Taxonomic remark Originally described as fossil green alga (still listed in Codiaceae in AlgaeBase, 2021 version), but treated as calcified Cyanophyceae by more recent workers. From Liu et al., 2015: Cayeuxia resembles Hedstroemia in its distal expansion but differs in branching pattern. Dragastan (1985) considered Cayeuxia to be a junior synonym of Rivularia, but we retain the name Cayeuxia to distinguish these calcified skeletons from extant cyanobacteria whose diagnoses are based on details of soft organic tissues rather than on calcified parts.
