“…This species is not the common, epilithic, intertidal crust that is described and illustrated in Chamberlain and Irvine () and in Cabioch and Boudouresque (), or online in Bressan et al. () (http://www2.units.it/biologia/Corallinales/home.html, accessed 27 February 2015). Instead, it is a mostly subtidal to occasionally low intertidal species usually found as a rhodolith, but may also be epilithic, epizoic or epiphytic (Table S2).…”

DNA sequences from type material in the nongeniculate coralline genus Lithophyllum were used to unambiguously link some European species names to field-collected specimens, thus providing a great advance over morpho-anatomical identifi-cation. In particular, sequence comparisons of rbcL, COI and psbA genes from field-collected specimens allowed the following conclusion: the generitype species, L. incrustans, occurs mostly as subtidal rhodoliths and crusts on both Atlantic and Mediterranean coasts, and not as the common, NE Atlantic, epilithic, intertidal crust reported in the literature. The heterotypic type material of L. hibernicum was narrowed to one rhodolith belonging in Lithophyllum. As well as occurring as a subtidal rhodolith, L. hibernicum is a common, epilithic and epizoic crust in the intertidal zone from Ireland south to Mediterranean France. A set of four features distinguished L. incrustans from L. hibernicum, including epithallial cell diameter, pore canal shape of sporangial conceptacles and sporangium height and diameter. An rbcL sequence of the lectotype of Lithophyllum bathyporum, which was recently proposed to accommodate Atlantic intertidal collections of L. incrustans, corresponded to a distinct taxon hitherto known only from Brittany as the subtidal, bisporangial, lectotype, but also occurs intertidally in Atlantic Spain. Specimens from Ireland and France morpho-anatomically identified as L. fasciculatum and a specimen from Cornwall likewise identified as L. duckerae were resolved as L. incrustans and L. hibernicum, respectively.

“…Many species that are common in the Mediterranean were described in the late eighteenth and early nineteenth centuries (Ellis, 1768;Ellis and Solander, 1786;Esper, 1796;de Lamarck, 1801;Bory de Saint-Vincent, 1832). The subsequent work carried out until the 70s−80s of the twentieth century consisted mainly of paleontological studies, floristic inventories, traditional taxonomy based on morphology, and descriptive distributional and ecological studies (Bressan, 1974;Bressan and Babbini, 1995, and references therein). Most ecological studies had in fact a general perspective and concerned coralline-dominated habitats (mainly coralligenous concretions and Lithophyllum byssoides rims), rather than coralline biology itself.…”

“…e maerl corallines form nonnucleated rhodoliths, of the unattached branches category (Bosellini & Ginsburg 1971;Bosence 1976;Basso 1998;Birkett et al 1998;Basso et al 2009). Mediterranean maerl has been identified to 65 m (Huvé 1956;Jacquotte 1962;Babbini et al 2006) and coralline biodiversity is greater than that of most Atlantic and Pacific analogues (Birkett et al 1998;Riosmena-Rodríguez et al 1999;Bressan et al 2001;Peña & Bárbara 2006;Babbini et al 2006;Giaccone et al 2009). e recent use of acoustic surveys techniques for seafloor mapping and remotely operated vehicles (ROVs) revealed recently the presence of maerl beds off the island of Ischia (Budillon et al 2003;Gambi et al 2009).…”

On the continental shelf off the Cilento peninsula (eastern Tyrrhenian Sea) the occurrence of more than 13 km 2 of maerl beds was documented through acoustic surveys. Swath bathymetric data along with a dense grid of chirp-sonar profiles were acquired over more than 180 km 2 . e maerl facies was characterized on the basis of the components analysis of 32 grab samples collected at selected sites. Mapped maerl-beds are predominant on submerged terraces located at variable water depth (wd) between 42 and 52 m. is preferred distribution on submerged terraces is probably associated with relatively vigorous bottom currents generated by local circulation that hinders the deposition of terrigenous sediments. Calcareous red algae result to be the most important producers of carbonates from 40 down to 60 m wd. We calculated the coralline carbonate accumulation from the percentage cover of coralline algae (thin section mapping) × 1 cm-thick layer of sediment × measured coralline density. e total coralline cover (living plus dead) in the Cilento area is 13.96 km 2 , with a total 316 800 tons of algal carbonate in the surface 1 cm layer, that correspond to 20 430 g m -2 . Living maerl is recorded at a depth of 47 m, with a live coralline
