Flavoparmelia Soredians
''Flavoparmelia soredians'' is a widely distributed species of foliose lichen in the large family Parmeliaceae. In the late 1990s, an increase in the frequency of ''Flavoparmelia soredians'' was noted in the Netherlands, which, until then, occurred rarely in the country. This population increase followed a decrease in the levels of the pollutant sulphur dioxide. '' Punctelia borreri'' and '' Flavoparmelia caperata'' were two other foliose species that experienced a similar increase in regional frequency during this time. Taxonomy The lichen was first formally described by Finnish lichenologist William Nylander in 1872 as ''Parmelia soredians''. Mason Hale Mason Ellsworth Hale, Jr. (September 23, 1929 – April 23, 1990) was one of the most prolific lichenologists of the 20th century. Many of his scholarly articles focused on the taxonomy of the family Parmeliaceae. Hale was one of the first liche ... transferred it to the genus '' Pseudoparmelia'' in 1974. It was later one o ...

Lourinhã
Lourinhã () is a municipality in the District of Lisbon, in the Oeste Subregion of Portugal. The population in 2011 was 25,735, in an area of 147.17 km². The seat of the municipality is the town of Lourinhã, with a population of 8,800 inhabitants. The present Mayor is João Duarte, elected by the Socialist Party. History The name Lourinhã possibly originated in the period of Roman domination, when a villa was located in the area. The origin of the medieval village is linked to ''Jordan'', a French knight who took part in the successful Siege of Lisbon in 1147. King Afonso Henriques granted Jordan the region of Lourinhã as fief and allowed him to grant a foral (letter of feudal rights) to its settlers in 1160. The name Lourinhã may be related to the origin of its feudal lord, since Jordan was from the Loire region in France. The rights of Lourinhã were confirmed by letters of King Sancho I in 1218 and again by Afonso III in 1258. The parish of Lourinhã became one ...

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 ...

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] |
Pseudoparmelia
''Pseudoparmelia'' is a genus of lichenized fungi in the family Parmeliaceae. The genus has a pantropical distribution, and contains 27 species. It was circumscribed by Bernt Arne Lynge in 1914, who distinguished the genus from ''Parmelia'' by the presence of pseudocyphellae on the underside of the lichen 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.

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] |
Mason Hale
Mason Ellsworth Hale, Jr. (September 23, 1929 – April 23, 1990) was one of the most prolific lichenologists of the 20th century. Many of his scholarly articles focused on the taxonomy of the family Parmeliaceae. Hale was one of the first lichen experts to incorporate secondary chemistry and technology such as computers and scanning electron microscopy into taxonomic work. Mason Hale published approximately two hundred articles and books on various aspects of lichen biology including taxonomy, anatomy, chemistry, and ecology. Hale also wrote several books aimed at education and increasing accessibility to lichens. Early life and education Mason Hale Jr. grew up on a farm outside of Winsted, Connecticut. He had an affinity towards biology from experiences from living on his family's farm. As an undergraduate, Hale wanted to be a linguist, but was not able to take specialized classes. Instead, he earned an undergraduate degree studying biology at Yale University, where he studied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavoparmelia Caperata
''Flavoparmelia caperata'', the common greenshield lichen, is a foliose lichen that grows on the bark of trees, and occasionally on rock. Identification ''Flavoparmelia caperata'' is a medium to large foliose lichen that has a very distinctive pale yellow green upper cortex when dry. The rounded lobes, measuring wide, usually have patches of granular soredia arising from pustules. The lobes of the thallus may be smooth, but quite often have a wrinkled appearance especially in older specimens. The lower surface is black except for a brown margin; rhizoids attached to the lower surface are black and unbranched. Similar species The very similar '' Flavoparmelia baltimorensis'' grows mainly on rock and has globose, pustular outgrowths (somewhat similar to isidia) on the upper surface of the lobes, but does not produce granular soredia Soredia are common reproductive structures of lichens. Lichens reproduce asexually by employing simple fragmentation and production of soredia and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punctelia Borreri
''Punctelia borreri'' is a species of foliose lichen in the family Parmeliaceae. It is a common and widely distributed species, occurring in tropical, subtropical, and temperate regions of Africa, Asia, Europe, North America, Oceania, and South America. The lichen typically grows on bark of deciduous trees, and less commonly on rock. Some European countries have reported increases in the geographic range or regional frequency of the lichen in recent decades, attributed alternatively to a reduction of atmospheric sulphur dioxide levels or an increase in temperatures resulting from climate change. The lichen is characterised by a greenish-grey to bluish-grey upper thallus surface, a black lower surface, pseudocyphellae on the surface of the thallus (tiny pores that facilitate gas exchange), and chemically, by the presence of gyrophoric acid in the medulla. There are several lookalike '' Punctelia'' species, including '' P. subrudecta'', '' P. perreticulata'', and '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
