Specimen above found on uppershore rock armour with Porphyra linearis at Chyandour Rocks, Penzance, Cornwall. 27.01.15.

I am very grateful to Professor Juliet Brodie for identifying the specimen above and the additional advice she gave regarding the genus Porphyra. Question marks are placed beside some of the image labels, this is because the details were interpreted from images.

Scientific and European Names:
Porphyra umbilicalis, Tough Laver, Purple Laver, Nori, Laver, Navelwier, Purperwier, Porphyre.

AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
