Unidentified species of brown algae (?). Similar to sea cauliflower (Leathesia spp.) but some specimens are distinctly globular (like the globose stage of Derbesia spp.). Possibly several species or stages. Possibly Soranthera spp. (?) although many do not appear to have the distinct studs that give them the name "studded sea balloon". Possibly several species.
