Nomenclatural note
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)."
