[4] In 2016, María Prieto and Mats Wedin transferred the taxon to the newly circumscribed genus Pseudothelomma.

He described the thallus as determinate, forming either rounded or oval patches, or spreading extensively, composed of thick areoles with surfaces of many small nodules, creating a deeply fissured, chinky crust of whitish or ashy-grey colour, not reacting to KOH or CaCl2 tests.

The apothecia were noted to be innate in swollen warts, varying in size from small to large, with a black disc and a thick, white, often concealed margin.

Herre highlighted its distinctively long, slender paraphyses, a broader thecium base marked by a wide, brown-black band, and bilocular, strongly constricted spores with an oblong-ellipsoid shape.

The lichen was noted for leaving black marks on the fingers when touched, a characteristic shared with other species within the original genus Cyphelium.
