Abstract
A revised classification is presented for the class Bangiophyceae, incorporating seven families in four orders: Porphyridiales, Erythropeltidales ord. nov., Bangiales and Rhodochaetales. The principal changes from previous schemes include: 1) a new circumscription of the two families in the Porphyridiales, based on chloroplast structure and the presence or absence of pyrenoids; 2) the delimitation of the Erythropeltidales to include the families Erythropeltidaceae, Boldiaceae, and Compsopogonaceae based on similarities in monosporangium formation; and 3) the removal of the Bangiaceae as a monotypic order. The new scheme takes into account recent observations of life histories and ultrastructure. Problems in establishing relationships within the Porphyridiales are discussed, and the need for further ultrastructural studies is emphasized.
