[2] Graphis flavopalmicola is crustose lichen with a thallus that is continuous and smooth to slightly wrinkled (rugulose), and it measures between 75 and 100 μm in thickness.

These structures are erumpent, breaking through the surface, and are typically unbranched, although occasional dichotomous (forked) or trichotomous (three-way) branching can occur.

The exciple, which is the rim or wall surrounding the apothecia, is basally closed and fully carbonised, appearing dirty brown in thin sections and containing hyaline crystals.

The hymenium, which is the fertile spore-bearing layer, is hyaline (transparent and colourless), not inspersed (not containing oil droplets), and measures 75 to 140 μm in height.

The paraphyses, or sterile filaments among the spores, are hyaline, thread-like (filiform), unbranched, dense, and moderately club-shaped (clavate) at the tips, which are yellowish-brown and 1 to 1.5 μm thick.

[2] Graphis flavopalmicola is identified by its smooth to slightly wrinkled whitish-grey thallus, which glows pale yellow under UV light, an exposed blackish disc, entire labia, a fully carbonised exciple, and small transversely septate ascospores.

Graphis stipitata is distinguished by a laterally carbonised exciple, slightly smaller ascospores (15–20 μm long), and the presence of both norstictic acid and lichexanthone.
