The type specimen of this lichen species was found in the Forqueta locality in Maquiné (Rio Grande do Sul, Brazil), at an elevation of 308 m (1,010 ft).

[2] A crustose lichen, Graphis suzanae is characterised by its smooth to irregular surface, appearing in a greyish-white hue, often devoid of soredia and isidia.

Distinguishing features of the species include an excipulum that is laterally carbonized, a clear hymenium, and ascospores that are hyaline, transversely septate, and typically measure 40–44 by 8–10 μm.

[2] At the time of its original publication, Graphis suzanae had only been recorded in two locations, Maquiné and Caraá, situated within the state of Rio Grande do Sul, southern Brazil.

In these places it occurs on tree bark within early successional stages of the Atlantic Forest, a region known for its subtropical humid climate.
