Status of name
This name is currently regarded as a synonym of Porphyra purpurea (Roth) C.Agardh
Type locality: Ireland (Kützing 1843: 383). Lectotype: Shuttleworth; 1831; rocks in intertidal. L (Brodie & Irvine 2003: 130). Notes: Shuttleworth is known to have been in Renvyl, Co. Galway in 1831 and 1832 (Dictionary of National Biography, vol. 18, p. 176). He appears to have sent several Irish specimens to Kützing. DNA from the lectotype in L indicates that this entity is synonymous with Porphyra purpurea (Brodie & Irvine, 2003: 130). The material was collected from rock at Crump Island, Renvyle in 1831.
Origin of species name
Adjective (Latin), amethyst, violet, also applied to the colour range between purple and violet (Stearn 1973).

Requires further investigation. Included by some in Porphyra amplissima.
According to Guiry (1997) there is some doubt about the British Isles records, and it is suggested that they require reinvestigation.
This is a marine species.
