(About 90: 1). Fructifying specimens with ripe plurilocular sporangia were collected in the area of the sea with shallow water behind Long Reef at Christianssted. As described by Mitchell in Murray „Phycological Memoirs', Part II, p. 53 the plurilocular sporangia occur in dense groups scattered over the whole surface of the thallus being formed round the depressed groups of hairs.
