Parmotrema adspersum is a species of lichen in the family Parmeliaceae. It was originally described as a species of Parmelia by Edvard August Vainio in 1907. John Elix transferred it to Parmotrema in 2002, reasoning that its thick-walled ascospores are typical of that genus. Parmotrema adspersum is common in Thailand and the Philippines.

Mason Hale transferred it to the genus Parmotrema in 1974. The type collection was made in Cuanza Sul Province (Angola), where it was found growing at an elevation of 1,000 m (3,300 ft); Dodge also noted the presence of the lichen in Cameroon and Uganda. Parmotrema amboimense has a pale olive-buff coloured thallus measuring up to 10 cm (4 in) in diameter.
Parmotrema mellissii is a widely distributed species of corticolous lichen in the family Parmeliaceae. It was first described by Carroll William Dodge in 1959 as a species of Parmelia. Mason Hale transferred it to the genus Parmotrema in 1974. The type collection was made in Saint Helena. Parmotrema mellissii has a pale yellowish-buff coloured thallus at least 12 cm (5 in) in diameter, comprising rounded lobes about 15 mm wide and long. It has been found in the southern U.S.A., the Neotropics from Mexico to Colombia and Brazil, Africa, Asia, Australia and Oceania.
Parmotrema araucariarum is a species of lichen in the family Parmeliaceae. It was first described scientifically as a species of Parmelia by Austrian botanist Alexander Zahlbruckner in 1909. Mason Hale transferred it to the genus Parmotrema in 1974. The lichen has been reported from Kenya, Tanzania, and South America.
Crespoa is a genus of five species of lichen in the family Parmeliaceae. Species in this genus are characterized by having an upper thallus surface that is wrinkled and reticulately ridged to coarsely foveolate.
Parmotrema zollingeri is a species of lichen in the family Parmeliaceae. It was originally described in 1860 as a species of Parmelia by German lichenologist Johann Adam Philipp Hepp, and named after Swiss botanist Heinrich Zollinger. Mason Hale transferred it to the genus Parmotrema in 1974.
Parmotrema andinum is a species of lichen in the family Parmeliaceae. It was first described as new to science in 1879 by Johannes Müller Argoviensis as a species of Parmelia. Mason Hale transferred it to Parmotrema in 1975. It is found in Africa, Asia, and South America. In Mauritania, this species is used as tobacco. A metabolomic analysis of this lichen revealed the presence of 30 secondary compounds.
Parmotrema appendiculatum is a species of lichen in the family Parmeliaceae. Found in South America, it was originally described by French botanist Antoine Laurent Apollinaire Fée in 1837 as a species of Parmelia. Mason Hale transferred it to the genus Parmotrema in 1974.
Parmotrema rampoddense, commonly known as the long-whiskered ruffle lichen, is a species of foliose lichen in the family Parmeliaceae. It is widely distributed in tropical regions and grows on the bark of oak and palm trees.

It was first formally described in 1955 by Carroll William Dodge as Parmelia gardneri, from specimens collected in Brazil. Emmanuël Sérusiaux transferred it to the genus Parmotrema in 1984. In addition to South America, it is also found in Africa, Asia, and North America.
Parmotrema hypoleucinum is a species of foliose lichen in the family Parmeliaceae. 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. The species was originally scientifically described by Austrian lichenologist Julius Steiner in 1918 as a member of genus Parmelia. Mason Hale transferred it to Parmotrema in 1974.
