Pertusaria pseudocorallina (Lilj.) Arnold forme maritime à isidies rouges.
This form has numerous pink, wine-red, ochre-pink, red isidia and sometimes, in areas very exposed to the sun, a pink, wine-red thallus (especially the margin). This very spectacular form, visible from afar, occurs on the rocks at the level of the Hydropunctaria maura s.l. zone and a little above, always in the area subject to seawater splashes. It is relatively common, especially in the Atlantic and Channel islands, and also in the Capes.
