Description.

Thalli linear to lanceolate, base cuneate; 28-65 mm thick; to 1.2 cm wide and 16 cm long; color uniform throughout the thallus except for reproductive areas: dusky rose. Thalli dioecious. Spermatangia in packets 2 × 2 × 8. Zygotosporangial thalli not observed Habitat: very high intertidal, above Pyropia lanceolata and Pyropia montereyensis when they co-occur. Phenology: Winter to early spring. Distinguished from other species of Pyropia by unique rbc L and 18S rRNA gene sequences.

Holotype.

Saxicolous in the uppermost intertidal, above Pyropia lanceolata , northeast side of Morro Rock, Morro Bay, California, USA (35°22.29'N 120°51.98'W), J.R. Hughey, 04 Apr 2012, UBC A90634. GenBank sequences KP904006 (rbc L), KP903909 (SSU).

Etymology.

This species is named for its basal position in the phylogeny of the Pyropia lanceolata complex.

Distribution.
