Lepidocollema Wainioi
''Lepidocollema wainioi'' is a species of lichen in the family Pannariaceae. It is known from southeast Asia. Taxonomy This lichen was originally formally described by Finnish lichenologist Edvard August Wainio as ''Pannaria sorediata'', based on material collected from the Philippines. However, Wainio was unaware that this name had already been used for another taxon by Charles Knight in 1882, and so the name ''Pannaria sorediata'' was an illegitimate homonym, and therefore, not validly published. Austrian botanist Alexander Zahlbruckner, in his 1925 work ''Catalogus Lichenum Universalis'', renamed the lichen in honour of Wainio, and it then became known as ''Pannaria wainioi'' . Per Magnus Jørgensen transferred the species to the genus ''Parmeliella'' in 2003. In 2014, the family Pannariaceae was revised with the aid of modern molecular phylogenetics, and ''Parmeliella wainioi'' was one of 23 tropical species transferred into the formerly monotypic genus ''Lepidocoll ...

Lepidocollema
''Lepidocollema'' is a genus of lichens in the family Pannariaceae. It was circumscribed in 1890 to contain a single Brazilian species that has not been collected since. In 2016, the entire family was revised and updated, resulting in the expansion of ''Lepidocollema'' to 24 tropical species. Taxonomay ''Lepidocollema'' was originally circumscribed in 1890 by Finnish lichenologist Edvard August Vainio with only the type species, '' L. carassense''. This lichen is a gelatinous ''Parmeliella''-like species that has a photobiont from the genus ''Nostoc''. It has only been collected once from Brazil. The family Pannariaceae was revised in 2014 with the help of molecular phylogenetics. As a result, the genus was accepted and 23 tropical species were transferred into it, mostly from the genus ''Parmeliella''. Phylogenetically, ''Lepidocollema'' is sister to '' Physma''. Description ''Lepidocollema'' is characterised by the formation of large, flat rosettes on a thick layer of rh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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''. Current names in ''Index Fungorum'' (''Specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MycoBank
MycoBank is an online database, documenting new mycological names and combinations, eventually combined with descriptions and illustrations. It is run by the Westerdijk Fungal Biodiversity Institute in Utrecht. Each novelty, after being screened by nomenclatural experts and found in accordance with the ICN ( International Code of Nomenclature for algae, fungi, and plants), is allocated a unique MycoBank number before the new name has been validly published. This number then can be cited by the naming author in the publication where the new name is being introduced. Only then, this unique number becomes public in the database. By doing so, this system can help solve the problem of knowing which names have been validly published and in which year. MycoBank is linked to other important mycological databases such as ''Index Fungorum'', Life Science Identifiers, Global Biodiversity Information Facility (GBIF) and other databases.

Sonneratia
''Sonneratia'' is a genus of plants in the family Lythraceae. Formerly the Sonneratia were placed in a family called Sonneratiaceae which included both the ''Sonneratia'' and the ''Duabanga'', but these two are now placed in their own monotypic subfamilies of the family ''Lythraceae''. The genus was also named ''Blatti'' by James Edward Smith, but ''Sonneratia'' had botanical nomenclature priority. ''Sonneratia'' species are mangrove trees. The germination is viviparous. Species The genus ''Sonneratia'' has the following species: *'' Sonneratia alba'' Sm. *'' Sonneratia apetala'' Banks *''Sonneratia caseolaris'' (L.) Engl. *'' Sonneratia griffithii'' Kurz *'' Sonneratia × gulngai'' N.C.Duke *'' Sonneratia × hainanensis'' W.C.Ko, E.Y.Chen & W.Y.Chen *'' Sonneratia lanceolata'' Blume *'' Sonneratia ovata'' Backer *'' Sonneratia × urama'' N.C.Duke See also *Mangroves References *Graham, S.

Avicennia
''Avicennia'' is a genus of flowering plants currently placed in the bear's breeches family, Acanthaceae. It contains mangrove trees, which occur in the intertidal zones of estuarine areas and are characterized by its "pencil roots", which are aerial roots. They are also commonly known as ''api api'', which in the Malay language means "fires", a reference to the fact that fireflies often congregate on these trees. Species of ''Avicennia'' occur worldwide south of the Tropic of Cancer. The taxonomic placement of ''Avicennia'' is contentious. In some classifications, it has been placed in the family Verbenaceae, but more recently has been placed by some botanists in the monogeneric family Avicenniaceae. Recent phylogenetic studies have suggested that ''Avicennia'' is derived from within Acanthaceae, and the genus is included in that family in the Angiosperm Phylogeny Group system. Designation of species is made difficult by the great variations in form of ''Avicennia marina''. B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ko Kut District
Ko Kut ( th, เกาะกูด, ) is a district (''amphoe'') of Trat province, eastern Thailand, consisting of a group of islands. With a population of 2,894 in 2011, it is the district with the smallest population of all Thailand. History Originally the area of the district was part of the sub-district (''tambon'') Ko Chang, Laem Ngop district. In 1952 the sub-district Ko Mak was established to cover the whole island, at that time subdivided into four villages ('' mubans''). In 1980 three villages of Ko Mak were split off to create sub-district Ko Kut. On 1 April 1990 the government upgraded ''tambon'' Ko Kut together with ''tambon'' Ko Mak to a minor district (''king amphoe''). The Thai government on 15 May 2007 upgraded all 81 minor districts to full districts. With publication in the ''Royal Gazette'' on 24 August the upgrade became official. As local government entities, the two tambon administrative organizations (TAO) were created in 2003 and 2004 respectively. The T ...

Rhizine
In lichens, rhizines are multicellular root-like structures, arising mostly from the lower surface. A lichen with rhizines is termed rhizinate, while a lichen lacking rhizines is termed erhizinate. Rhizines serve only to anchor the lichen to their substrate; they do not absorb nutrients as do plant roots. Characteristics of the rhizines are used to identify lichens, for example: whether they are dense or sparse, whether they are uniformly distributed or clumped in specific areas, and whether they are straight or branched. Only foliose lichens may possess rhizines, not crustose or fruticose lichens, which lack a lower cortex. Rhizohyphae are a type of attachment structure on some lichens. Rhizohyphae are more slender than rhizines and are one cell thick in diameter. Rhizohyphae often occur as a felt-like hyphal mass. See also *Rhizoid Rhizoids are protuberances that extend from the lower epidermal cells of bryophytes and algae. They are similar in structure and function to the ro ...

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 wer ..., 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.

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 were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
