Stictina weigelii var. sublimbata Steiner, Bull. Herb. Boissier sér. 2, 7: 642 (1907).
Thallus loosely attached, ± orbicular to irregular, 2-8 cm diam., corticolous. Lobes rounded, 3-10 mm wide, undulate, ± imbricate centrally, margins free, thickened, crisped, ± ascending, entire or with eroding, linear soralia on lower surface. Upper surface dark grey-blue or blackish, minutely white-maculate (×10 lens) or with irregular white or brownish, algal-free patches, greyish brown when dry, matt, shining, rather coriaceous. Soredia bluish-grey, coarse, granular, in linear soralia often eroding back from margins of lower surface. Medulla white. Photobiont blue-green. Lower surface pale brown at margins, dark brown or black towards centre, ± uniformly thick-tomentose to margins. Cyphellae conspicuous but rather few, scattered, round to irregular, sunk in tomentum, 0.1-2.0 mm diam., white, with a conspicuous, pale, raised rim. Apothecia not seen.
S: Canterbury (Lewis River near confluence with Nina River, Hanmer State Forest). On bark of divaricating shrubs in humid situations. Still very rarely collected.
?Palaeotropical
Distinguished from S. limbata by the lack of soredia on the upper surface and the irregular to imbricate lobes which are not monophyllous.
