Graphium Samogiticum
''Graphium samogiticum'' is a little-known species of lichenicolous (lichen-eating) fungus in the family Microascaceae. It is found in Lithuania, where it parasitises two lichen species that inhabit abandoned gravel pits. Taxonomy The fungus was formally described as a new species in 2006 by Jurga Motiejūnaitė and Vagn Alstrup. The type specimen was collected in Žemaitija National Park (Plungė District); there, in an abandoned gravel pit in Žalnierkalnis, the fungus was found growing on the thallus of the crustose lichen '' Verrucaria bryoctona'', which itself was growing on gravelly soil. The species epithet refers to the type locality: ''samogiticum'' is formed from the Latin name for Žemaitija ('' Samogitia''). Description ''Graphium samogiticum'' is an anamorphic fungus, meaning that its sexual cycle has not been observed, or does not exist–only asexual and vegetative phases are known. The conidiophores made by the fungus are grouped together in black s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichenicolous Fungus
A lichenicolous fungus is a parasitic fungus that only lives on lichen as the host. A lichenicolous fungus is not the same as the fungus that is the component of the lichen, which is known as a lichenized fungus. They are most commonly specific to a given fungus as the host, but they also include a wide range of pathogens, saprotrophs, and commensals. It is estimated there are 3000 species of lichenicolous fungi. More than 1800 species are already described among the Ascomycota and Basidiomycota.Lichenicolous Fungi: Interactions, Evolution, and Biodiversity, Lawrey, James D.; Diederich, Paul.

Samogitia
Samogitia or Žemaitija ( Samogitian: ''Žemaitėjė''; see below for alternative and historical names) is one of the five cultural regions of Lithuania and formerly one of the two core administrative divisions of the Grand Duchy of Lithuania alongside Lithuania proper. Žemaitija is located in northwestern Lithuania. Its largest city is Šiauliai. Žemaitija has a long and distinct cultural history, reflected in the existence of the Samogitian language. Etymology and alternative names Ruthenian sources mentioned the region as жемотьская земля, ''Žemot'skaja zemlja''; this gave rise to its Polish form, , and probably to the Middle High German . In Latin texts, the name is usually written as etc. The area has long been known to its residents and to other Lithuanians exclusively as Žemaitija (the name Samogitia is no longer in use within Lithuania and has not been used for at least two centuries); Žemaitija means "lowlands" in Lithuanian. The region is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sarcosagium Campestre
''Sarcosagium'' is a genus of fungi in the family Thelocarpaceae Thelocarpaceae is the sole family of lichen-forming fungi in the order Thelocarpales. The family contains two genera, '' Sarcosagium'' and '' Thelocarpon''. The family was circumscribed by lichenologist Hugo Zukal in 1893, while the order was ....

Host (biology)
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasitic, a mutualistic, or a commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cells harbouring pathogenic (disease-causing) viruses, a bean plant hosting mutualistic (helpful) nitrogen-fixing bacteria. More specifically in botany, a host plant supplies food resources to micropredators, which have an evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an association is much larger than the other, it is generally known as the host. In parasitism, the parasite benefits ...

Peltigera
''Peltigera'' is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. Commonly known as the dog or pelt lichens, species of ''Peltigera'' are often terricolous (growing on soil), but can also occur on moss, trees, rocks, and many other substrates in many parts of the world. Most species of ''Peltigera'' have the cyanobacterium ''Nostoc'' as the dominant photobiont but some have the algae '' Coccomyxa.'' The presence of both a green alga and a cyanobacterium makes some tripartite; in this case they show cephalodium growths containing the third partner, ''Nostoc''. Because of their ability to fix nitrogen from the atmosphere, such lichens are influential in soil composition and generation. Description Species of ''Peltigera'' are foliose, with broad lobed thalli. Although the size of the thalli is variable and species-dependent, in some species the thalli can grow quite large, up to 30 cm in diameter.Vitikainen O. (1994). (1998). Taxonomic ...

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 Fr ...

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 coni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer ( American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix " micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length.
