Cyanidiales
Cyanidiophyceae is a class of unicellular red algae within subdivision Cyanidiophytina, and contain a single plastid, one to three mitochondria, a nucleus, a vacuole and floridean starch. Most are extremophiles inhabiting acid hot springs. The main photosynthetic pigment is C-phycocyanin. Reproduction is asexual by binary fission or formation of endospore An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota. The name "endospore" is suggestive of a spore or seed-like form (''endo'' means 'within'), but it is not a true spore (i.e., no ...s.

Galdieria Partita
''Galdieria partita'' is a species of extremophilic red algae that lives in acidic hot springs. It is the only unicellular species of red algae known to reproduce sexually. It was discovered in 1894 by Josephine Elizabeth Tilden from Yellowstone National Park in the western United States. Originally described as a specides of green algae, ''Chroococcus varium'', its scientific name and taxonomic position were revised several times. In 1959, Mary Belle Allen produced the pure culture which has been distributed as the "Allen strain". History Josephine Elizabeth Tilden, the first woman teacher at the University of Minnesota, investigated algae of the Yellowstone National Park in Wyoming in 1894. Among her collection was a species which she identified as a green alga. In 1898, she named it ''Protococcus botryoides'' f. ''caldarium.'' Austrian biologists Lothar Geitler and Franz Ruttner revised the identification as a blue-green algae with a name ''Cyanidium caldarium'' in 1936. A ...

Galdieria Sulphuraria
''Galdieria sulphuraria'' is an extremophilic unicellular species of red algae. It is the type species of the genus '' Galdieria''. It is known for its broad metabolic capacities, including photosynthesis and heterotrophic growth on over 50 different extracellular carbon sources. The members of the class Cyanidiophyceae are among the most acidophilic known photosynthetic organisms, and the growth conditions of ''G. sulphuraria'' – pH between 0 and 4, and temperatures up to 56 °C – are among the most extreme known for eukaryotes. Analysis of its genome suggests that its thermoacidophilic adaptations derive from horizontal gene transfer from archaea and bacteria, another rarity among eukaryotes. History and taxonomy Published descriptions of thermoacidophilic unicellular algae date to the mid-19th century. The earliest description of an organism corresponding to the modern ''G. sulphuraria'' was published in 1899 by an Italian scientist, A. Galdieri, who gave it the na ...

Red Algae
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), and mostly consist of multicellular, marine algae, including many notable 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 centrioles, chloroplasts that l ...

Red Algae Families
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 625–740 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 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 broug ...
