Japewiella dollypartoniana is a species of crustose lichen in the family Lecanoraceae. It is widely distributed in the Appalachian Mountains of eastern North America, and has also been reported from Ontario, Canada. The lichen grows on tree branches and sapling and shrub stems at middle to high elevations.

Hypotrachyna oprah is a species of foliose lichen in the family Parmeliaceae. Found in the United States in North Carolina, Alabama, and Florida, it was described as new to science in 2019 by lichenologists James Lendemer and Jessica Allen. It was named in honor of Oprah Winfrey. It contains the secondary chemical lichexanthone.

Hypotrachyna mcmulliniana is a species of foliose lichen in the family Parmeliaceae. It has a blue-grey thallus about 3–10 cm (1–4 in) wide, with lobes 1.0–4.0 mm wide, and isidia without hairs. This species is most common in the southeast of North America but has been observed as far north as Connecticut. This lichen grows on conifers, hardwood trees and shrubs, and rocks. The conservation status of the lichen has not been ranked. This species was described in 2020 by James Lendemer and Jessica Allen, and was named to honor R. Troy McMullin, a lichen researcher and educator at the Canadian

Hypotrachyna kauffmaniana is a species of blue-gray to gray foliose lichen in the family Parmeliaceae. This species can only be located in eastern North America along the Appalachian Mountains, commonly found in Georgia, South Carolina, North Carolina, and Tennessee. The habitat of H. kauffmaniana is typically mid-elevation forests on both hardwood and conifer tree branches/trunks within the southern Appalachians. On rare occasions, this species can be found growing on non-calcareous rocks. H. kauffmaniana gathered its name in honor of Gary Kauffman, a botanist for the National Forest

Hypotrachyna appalachensis is a species of blue-gray to gray foliose lichen in the family Parmeliaceae. It can be found growing in eastern North America in the southern Appalachian Mountains. The species grows on the bark or wood of trees, specifically hardwood trees, either on the tree's trunk or base. Its name was chosen due to its distribution being entirely restricted to the Appalachian Mountains. The species was originally thought to be Hypotrachyna minarum, which it is morphologically identical to, until molecular data showed H. appalachensis consistently produced higher concentrations
