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.

The lichen is common in several Thai national parks in various parts of the country, occurring at elevations ranging from 200 to 1,600 m. In addition to Shorea, Pertusaria siamensis has also been recorded growing on Dipterocarpus, Ficus, and Vatica. The species epithet combines the old name for Thailand ("Siam") with the Latin suffix -ensis.

Graphis khaoyaiensis is a rare species of corticolous (bark-dwelling) script lichen in the family Graphidaceae. Found only in a specific region in Thailand, it closely resembles Graphis dichotoma but can be distinguished by its smaller ascospores and the absence of radiately branched lirellae.
Phlyctis communis is a species of corticolous (bark-dwelling) crustose lichen in the family Phlyctidaceae. Found in the Maharashtra state of India, it grows on the bark of tree trunks in semi-evergreen to dry deciduous forests. Described as a new species in 2012, the lichen is characterised by its greyish or greenish-white crustose thallus and numerous ascomata, ascospores that have between 7 and 14 transverse septa, and the presence of corstictic and salazinic acids.
Phlyctis sirindhorniae is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Phlyctidaceae. It shares some similarities with Phlyctis agelaea but can be distinguished by its smaller ascospores, larger apothecia, and a higher number of ascospores per ascus. It is only known to exist in a specific location in northeastern Thailand.
