Chroomonas baltica is a species of cryptophyte first described by J. Büttner in 1910, as Cyanomonas baltica.[1] It would be reclassified to its current genus by N. Carter in 1937.[2]
Büttner observed C. baltica off the coast of Strande in 1910, naming it Cyanomonas baltica, from the blue color of the chromatophore and the sea it was discovered.
