Belongs within: Rhodophyta.Contains: Nemaliophycidae, Corallinales, Ahnfeltiophycidae, Ceramiales, Gracilariales, Plocamiaceae, Halymeniales, Rhodymeniales, Nemastomatales, Gigartinales, Gelidiales. The Florideophycidae are a clade of multicellular red algae that ancestrally exhibit a triphasic life cycle. Cells are linked by pit connections with basal lineages often being distinguishable by the features of these connections (Adl et al. 2019). Little discs of… Continue reading Florideophycidae

Belongs within: Ceramiales.Contains: Polyzonieae, Chondria, Pterosiphonieae, Herposiphonieae, Bostrychieae, Laurencia, Lophothalieae, Amansieae, Polysiphonia. The Rhodomelaceae are a diverse family of red algae growing as uniaxial, polysiphonous thalli in which pericentral cells are cut off in alternate order. The thallus is parenchymatous in members of tribes Chondrieae and Laurencieae, whereas it is terete or compressed in other… Continue reading Rhodomelaceae

Belongs within: Delesseriaceae. Hypoglossum is a genus of erect red algae with flat thallus blades that are monostromatic except for the midribs (Womersley 2003). Put out your tongue Published 4 June 2026 Though they are the most diverse of the major groups of algae by a considerable margin, red algae tend not to draw the… Continue reading Hypoglossum

Belongs within: Nemaliophycidae. The Batrachospermales are a group of freshwater red algae characterised by uniaxial gametophytes, together with pit plugs with a domed outer cap layer but no cap membrane (Müller et al. 2002). Frog spawn multipliers Published 10 March 2025 When writing previously about red algae on this site, my subject has been of… Continue reading Batrachospermales

Belongs within: Florideophycidae.Contains: Hapalidiaceae, Corallinoideae, Lithophylloideae. The Corallinales, coralline algae, are a group of red algae characterised by a calcified thallus and the production of reproductive structures in conceptacles. Coral: it’s not just an animal thing Published 1 September 2008 Coral reefs form the world’s most renowned tropical marine habitat, and are some of the… Continue reading Corallinales

Belongs within: Corallinales. The Lithophylloideae are coralline red algae in which cells of adjacent vegetative filaments are joined by secondary pit connections (Bailey 1999). A coralline joint Published 21 March 2023 Classification of the coralline red algae has historically swirled around a central conflict. On a superficial level, the corallines can be readily divided between… Continue reading Lithophylloideae
