Coccomyxaceae

Coccomyxaceae is a family of algae, in the class Trebouxiophyceae.

[1] Members of the family Coccomyxaceae are microscopic algae found often in colonies surrounded by mucilage.

Cells multiply by simple vegetative division, sometimes by forming autospores, but not zoospores.

[2] The genus Paradoxia produces zoospores;[3] its placement in Coccomyxaceae is apparently due to a strain labeled as Paradoxia multiseta in the UTEX-Austin culture collection which was found to have a close phylogenetic relationship to Coccomyxa.

However, the morphology of the strain (having spherical cells) does not appear to match that of Paradoxia, making the identity suspect.
