Short description Morphology

Thalli bright to yellowish green. Several unbranched tubular branches arise from a short stipe; discoid holdfast. Erect branches tapering below, inflated above and constricted or contorted at certain points. Cells polyhedral in surface view, irregularly arranged and filled with spherical to oval chloroplasts.

Biology     Glossary (e.g. epibenthic)

Grows on rocky substrate in the lower intertidal to shallow subtidal zones or in shallow tidepools exposed to air during low tide (Ref. 80758); also considered as a fresh sea-vegetable (Ref. 82232). Inhabits rocky substrate in the lower intertidal to shallow subtidal zones or in shallow tidepools exposed to air during low tide (Ref. 80758). Also found in supra-littoral pools that are influenced by wave splashes (Ref. 83307) as well as sandy areas where rock attachment is possible (Ref. 801).
