Flavopunctelia
''Flavopunctelia'' is a genus of foliose lichens in the family Parmeliaceae. The genus contains species that are widespread in temperate and tropical areas. The genus is characterised by broad, yellow-green lobes, point-like (''punctiform'') pseudocyphellae on the thallus surface, and bifusiform conidia (i.e., threadlike with a swelling at both ends). All species contain usnic acid as a major secondary chemical in the cortex. ''Flavopunctelia'' was originally conceived as a subgenus of ''Punctelia'' by Hildur Krog in 1982; Mason Hale promoted it to generic status in 1984.

Flavopunctelia Flaventior
''Flavopunctelia flaventior'' is a species of foliose lichen in the family Parmeliaceae. It was first formally described as a new species by James Stirton in 1877 as ''Parmelia flaventior''. In 1982, Hildur Krog transferred it to the subgenus ''Flavopunctelia'' of her newly circumscribed genus ''Punctelia'', created to contain '' Parmelia'' species with punctate (point-like) pseudocyphellae. Mason Hale raised this subgenus to generic status a couple of years later, setting ''Flavopunctelia flaventior'' as the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen ... of the new genus.

Flavopunctelia Praesignis
''Flavopunctelia praesignis'' is a species of foliose lichen in the family Parmeliaceae. It was first described as ''Parmelia praesignis'' by Finnish botanist William Nylander in 1872. In 1982, Hildur Krog transferred it to the subgenus ''Flavopunctelia'' of her newly circumscribed genus ''Punctelia'', created to contain '' Parmelia'' species with punctate (point-like) pseudocyphellae. Mason Hale raised this subgenus to generic status a couple of years later. The lichen is colloquially known as the fruiting speckled greenshield. It is found in the southern United States, in various states of Mexico, and in South America. It has also been reported from Kenya, but that may be due to misidentification.

Punctelia
''Punctelia'' is a genus of foliose lichens belonging to the large family Parmeliaceae. The genus, which contains about 50 species, was segregated from genus ''Parmelia'' in 1982. Characteristics that define ''Punctelia'' include the presence of hook-like to thread-like conidia (asexual spores), simple rhizines (root-like structures that attach the lichen thallus to its substrate), and point-like pseudocyphellae (tiny pores on the thallus surface that facilitate gas exchange). It is this last feature that is alluded to in the vernacular names speckled shield lichens or speckleback lichens. ''Punctelia'' lichens grow on bark, wood, and rocks. The genus is cosmopolitan, occurring on all continents but Antarctica. Species are found in temperate to subtropical locations. ''Punctelia'' has centres of distribution in the Neotropics and Africa; about half of the known species occur in South America. The photobiont partners of ''Punctelia'' are green algae in the genus ''Trebouxia''. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavopunctelia Darrowii
''Flavopunctelia darrowii'' is a species of foliose lichen in the family Parmeliaceae. It was first formally described as a new species by John Walter Thomson in 1950 as ''Parmelia darrowi''. It is named after American botanist Robert Arthur Darrow. In 1982, Hildur Krog transferred it to the subgenus ''Flavopunctelia'' of her newly circumscribed genus ''Punctelia'', created to contain '' Parmelia'' species with punctate (point-like) pseudocyphellae. Mason Hale raised this subgenus to generic status a couple of years later. The lichen is endemic to the American oak- pine forests of southern Arizona and higher elevations in Chihuahua and Sonora Sonora (), officially Estado Libre y Soberano de Sonora ( en, Free and Sovereign State of Sonora), is one of the 31 states which, along with Mexico City, comprise the Administrative divisions of Mexico, Federal Entities of Mexico.

Flavopunctelia Lobulata
''Flavopunctelia lobulata'' is a species of foliose lichen in the family Parmeliaceae. Found in Argentina, it was described as a new species in 1987 by lichenologists John Alan Elix and Mónica Adler. The type specimen was collected near Las Pailas (Salta Province), where it was found growing over mosses at an elevation of . It is similar in appearance to ''Flavopunctelia praesignis'', but differs from that species in being terricolous rather than corticolous, and by its smaller thalli, which measure in diameter. The specific epithet In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ... refers to its dense, somewhat erect lobulae (small lobes) in the centre of the thallus.

''Flavopunctelia borrerioides'' is a species of foliose lichen in the family Parmeliaceae. It was described as a new species by Japanese lichenologist Syo Kurokawa in 1999.

Parmeliaceae
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: '' Xanthoparmelia'' ( 822 species), ''Usnea'' (355 species), ''Parmotrema'' ( 255 species), and ''Hypotrachyna'' (262 species). Nearly all members of the family have a symbiotic association with a green alga (most often ''Trebouxia'' spp., but '' Asterochloris'' spp. are known to associate with some species).Miadlikowska, J.

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] |
Mycotaxon
''Mycotaxon'' is a peer-reviewed scientific journal that covers the nomenclature and taxonomy of fungi, including lichens. The journal was founded by Grégoire L. Hennebert and Richard P. Korf in 1974. They were frustrated that papers submitted to journals such as ''Mycologia'' took a year or longer from submission to publication. Korf and Hennebert introduced a number of innovations to make their journal more efficient and accessible than its contemporaries. ''Mycotaxon'' reduced the wait time between submission and publication by requiring authors to submit camera-ready copy. Linotype was the industry standard at the time; ''Mycotaxon'' used photo-offset lithography Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German a ... to expedite publication.

Hildur Krog
Hildur Krog (22 March 1922 – 25 August 2014) was a Norwegian botanist. She was born in Modum. She took the dr.philos. degree in 1968 with a thesis on Alaskan lichens, was hired as a curator at the Botanical Museum of Oslo in 1971 and served as professor at the University of Oslo from 1987 to 1992. For 15 year from 1969 she collaborated with the British amateur lichenologist Dougal Swinscow to study the macrolichen flora of East Africa. They undertook field collections as well as characterisation and revision of the limited existing lichen knowledge of the region, presented in 33 scientific publications and a book ''The Macrolichens of East Africa'', British Museum (Natural History) in 1988. In 1992 Hildur Krog was awarded the Acharius Medal by the International Association for Lichenology She was a fellow of the Norwegian Academy of Science and Letters. She died in 2014.
