Fucophycidae

Fucophycidae is a subclass of Phaeophyceae (brown algae) which contains the most complex and evolved orders of Chromista algae. The members of this subclass have stalks with several morphological forms and distinct structures, characterized by an intercalary growth and a basic heteromorphic, sometimes secondarily iso- or sub-isomorphic life cycle.
