Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was established in 1994 to accommodate several Australasian lichens that form crusts on wood, bark, and rock surfaces, and it was named in honour of the German mycologist Gerhard Rambold. These lichens are characterised by their small, disc-shaped fruiting bodies and their chemical composition, which includes β-orcinol derivatives and sometimes anthraquinones, though they lack the distinctive crimson reaction found in the related genus Pyrrhospora. The genus contains about 40 species found worldwide, ranging in
