Species Information

General:
Common Name: The Speckleback Lichens. Suggested by the presence of pale, speckle-like pseudocyphellae over the upper surface. Medium to large stratified foliose lichens, corticate above and below, sorediate, lobes loosely appressed, short, averaging to 3–7 mm wide, thin. Upper surface greenish yellow, pseudocyphellate. Lower surface blackening toward thallus centre, shiny, bearing short, simple rhizines. Medulla white. Photobiont green.

Flavopunctelia was formerly treated within Parmelia. For points of distinction with similar species in other genera, see the descriptions under Platismatia.
