Buellia Lobata
''Buellia lobata'' is a species of terricolous (soil-dwelling) lichen in the family Caliciaceae. Found in Australia, it was formally described as a new species in 2001 by lichenologists Ulrike Trinkaus and John Elix. The type specimen was collected in Blanchetown ( Murray Region, South Australia); here, in a parking area after the bridge, on the east side of the Murray River, the lichen was found growing on soil. It has also been recorded from Western Australia. The lichen occurs on calcareous soil in mallee, often with other terricolous lichens including species of ''Endocarpon'', '' Toninia'', '' Eremastriella crystallifera'', ''Fulgensia bracteata'', and '' Psora decipiens''. Secondary compounds that occur in the lichen include arthothelin and thuringione as major components, and minor amounts of 4,5-dichloronorlichexanthone and thiophanic acid. The species epithet ''lobata'' refers to the distinct lobes that comprise the thallus. See also * List of ''Buellia'' s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Lichens Described In 2001
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 . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |

Buellia
''Buellia'' is a genus of mostly lichen-forming fungi in the family Caliciaceae. The fungi are usually part of a crustose lichen. In this case, the lichen species is given the same name as the fungus. But members may also grow as parasites on lichens (lichenicolous). The algae in the lichen (the photobiont partner) is always a member of the genus ''Trebouxia''. Lichens in the genus are commonly called disc lichens, or button lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The genus has a widespread distribution and contains about 450 species. Genetic studies indicate that the genus ''Amandinea'' and ''Buellia'' may be the same,Scheidegger, C. 2009. Amandinea Choisy ex Scheid. & H. Mayrhofer (1993). In: C. W. Smith, A. Aptroot, B. J.

List Of Buellia Species
This is a list of species in the predominantly crustose lichen genus ''Buellia''. They are commonly known as "button lichens" due to the characteristic shape of their apothecia. A 2020 estimate placed about 300 species in the genus. , Species Fungorum accepts 201 species (including 9 varieties) in ''Buellia''.

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 was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
