Porphyra C. Agardh 1824

With thalli of differing morphologies during life history, the larger stages leafy and erect, the smaller stages microscopic and filamentous. "Gametangial" thalli with monostromatic or distromatic blades, arising singly from discoid attachment. Blades sessile or with brief stipe, normally entire, sometimes with much-ruffled margins. Cells embedded in colorless, firm, but gelatinous matrix. Chloroplasts 1 or 2, stellate, each with central pyrenoid. Plants monoecious or dioecious. "Spermatangia" in packets of 16-128, mostly in marginal areas. "Carpospores" in packets of 4-64, usually in larger marginal areas. Filamentous "Conchocelis" stage (see below, p. 304) probably perennial, commonly growing in matrix of mollusk shells.

Porphyrella gardneri Smith & Hollenb.

Smith & Hollenberg 1943: 215; Smith 1944: 175.

Thalli mostly 2-3.5 cm tall, purplish-red, not noticeably iridescent, usually with several blades from single holdfast; blades cylindrically stipitate, oblong to lanceolate when young, cuneate to orbicular at maturity, sometimes cordate at base; cells of blade subcubical, 10-15 µm diam.; "spermatangia" in packets of about 64, in small irregular marginal patches; "carpospores"(?) released singly at margin during gelatinization of walls.

Common epiphyte on tips of blade divisions of Laminaria dentigera, less frequently on tips of leaflets of Egregia, in semi-exposed areas, Adak I., Alaska, to San Luis Obispo Co., Calif., and Pta. Banda, Baja Calif. Type locality: Pt. Joe (Monterey Peninsula), Calif.
