Chrysochromulina inornamenta is a marine haptophyte microalga in the genus Chrysochromulina, class Prymnesiophyceae. The species epithet inornamenta — meaning unornamented — is particularly notable within a genus where most species are distinguished by elaborate scale ultrastructure. This name suggests that C. inornamenta either lacks the complex scale ornamentation typical of its congeners or possesses unusually simple scale morphology, making it an atypical member of the genus and potentially useful for understanding the evolution of scale complexity in haptophytes. C. inornamenta has been recorded from Norwegian and Swedish coastal marine waters, the primary region from which Chrysochromulina species diversity has been characterized through electron microscopy surveys. Norwegian and Swedish coastal environments include productive fjord systems and shelf waters supporting rich microplankton communities. Like other members of the genus, C. inornamenta is presumed to be a photoautotrophic or mixotrophic nanoplankton organism, capable of photosynthesis using chlorophylls a and c and associated carotenoid pigments. It possesses the characteristic haptophyte haptonema alongside two flagella. The haptonema coiling behavior distinguishes Chrysochromulina from the related genus Prymnesium. C. inornamenta has not been formally assessed under the IUCN Red List framework and carries a conservation status of Not Evaluated. Its existence highlights that even within a well-studied genus like Chrysochromulina, morphological diversity encompasses both highly ornamented and comparatively plain cellular phenotypes.
