In the wake of worldwide coral bleaching, studies have suggested that the endolithic algae located in the skeleton of the coral may be aiding the survival of coral species by providing an alternative source of energy.

For example, three species of land snails in the genus " Euchondrus " in the Negev desert are noted for eating lichens growing under the surface limestone rocks and slabs ( endolithic lichens ).

Although the role that endolithic Fungi play is important in coral reefs, it is often overlooked because much research is focused on the effects of coral bleaching as well as the relationships between coelenterate and endosymbiotic symbiodinia.

Endolithic organisms have also been found in surface rocks in regions of low humidity ( hypolith ) and low temperature ( psychrophile ), including the Dry Valleys and permafrost of Antarctica, the Alps, and the Rocky Mountains.

Crustose lichens that grow on the rock are epilithic, and those that grow immersed inside rock, growing between the crystals with only their fruiting bodies exposed to the air, are called "'endolithic lichens " '.

""'Lecidea laboriosa " "'is a species of lichen that grows inside solid rock ( endolithic ), with only the small black disc-like fruiting bodies ( apothecia ) visible above the rock surface.

It is best known as a material for gramophone records produced in the UK by Crystalate Manufacturing Company ( although Burt's own US-based Globe Record Company also manufactured Crystalate records ), and for moulded billiards, pool and snooker balls, as produced by the Endolithic Company ( UK, later the Composition Billiard Ball Company ).
