Desmarestia viridis is a species of brown algae found worldwide. Its common names include stringy acid kelp, green acid kelp, sea sorrel and Desmarest's green weed. The light brown thallus is delicate with a disc-shaped holdfast. It releases sulfuric acid when damaged, destroying itself and nearby seaweeds in the process. They are found in shallow intertidal areas.[1][2][3]

Description

This brown marine algae grows solitary to 2m long. It is densely branched. The branches are terete and grow from a bulbous holdfast. The main axis is distinct and grows is 1 mm wide, the final branches fine and hair-like.[4]

Habitat

D. viridis is generally epilithic in shaded places in the lower littoral.[4]
