Fuscidea is a genus of crustose lichens in the family Fuscideaceae. It has about 40 species. The genus was established in 1972 by Volkmar Wirth and Antonín Vězda, with its name derived from the Latin for 'brown', referring to the typical colouration of these lichens. Species of Fuscidea grow almost exclusively on acidic, silica-rich rocks, favouring steep faces in humid, high-rainfall regions such as Atlantic coastlines and mountain ranges. They form cracked or patchy crusts that spread over a characteristically dark underlying margin, often creating mosaic-like patterns where neighbouring col
