Authority: (Harvey) M.J.Wynne

Thallus is light to dark brown with numerous radially arranged flattened lateral branches, which are somewhat curled at the ends and hollow. This species has a distinctive, perennial, crustose base up to 5 cm (2 in) in diameter and erect axes up to 35 cm (14 in) tall that die back in the fall.

Habitat

This species occurs in the mid to low intertidal on rock and prefers semi-protected to exposed habitats. The epiphyte Saundersella simplex is frequently attached to the central axis and can nearly obscure its host.
