Origin of Species Name
Adjective (Latin), chalky, limy (Stearn 1973).
This is a marine species.
Fragile, reddish-violet, branched, calcareous fronds; branches 2-3 mm diam.; very variable in form and difficult to identify with certainty; commonest form resemble stag's horns of irregular diameter.
Free-living in clear, clean water from 0-25 m, occasionally to 32 m, forming extensive beds of live and dead material, particularly where there are subtidal currents. It is the main constituent of maërl. Widely distributed, abundant. SW England (Cornwall), SW and W Ireland (notably Bantry Bay and Galway Bay), N to Shetland. In a few areas on the W coast of Ireland, beaches almost entirely composed of dead fragments of maërl are found; perhaps the best-known of these is Trá an Dóilín near An Chéathrú Rua (Carraroe) and several at Ballconeeley in Co. Galway.
