Peyssonnelia Squamaria
''Peyssonnelia'' is a genus of thalloid red alga, named after naturalist Jean-André Peyssonnel (1694–1759) It includes the algae commonly known as rumoi-iwanokawa, mayoi-iwanokawa and akase-iwanokawa. Specimens can reach around 20 cm in size. ''Peyssonnelia'' produces tetraspores. Taxonomy and Nomenclature ''Peyssonnelia'' belongs to class Florideophyceae, of the order Peyssonneliales and Family Peyssonneliaceae. There are 89 currently recognized species as of 2021. Its lectotype is ''Peyssonnelia squamaria''. The genus is the largest in the Peyssonneliaceae. Segregate Genera The genera '' Cruoriella'' and '' Cruoriopsis'' are sometimes considered to be part of ''Peyssonnelia'', but a 2007 dissertation by Krayesky separates them. Morphology The genus is calcareous and is characterized by crustose, prostrate thalli attached to the substrate by uni- or multicellular rhizoids. Thalli may be partially or fully calcified, with calcium carbonate deposited as aragonit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Red Alga
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (Class (biology), class), and mostly consist of multicellular, ocean, marine algae, including many notable seaweed, seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-André Peyssonnel
Jean-André Peyssonnel (19 June 1694, Marseille – 24 December 1759, Saint-Bertrand, Guadeloupe) was a French physician and naturalist, known for his work in marine natural history. Content is translated from the existing French Wikipedia article; see its history for attribution. Biography Peyssonnel undertook his education at the Oration College in Marseille, where he was very attentive to the history of science, and after he obtained the degree of doctor of medicine in 1718 from the University of Aix-en-Provence. After beginning his career as a naturalist, his debut as a physician came also in 1720 during the Great Plague of Marseille, where his devotion to the sick earned him an annual royal stipend. The closeness of the sea and his scientific curiosity pushed him towards research into marine "productions" like coral, sponges, and algae. The count Luigi Ferdinand Marsigli (1658-1730), the founder of the Institute of Bologna, initiated him into the study of nat ...

Corallinaceae
The Corallinaceae are one of the two extant Coralline families of red algae; they are differentiated from the morphologically similar Sporolithaceae by their formation of grouped sporangial chambers, clustered into sori. The Corallinoideae is monophyletic; the other subfamilies form another monophyletic group. Genera The following genera are listed in the World Register of Marine Species: *Subfamily Amphiroideae **Genus '' Amphiroa'' J.V. Lamouroux, 1812 **Genus '' Lithothrix'' J.E. Gray, 1867 *Subfamily Corallinoideae **Genus '' Alatocladia'' (Yendo) Johansen, 1969 **Genus '' Arthrocardia'' Decaisne, 1842 **Genus ''Bossiella'' P.C.

Red Algae Genera
Red is the color at the long wavelength end of the visible spectrum of light, next to Orange (colour), orange and opposite Violet (color), violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged Scarlet (color), scarlet and Vermilion, vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy (color), burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayan civilization, Mayans colored their faces red in ceremonies; Roman Empire, Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brillian ...
