Sticta cinereoglauca is characterised by: the corticolous (rarely saxicolous) habit; broadly rounded lobes with entire margins without soredia or isidia; a green photobiont; frequent red to red-brown apothecia usually clustered towards the lobe margins; and characteristic 5–7-septate ascospores, 42–50 × 7–9.5 μm. It is distinguished from S. subcaperata, which has thicker, more coriaceous lobes and apothecia with distinctive waxy yellow or orange-yellow discs. The phyllidiate northern species. S. babingtonii also has 7-septate spores, but the spores in this species are longer (45–61 μm), and it also has characteristic orange, pinkish or mustard-yellow cyphellae on the lower surface.
