Hydrurus is a genus of algae belonging to the family Hydruraceae. [1]
The genus has almost cosmopolitan distribution. [1]
Species: [1]
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.
Cystophora is a genus of brown algae found mostly in temperate waters around Australia. Most of the southern Australian species can be immediately recognised as belonging to this genus by their characteristic zigzag branching pattern. Identification of individual species is generally more difficult and relies on the size and shape of branches, particularly terminal branches, which are specialised reproductive structures known as receptacles. Due to their local diversity and dominance in southern Australia, they are regarded by some as 'the eucalypts of the underwater world'.
Giuseppe Antonio Risso, called Antoine Risso, was a Niçard and naturalist.
Oscillatoria is a genus of sugar making microscopic creatures.
Gracilaria is a genus of red algae (Rhodophyta) notable for its economic importance as an agarophyte, as well as its use as a food for humans and various species of shellfish. Various species in the genus are cultivated among Asia, South America, Africa and Oceania.
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.
Dictyotales is a large order in the brown algae containing the single family Dictyotaceae. Members of this order generally prefer warmer waters than other brown algae, and are prevalent in tropical and subtropical waters thanks to their many chemical defenses to ward off grazers. They display an isomorphic haplodiploid life cycle and are characterized by vegetative growth through a single apical cell. One genus in this order, Padina, is the only calcareous member of the brown algae.
Vaucheria is a genus of Xanthophyceae or yellow-green algae known as water felt. It is one of only two genera in the family Vaucheriaceae. The type species of the genus is Vaucheria disperma.
Nitella is a genus of charophyte green algae in the family Characeae.
Vidalia is a tropical red algae genus in the family Rhodomelaceae.
Chondria is a red alga genus in the family Rhodomelaceae.
Desmarestia is a genus of brown algae found worldwide. It is also called acid weed, acidweed, oseille de mer, sea sorrel, ウルシグサ, stacheltang, mermaid's hair, landlady's wig, or gruagach. However, 'sea sorrel' can also specifically refer to Desmarestia viridis. Members of this genus can be either annual or perennial. Annual members of this genus store sulfuric acid in intracellular vacuoles. When exposed to air they release the acid, thereby destroying themselves and nearby seaweeds in the process. They are found in shallow intertidal zones.
Hypnea is a genus of red algae, and a well known carrageenophyte.
Phyllophora is a genus of red algae in the family Phyllophoraceae.
Dictyota is a genus of brown seaweed in the family Dictyotaceae. Species are predominantly found in tropical and subtropical seas, and are known to contain numerous chemicals (diterpenes) which have potential medicinal value. As at the end of 2017, some 237 different diterpenes had been identified from across the genus.
Phyllariaceae is a family of brown algae in the order Tilopteridales.
Phyllospora is a genus of seaweeds in the family Seirococcaceae.
Gymnogongrus is a genus of red algae belonging to the family Phyllophoraceae.
Balliales is an order of red algae belonging to the class Florideophyceae. The order consists only one family, Balliaceae. with only one genus - BalliaHarvey.
Wrangelia is a genus of red algae in the family Wrangeliaceae.
