Found in Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins.

The type specimen was collected in the Namtok Phlio National Park (Chanthaburi Province); here, in a moist evergreen forest at an elevation of 100 m (330 ft), the lichen was found growing on the bark of Anisoptera costata.

[1] The lichen has a smooth and shiny, olive-grey thallus with a dense cortex, a continuous algal layer and a white medulla.

Its apothecia are about 0.7 mm in diameter with a white-rimmed, round pore and carbonized (blackened) exciple.

The ascospores are ellipsoid, thin walled and brown, and typically measure 11–13 by 6–7 μm.
