Quick Summary

The Teloschistales are an order of fungi that form lichens. These lichens are often found on rocks, particularly those near the sea. Their thallus, or body, can be granular and may have poorly defined, lobed margins. Notable examples within this order include the orange sea lichen and the shore lichen, also known as yellow scales. Genera within the Teloschistales include Caloplaca, Teloschistes, and Xanthoria. Lichens themselves are composite organisms resulting from a symbiotic relationship between algae or cyanobacteria and fungi.12
