Electronic Flora of South Australia Family Fact Sheet
Phylum Rhodophyta – Class Bangiophyceae
Thallus unicellular or with cells embedded in a mucilaginous sheath as amorphous or pseudofilamentous colonies, uniseriate to multiseriate, basal attachment cell not differentiated. Rhodoplasts single and stellate with a central pyrenoid, or one to few, discoid to lobed, without pyrenoids.
Reproduction: Reproduction by cell division, release of vegetative cells, or by endospores.
Taxonomic notes: An order of two families, the Porphyridiaceae and the Phragmonemataceae, the latter unknown from southern Australia. The order is characterised by its essentially unicellular or colonial form, in the latter case with the cells embedded in a mucilaginous sheath and arranged somewhat irregularly, not as a filament of closely adjacent cells with juxtaposed common walls.
