Distinguishing features of ''Xanthoparmelia nomosa'' include its narrow, more or less straight {{lichengloss|lobes}} with a black lower surface, the occurrence of both isidia and {{lichengloss|lobules}} on the thallus surface, and the orange pigmentation of the lower [[Biology:Medulla (lichenology)|medulla]]. It lacks apothecia and pycnidia. Its thallus grow 3–5&nbsp;cm wide and is yellowish-green, although it darkens with age. The isidia are initial more or less spherical, later becoming cylindrical and then coralloid with blackened tips, measuring 0.5–1.0&nbsp;mm high and 0.1–0.15&nbsp;mm wide.
