Fasciculochloris is a genus of green algae in the family Chlorococcaceae.

[1] Young vegetative cells begin oblong and oval shaped, but eventually become rounded and spherical after aging.

Cell division has a chance of resulting in production of zoospores.

If the cell is vegetative, division may result in the formation of packets, most likely four, but can get up to thirty-two cells in two/three planes.
