Type: Australia, Queensland, Mackay, Blacks Beach, 1979, Stevens 3129NS (MEL! - holotype; evernic acid, lecanoric acid and usnic acid).
Thallus: Saxicolous, pale yellow-green, small, caespitose, rigid, 0.5 - 2.0 cm high; branching subdichotomous to irregular, small branchlets or spinules arise laterally from the main branches; branch width 0.2 - 1.0 mm, subterete to terete or rarely flattened, narrow, apices pointed, fragile; surface shiny to matt, without pseudocyphellae, smooth; holdfast diffuse; soralia absent. Apothecia common, marginal or lateral below the apices, disc 1.0 - 2.0 mm diam., plane; margin thin to very thick; spores small, oval or ellipsoid, straight, 8 - 12 x 4 - 4.5 µm.
Photobiont:
Chemistry: Evernic acid (M), lecanoric acid (t), ± sekikaic acid (t), and usnic acid.
Ecology: This saxicolous species has been collected from coastal cliffs, composed of a variety of rock types (granite, siltstone, slates, rhyohtic, breccia, and tuff) indicating it is not substrate specific. Only small colonies grow on the cliff faces, usually at 10 - 20 m above beach level; although on Lizard Island (14°S, the most northern collection) a specimen was collected at 360 m elevation.
