Parmotrema robustum is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae.[2] It can be identified by its thin, leaf-like thallus, few (or sometimes no) tiny hair-like structures (cilia) on the edges, short lobes with powdery edges, and a black underside with few root-like structures (rhizines), along with a wide brown area without these structures. It produces specific secondary metabolites (lichen products), including protocetraric acid and atranorin, and sometimes usnic and fatty acids.[3]
The species was first scientifically described by the Swedish lichenologist Gunnar Degelius in 1941.[4] He classified it in the genus Parmelia. Mason Hale transferred it to the then newly circumscribed genus Parmotrema in 1974.[5]
Parmotrema robustum has a widespread distribution, with reports from Europe, eastern Australia, New Zealand, India, Thailand, Papua New Guinea, Macaronesia, and the Neotropics, including Bolivia, Brazil, Colombia, Costa Rica, Ecuador, and Venezuela.[3]
