Lepraria lobificans is a sterile, shade-tolerant species formed of grey-green, cottony granules. There are no discs. The fluffy, faintly lobed character of the crust which, when teased apart, reveals a whitish underlayer (medulla), distinguishes it from lookalikes. It is common on trees, especially ash and sycamore, as well as on natural and artificial rock surfaces — vertical mostly.

Key characteristics

• Powdery-fluffy thallus of cottony granules with a whitish underlayer
• The grey-green colour and the apparent marginal lobes, serve to indicate this species.
