Viridothelium vonkonratii is a species of corticolous (bark-dwelling) crustose lichen-forming fungus in the family Trypetheliaceae. The lichen forms a very pale olive-yellow crust on tree bark with an uneven to bumpy surface featuring gall-like swellings. Its reproductive structures are solitary or become crowded, almost completely hidden within the lichen body with only the upper portions sometimes breaking through as dark greyish areas, and each produces large ascospores divided into numerous horizontal segments. The species is known only from Kadavu Island in Fiji, where it was discovered

Ocellularia thailandica is a species of corticolous (bark-dwelling), crustose lichen-forming fungus in the family Graphidaceae. It is a light yellowish green, bark-dwelling lichen with small, rounded fruiting bodies that are partly sunken in the thallus surface, known only from dry evergreen forest in northeastern Thailand. The species was described in 2016 on the basis of both morphological and molecular evidence, and is reported as closely related to Ocellularia albocincta.

Ocellularia rotundifumosa is a species of lichen-forming fungus in the family Graphidaceae. It is a greenish gray to olive, bark-dwelling lichen with rounded, sometimes urn-shaped fruiting bodies, known from dry evergreen forest in northeastern Thailand. The species was described in 2016 and is distinguished from the similar Ocellularia fumosa by its ascospores, which have rounded rather than pointed ends.

Ocellularia phatamensis is a species of corticolous (bark-dwelling) crustose lichen-forming fungus in the family Graphidaceae. It is a grayish, bark-dwelling lichen with small, rounded fruiting bodies partly sunken in the thallus surface, known from dry evergreen forest in northeastern Thailand. The species was described in 2016 and is named after the national park where it was first collected.

Ocellularia klinhomii is a species of corticolous (bark-dwelling), crustose lichen-forming fungus in the family Graphidaceae. It is a whitish gray, bark-dwelling lichen with small fruiting bodies set within raised, dark-ringed bumps on the thallus surface, known from dry evergreen forest in northeastern Thailand. The species was described in 2016 and is named in honour of the Thai mycologist Winia Klinhom.

Glaucotrema thailandicum is a species of lichen-forming fungus in the family Graphidaceae. It is a pale green to yellowish green, bark-dwelling lichen with conspicuous, urn-shaped fruiting bodies that are often partly merged, found in dry evergreen forest in Thailand. The species was described in 2016 and is distinguished within Glaucotrema by its ascospores, which are divided internally by both transverse and longitudinal cross-walls.

Astrothelium fijiense is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Fiji, it was formally described as a new species in 2016 by Robert Lücking, Khwanruan Naksuwankul, and Helge Thorsten Lumbsch. The type specimen was collected from Nakoba Levu (in the Suva area, Viti Levu island) at an altitude of 750 m (2,460 ft); there, it was found growing on bark on a steep slope in a secondary forest. The lichen has a smooth to uneven, light olive-yellow thallus that covers areas of up to 5 cm (2 in) in diameter. Both the thallus and the

Astrothelium aurantiacocinereum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. It occurs in New Caledonia.
