The upper littoral fringe in the moist dark conditions inside caves on soft rock may be characterized by velvety bands of the red alga Rhodothamniella floridula. In chalk caves, on the east and south-east coast of England, a distinctive assemblage of species occurs, including the brown alga Pilinia maritima and the bright green alga Pseudendoclonium submarinum which often covers the roofs of chalk caves. Where the rock is sufficiently hard, the crustose red alga Hildenbrandia rubra may occur on the cave roofs.
