The '''Palmophyllales''' are a deep-branching order of thalloid green alga, containing the single family '''Palmophyllaceae'''. They possibly form a sister group to the Chlorophyta. They survive today in deep waters, and can be found at 210 meters below the surface, where predation pressure is reduced.<ref>[https://phys.org/news/2010-11-deep-sea-algae-fossils.html Deep-sea algae may be 'living fossils' - Phys.org]</ref> The group contains the genera ''Palmophyllum'', ''Verdigellas'' and ''Palmoclathrus''.<ref name="Leliaert2011">{{Cite journal | last1 = Leliaert | first1 = F. | last2 = Verbruggen | first2 = H. | last3 = Zechman | first3 = F.
