Ganonema is a genus of red algae, from the Liagoraceae family, characterised by its dichotomously branched, multiaxial thalli, with terete axes." It is closely related to Liagora, but can be distinguished in two important respects. Its vegetative structure is distinct, as the basal cells of its cortical fascicles are isodiametric, whereas the cells of Liagora are elongate. Also, its reproductive development features "the occasional production of carpogonial branches in clusters and the production of spermatangia in dense heads."

Dotyophycus is a genus of red algae, from the family Liagoraceae, characterised by a "terete, dichotomously divided, calcified thallus." It can be recognised by its reproductive features, particularly the gonimoblast that follows fertilization and the absence of sterile cells in mature cystocarp. Visually it is distinguished by its "almost creamy-white" appearance derived from its outer mucilage and calcification.
