In recent years, the genus Parmelia has been divided into a number of smaller genera according to thallus morphology. Description and ecologyIn 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 perlata is called Dagad (north India), patthar ke phool (Hindi), kallu hoovu (Kannada), kallu pachi (Telugu), kal pasi (Tamil). It is used as a spice that provides a distinct, unmistakable flavor. Parmelia lichens are food for the caterpillars of certain Lepidoptera, such as the bagworm moth Taleporia tubulosa. Species
