| Thallus foliose, terricolous, lignicolous or corticolous, moderately to loosely adnate, to 12 cm wide. Lobes imbricate, flat or slightly convex at the apices, becoming more strongly convex towards thallus centre, sublinear to sublirregular, 1.0-3.5 mm wide, irregularly branched; laciniae developing at periphery and within thallus, terete to subterete, ±torulose, ±subfruticose, sublinear to linear-elongate, dichotomously to subdichotomously branched, 0.3-1.0 mm wide. Upper surface dark brown to black-brown or olive-brown, paler at the thallus periphery, dull to slightly shiny at the apices, smooth or becoming rugose, lacking and isidia. Medulla white. Lower surface jet black, moderately to densely rhizinate; rhizines black, short, simple or occasionally tufted, slender; laciniae canaliculate, pale brown to black with concolorous rhizines. Apothecia common, short stipitate, 3-5 mm wide; disc concave, becoming ±flat or undulate, black-brown; thalline exciple thin, entire, rugose. Ascospores 8-9 x 5-6 µm. Pycnidia common. Conidia bifusiform, 6-8 x 1 µm. CHEMISTRY: Cortex K-, HNO3+ dark blue-green, medulla K-, C-, P-, UV-; containing divaricatic acid (major), nordivaricatic acid (trace), stenosporic acid (minor/trace). | ||
| This species is quite common in southern Australia (S.A., N.S.W., Vic. and Tas.) where it occurs most commonly on soil but also spreads on to adjacent dead wood and the lower trunk of trees. | ||
