The type of Ulva laciniata Lightfoot, the basionym of P. laciniata (Lightfoot) C. Agardh, is an Erythroglossum (Delesseriaceae) and this entity is now known as Erythroglossum lacinatum (Lightfoot) Maggs & Hommersand (1993: 219). From C. Agardh (1824) onwards, however, it was widely regarded as a species of Porphyra. According to Brodie & Irvine (2003: 111), most records of P. laciniata represent Poprhyra dioica but further south other species may be involved. Wynne (2010: 34) comments: "Part of what had been mistakenly called P. laciniata in the British Isles is now called P. dioica J.Brodie & L.M.Irvine (Brodie & Irvine 1997), and part is now assigned to P. purpurea (Roth) C.Agardh (Brodie & Irvine 2003)."
This is a marine species.
Japanese: Hoshinori, Asakusa-nori, Asakusa nori (Kirby 1953).
