Parmotrema hypoleucinum is a species of foliose lichen in the family Parmeliaceae.

[1] A study of Parmotrema hypoleucinum in Tunisia revealed that it contains atranorin and (+)-iso-usnic acid, chemical compounds of interest for their anti-inflammatory activity.

[3] The species was originally scientifically described by Austrian lichenologist Julius Steiner in 1918 as a member of genus Parmelia.

[4] Mason Hale transferred it to Parmotrema in 1974.
