Pannoparmelia angustata is a rather variable species. Individuals in full sunlight are distinctly yellow (usnic acid), whereas shaded forms lose usnic acid in the upper cortex and become pale greenish grey. Pycnidia are always present on the upper surface although their numbers vary considerably. Prothallus (spongiostratum) colour varies from pale yellow-tan to dark brown-black. It is distinguished from P. wilsonii by the absence of isidia.
