Pelagophyceae


Pelagophyceae is a class of heterokont algae. It is the sister group of the Dictyochophyceae.
All known species are marine. They can be single-celled, palmelloid or filamentous. Some members belong to picoplankton, and some other are macroscopic attached organisms.
The class contains 13 genera, three families and two orders :
  • 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.
