Summary

Description

An encrusting yellow-orange to bright orange lichen. The thallus is composed of small granules or 'islands' of tissue but is never powdery. When well developed the crust may be composed of small convex islands of tissue often with a paler edge. Disc-like, convex and deep reddish orange fruiting bodies occur on the surface of the thallus.

Recorded distribution in Britain and Ireland

Widely distributed around the British Isles. Gaps in its recorded distribution probably due to lack of suitable substrata.

Global distribution

-

Habitat

A strictly maritime species, common on hard rocks and concrete from just above high water level.

Depth range

-

Identifying features

  • Thallus granular, orange to orange red in colour but never powdery.
  • Fruiting bodies disc-like, convex and deep reddish orange.
  • Marginal lobes not clearly defined.
  • Strictly maritime at or above high water.

Additional information

Caloplaca marina is one of several species of Caloplaca found on rocks at or above high water. Caloplaca thallincola may occur at the same position but prefers sheltered conditions. Caloplaca thallincola is a lighter orange with a distinct lobose margin. Caloplaca maritima is also similar but is never orange and the thallus is composed of more convex, paler, wax-like islands of tissue. Identification to genus or species level may require simple chemical tests; for details see Dobson (2000).
