Description
Small sarcinoid packets of cells; cells spheroid to ellipt ical, united by thin gelatinous matrix ; distinct cell wall lacking; 2 parietal chloroplasts with stalked pyrenoid ; zoospores spheroid to elliptical with 2 flagella ; longer anteriorly directed flagellum with tripart ite tubular hairs (lacking lateral filaments) , shorter posteriorly directed flagellum without tripartite hairs ; eyespot absent; marine, coastal , in temperate waters , growing attached to substrates.
