Blidingia marginata is a species of seaweed in the Kornmanniaceae family. [2]
The species is 2–5 centimetres (0.79–1.97 in) high, 100–200 μm (4–8×10−3 in) wide and 12–100 micrometres (0.00047–0.00394 in) thick. It has 15-20 cells, each of which is 10 micrometres (0.00039 in) long. [3]
It can be found in such African countries as Azores, South Africa, [2] Algeria, and Morocco. [1] It can be found in various gulfs, oceans and seas such as Gulf of Maine and Gulf of Mexico, in Atlantic Ocean and Mediterranean Sea. [2] It is also common on Bermuda, Cuba, and Tristan da Cunha. [1] The North American distribution is varied by state in the United States but can be found in Canada and Mexico as well. The states that carry the species are Georgia, North Carolina, Virginia, [3] Connecticut, Maine, Massachusetts and New Jersey. In Asia it is found only in Japan while in South America it is found in Argentina, Brazil and Uruguay. [1]
It is found in New Zealand and southern Australia where it is found in Recherche Archipelago, [4] Streaky Bay, Ardrossan and Port Adelaide. [5]
In Europe, it is found in Belgium, Ireland, France, Spain, Sweden, [2] and United Kingdom. [1] It is also common on the shores of Portugal and Norway. [3]
The species is commonly found with Juncus species.
Chlorophyta is a taxon of green algae informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it is a highly paraphyletic group of all the green algae within the green plants (Viridiplantae) and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic organisms. In newer classifications, it is the sister clade of the streptophytes/charophytes. The clade Streptophyta consists of the Charophyta in which the Embryophyta emerged. In this latter sense the Chlorophyta includes only about 4,300 species. About 90% of all known species live in freshwater. Like the land plants, green algae contain chlorophyll a and chlorophyll b and store food as starch in their plastids.
Phycology is the scientific study of algae. Also known as algology, phycology is a branch of life science.
The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca, lactuca being Latin for "lettuce". The genus also includes the species previously classified under the genus Enteromorpha, the former members of which are known under the common name green nori.
Halimeda is a genus of green macroalgae. The algal body (thallus) is composed of calcified green segments. Calcium carbonate is deposited in its tissues, making it inedible to most herbivores. However one species, Halimeda tuna, was described as pleasant to eat with oil, vinegar, and salt.
Porphyra is a genus of coldwater seaweeds that grow in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species, comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori and gim. There are considered to be 60–70 species of Porphyra worldwide and seven around Britain and Ireland, where it has been traditionally used to produce edible sea vegetables on the Irish Sea coast. The species Porphyra purpurea has one of the largest plastid genomes known, with 251 genes.
Codium is a genus of edible green macroalgae under the order Bryopsidales. The genus name is derived from a Greek word that pertains to the soft texture of its thallus. One of the foremost experts on Codium taxonomy was Paul Claude Silva at the University of California, Berkeley. P.C. Silva was able to describe 36 species for the genus and in honor of his work on Codium, the species C. silvae was named after the late professor.
The history of phycology is the history of the scientific study of algae. Human interest in plants as food goes back into the origins of the species, and knowledge of algae can be traced back more than two thousand years. However, only in the last three hundred years has that knowledge evolved into a rapidly developing science.
Hildenbrandia is a genus of thalloid red alga comprising about 26 species. The slow-growing, non-mineralized thalli take a crustose form. Hildenbrandia reproduces by means of conceptacles and produces tetraspores.
Hydroclathrus is a genus of perforate brown alga, of the phylum Ochrophyta and the class Phaeophyceae.
Pierre Jean-Louis Dangeard was a French botanist. He was the son of botanist and mycologist Pierre Augustin Dangeard and brother of geologist and oceanographer, Louis Dangeard.
Ulva linza is a green alga in the family Ulvaceae that can be found in British Isles.
Plocamium is a genus of red algae in the family Plocamiaceae. It contains around 40 species and has a cosmopolitan distribution in temperate seas, although it is most diverse in the southern hemisphere. It is widely distributed in tropical and also warm-temperate and cold-temperate seas, such as northern Europe, the northern Arabian Sea and western Australia. They are also found in the Antarctic regions of Admiralty Bay and Terra Nova Bay.
Ulva conglobata is a species of seaweed in the family Ulvaceae that can be found on Jeju Island of Korea, Qingdao province of China and Yokohama, Japan.
Ulva flexuosa now generally referred to as Enteromorpha flexuosa J. Agardh). is a species of seaweed in Ulvaceae family that can be found worldwide.
Ulva ohnoi is a species of light-green coloured seaweed in the family Ulvaceae that is endemic to Japan.
Blidingia dawsonii is a species of seaweed from a family of Ulvaceae that can be found in Canada, Mexico, and US states such as California and Washington. It was described by Hollenberg & I.A.Abbott in 1968. The species are disputed over genus, which some believe to be Percursaria.
Blidingia minima is a species of seaweed in the Kornmanniaceae family. It was described by Johann Kylin in 1947.
Hypnea is a genus of red algae, and a well known carrageenophyte.
Monostroma kuroshiense, a green alga in the division Chlorophyta, is a green seaweed endemic to Kuroshio Coast of Japan. This high-value seaweed is called Hitoegusa or Hirohano hitoegusa (ヒロハノヒトエグサ) in Japanese. Previously this algae was known in binomen Monostroma latissimum, but the latest scientific research based on multilocal phylogeny discovered that this is a new species. The algae is named after Kuroshio Current, naming is done by phycologist Felix Bast This algae is commercially cultivated in East Asia and South America for the edible product "hitoegusa-nori" or "hirohano-hitoegusa nori", popular sushi wraps. Monostroma oligosaccharides with degree of polymerization 6 prepared by agarase digestion from Monostroma nitidum polysaccharides have been shown to be an effective prophylactic agent during in vitro and in vivo tests against Japanese encephalitis viral infection. The sulfated oligosaccharides from Monostroma seem to be promising candidates for further development as antiviral agents. The genus Monostroma is the most widely cultivated genus among green seaweeds.
Wrangelia is a genus of red algae in the family Wrangeliaceae.
