Thallus orbicular to spreading, loosely to closely attached, 5-10(-15) cm diam., corticolous. Lobes broad, rounded, 0.5-2.5 mm wide, imbricate, folded, margins entire, sinuous or slightly notched or incised, often ± ascending at periphery. Upper surface bluish-grey to olive-greenish, often suffused-brownish especially towards apices, smooth, coriaceous or minutely wrinkled, rather papery. Lower surface pale buff to brown, ± densely tomentose from margins to centre, tomentum long, silky, white. Cyphellae white, scattered, 0.2-2.0 mm diam., with a conspicuous, raised margin. Apothecia frequent, clustered towards margins of lobes, sessile or subpedicellate, 0.2-3.0 mm diam., disc red or reddish-brown, matt, rarely glossy, plane to convex, margins pale, thin, often excluded at maturity, yellowish-buff or flesh-coloured, subcrenulate or denticulate. Ascospores 5-7-septate, elongate-ellipsoid, apices pointed, 36-58 × 5-7 µm.
N: Three Kings Is, to Wellington. Mainly coastal and lowland on trees and shrubs, most commonly collected in coastal sites north of Auckland.
Endemic
S. cinereoglauca is distinguished from S. subcaperata by the thinner, generally smaller thallus which has a distinctly papery texture, and by the mainly submarginal apothecia with reddish-brown and not orange or orange-yellow discs. It is most commonly collected from northern coastal forest north of Auckland and is widely represented in mid-nineteenth century collections from the Bay of Islands where it appears to have been first collected. It is illustrated in Babington [ loc. cit., tab. CXXVII fig. C (1855)]. The 5-7-septate spores also distinguish it from all other species of Sticta in New Zealand. S. suborbicularis Müll. Arg., from Queensland is similar but has 1-septate spores.
