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 (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichens consists of a 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 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 developed. :E.g. Genus '' Lecidea'' * Epi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pertusariaceae
The Pertusariaceae are a family of lichen-forming fungi in the order Pertusariales. Taxonomy The family was formally circumscribed by German lichenologist Gustav Wilhelm Körber in 1846. It contained the genera ''Pertusaria'' and '' Ochrolechia'' until ''Pertusaria'' was shown to be polyphyletic in a 2006 publication. The family Ochrolechiaceae was created to contain ''Ochrolechia''. Genera , Species Fungorum includes 6 genera and 379 species in the Pertusariaceae. *'' Lepra'' – 81 spp. *'' Loxosporopsis'' – 1 sp. *''Pertusaria'' – ca. 300 spp. *'' Phyllophiale'' – 1 sp. *'' Thamnochrolechia'' – 1 sp. *''Verseghya ''Verseghya'' is a genus of lichen-forming fungi in the family Pertusariaceae.

Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of . At the national level, after being ruled by three external powers since 1884, including nearly 60 years of Australian administration starting during World War I, Papua New Guinea established its sovereignty in 1975. It became an independent Commonwealth realm in 1975 with Elizabeth II as its queen. It also became a member of the Commonwealth of Nations in its own right.

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] |
Alan Archer
Alan W. Archer (born 1930) is a mycologist and taxonomist. He is currently (January 2021) an honorary research associate at Royal Botanic Gardens Sydney. He uses chemotaxonomy as well as morphological features in taxonomy and to devise keys, most recently for the genus ''Pertusaria'' in the Australasia region. During his career he has characterised and revised over 100 fungal taxa. He is an authority on the family Graphidaceae from the Australia - Pacific region and characterised ''Carbacanthographis salazinica'' and '' Phaeographis salazinica''. He was also the first to characterise several members of the genus ''Pertusaria'', '' Pertusaria ambigua'' '' Pertusaria epacrospora'', '' Pertusaria guineabissauensis'', ''Pertusaria salazinica ''Pertusaria salazinica'' is a species of crustose lichen in the family Pertusariaceae.

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the '' International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name '' Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type (biology)
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

Pertusaria
''Pertusaria'' is a large genus of warty crustose lichens in the Pertusariaceae family.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The fruiting bodies are usually modified apothecia that immersed in warts on the main body (thallus) with small holes for the spores to emerge, similar to ostioles, or are fully above and lecanorine (spore bearing discs surrounded by a ring of tissue similar to the tissue of the thallus. Members of the genus are commonly called wart lichens. The widespread genus contains over 500 species. Classification in the large genus relies heavily on thallus chemistry to distinguish and classify species, some of which differ only in the presence or absence of a single secondary chemical. Lichexanthone, norlichexanthone, and their chlorinated derivatives are common in this genus.
