Physcia millegrana, commonly known as the mealy rosette lichen, is a species of corticolous (bark-dwelling), foliose lichen in the family Physciaceae. It is common in the eastern United States. It was formally described as a new species in 1940 by the lichenologist Gunnar Degelius. This gray lichen with a pale underside is characterized by its coarse soredia (granular vegetative propagules) that are densely distributed the margins of lobes, giving them a somewhat ruffled appearance.
