Stypopodium is a genus of thalloid brown alga in the family Dictyotaceae. Members of the genus are found in shallow tropical and subtropical seas around Africa, Pakistan, India, Japan, Indonesia, Australia, Micronesia, the Caribbean, Venezuela, and Brazil. [2]
The thalli are usually erect but sometimes prostrate, growing to a length of about 35 centimetres (14 in). They are attached to the substrate by a rhizoidal holdfast and often form bushy clumps. The blades are membranous and either wedge shaped or divided into linear segments. The sporangia are densely scattered over the surface of the blade or occur in irregularly-shaped sori, forming four spores. [2]
The World Register of Marine Species includes the following species in the genus: [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.
Porphyra is a coldwater seaweed that grows in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species, comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori and gim. There are considered to be 60 to 70 species of Porphyra worldwide and seven around Britain and Ireland where it has been traditionally used to produce edible sea vegetables on the Irish Sea coast. Porphyra is a chief source of plant-based vitamin B12.
Codium is a genus of seaweed in the Chlorophyta of the order Bryopsidales. There are about 50 species worldwide.
Cystoseira is a genus of brown algae in the order Fucales.
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.
Halymenia a genus of a macroscopic red algae that grows in oceans worldwide. It includes the following species:
Rhodomelaceae is estimated to be the largest red algae family, with about 125 genera and over 700 species.
Bangia is an extant genus of division Rhodophyta that grows in marine or freshwater habitats. Bangia has small thalli with rapid growth and high reproductive output, and exhibits behavior characteristic of r-selected species. The plants are attached by down-growing rhizoids, usually in dense purple-black to rust-colored clumps. The chloroplasts of Bangia, like others in the division Rhodophyta, contain chlorophyll a and sometimes chlorophyll d, as well as accessory pigments such as phycobilin pigments and xanthophylls. Depending on the relative proportions of these pigments and the light conditions, the overall color of the plant can range from green to red to purple to grey; however, the red pigment, phycoerythrin, is usually dominant.
Corallina is a genus of red seaweeds with hard, abrasive calcareous skeletons in the family Corallinaceae. They are stiff, branched plants with articulations.
Plocamium is a genus of red algae in the family Plocamiaceae. It contains around 40 species and has a cosmopolitan distribution in temperate seas. Plocamium has erect elliptical thalli that grow up to 50 cm (20 in) in length. They are bright red in color with strongly flattened delicately branching fronds that further divide into two to five smaller branchlets.
Stypopodium zonale is a species of thalloid brown alga in the family Dictyotaceae. It is found in shallow waters in the Caribbean Sea and in various other tropical and sub-tropical seas around the world.
Gigartinaceae is a red algae family in the order Gigartinales.
Phyllophora is a genus of red algae in the family Phyllophoraceae.
Mastocarpus papillatus, sometimes called Turkish washcloth, black tar spot, or grapestone is a species of red algae in the family Phyllophoraceae. It is sometimes confused with the distantly related Turkish towel which is of a similar texture but larger. The specific epithet papillatus is due to the nipple-like projections on the female gametophyte which can give the texture of a terrycloth washcloth found at a Turkish bath.
Dictyota is a genus of 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.
Padina boergesenii, commonly known as the leafy rolled-blade alga, is a species of small brown alga found in the tropical and subtropical western Atlantic Ocean, the Mediterranean Sea, and the Pacific Ocean. This seaweed was named in honour of the Danish botanist and phycologist Frederik Børgesen.
Cyclotella is a genus of diatoms often found in oligotrophic environments, both marine and fresh water. It is in the family Stephanodiscaceae and the order Thalassiosirales. The genus was first discovered in the mid 1800s and since then has become an umbrella genus for nearly 100 different species, the most well-studied and the best known being Cyclotella meneghiniana. Despite being among the most dominant genera in low-productivity environments, it is relatively understudied.
Spatoglossum is a marine brown algal genus in the family Dictyotaceae, with a worldwide distribution
