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.[1]
Evolution
Synchromophyceae is a class within the Ochrophyta that contains a few genera of amoeboid organisms, such as the mixotrophic Synchromonas and the heterotrophic Chlamydomyxa and Leucomyxa.[3] It is phylogenetically close to the classes Chrysophyceae and Picophagea, within the SII clade.[4][2]

Taxonomy
The class Synchromophyceae was described in 2007 to include the genus Synchroma.[1] Since then, other closely-related organisms have been added. As of 2024, three orders are recognized, each containing one genus, and two additional incertae sedis genera.[2]
