Ulva compressa Linnaeus
Formerly widely known as Enteromorpha compressa.
Description: Compressed, elongated, hollow fronds with a
green colour.
Habitat: Rock pools and sandy rocks, particularly in
places with widely varying salinities such as upper-shore pools
(below). Extremely tolderant to widely varying salinities and
temperatures. Bubbles of oxygen (from photosynthesis) often
apparent in the tubular fronds.
Distribution: Common through Britain and Ireland, and
seemingly world-wide.
Similar species: Ulva (Enteromorpha) intestinalis which tends to be more
tubular.
Usage: Used dried in cooking, particularly
with hens' eggs.
