Pelagophycidae is a subclass of heterokont algae.It is the sister group of the axodines.[2] Together, they form the class Dictyochophyceae.[1]

All known species are marine. They can be single-celled (coccoid or flagellate), palmelloid or filamentous. Some members (Pelagomonas) belong to picoplankton, and some other (Sarcinochrysis) are macroscopic attached organisms.[2]

The subclass contains 13 genera, 3 families and 2 orders (2017):[3][4]

It is expected that molecular studies will add more species to this list.[2]
