This species can easily be confused with similar lichens, but it can be distinguished by its specific morphological and chemical features.

The species name, verrucosa, is derived from the Latin word for "warts" and refers to the wart-like appearance of the lichen's thallus.

The type specimen was collected from tree bark in Cát Tiên National Park, Vietnam, in December 2015.

The presence of psoromic acid, muriform ascospores, and the olive-green, verrucose thallus help to distinguish this species from similar lichens.

[2] Acanthothecis verrucosa is native to the tropical forests of Cát Tiên National Park in southern Vietnam.
