Raphidomonadea is a class of Stramenopiles containing both photosynthetic and phagotrophic protists.

The phagotrophic groups are known as Raphopoda, and comprise actinophryid heliozoa and the marine genus Commation.

However, the phylogenetic analysis that accompanied the description placed it as the sister group of Haramonas, in the monotypic family Haramonadaceae.

The genus contains a single species, Chloromorum toxicum, which is a renaming of the taxon Chattonella cf.

Allegedly, Chloromorum composes a new algal class known as Chloromorophyceae, but due to not being validly published (i.e. nomen nudum), it is an illegal taxon.
