These represent different species of lichen that have adapted to the conditions at different heights above sea level. Lichens near the top of a rocky shoreline—typically bright orange or white—do not get very wet, but do occasionally get sprayed with salt and bird droppings.

Caloplaca marina, the orange sea lichen, is a crustose, placodioid lichen. It has wide distribution, and can be found near the shore on rocks or walls. Calos in Greek means nice, placa in Greek is shield. Caloplaca therefore means ‘beautiful patches’.

Lichens occur from sea level to high alpine elevations, in many environmental conditions, and can grow on almost any surface. [16] [17] They are abundant growing on bark, leaves, mosses, or other lichens [15] and hanging from branches "living …

Disc-like, convex and deep reddish orange fruiting bodies occur on the surface of the thallus. Widely distributed around the British Isles. Gaps in its recorded distribution probably due to lack of suitable substrata. A strictly maritime species, common on hard rocks and concrete from just above high water level.

Lichens between the high and low tide marks are submerged on a regular basis but also get exposed to the sun regularly—they form the black zone. Read more about seaside lichens on our blog.

Lichen can be found in many different environments from the seashore to living on hard surfaces and trees on land. It is estimated that there are over 1,000 lichen species in Ireland. They also are widely distributed around the world from the artic to tropical regions.

We have included in our list (i) strictly 'marine' lichens, corresponding to those subjected to tides in the littoral zone, (ii) 'maritime' lichens living in a narrow coastal zone directly subjected to sea water projections and sea spray, also called supra-littoral zone.
