Filamentous brown alga distributed worldwide, notable as the first brown alga to have its full genome sequenced, published in 2010, establishing it as a key model organism.
Chaetomorpha linum is an unbranched filamentous green alga of sheltered lagoons and estuaries globally, often forming loose, unattached mats in nutrient-rich shallow waters.
Cladophora glomerata is a filamentous green alga notorious for forming dense nuisance blooms in eutrophic freshwater and brackish coastal ecosystems worldwide.
Cladophora rupestris is a dark green filamentous alga common on shaded rocky shores of the North Atlantic, persisting year-round in intertidal crevices and pools.
A delicate filamentous red alga of the northeastern Atlantic and Mediterranean, distinguished by whorled branchlets that produce a flower-like appearance when viewed under a microscope.
Chaetomorpha antennina is a stiff, unbranched filamentous green alga common on tropical and subtropical rocky intertidal shores, attaching to rock via a basal holdfast.
A delicate, filamentous red alga (Ceramiaceae) of the Mediterranean and Atlantic, named in honor of French phycologist Édouard Bornet (1828–1911), a pioneering authority on algal systematics.
A filamentous red alga of the North Atlantic and Mediterranean, recognized by its feathery, pinnately arranged opposite branchlets visible under microscopy in the family Antithamniaceae.
Nereia filiformis is a brown alga of the family Sargassaceae found in the Mediterranean Sea, distinguished by its thread-like, unbranched filaments on rocky substrata.
Rhodothamniella floridula is a small, turf-forming red alga of the family Nemaliaceae found on European Atlantic coasts, where it carpets intertidal rock surfaces.
Delicate filamentous red alga widespread in temperate and boreal seas, characterized by alternately branched filaments with distinctive banded corticated nodes visible along its length.
Rhizoclonium riparium is a filamentous green alga of brackish and saltmarsh habitats, forming entangled mats in upper intertidal zones on coasts worldwide.
Tilopteris mertensii is a filamentous brown alga that serves as the type species for the family Tilopteridaceae, classified by F.T. Kützing in 1849.
Common filamentous red alga forming dark wiry tufts on North Atlantic rocky shores and larger algae, with a characteristic polysiphonous axis comprising four pericentral cells.
Filamentous red alga of temperate North Atlantic shores, long-treated as a distinct species but now considered by many taxonomists to be synonymous with Ceramium virgatum Roth.
A minute, filamentous brown alga (Ectocarpaceae) occurring in temperate Atlantic and Mediterranean waters, typically growing epiphytically on the surfaces of larger seaweeds.
A tiny, club-shaped filamentous brown alga (Myriotrichiaceae) widespread in the North Atlantic, commonly colonizing the surfaces of other algae and seagrasses as an epiphyte.
Small filamentous brown alga widespread on temperate shores worldwide, notable for reproducing via distinctive forked or star-shaped vegetative propagules unique among algae.
Filamentous brown alga common on cold North Atlantic and North Pacific rocky shores, forming brown wiry tufts and a recognized persistent nuisance in seaweed aquaculture.
