Picophagea, also known as Synchromophyceae, is a class of photosynthetic stramenopiles. The chloroplast of the Synchromophyceae are surrounded by two membranes and arranged in a way where they share the outer pair of membranes. The entire chloroplast complex is surrounded by an additional two outer membranes.
Evolution.
Synchromophyceae or Picophagea is a clade within the Ochrophyta that contains a few genera of amoeboid organisms such as the mixotrophic "Synchromonas" and the heterotrophic "Chlamydomyxa", "Leukarachnion" and "Picophagus". It is phylogenetically close to the classes Chrysophyceae and Eustigmatophyceae, within the SII clade.
Taxonomy.
According to AlgaeBase, the class contains only two genera:
However, the latest revision recognizes an additional four genera: "Chrysopodocystis", "Guanochroma", "Leukarachnion" and "Picophagus".
