''Coccotrema maritimum'' is a crustose lichen commonly known as volcano lichen, due to the volcano-like appearance of the fruit bodies. It was first described and named by Canadian lichenologist Irwin Brodo from a population on the Queen Charlotte Islands in 1973. == Description == The thallus (the main body of the lichen) is thick, rough and crusty, taking on the appearance of dry, cracked mud. It is white to pinkish or yellowish-gray in colour, and porous to allow for gas exchange. From a distance, ''C. maritimum'' can be seen on the rocks as a white line just above the surface of the water. The outer surface of ''C.maritimum'' is scattered with hemispherical nitrogen-fixing structures (cephalodia) that are pinkish to brownish–grey in colour. 〔
