Richelia
Richelia is a genus of nitrogen-fixing, filamentous, heterocystous and cyanobacteria. They exist as both free-living organisms as well as symbionts within potentially up to 13 diatoms distributed throughout the global ocean. As a symbiont, Richelia can associate epiphytically and as endosymbionts within the periplasmic space between the cell membrane and cell wall of diatoms.
Richelia has been divided into several species on a genomic basis. Despite not being recognized by the LPSN, they remain useful in talking about the differences in genomic content and lifestyle of the groups they refer to.
