Pelagophyceae is a class of heterokont algae. It is the sister group of 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.[1]

The class contains 16 species in 13 genera and 2 orders (2017):[2]

  • order Pelagomonadales
    • family Pelagomonadaceae
      • genus Aureococcus
      • genus Chrysophaeum
      • genus Pelagococcus
      • genus Pelagomonas
  • order Sarcinochrysidales
    • family Sarcinochrysidaceae
      • genus Andersenia
      • genus Ankylochrysis
      • genus Aureoscheda
      • genus Aureoumbra
      • genus Chrysocystis
      • genus Chrysonephos
      • genus Chrysoreinhardia
      • genus Nematochrysopsis
      • genus Sarcinochrysis

It is expected that molecular studies will add more species to this list.[1]
