Xanthoparmelia plittii

Xanthoparmelia plittii grows to around 4-10 cm in diameter with irregularly lobate lobes which are approximately 0.5-2 mm wide. The upper surface of the lichen is yellow-green, with cylindrical isidia. The lower surface is pale or medium brown in color with moderately to densely packed rhizines anchoring the lichen to the surface.{{Cite journal |last1=Hutten |first1=M. |last2=Arup |first2=U. |last3=Breuss |first3=O. |last4=Esslinger |first4=T.
