From Wikipedia, the free encyclopedia
Class of algae
Picophagea , also known as Synchromophyceae , is a class of
photosynthetic
stramenopiles .
[1]
[3]
[4] 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 .
[5] It is phylogenetically close to the classes
Chrysophyceae and
Eustigmatophyceae , within the SII clade.
[6]
Taxonomy
According to AlgaeBase, the class contains only two genera:
[7]
Class Picophagea Cavalier-Smith 2006 emend. 2017 [=Synchromophyceae S.Horn & C.Wilhelm 2007 ]
However, the latest revision recognizes an additional four genera:
Chrysopodocystis ,
Guanochroma ,
Leukarachnion and
Picophagus .
