Punctelia Subflava
''Punctelia subflava'' is a species of foliose lichen in the family Parmeliaceae that occurs in Australia. Taxonomy The lichen was first formally described in 1847 as ''Parmelia subflava'' by botanist Thomas Taylor. The type specimen, described from the herbarium collection of William Borrer, was collected on Tasmania (called Van Diemen's Land in the original publication). Taylor compared it to the common species '' Parmelia sulcata'', noting that it was smaller, and had neither a reticulated surface nor the retuse lobes (having an obtuse or rounded apex with a shallow notch) characteristic of that widespread species. John Elix and Jen Johnston transferred ''Parmelia subflava'' to the genus ''Punctelia'' in 1988. Several years earlier, David Galloway and Elix had proposed ''Parmelia subflava'' to be synonymous with '' Punctelia rudecta''. It is now known that ''Punctelia rudecta'' is a Northern Hemisphere species and does not occur in Australasia. Description Identical in ...

Thomas Taylor (botanist)
Thomas Taylor (1786–1848) was an Irish botanist, bryologist, and mycologist. Life Thomas Taylor, born on a boat on the Ganges, was the eldest son of Joseph Irwin Taylor, colonel in the East Indian army. He was educated at Trinity College, Dublin, graduating B.A. in 1807, and M.B. and M.D. in 1814. He was afterwards elected a fellow of the King and Queen's College of Physicians, and during his residence in Dublin acted as physician in ordinary to Sir Patrick Dun's Hospital. Geneva Sayre.

Synonym (biology)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia leva ...

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] |
Threatened Species Protection Act 1995
The ''Threatened Species Protection Act 1995'' (TSP Act), is an act of the Parliament of Tasmania that provides the statute relating to conservation of flora and fauna. Its long title is An Act to provide for the protection and management of threatened native flora and fauna and to enable and promote the conservation of native flora and fauna. It received the royal assent on 14 November 1995. As of 25 November 2020, the TSP Act is administered by the Department of Primary Industries, Parks, Water and Environment (Tasmania) and is the primary legislation for the listing, protection and conservation of threatened native flora and fauna in Tasmania. Threatened species in Tasmania can also be listed on the Environment Protection and Biodiversity Conservation Act 1999, which is the primary national legislation for the protection of threatened species in Australia. The objectives of the TSP Act are to ensure the survival of native flora and fauna as well to encourage, educate and as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lecanoric Acid
Lecanoric acid is a chemical produced by several species of lichen.ubChem - Lecanoric acid"> Lecanoric acid is classified as a polyphenol and a didepside and it functions as an antioxidant. The acid is named after the lichen ''Lecanora''. The acid has also been isolated from ''Usnea subvacata'', ''Parmotrema stuppuem'', ''Parmotrema tinctorum,'' '' Parmotrema grayana,'' Xanthoparmelia arida and Xanthoparmelia lecanorica. A related compound, 5-chlorolecanoric acid, is found in some species of ''Punctelia ''Punctelia'' is a genus of foliose lichens belonging to the large family Parmeliaceae.

Dorsiventral
A dorsiventral (Lat. ''dorsum'', "the back", ''venter'', "the belly") Organ (anatomy), organ is one that has two surfaces differing from each other in appearance and structure, as an ordinary leaf. This term has also been used as a synonym for dorsoventral organs, those that extend from a Dorsum (biology), dorsal to a ventral surface. This word is also used to define body structure of an organism, e.g. Platyhelminthes, flatworm have dorsiventrally flattened bodies. References Anatomy {{anatomy-stub ...

Isidia
An isidium is a vegetative reproductive structure present in some lichens. Isidia are outgrowths of the thallus surface, and are corticated (i.e., containing the outermost layer of the thallus), usually with a columnar structure, and consisting of both fungal hyphae (the mycobiont) and algal cells (the photobiont). They are fragile structures and may break off and be distributed by wind, animals, and splashing raindrops. In terms of structure, isidia may be described as warty, cylindrical, clavate (club-shaped), scale-like, coralloid (coral-shaped), simple, or branched. Examples of isidiate lichens include members of the genera ''Parmotrema'' and ''Peltigera''. See also Soredium Soredia are common reproductive structures of lichens. Lichens reproduce asexually by employing simple fragmentation and production of soredia and isidia. Soredia are powdery propagules composed of fungal hyphae wrapped around cyanobacteria o ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Thallus
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudocyphella
Pseudocyphellae (singular ''pseudocyphella'') are structures in lichens that appear as tiny pores on the outer surface (the cortex of the lichen. They are caused when there is a break in the cortex of the lichen, and the medullary hyphae extend to the surface. Pseudocyphellae are the same colour as the medulla of the lichen, which is generally white, but can be yellow in some species of ''Pseudocyphellaria'' and in ''Bryoria fremontii''. The presence/absence, abundance, colour, and shape of pseudocyphellae can all be diagnostic features used to identify different species. They facilitate gas exchange through the surface of the lichen, and may provide an adaptive advantage in temperate In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth.
