Parmelia is the largest genus of leaf lichens with between 50 and 1322 species worldwide.
description
Parmelia is inherently inconsistent and attempts are being made to divide her into smaller genera. The separation of the genera Cetrelia , Hypogymnia , Menegazzia and Pseudevernia is generally accepted . The genera mentioned are difficult to distinguish from the layman. Confusion with other genera is also possible. The difficulty in describing the genus is characterized by the fact that in at least European identification keys (from e.g. Jahns) Parmelia remains after all other leaf lichens have been singled out due to special characteristics. In general, Parmelia has a darker underside with rhizines where the lichen is attached to the substrate. The top can be gray, yellow, or brown, often with organs of distribution. These can be apothecia , isidia or sorale . The medulla , which houses the algae partner of the lichen, is located between the top and bottom .
Occurrence
Parmelia species occur worldwide, from the Arctic to the Antarctic but with a focus on temperate climates. 125 species have been described from the Indian subcontinent.
