Amandinea lecideina is characterised by: the saxicolous habit; sessile apothecia; ascospores (Dubyana -type, not constricted at septum), 12–16 × 6–8.5 μm; and the abundant pycnidia. It differs from A. punctata by the median spore wall thickening, the cracked thallus, its ecology (coastal rocks) and by the more frequent occurrence of pycnidia.
