Porphyra umbilicalis, commonly known as laver, is a species of seaweed in the genus Porphyra. It is smooth in texture and forms delicate, sheetlike thalli, reaching 25 centimetres (10 in) long[1] and often clinging to rocks.[2] Porphyra is classified as red algae; it tends to be a brownish colour, but boils down to a dark green pulp when prepared. It is unusual amongst seaweeds because the fronds are only one cell thick.[3][4]
It is commonly found around the west coast of Great Britain and east coast of Ireland along the Irish Sea, where it is also known as "sleabhac" or "slake".[5][6] It is edible and used to make laverbread.[1] In some parts of the United Kingdom it is classified as critically endangered following steep decline of its population in previously established habitats.[7]
