Thallus (Fig. 5F, G) grey-red to red-purple, 5–20 (–40) cm long and (2–) 4–10 (–30) cm broad, relatively tough, elongate-cuneate with undulate margins when young, becoming broadly expanded and usually umbilicate by basal proliferation, blades monostromatic, 35–60 µm thick, arising from a rhizoidal holdfast; usually epilithic or on solid substrates, rarely epiphytic. Growth diffuse, intercalary. Cells (Fig. 6A) more or less in rows but becoming irregular, isodiametric to slightly elongate in surface view, 10–15 µm across, separated by a gelatinous matrix 0.5–1 times the cell width; rhodoplasts stellate, axial, each with a pyrenoid.

Reproduction: Monosporangia (?) scattered, near margins. Thalli monoecious. Carposporangia (Fig. 6B) prominent, forming irregular patches often with interspersed vegetative cells, usually adjacent to the thallus margin, with (4–) 8–16 carposporangia per group. Spermatangia (Fig. 6B) adjacent to the thallus margin, in patches or amongst the carposporangial groups, in packets of 32–64, spermatia 2–3 µm in diameter.

Sporophyte (conchocelis phase) recorded by Conway & Cole (1977, p. 208).

Type from the Auckland Is (D'Urville); in Herb. Montagne, PC.

Distribution map based
on current data relating to
specimens held in the
State Herbarium of SA

Distribution: New Zealand and subantarctic islands, southern S. America (Pujals 1963, p. 8).

In southern Australia, from Elliston, S. Aust. to Port Stephens, N.S.W. and around Tasmania.

Taxonomic notes: P. columbina is often common, forming a dense mid eulittoral community, on rough-water rocky coasts from Robe, S. Aust. to southern N.S.W., and around Tasmania, especially in winter months.
