This small, grey, foliose lichen will be among the first species the beginner will find on nutrient-rich twigs and branches. The loosely attached plants often grow abundantly in scattered patches. The slightly raised, white-dotted lobes terminate in open clusters of soralia (coarse granular powder that is a mixture of fungal hyphae and algae). White, whiskery cilia grow along the margins. The lobe ends are never swollen or hood-shaped. Fruiting discs are uncommon.
