It belongs to the genus Verrucaria, a group of lichens characterised by their small, flask-shaped fruiting bodies (perithecia) and crustose growth form.

Its unique genetic profile, based on internal transcribed spacer sequence analysis, sets it apart from other known Verrucaria species.

[2] The thallus (lichen body) of Verrucaria fuscozonata is pale grey and primarily endolithic, meaning it grows within the rock substrate rather than on its surface.

Its apparent preference for dolomite substrate in a riparian environment suggests it may have specific ecological requirements, though more research is needed to confirm this.

The species' rarity and limited known distribution make it a subject of interest for further lichenological surveys in Finland and potentially in neighbouring regions with similar geological features.
