Peyssonnelia Capensis
''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 aragonite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Decaisne
Joseph Decaisne (7 March 1807 – 8 January 1882) was a French botanist and agronomist. He became an ''aide-naturaliste'' to Adrien-Henri de Jussieu (1797–1853), who served as the chair of rural botany. It was during this time that he began to study plants brought back by various travelers like those of Victor Jacquemont (1801–1832) from Asia. Decaisne used applied research, most notably on the agronomy of the madder, the yam and the ramie. He was also interested in algae. Biography Although born in Brussels, Belgium, he exercised his activity exclusively in Paris. He entered in 1824 as a gardener at the ''Muséum national d'histoire naturelle'' (French museum of natural history) and became, in 1832, head of the ''carré des semis'' section. He also worked at the '' Jardin des Plantes'' and collaborated with Asa Gray. In 1847 he chaired Statistical Agriculture department in the College de France. In 1850, Decaisne followed Charles-François Brisseau de Mirbel (1776–185 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Alga
Red algae, or Rhodophyta (, ; ), make up one of the oldest groups of eukaryotic algae. The Rhodophyta comprises one of the largest Phylum, phyla of algae, containing over 7,000 recognized species within over 900 Genus, genera amidst ongoing taxonomic revisions. The majority of species (6,793) are Florideophyceae, and mostly consist of multicellular, ocean, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, no terrestrial species exist, 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. Red algae form a distinct group characterized by eukaryotic cells without flagella and centrioles, chloroplasts without external endoplasmic reticulum or unstack ...

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 natural ...

Cruoriopsis
''Cruoriopsis'' is a genus of non-corraline red algae. It has sometimes been considered a synonym of ''Cruoriella'' Crouan & Crouan or part of the larger genus '' Peyssonnelia''. Taxonomy The taxonomy of ''Cruoriopsis'' and some other genera now in the family Peyssonneliales, including ''Cruoriella'' and '' Cruoria'', have been the subject of much discussion over decades. ''Cruoriopsis'' first became synonymous with ''Cruoriella,'' which in turn became synonymous with '' Peyssonnelia''. Despite the fact that ''Cruoriopsis'' is an unnaccepted name taxonomically, four species remain within ''Cruoriopsis incertae sedis or is a term used for a taxonomy (biology), taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty ...'': ''C. danica, C. ensisae, C. hauckii,'' and ''C. reinboldii.''

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.

Red Algae Genera
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–750 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 and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; 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 brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought ...

Peyssonneliales
Peyssonneliales is a monotypic order of red algae belonging to the class Florideophyceae and the subclass Rhodymeniophycidae. It contains only 1 known family, Peyssonneliaceae . The type species is '' Peyssonnelia'' History Genera ''Peyssonnelia'' and ''Sonderopelta'' were originally in order Gigartinales but comparative morphology and rbcL and nuclear LSU rRNA sequence data showed that they were separate and therefore order ''Peyssonneliales'' was established in 2009 to hold them both. ''Incendia'' was initially resolved as a monophyletic clade with full support for rbcL. Then using robust rbcL phylogeny, order Peyssonneliales was lso resolved as monophyletic with well-supported main lineages. Description Delineation of the various genera in the Peyssonneliaceae had mostly been based on vegetative characteristics. Peyssonneliales order algae are red, crustose, prostrate, and usually epilithic (growing on the surfaces of rocks). The crusts may be non-calcified throughout, ...
