Description:

I thought this was Lichina pygmaea at first, but it seems too foliose; could it be the small red alga Catanella caespitosa)? It was growing in shaded hollows on a rock face very high n the shoreline at Rhossili, Wales.

Could they be young Fucus

Could they be young Fucus plants?

Fucus?

Thanks Mark. Possibly and Fucus spiralis was growing nearby along with Pelvetia caniculata, but they were in distinct bands in more sunlit areas, whereas mats of this smaller plant were just in crevices and depresssions that got little or no direct sunlight, whuch made me think they were something else, and Catenella as a red alga with delicate pigments, does seek such locations.
