Parmelia is a genus of medium to large foliose lichens.[2]: 78  The ends of the leaf-like lobes are often squarish-tipped.[2]: 78  The upper surface is pale bluish-gray to light brown in direct sunlight, with a network web-like ridges and depressions.: 78  The lower surface is black and has rhizines anchoring it to the substrate.[2]: 78 

It has a global distribution, extending from the Arctic[3] to the Antarctic continent[4][5] but concentrated in temperate regions.[6] There are about 40 species in Parmelia.[7] It is a foliaceous lichen, resembling a leaf in shape. In recent years, the genus Parmelia has been divided into a number of smaller genera according to thallus morphology.

Description and ecology

In general, Parmelia have a dark lower side with rhizines ('rootlets') which attach the lichen to its substrate. The upper side may be several colours - grey, yellow, brown - and may have reproductive organs on it. These may be apothecia (spore producing bodies), isidia or soralia (both vegetative structures). In between these two layers is the medulla which contains the algal component of the lichen.

Parmelia lichens are food for the caterpillars of certain Lepidoptera, such as the bagworm moth Taleporia tubulosa.
