The type specimen was collected from Khlong Plou, Kapou Kapiang station (Uthai Thani province).

Instead of making discrete sexual reproductive structures like apothecia, this lichen instead has an "ascigerous zone", a region on the thallus where asci (spore-bearing cells) are located.

This zone, slightly elevated in comparison to the rest of the thallus, has a roughly circular to irregular outline, and is covered with white pruina.

When the ascigerous zone is abraded, conspicuous black spots are revealed–these are the asci, which are pyriform (shaped like an inverted pear).

The ascospores, which number 6 to 8 per ascus, are muriform (divided into compartments or locules by intersecting longitudinal and transverse septa), and measure 50–65 by 22–29 μm.
