Common names

(as Porphyra leucosticta Thuret)
English: Pale Patch Laver (Bunker & al. 2010).

Delicate membranous monostromatic reddish-brown fronds, becoming pink on drying, to 150 mm long, with very short stipe from basal holdfast.

Usually epiphytic on larger algae, mid-intertidaltidal to shallow subtidal, spring to autumn, widely distributed, common.
