793 he travelled to Transylvania, where he undertook pioneer investigations of its flora. In 1794, he was named district medical officer in Nocrich, Leschkirch, and from 1801, performed a similar role in Schäßburg (today known as Sighişoara, Romania). From 1807 onward, he devoted all his time and energy to botanical research in Transylvania. In 1816, he published the first of a ...

William Hudson (botanist)
William Hudson Fellow of the Royal Society, FRS (1730 in Kendal – 23 May 1793) was a British botanist and apothecary based in London. His main work was ''Flora Anglica'', published in 1762. He was elected a fellow of the Royal Society in 1761. Life and work Hudson was born between 1730 and 1732 at the White Lion Inn, Kendal, which was kept by his father. He was educated at Kirkbie Kendal School, Kendal grammar school, Hudson was subsequently apprenticed to an apothecary in London. He obtained the prize for botany given by the Apothecaries' Company which was a copy of John Ray, Ray's ''Synopsis''. However, he also paid attention to mollusca and insects and in Thomas Pennant, Pennant's ''British Zoology'' he is mentioned as the discoverer of ''Trochus terrestris''. From 1757 to 1768 Hudson was resident sub-librarian of the British Museum, and his studies in the Chelsea Physic Garden, Sloane herbarium enabled him to adapt the Linnean nomenclature to the plants described by Ray ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
