Dolichospermum is a genus of cyanobacteria belonging to the family Nostocaceae. It was created by splitting from Anabaena 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.
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.
