Endophyton is a genus of filamentous green algae comprising approximately 3 species. Branching is irregular. The medulla has a filamentous construction.
The species currently recognised are:E. laurenciae and E. atroviridis.
The Ulvophyceae or ulvophytes are a class of green algae, distinguished mainly on the basis of ultrastructural morphology, life cycle and molecular phylogenetic data. The sea lettuce, Ulva, belongs here. Other well-known members include Caulerpa, Codium, Acetabularia, Cladophora, Trentepohlia and Monostroma.

Ectocarpales is a very large order in the brown algae. The order includes families with pseudoparenchymatous (Splachnidiaceae) or true parenchymatous (Scytosiphonaceae) tissue. Pseudoparenchymatous refers to a filamentous alga with cells packed very close together to give an appearance of parenchymatous tissue, the latter being composed of cells which can truly divide in three dimensions, unusual among the algae. Filamentous algae are composed of cells that divide along a single plane, allowing only elongation to form filaments of one or more rows of cells. Algae that can divide in two planes can form sheet-like thalli or bodies. Cells that can divide in a third plane potentially allow for the organism to develop a more complex body plan, and diversification of body plans into an erect thallus of some sort and a holdfast for attaching the upright portion to the substrate.
Polysiphonia is a genus of filamentous red algae with about 19 species on the coasts of the British Isles and about 200 species worldwide, including Crete in Greece, Antarctica and Greenland. Its members are known by a number of common names. It is in the order Ceramiales and family Rhodomelaceae.
Bryopsidales is an order of green algae, in the class Ulvophyceae.
Chaetophoraceae is a family of green algae in the order Chaetophorales.
Trentepohlia is a genus of filamentous chlorophyte green algae in the family Trentepohliaceae, living free on terrestrial supports such as tree trunks and wet rocks or symbiotically in lichens. The filaments of Trentepohlia have a strong orange colour caused by the presence of large quantities of carotenoid pigments which mask the green of the chlorophyll.
Asparagopsis armata is a marine red algae species. It was first described in 1855 by Harvey, who found the algae on the Western Australian coast. Native to the Southern hemisphere, it has been introduced to the Northeastern Atlantic Ocean and the Mediterranean Sea.
Cylindrospermopsis is a planktonic genus of filamentous cyanobacteria known for its blooms in eutrophic waters. The type species is the tropical Cylindrospermopsis raciborskii (Woloszynska) Seenayya & Subbaraju. The cyanotoxin cylindrospermopsin was first identified from a species of this genus.
Zygnema is a genus of freshwater filamentous thalloid alga comprising about 100 species. A terrestrial species, Z. terrestre, is known from India. Zygnema grows as a free-floating mass of filaments, although young plants may be found anchored to streambeds with a holdfast. The filaments form a yellow-green to bright green colored tangled mat, and are composed of elongate barrel-shaped cells, each with two star-shaped (stellate) chloroplasts arrayed along the axis of the cell.
Raphidonema is a genus of filamentous green alga comprising five species. It is a member of the Trebouxiophyceae.
Klebsormidium is a genus of filamentous charophyte green algae comprising 20 species. The name was proposed in 1972 to resolve confusion in application and status of Hormidium. It occurs mostly in soil and on moist substrates, nevertheless, aquatic and one marine species are also known. Many Klebsormidium-species are able to synthesize substances for UV protection, the so-called mycosporine-like amino acids. The draft genome sequence of Klebsormidium flaccidum was published in 2014.
Trentepohlia aurea is a species of filamentous terrestrial green alga with a worldwide distribution. It grows on rocks, old walls and the trunks and branches of trees such as oaks and the Monterey cypress where the tree occurs in coastal central California. The orange coloration results from carotenoid pigments in the algal cells. It is probably the most widespread and abundant species of Trentepohlia in the Britain and Ireland.
Tribonema is a genus of filamentous, freshwater yellow-green algae. The holotype for the genus is the species Tribonema bombycina (C.Agardh) Derbès & Solier.
Anabaenopsis is a genus of filamentous, heterocystous cyanobacteria that reproduces by fragmentation and with akinetes. Anabaenopsis can produce microcystins, which are toxic to both humans and animals. The genus is primarily tropical and subtropical, with some species creating blooms in temperate regions during warmer seasons. Anabaenopsis contains bloom-formers among planktonic species.
Wollea is a genus of filamentous, heterocystous cyanobacteria that form macroscopic colonies in freshwater habitats. The genus produces akinetes and is known to reproduce with hormogonia.
Cyanonephron elegans is a freshwater species of cyanobacteria in the family Synechococcaceae. It is described in the Netherlands, Siberia, Russia and Queensland, Australia.
