Subclass of algae

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

Quick Facts Scientific classification, Orders ...

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]

  • Order Pelagomonadales Andersen & Saunders 1993
    • Family Pelagomonadaceae Andersen & Saunders 1993
      • genus Ankylochrysis Billard 1995
      • genus Aureococcus Hargraves & Sieburth 1988
      • genus Chrysophaeum Lewis & Bryan 1941 non Taylor 1951
      • genus Pelagococcus Norris 1977
      • genus Pelagomonas Andersen & Saunders 1993
  • Order Sarcinochrysidales Gayral & Billard 1977
    • Family Chrysocystaceae Melkonian, Yoon & Andersen 2018
      • genus Chrysocystis Lobban, Honda & Chihara 1995
      • genus Chrysoreinhardia Billard 2000
      • genus Sungminbooa Yoon & Andersen 2018
    • Family Sarcinochrysidaceae Gayral & Billard 1977
      • genus Andersenia Wetherbee & Waller 2015
      • genus Arachnochrysis Andersen & Han 2018
      • genus Aureoscheda Wynne & Andersen 2014
      • genus Aureoumbra Stockwell et al. 1997
      • genus Chrysonephos Taylor 1952
      • genus Nematochrysopsis Billard 2000
      • genus Pelagospilus Andersen & Graf 2018
      • genus Sarcinochrysis Geitler 1930
      • genus Sargassococcus Andersen & Han 2018

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