Melanohalea ushuaiensis

Melanohalea ushuaiensis is a species of lichen in the family Parmeliaceae. It was first formally described in 1917 by Alexander Zahlbruckner as "Parmelia ushuaiensis". Ted Esslinger transferred to the new genus "Melanelia" in 1978, which he circumscribed to contain the brown parmeliae species. In 2004, it was moved to the newly created genus "Melanohalea". It is endemic to South America.
