Hormotila Mucigena
''Hormotila'' is a genus of green algae in the family Chaetophoraceae. The genus was circumscribed by Antonino Borzì in 1883. The type species of ''Hormotila'', '' Hormotila mucigena'', as originally illustrated by Borzì, was a heterogenous assemblage of different algae. Some of his figures showed cells in laminated layers of mucilage, reminiscent of '' Gloeocystis'' or '' Urococcus''. In other figures, the cells were in branched, tubular layers of mucilage. Still other figures showed figures reminiscent of ''Oocystis'', ''Ankistrodesmus'' or ''Elakatothrix''. In 2016, Daniel E. Wujek and Michael J. Wynne redefined the genus by emending the description of the type species to only include the second sense, i.e. cells in branched tubes. Former family ''Hormotila'' was formerly the type genus of the family Hormotilaceae. , AlgaeBase AlgaeBase is a global species database of information on all groups of algae, both seaweed, marine and freshwater algae, freshwater, as well as ...

AlgaeBase
AlgaeBase is a global species database of information on all groups of algae, both seaweed, marine and freshwater algae, freshwater, as well as sea-grass. History AlgaeBase began in March 1996, founded by Michael D. Guiry, Michael Guiry. Text was copied from this source, which is available under aAttribution 4.0 International (CC BY 4.0)licence. (Sehere. By 2005, the database contained about 65,000 names. In 2013, AlgaeBase and the Flanders Marine Institute (VLIZ) signed an end-user license agreement regarding the intellectual property, Electronic Intellectual Property of AlgaeBase. This allows the World Register of Marine Species (WoRMS) to include taxonomic names of algae in WoRMS, thereby allowing WoRMS, as part of the Aphia database, to make its overview of all described marine species more complete. Synchronisation of the AlgaeBase data with Aphia and WoRMS was undertaken manually until March 2015, but this was very time-consuming, so an online application was developed ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Ankistrodesmus
''Ankistrodesmus'' is a genus of green algae in the family Selenastraceae. It is one of the most common types of phytoplankton in freshwater habitats around the world. The name ''Ankistrodesmus'' comes from the Greek roots ''ankistron'', meaning "cross", and ''desmos'', meaning "bond". Description ''Ankistrodesmus'' forms colonies of cells, usually found as loose bundles or tufts of cells. Sometimes the cells may twist around each other in the colony. Cells are many times longer than wide, and are variously needle-shaped, sickle-shaped, or sigmoid in outline. They contain a single chloroplast; the chloroplast usually contains a single pyrenoid, but may contain none or several pyrenoids. Life cycle Reproduction occurs asexually; sexual reproduction is unknown in ''Ankistrodesmus''. It exclusively forms autospores, and does not appear to have a flagellated stage in its life cycle. Some strains of ''Ankistrodesmus'' have been observed to undergo programmed cell death. The evolu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oocystis
''Oocystis'' is a planktonic genus of mostly freshwater green algae of the Family (biology), family Oocystaceae. It is the type genus of its family. ''Oocystis'' is mostly found in freshwater habitats and has a cosmopolitan distribution. A few species are found in terrestrial, such as wet rocks, or in marine waters. Description ''Oocystis'' is solitary or borne in colonies of two, four or eight surrounded in a thin mucilaginous envelope or mother cell wall. The colony is up to 77 μm in diameter and oval to ellipsoid. Individual cells may be fusiform, ellipsoidal, oval or nearly spherical, 7–46 μm long. The cell wall is smooth but may be thickened at the poles. Cells contain one to many parietal chloroplasts. Asexual reproduction occurs by the formation of two, four or eight autospores which are released by the rupture of the parental cell wall. Sexual reproduction and flagellated stages have not been observed in this genus. Taxonomy The taxonomy of ''Oocystis'' is difficult ...

Mucilage
Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage. It is a polar glycoprotein and an exopolysaccharide. Mucilage in plants plays a role in the storage of water and food, seed germination, and thickening membranes. Cacti (and other succulents) and flax seeds are especially rich sources of mucilage. Occurrence Exopolysaccharides are the most stabilising factor for microaggregates and are widely distributed in soils. Therefore, exopolysaccharide-producing "soil algae" play a vital role in the ecology of the world's soils. The substance covers the outside of, for example, unicellular or filamentous green algae and cyanobacteria. Amongst the green algae especially, the group Volvocales are known to produce exopolysaccharides at a certain point in their life cycle. It occu ...
