[1] This Tasmanian species is characterised by its minimalistic appearance with very small apothecia and a thallus that is pale, sparse and areolate.

It was first described by the lichenologists Patrick M. McCarthy, John Alan Elix, and Gintaras Kantvilas based on specimens collected from coastal serpentinite rock outcrops in Tasmania, Australia.

[2] Apothecia are moderately numerous, typically black and either round or broadly ellipsoid, measuring 0.19 to 0.44 mm in diameter.

They feature a very thin proper exciple, darkening to a deep purple when treated with a potassium hydroxide solution (K).

The ascospores are dark brown, submuriform (divided into multiple internal compartments by intersecting longitudinal and transverse septa), and small, with only a few cells visible in optical section.
