Cecidochloris is a green algae genus in the family Chlorangiellaceae.

However, it has only been reported so far from Europe, with an additional species from India that is incompletely described.

Cells contain a single nucleus, one parietal chloroplast containing a single pyrenoid, a stigma, and two apical contractile vacuoles.

[1] Cecidochloris is morphologically similar to the genus Chlorophysema.

Cecidochloris is principally distinguished from the latter in that it lacks an organ, such as a stalk or basal pad, which is used to attach to the substrate.
