✦ Synopsis
Traditional morphological features have formed the basis for distinguishing species of Porphyra . Among these features are number of cell layers, number of chloroplasts per cell, arrangement of reproductive structures on the thallus, and overall morphology . Chromosome number and chromosome morphology have helped corroborate some species identities . A survey of northeast Pacific species of Porphyra using starch gel electrophoresis of 15 soluble proteins has shown that electrophoretic banding patterns provide a reliable diagnostic tool for species identification . Data from starch gel electrophoresis are presented to confirm the identities of species formerly associated with the Porphyra perforata species-complex in British Columbia and northern Washington . Porphyra abbottae, P . fallax, P . kanakaensis, and P . torta are recognized as distinct species, and Porphyra sanjuanensis is synonymized with P. perforata .
