Summary

Description

Ulva linza is a large, ribbon-like species of green seaweed that may reach up to 30 cm in length. The thalli are unbranched and often have a frilled margin. The thalli taper into a distinct stipe below and are highly compressed. The width of the thallus is greater in the middle than at the base and may reach 5 cm in width. Ulva linza is bright light to dark green in colouration.
