''Dolichospermum'' is a genus of
cyanobacteria
Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteri ...
belonging to the family
Nostocaceae
The Nostocaceae are a family of cyanobacteria that forms filamentation, filament-shaped colony (biology), colonies enclosed in mucus or a gelatinous sheath. Some genera in this family are found primarily in fresh water (such as ''Nostoc''), whil ...

Anabaena
''Anabaena'' is a genus of filamentous cyanobacteria that exist as plankton. They are known for nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern. They are one of four genera of cyan ...
'' using molecular evidence. It is paraphyletic as the author intends: the genera ''
Aphanizomenon'' and ''
Cuspidothrix'', though cladistically included, have "distinct and unique" morphological features that set them apart.
The genus has
cosmopolitan distribution
In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and en ...
.
Many of the morphospecies in ''Anabaena'', ''Dolichospermum'', and ''Aphanizomenon'' (ADA clade) are not monophyletic. Work is underway to sequence more genomes from these genera to produce a species classification based on genetic branching.
