Taxonomic status: currently recognized as a distinct genus.
Description: Cells in short or long filaments. Cells small, elongate, barrel-shaped with shallow median constriction (isthmus), one species with ring of spine-tipped protuberances on each semicell and narrower isthmus. Cell in apical view biradiate, omniradiate or, rarely, triradiate. Cell wall with transverse rows of desmid-type pores and logitudinally plicate near cell ends. Chloroplast one per semicell, stellate in end view, with central pyrenoid. Nucleus in isthmus between chloroplasts. Asexual reproduction by transverse cell division. Forming replicate cell wall during new semicell morphogenesis. Secondary wall layers of daughter semicells produced on each side of primary wall, including folded section around projecting primary wall cylinder. Morphogenesis completed by expansion of new semicells, tearing apart primary wall cylinder and unfolding plicate secondary wall cylinder. Daughter cells remain attached by central section of primary wall. On mature cell wall, position of secondary wall fold marked by shallow groove. Sexual reproduction by conjugation. Usually one conjugating filament breaks apart. Gametangia pair at right angles, the semicell walls split apart at the isthmus and gametes fuze between gametangia. Mature zygospores spherical to ellipsoid with smooth or mamillate walls. Bambusina among filamentous algae in acidic, oligotrophic, aquatic habitats mixed with other filamentous algae. B. borreri cosmopolitan, other species more rarely collected in Europe, Asia, Africa, Indonesia and North and South America.
Numbers of names and species: There are 19 species (and infraspecific) names in the database at present, of which 4 have been flagged as currently accepted taxonomically.
Names: ('C' indicates a name that is currently accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
