Genera

Picozoa, Picobiliphyta, Picobiliphytes, or Biliphytes are protists of a phylum of marine unicellular heterotrophic eukaryotes with a size of less than about 3 micrometers. They were formerly treated as eukaryotic algae and the smallest member of photosynthetic picoplankton before it was discovered they do not perform photosynthesis.[2] The first species identified therein is Picomonas judraskeda.[1] They probably belong in the Archaeplastida as sister of the Rhodophyta.[3][4][5]

They were formerly placed within the cryptomonads-haptophytes assemblage.[6]
