Lithothamnion corallioides

Range & Status

Commonly found as unattached, profusely-branching, pinkish-red rhodoliths with blunttipped branches and as small fragments. More rarely found as attached, protuberant thalli on shells. Quite common in some locations in southern Britain and western Ireland. Large amounts of intact rhodoliths are present on the St. Mawes ' bank' side of the Falmouth Harbour and equally large amounts of fragmented thalli in Falmouth Bay. Smaller amounts have been recorded in the Helford Estuary, off Pedngwinian on the west side of The Lizard and at Porthgwarra and Sennen Coves in West Penwith. This species has suffered from ma\'ebrl\endash dredging operations in the Falmouth area in the past. It requires clean, clear, warm and sheltered water and is found in the lower intertidal to shallow subtidal. This species is on the UK List of Priority Species (2007).
