Morphology: blade one cell thick, ovate. Margins slightly ruffled. Stipe inconspicous. In one speci- men, male gametangial and zygotosporangial each on a separate lobe of the thallus, and diviđeđ from margin to holdfast. Other details of reproduction are unknown. Male gametangial sori yellowish- white. Zygotosporangial sori red. Herbarium specimens: brown purple, adhering well to paper. Porphyra sp. 2 (Fig. 4) Station: 1781. Remarks: collected in August. Littoral. Morphology: blade one cell thick, ovate. Margins with some ruffles. Stipe inconspicuous. Male gametan- gial and zygotosporangial sori as in P. leucosticta, but male gametangial patches larger and more elongate. Herbarium specimens: purple brown, adhering well to paper. Porphyra sp. 3 (Fig. 4) Station: 1126. Remarks: collected in June. Littoral. Morphology: blade one cell thick, ovate but dividing into 2 lobes. Margins ruffled. Stipe inconspicuous. Male gametangial sori as in P. leucosticta, but patches very pale and tending to blend with the rest of thallus. Herbarium specimens: very pale brown (straw), adher- ing well to paper. Porphyra sp. 4 (Fig. 4) Reference: Brodie and Irvine (2002), Kommann and Sahling (1991, as P. insolita. Kornmann & Sahling) Stations: 1046, 1174, 1184, 1280, 1281, 1297, 1305, 1346, 1347, 1348, 1352, 1353, 1354, 1358, 1362, 1363, 1683, 1684, 1685, 1686, 1687, 1688, 1689, 1690, 1691, 1692, 1693, 1695, 1696, 1697, 1701, 1702, 1703, 1721, 1738, 1768, 1770, 1773, 1775, 1779, 1780, 1781, 1911, 1913. Littoral to 1 m depth. Remarks: collected in January and April-October. Morphology: blade one cell thick, broadly ovate to um- bilicate (as with a naval). Margins ruffled. Stipe in- conspicuous. Male gametangial and zygotosporan- gial sori in broad marginal band, appearing on sep- arate or on the same individual. When on the same individual, then separated by a line from the mar- gin to the holdfast. Male gametangial sori pale yel- low; zygotosporangial sori bright red. Herbarium specimens: dark purple, adhering quite well to paper. Porphyropsis COCCÍnea (J.Agardh ex Aresch.) Rosenv. (Fig. 3) Porphyra coccinea J.Agardh ex Aresch.
