The lichen was first formally described as a new species in 2016 by the lichenologists Ivan Frolov, Oleksandr Khodosovtsev, and Jan Vondrák, who placed it in the genus Caloplaca.

The type specimen was collected near Gaziköy in a small brook valley at elevations of 20–40 m (66–131 ft) above sea level.

[4] This species of Pyrenodesmia is recognized by several key features: it lacks anthraquinones (common in the family Teloschistaceae), and its thallus, which is usually thinner than 200 μm, does not have a distinct cortex and has a Sedifolia-grey colouration.

The mature apothecia are typically smaller than 0.5 mm in diameter, with a black disc with a true, zeorine exciple.

[3] Chemical tests reveal that the thallus and apothecia are negative for potassium hydroxide (K), calcium hypochlorite (C), and p-phenylenediamine (P) reactions and are not fluorescent under ultraviolet light.
