The lichen occurs in Papua New Guinea, and is known from only two specimens collected at the type locality.

The type was collected in Varirata National Park at an altitude of 800 m (2,600 ft), where it was found growing on conglomerate rock.

[1] The lichen has a dull fawn, thick, crustose thallus that is cracked and areolate (divided into small, usually rounded to polygonal to irregular areas).

Between two and four point-like, black ostioles (pore-like openings through which the spores escape) are on each apothecium.

They invariably number four per ascus, in contrast to some other Pertusaria species found in the same country, which may occasionally have asci with three or five ascospores.
