Yoshimuria Galbina
''Yoshimuria'' is a genus of lichen-forming fungi in the family Teloschistaceae. It has four species of crustose lichens. Taxonomy The genus was circumscription (taxonomy), circumscribed in 2014 by a group of lichenologists, who assigned ''Yoshimuria spodoplaca'' as the type species. Three species were originally included in the genus. The genus name honours the Japanese lichenologist Isao Yoshimura, "for his many contributions to lichenology in Eastern Asia". ''Yoshimuria'' is in the subfamily Caloplacoideae of the family Teloschistaceae. Description ''Yoshimuria'' is characterised by a crust-like (crustose) thallus, which can vary greatly in thickness from very thin to thick and can be (i.e., divided by cracks into sections called ). The colour of the thallus ranges from whitish grey to dark grey or brownish grey. The apothecia of ''Yoshimuria'' (fruiting bodies) are either (with a ) or (without a thalline margin), and are typically (attached directly without a stalk). ...

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] |
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] |
Taxa Named By John Alan Elix
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 .

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 ( |
Teloschistales Genera
The Teloschistales are an order of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. According to one 2008 estimate, the order contains 5 families, 66 genera, and 1954 species. The predominant photobiont partners for the Teloschistales are green algae from the genera ''Trebouxia'' and '' Asterochloris''.

Index 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'' (''Speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyalolechia Stipitata
''Gyalolechia'' is a genus of lichen-forming fungi belonging to the family Teloschistaceae. It contains 18 species of crustose lichens. Taxonomy The genus was circumscribed by Abramo Bartolommeo Massalongo in 1852. He included two species: '' G. bracteata'' and '' G. aurea''. Although Massalongo did not designate a type species for the genus, Josef Poelt assigned ''G. aurea'' to that status in 1965. After Massalongo introduced the monotypic genus ''Fulgensia'' in 1853, ''Gyalolechia'' fell out of use. ''Gyalolechia'' was resurrected for use by Ulf Arup and colleagues in 2013, as part of a molecular phylogenetics-based restructuring of the Teloschistaceae. ''Gyalolechia'', which is sister to the genus ''Blastenia'', contains most of the species formerly assigned to the genus ''Fulgensia'', the species group centred around the taxon formerly known as ''Caloplaca flavorubescens'', and other species that contain fragilin as the dominant lichen product.

Parietin
Parietin is the predominant cortical pigment of lichens in the genus '' Caloplaca'', a secondary product of the lichen ''Xanthoria parietina'', and a pigment found in the roots of Curled Dock (''Rumex crispus''). It has an orangy-yellow color and absorbs blue light. It is also known as physcion. It has also been shown to protect lichens against UV-B light, at high altitudes in Alpine regions. The UV-B light stimulates production of parietin and the parietin protects the lichens from damage. Lichens in arctic regions such as Svarlbard retain this capability though they do not encounter damaging levels of UV-B, a capability that could help protect the lichens in case of Ozone layer thinning. It has also shown anti-fungal activity against barley powdery mildew and cucumber powdery mildew, more efficiently in the latter case than treatments with fenarimol and polyoxin B. It reacts with KOH to form a deep, reddish-magenta compound. Effect on human cancer cells Also found in rhu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
