Amandinea Decedens
''Amandinea decedens'' is a crustose lichen in the family Caliciaceae, first described as ''Lecidea decedens'' by Finnish botanist William Nylander in 1869. It was assigned (invalidly) the name, ''Amandinea decedens,'' in 2002 by Juliane Blaha and Helmut Mayrhofer. The name was validly published in 2016 by Blaha, Mayrhofer and Jack Elix On coastal rocks, when it is found, it is abundant.

William Nylander (botanist)
William (Wilhem) Nylander (3 January 1822 – 29 March 1899) was a Finnish botanist and entomologist. Nylander was born in Oulu, and taught at the University of Helsinki before moving to Paris, where he lived until his death in 1899. Nylander studied medicine, receiving a degree in 1847. Nylander pioneered the technique of determining the taxonomy of lichens by the use of chemical reagents, such as potassium hydroxide, tinctures of iodine and calcium hypochlorite, still used by lichenologists as the K and C tests. Nylander was the first to realise the effect of atmospheric pollution Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are many different types ... on the growth of lichens, an important discovery that paved the way for the use of lichens to detect pollution and determine the cleanness o ...

Helmut Mayrhofer
Helmut Mayrhofer is an Austrian lichenologist. He is known for his expertise on the lichen family Physciaceae and his studies of the lichen flora of the Balkan Peninsula, the Alps, and other regions. Biography Helmut Mayrhofer was born in 1953 in Aich, a village in Austria. He went to secondary school in Gröbming and Graz, and then to the University of Graz. He graduated from there in 1976 with a master's degree, having submitted a thesis titled "Flechten auf ''Rhododendron ferrugineum''" ("Lichens on '' Rhododendron ferrugineum''"). Mayrhofer worked at the as a high school teacher before returning to the University of Graz for work as a scientific assistant, a position he held until 1988. While working as a schoolteacher, Mayrhofer was also working on his doctoral degree, under the supervision of Josef Poelt. He defended his thesis, titled "Die saxicolen Arten der Flechtengattungen ''Rinodina'' und ''Rinodinella'' in der Alten Welt" ("The saxicolous species of the liche ...

John Alan Elix
John Alan (Jack) Elix (born 1941) emeritus professor in chemistry at the Australian National University, is an organic chemist who has contributed in many fields: lichenology, lichen chemotaxonomy, plant physiology and biodiversity and natural product chemistry. He has authored 2282 species names, and 67 genera in the field of mycology. Education His first degree, B.Sc., and his Ph.D were both in organic chemistry from the University of Adelaide. This was followed by post-doctoral years at the University of Cambridge and then a D.Sc. in natural products chemistry from the Australian National University. Career Elix spent a post doctoral year in 1966 at Cambridge, returning to Australia in 1967 to a lectureship in chemistry at the ANU. He retired as professor of chemistry in 2002, becoming professor emeritus. By 1975 he had already published several papers on the organic chemistry of lichens, and ultimately leading to work on the evolution, taxonomy and phylogeny of liche ...

Crustose Lichen
Crustose lichens are lichens that form a crust which strongly adheres to the Substrate (biology), substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichens consists of a cortex (botany), cortex layer, an algal layer, and a medulla. The upper cortex layer is differentiated and is usually pigmented. The algal layer lies beneath the cortex. The medulla fastens the lichen to the substrate and is made up of Fungus, fungal hyphae. The surface of crustose lichens is characterized by branching cracks that periodically close in response to climatic variations such as alternate wetting and drying regimes. Subtypes * Powdery – considered as the simplest subtype due to the absence of an organized thallus. :The thallus appears powdery. :E.g. Genera ''Lepraria'', ''Vezdaea'' * Endolithic – grows inside the rock, usually in interstitial spaces between mineral grains. The :upper cortex is usually d ...

Caliciaceae
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 36 genera and about 600 species. The largest genus is ''Buellia'', with around 300 species; there are more than a dozen genera that contain only a single species. Most Caliciaceae grow on bark, dead wood, or rocks. Some members of this family, particularly those of the type genus, ''Calicium'', are characterized by the presence of thin-walled and short-lasting asci (spore-bearing cells) and a mazaedium, which is an accumulation of loose, maturing spores covering the surface of the fruiting body. The resulting passive spore dispersal is relatively rare amongst the Ascomycota. The mazaedium, usually black, either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GBIF
The Global Biodiversity Information Facility (GBIF) is an international organisation that focuses on making scientific data on biodiversity available via the Internet using web services. The data are provided by many institutions from around the world; GBIF's information architecture makes these data accessible and searchable through a single portal. Data available through the GBIF portal are primarily distribution data on plants, animals, fungi, and microbes for the world, and scientific names data. The mission of the GBIF is to facilitate free and open access to biodiversity data worldwide to underpin sustainable development. Priorities, with an emphasis on promoting participation and working through partners, include mobilising biodiversity data, developing protocols and standards to ensure scientific integrity and interoperability, building an informatics architecture to allow the interlinking of diverse data types from disparate sources, promoting capacity building and catal ...
