The family Chaetocerotaceae Ralfs in Pritchard 1861, is a diatom family (Bacillariophyceae). This family comprise the three genera Attheya T. West, Bacteriastrum Shadbolt and Chaetoceros Ehrenberg. Chaetoceros is arguably the largest and most species rich genus of marine planktonic diatoms. The taxonomic status within Chaetocerotaceae at present is somewhat unclear. [more]

Chorda is a genus of thalloid brown algae including two species. Its members are known by a number of common names. [more]

Chordariaceae

Chordariaceae is a family in the class Phaeophyceae (brown algae). Members of this family are may be filamentous, crustose with fused cells at the base or they may be terete and differentiated into a central medulla and an outer photosynthetic cortex. They have a sporphytic thallus usuallay aggregated to form a pseudo parenchyma. [more]

Cutleriaceae

Cutleriales is an order in the brown algae (class Phaeophyceae). It is composed of 2-6 genera, based upon various circumscriptions. The circumscription in the taxobox (right) is the list of genera from AlgaeBase, although only 3 of these genera are listed as containing species, 11 species in Cutleria, and one each in Microzonia, and Zanardinia. Lee circumscribes the order with only the two genera, Cutleria and Zanardinia. [more]

Diatomaceae

Diatoms are a major group of algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragillaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stellate colonies (e.g. Asterionella). Diatoms are producers within the food chain. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, but usually consist of two asymmetrical sides with a split between them, hence the group name. Fossil evidence suggests that they originated during, or before, the early Jurassic Period. Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water quality. [more]

Dictyotaceae is large family of brown algae (class Phaeophyceae). Members of this order generally prefer warmer waters than other brown algae. One genus in this order is calcareous, , the only calcareous member of this class. Lobophera variegata (= Pocockiella varieagata) often presents a beautiful blue iridescence due to microscopic bacteria which live on the surface of the leaves. [more]
