Description:
Microscopic and macroscopic organisms composed of branched filaments that may form pseudoparenchymatous masses, often growing on or in other organisms, more rarely free-living. Cells uninucleate, containing a single parietal chloroplast with one or more pyrenoids. Colourless hairlike projections (setae) are present or absent; when produced, they are nonseptate and anucleate. Asexual reproduction by biflagellate, triflagellate or quadriflagellate zoospores. Sexual reproduction anisogamous, rarely isogamous; gametes biflagellate. Sporangia and gametangia are morphologically identical, flask-shaped with a single papillate exit aperture, formed from any vegetative cell. Motile cells are formed by sequential cleavages of the parent cell, and are released by rupture of the exit papilla. Sexual life history includes an alternation of isomorphic phases, with meiosis occurring at the first division of the sporangia.
