Imshaugia aleurites (Ach.) S.L.F.Meyer
Thallus pale grey, lustrous, lobes adpressed to the substrate, surface becoming covered in grey, eroding isidia; widespread but very local, on acid-barked trees, fences and peat. Easily confused with Parmeliopsis hyperopta, which lacks isidia but has similar-looking soredia initially formed in convex soralia.
