Mallomonas is a genus of many from the phylum Ochrophyta, which describes organisms as having heterokont flagella in some part of their life history. At first, the family Mallomonadaceae was placed under class Chrysophyceae. However, after finding key biochemical and ultrastructural differences, the family was then placed under the class Synurophyceae. In a broader context, both Chrysophyceae and Synurophyceae are referred to as “chrysophytes”, meaning “golden algae”, because of their close similarities. Despite being quite similar, there are various, noticeable differences.
