EMENDED DESCRIPTION

Gametophyte blades linear, 10-60 mm high and 3-20 mm wide, with an irregular undulate margin, with linear to pear shaped on the base. Holdfast clearly separated from the thallus; colour red to brown on outer edges. Dioecious, occasionally monoecious; reproductive structures marginal; dark red zygotosporangia and female sorus on the base of the blade, winter seasonality, on rocks, high littoral, very wave exposed area, and distinct rbc S- rbc L spacer sequences.

NOTE

Designation of a lectotype for Porphyra linearis Greville from a specimen from Sidmouth at E by Brodie & Irvine (2003: 124) was not valid as the phrase “designated here” or an equivalent was not used as required after 1 January 2001 (Art. 7.11; Turland et al. 2018). We here designate formally the same specimen (‘Sidmouth, Spring’, E!) as lectotype.
