Calycidium is a genus of lichen-forming fungi in the family Sphaerophoraceae. It has two species. It is one of the few lichen genera containing foliose (leafy) species that produce a mazaedium – a powdery mass of spores. Both species occur in Australasia and South America, where they grow on tree bark or on mosses.
