The species epithet honours Australian lichenologist John Elix, who assisted the author in chemical analysis of lichen specimens. Pertusaria elixii is distinguished from related species by the number of ascospores in its ascus (four), and the presence of 2'-O-methyl-substituted homologues of perlatolic acid.
Pertusaria hypostictica is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found in Thailand, it was formally described as a new species in 2005 by Sureeporn Jariangprasert.

It has also been found in the peninsular region in the southern part of Thailand. The species epithet refers to the presence of hypostictic acid as a minor lichen product. It also contains stictic acid as a major substance, minor amounts of cryptostictic acid, peristictic acid, substictic acid, and trace amounts of constictic acid.
Pertusaria inthanonensis is a species of crustose lichen in the family Pertusariaceae. Found in northern and northeastern Thailand, it was formally described as a new species in 2005 by Sureeporn Jariangprasert. The type specimen was collected by the author from the Doi Inthanon National Park at an altitude of 1,900 m (6,200 ft), where it was found growing on the bark of a birch tree. The species epithet combines the name of the type locality with the Latin suffix ensis. The main distinguishing characteristics of the lichen are its asci that contain either two or four smooth ascospores, and the presence of confluentic acid, stictic acid, and lichexanthone. The latter substance causes the thallus to fluoresce a bright yellow colours when lit with a long-wavelength UV light.

It is only known to occur at this location. The species epithet combines the province of the type locality with the Latin -ensis. The main distinguishing characteristics of Pertusaria loeiensis are its asci, which contain only two spores, and the presence of the lichen products 2-O-methylperlatolic acid and stictic acid.
Pertusaria siamensis is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae.
