The Rhodogorgonales are an order of red algae, a sister group to the corallines. They are always thalloid and calcified; their calcification is very different from the corallines, as individual calcite crystals are deposited in the cell wall of specialised cells; this suggests that the evolution of calcification may have been independent from the corallines.[2] They have no fossil record.[3]
Unlike the corallinales and sporolithales, their closest relatives, these thalli are loose aggregations of hair-like cells, with the middle portion formed of rhizoid-like filaments. Spores are borne on the end of hair-like cells (cortical fascicles).[4]
