Dolichospermum is a genus of cyanobacteria belonging to the family Nostocaceae.[1] 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.[2]
The genus has cosmopolitan distribution.[1]
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.[3]
