Candelariella flavosorediata is a species of lichen in the family Candelariaceae. Found in Réunion, it was described as a new species in 2021 by lichenologists Klaus Kalb and André Aptroot. The type was collected just below the summit of the Maïdo (a volcanic peak), at an elevation of about 2100m (6,900feet). Here it was found growing on tree bark in scrub. The specific epithet flavosorediata refers to the yellow soredia that cover most of the lichen thallus.
