Dibaeis Yurii
''Dibaeis yurii'' is a little-known species of terricolous (ground-dwelling) lichen in the family Icmadophilaceae. It is found in the Russian Far East and in South Korea. Taxonomy The lichen was formally described as new to science in 2014 by lichenologists Sergey Kondratyuk, Laszlo Lőkös, Soon-Ok Oh, and Jae-Seoun Hur. The type specimen was collected from the soil of a side road along the Razdolnoe-Khasan road (Khasansky District, Primorsky Krai). The species epithet ''yurii'' honours Yury Kondratyuk from Vladivostok, who helped the authors with lichen collections in Primorsky. The authors originally classified the species in genus ''Ochrolechia''. The next year they transferred it to ''Dibaeis'' after they sequenced some specimens and molecular phylogenetics analysis showed it to be a member of that genus. Description The dull greyish to brownish grey thallus of ''Dibaeis yurii'' reaches sizes of up to several centimetres across. Prominent on the thallus surface are the gr ...

Soredia
Soredia are common reproductive structures of lichens. Lichens reproduce asexually by employing simple fragmentation and production of soredia and isidia. Soredia are powdery propagules composed of fungal hyphae wrapped around cyanobacteria or green algae. These can be either scattered diffusely across the surface of the lichen's 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. Many of these organisms ..., or produced in localized structures called soralia. Fungal hyphae make up the basic body structure of lichen. The soredia are released through openings in the upper cortex of the lichen structure. After their release, the soredia disperse to establish the lichen in a new location.

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''.

Chuja Islands
The Chuja Islands () are a group of 42 islands in the Jeju Strait, about halfway between Jejudo and the southern coast of Jeollanamdo. Only four islands are inhabited: Sangchuja ("Upper Chuja"), which is connected by a bridge to Hachuja ("Lower Chuja"), the largest by area; Hoengang; and Chupo. The Chuja Islands are administered by Jeju City. As of December 31, 2019, the population is 1,733, based on the number of citizen registrations. History Chuja Islands are administered by Jeju City, but are geographically located adjacent to Wando-gun, Jeolla North Province, and the language and culture is similar to that of Jeolla North Province.

Detritus
In biology, detritus () is dead particulate organic material, as distinguished from dissolved organic material. Detritus typically includes the bodies or fragments of bodies of dead organisms, and fecal material. Detritus typically hosts communities of microorganisms that colonize and decompose (i.e. remineralize) it. In terrestrial ecosystems it is present as leaf litter and other organic matter that is intermixed with soil, which is denominated "soil organic matter". The detritus of aquatic ecosystems is organic material that is suspended in the water and accumulates in depositions on the floor of the body of water; when this floor is a seabed, such a deposition is denominated " marine snow". Theory The corpses of dead plants or animals, material derived from animal tissues (e.g. molted skin), and fecal matter gradually lose their form due to physical processes and the action of decomposers, including grazers, bacteria, and fungi. Decomposition, the process by whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladonia
''Cladonia'' is a genus of moss-like lichens in the family Cladoniaceae. They are the primary food source for reindeer/caribou. ''Cladonia'' species are of economic importance to reindeer-herders, such as the Sami in Scandinavia or the Nenets in Russia. Antibiotic compounds are extracted from some species to create antibiotic cream. The light green species '' Cladonia stellaris'' is used in flower decorations. Although the phylogeny of the genus ''Cladonia'' is still under investigation, two main morphological groups are commonly differentiated by taxonomists: the ''Cladonia'' morpho-type and the ''Cladina'' morpho-type. The ''Cladonia'' morpho-type has many more species, and is generally described as a group of squamulose (grow from squamules), cup-bearing lichens. The ''Cladina'' morpho-types are often referred to as forage lichens, mat-forming lichens, or reindeer lichens (due to their importance as caribou winter forage). '' Cladonia perforata'' ("perforate cladonia") is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spot Test (lichen)
A spot test in lichenology is a spot analysis used to help identify lichens. It is performed by placing a drop of a chemical on different parts of the lichen and noting the colour change (or lack thereof) associated with application of the chemical. The tests are routinely encountered in dichotomous keys for lichen species, and they take advantage of the wide array of lichen products produced by lichens and their uniqueness among taxa. As such, spot tests reveal the presence or absence of chemicals in various parts of a lichen. They were first proposed by the botanist William Nylander in 1866. Three common spot tests use either 10% aqueous KOH solution (K test), saturated aqueous solution of bleaching powder or calcium hypochlorite (C test), or 5% alcoholic ''p''-phenylenediamine solution (P test). The colour changes occur due to presence of particular secondary metabolites in the lichen. There are several other less frequently used spot tests of more limited use that are ...
