Franwilsia
''Franwilsia'' is a genus of lichen-forming fungi in the family Teloschistaceae. It has three species. Taxonomy The genus was circumscribed in 2014 by lichenologists Sergey Kondratyuk, Ingvar Kärnefelt, John Alan Elix, Arne Thell, and Jae-Seoun Hur. It contains species formerly included in the ''Caloplaca bastowii''-group; the type species is ''Franwilsia bastowii''. The genus is in the subfamily Caloplacoideae in the Teloschistaceae. It forms a clade along with genus '' Eilifdahlia''. The genus name honours the reverend Francis Robert Muter Wilson, an early Australian lichenologist. Description ''Franwilsia'' is characterized by a thallus that can either be continuous or (broken into discrete areas). The cortical layer of the thallus is described as palisade , meaning it consists of tightly packed cells arranged in a palisade-like formation. The colour of the thallus ranges from whitish to grey or dark grey. The apothecia, or fruiting bodies, of ''Franwilsia'' are either ...

Franwilsia Bastowii
''Franwilsia bastowii'' is a species of ramicolous (twig-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk and Ingvar Kärnefelt. It was transferred to the genus ''Franwilsia'' in 2014. The species epithet ''bastowii'' honours the Scottish naturalist Richard Austin Bastow, who collected the type specimen in Mornington ( Gippsland plain) in 1901. The lichen is known to occur in Western Australia, 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 ..., and Victoria, where it grows on the twigs of various shrubs and trees.

Francis Robert Muter Wilson
Francis Robert Muter Wilson (1832–1903), Presbyterian minister at Kew, Melbourne, was arguably Australia's first lichenologist. He came to Australia in 1862 to minister at Kew, but developed an interest in the natural world. He discovered many Australian and Pacific Island species of lichens. His collecting trips took him to Lorne, Lakes Entrance, Ferntree Gully, Brisbane, Sydney and Suva, Fiji. Between 1897 and 1900 he wrote at least 20 articles on lichens, publishing many new species. After his death his collections were purchased by the National Herbarium of New South Wales and the National Herbarium of Victoria. However the latter set was sent to the Italian botanist Giacomo Albo to be studied, and was lost in transit, never to be recovered.

Teloschistaceae
The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family, estimated to contain over 1800 species, was extensively revised in 2013, including the creation or resurrection of 31 genera. It contains three subfamilies: Xanthorioideae, Caloplacoideae, and Teloschistoideae. A fourth subfamily, Brownlielloideae, proposed in 2015, has been shown to be part of the Teloschistoideae. Genera This is a list of the genera contained within the Teloschistaceae, based on a 2020 review and summary of ascomycete classification. Following the genus name is the taxonomic authority, year of publication, and the number of species: *'' Amundsenia'' – 2 spp. *'' Andina'' - 1 sp. *'' Apatoplaca'' – 1 sp. *'' Aridoplaca'' - 1 sp. *'' Athallia'' – 17 spp. *'' Austroplaca'' – 10 spp. *'' Blastenia'' – 11 spp. *'' Brownliella'' – 4 spp. *'' Bryoplaca'' – 3 spp. *'' Calogaya'' – 19 spp. *'' Calop ...

Ingvar Kärnefelt
Jan Eric Ingvar Kärnefelt (born 1944) is a Swedish lichenologist. Early life and education Kärnefelt was born in Gothenburg, Sweden in 1944. His initial goal in his higher-level studies at University of Cologne in 1966–1967 was to become a dentist. He changed courses in 1968, turning instead to biology at the University of Gothenburg in 1968. Gunnar Degelius, his first teacher during undergraduate studies in botany in 1968, inspired him and others. After Degelius' retirement in 1969, Ingvar continued his studies at Lund University, where Hans Runemark held a position in systematic botany. In 1971 he met Ove Almborn, who became his supervisor. In 1979, he defended his thesis titled "The brown fruticose species of ''Cetraria''". The thesis was later awarded a prize for the best doctoral dissertation in botany at Lund University during a 5-year period by the Royal Physiographic Society in Lund. Career Kärnefelt became associate professor at the Department of Systematic Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depside
A depside is a type of polyphenolic compound composed of two or more monocyclic aromatic units linked by an ester bond. Depsides are most often found in lichens, but have also been isolated from higher plants, including species of the Ericaceae, Lamiaceae, Papaveraceae and Myrtaceae. Certain depsides have antibiotic, anti- HIV, antioxidant, and anti-proliferative activity ''in vitro''. As inhibitors of prostaglandin synthesis and leukotriene B4 biosynthesis, some depsides have ''in vitro'' anti-inflammatory activity. A depsidase is a type of enzyme that cuts depside bonds. One such enzyme is tannase. Examples Gyrophoric acid, found in the lichen '' Cryptothecia rubrocincta'', is a depside. Merochlorophaeic acid, isolated from lichens of the genus '' Cladonia'', is an inhibitor of prostaglandin synthesis. Some depsides are described as anti-HIV.

Conidia
A conidium ( ; ), sometimes termed an asexual chlamydospore or chlamydoconidium (), is an asexual, non-motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' ''Metarhizium'') species. The terms microconidia and macroconidia are sometimes used. Conidiogenesis There are two main types of conidium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
