Pulchrocladia Corallaizon
''Pulchrocladia corallaizon'' is a species of lichen in the family Cladoniaceae. It was first formally described as ''Cladia corallaizon''. The specific epithet ''corallaizon'', modified from Greek, means "ever-living coral". In 2018, it was transferred to the newly circumscribed genus ''Pulchrocladia''. The lichen makes pale grey to greenish-grey pseudopodetia that are up to tall. Secondary compounds occurring in the lichen include atranorin, protolichesterinic acid, ursolic acid, and usnic acid. The distribution of ''Pulchrocladia corallaizon'' is limited to South Australia and Western Australia Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to th ....

Rex Bertram Filson
Rex Bertram Filson (born 1930) is an Australian lichenologist who made major contributions to knowledge of lichens in Australia and Antarctica. Early in his career Filson worked as a carpenter in various places around Australia, and from 1961 to 1963 was employed as a carpenter by the Australian Antarctic Division. This was the start of his career as a lichenologist. In 1964, he was employed by the Royal Botanic Gardens. Employment with the Victorian Department of Crown Lands and Survey followed (1964–1988), first as a seed-collector and finally as senior botanist. During this period, he acquired a Master of Science (1979) and a Doctor of Science (1988) from Monash University. In 1970, Filson was awarded a Churchill Fellowship to compare northern hemisphere with Australian lichens. The National Herbarium of Victoria holds the majority of Filson's collections, over 15,000 specimens, with duplicates distributed around Australian Herbaria including AD, BRI, CANB, HO, NSW and ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with 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 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 synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''. Current names in ''Index Fungorum'' (''Specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

Usnic Acid
Usnic acid is a naturally occurring dibenzofuran derivative found in several lichen species with the formula C18H16O7. It was first isolated by German scientist W. Knop in 1844 and first synthesized between 1933-1937 by Curd and Robertson. Usnic acid was identified in many genera of lichens including ''Usnea'', '' Cladonia'', ''Hypotrachyna'', ''Lecanora'', ''Ramalina'', '' Evernia'', ''Parmelia'' and '' Alectoria''. Although it is generally believed that usnic acid is exclusively restricted to lichens, in a few unconfirmed isolated cases the compound was found in kombucha tea and non-lichenized ascomycetes. At normal conditions, usnic acid is a bitter, yellow, solid substance. It is known to occur in nature in both the d- and l-forms as well as a racemic mixture. Salts of usnic acid are called usnates (e.g. copper usnate). Biological role in lichens Usnic acid is a secondary metabolite in lichens whose role has not been completely elucidated. It is believed that usnic acid prote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ursolic Acid
Ursolic acid (sometimes referred to as urson, prunol, malol, or 3β-hydroxyurs-12-en-28-oic acid), is a pentacyclic triterpenoid identified in the epicuticular waxes of apples as early as 1920 and widely found in the peels of fruits, as well as in herbs and spices like rosemary and thyme. Natural occurrence Ursolic acid is present in many plants, such as ''Mirabilis jalapa'', as well as in many fruits and herbs used in daily life (e.g. apples, basil and holy basil, bilberries, cranberries, elder flower, peppermint, rosemary, lavender, oregano, thyme, hawthorn, and prunes). Apple peels contain large quantities of ursolic acid and related compounds. Potential biochemical effects A number of potential biochemical effects of ursolic acid have been investigated, but there has been no clinical study demonstrating benefits to human health. ''In vitro'', ursolic acid inhibits the proliferation of various cancer cell types by inhibiting the STAT3 activation pathway, and may also d ...

Secondary Metabolite
Secondary metabolites, also called specialised metabolites, toxins, secondary products, or natural products, are organic compounds produced by any lifeform, e.g. bacteria, fungi, animals, or plants, which are not directly involved in the normal growth, development, or reproduction of the organism. Instead, they generally mediate ecological interactions, which may produce a selective advantage for the organism by increasing its survivability or fecundity. Specific secondary metabolites are often restricted to a narrow set of species within a phylogenetic group. Secondary metabolites often play an important role in plant defense against herbivory and other interspecies defenses. Humans use secondary metabolites as medicines, flavourings, pigments, and recreational drugs. The term secondary metabolite was first coined by Albrecht Kossel, a 1910 Nobel Prize laureate for medicine and physiology in 1910. 30 years later a Polish botanist Friedrich Czapek described secondary metabolit ...

Teuvo Ahti
Teuvo ("Ted") Tapio Ahti (born 1934) is a Finnish botanist and lichenologist. He has had a long career at the University of Helsinki that started in 1963, and then following his retirement in 1997, at the Botanical Museum of the Finnish Museum of Natural History. Known as a specialist of the lichen family Cladoniaceae, Ahti has published more than 280 scientific publications. A ''Festschrift'' was dedicated to him in 1994, and in 2000 he was awarded the prestigious Acharius Medal for lifetime contributions to lichenology. Education and career Ahti started developing an interest in botany at the age of 15, when he worked on a class project involving collecting 100 species of plants. His attention turned to lichens when a classmate who had worked for Veli Räsänen pointed them out during a birdwatching excursion in Helsinki. His interest was further fuelled when a couple of years later, he had to pass a test on identification of forest floor lichens and bryophytes as part of an ...
