Description: Homocytous filaments, forming light to dark black, prostrate, sometimes fascicular thallus, on submerged and/or exposed marine littoral substrata, epilithic on limestone or epipelic on sand and silt forming mats within mangroves. Trichomes uniseriate, cylindrical, and 16) in younger trichomes, while less constricted or not in older, facultative attenuation with bent ends, sheaths absent; highly motile and oscillate by bending and rotating counterclockwise at ends. Cells discoid, shorter than wide, apical cell rounded, blunt and narrowed, with occasional yellow calyptra. Cell content red, rust, light to dark green, purple, grey, yellow, gold, brown, facultative granulated crosswalls. All cells capable of division. Reproduction by fragmentation, necridia, and hormogonia.

Origin of description: this description is from the original publication; it may have been modified slightly. The most recent alteration to this page was made on 2023-03-03 by M.D. Guiry.

Gender: This genus name is currently treated as neuter.

Most recent taxonomic treatment adopted: Strunecký, O., Ivanova, A.P. & Mares, J. (2022 '2023'). An updated classification of cyanobacterial orders and families based on phylogenomic and polyphasic analysis (Review). Journal of Phycology 59(1): 12-51.

Comments: Pigmentation shifts throughout development. Plastic morphology throughout trichome development and among strains observed. Constriction between even groups of cells gives the appearance of barrels.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
