Raphidomonadea

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. The photosynthetic groups are known as the raphidophyte algae. Their relationship was elucidated through phylogenetic analyses.

Unplaced genera
The genus Psammamonas, described in 2013, is not placed in any family within the raphidomonads. However, the phylogenetic analysis that accompanied the description placed it as the sister group of Haramonas, in the monotypic family Haramonadaceae.

The genus Chloromorum is not a validly published name. Its first mention is from a 2008 journal article that states its author and publication as "Tomas et al., submitted for publication", but it was never published. The genus contains a single species, Chloromorum toxicum, which is a renaming of the taxon Chattonella cf. verruculosa. 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.
