The provision for conserved and rejected generic names entered the botanical code of nomenclature 25 years before the type method was adopted. All conserved and rejected generic names approved by an international botanical congress prior to 1954 were applied in accordance with circumscriptions. Bringing the lists of names into accordance with the type method resulted in the finding that many names had been unnecessarily conserved, Bangia Lyngb. among them. Silva's choice of Conferva fuscopurpurea Dillwyn as generitype must be rejected in favor of Pfeiffer's previous choice of C . atropurpurea Mert. ex Roth. Bangiadulcis W.A. Nelson, based on C . atropurpurea , is thus rendered a superfluous name for Bangia Lyngb. The latter name when properly typified applies to a genus that currently comprises a single freshwater species. Generic limits remain to be established among the phylogenetically diverse marine populations currently assigned to Bangia .
