Pelagophyceae
Pelagophyceae is a class of heterokont algae. It is the sister group of 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, 3 families and 2 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.
