Rhizocarpon oederi is a crustose lichen historically recorded on siliceous rocks across parts of Europe and North America. It is now classified as Extinct (EX) on the IUCN Red List, representing one of the few lichen species confirmed to have been lost. Its disappearance is attributed to habitat destruction, air pollution, and the very specific microhabitat requirements that made it vulnerable.
