Ocellularia diospyri is a rare species of corticolous (bark-dwelling) lichen in the family Graphidaceae. It is found in northern Thailand.
The lichen was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected from Ton Krabak Yai National Park (Tak Province) at an elevation of about 500 m (1,600 ft); here, in a mixed forest, it was found growing on the trunk of a Diospyros tree. This genus is alluded to in the specific epithet diospyri. The lichen is only known to occur at the type locality. [1]
Ocellularia diospyri has a smooth, shiny, oliveaceous thallus with a thick cortex. The apothecia occur solitarily and are immersed in the medulla. They have a diameter of 0.6–0.65 mm, with a brown, fused exciple. The columella (the sterile central axis of the apothecia) is carbonized (blackened) and is visible from the small apothecial pore; it measures 0.08–0.2 mm in diameter. The ascospores are thin walled, spindle-shaped, and have from 12 to 23 locules (cavities); they typically measure 102.5–164.5 by 15.0–20.5 μm. This is unusually long for columellate species in the genus Ocellularia . O. diospyri contains the secondary compounds stictic acid and constictic acid. [1]

Ocellularia brunneospora is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected in the Namtok Phlio National Park ; here, in a moist evergreen forest at an elevation of 100 m (330 ft), the lichen was found growing on the bark of Anisoptera costata. Ocellularia brunneospora is only known to occur at the type locality.
Ocellularia flavescens is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in northern Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected from Doi Suthep National Park ; here it was found in an oak/chestnut forest at an elevation of 1,600 m (5,200 ft). It is only known from the type collection at the type locality. The lichen has shiny, smooth, whitish to mineral-grey thallus. It contains lichexanthone, a secondary compound that is uncommon in genus Ocellularia. The presence of this chemical causes the lichen thallus to fluoresce a golden-yellow colour when lit with a long-wavelength (365 nm) UV light. This feature is referenced in its specific epithet flavescens.
Ocellularia inthanonensis is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in northern Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected from a tree trunk in a cloud forest in Doi Inthanon National Park at an elevation of 2,450 m (8,040 ft). The specific epithet refers to the type locality. The lichen has a whitish mineral-grey thallus that is wrinkled and irregularly cracked.
Ocellularia kansriae is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Northern and Eastern Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected from Phu Hin Rong Kla National Park at an altitude of 1,475 m (4,839 ft); here, in an evergreen forest, it was found growing on the bark of Syzygium. The lichen has a shiny, olivaceous-grey thallus with a texture ranging from smooth to finely verruculose (warted). It contains protocetraric acid, a secondary compound. The specific epithet kansriae honours Thai lichenologist Kansri Boonpragob, a colleague who collected specimens from Khao Yai National Park in Eastern Thailand.
Ocellularia krathingensis is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins.

Found in southeastern Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected from Namtok Phlio National Park ; here, in a moist, lowland evergreen forest, it was found growing on Anisoptera costata. The lichen has a shiny, smooth, greenish thallus with a dense cortex and a white medulla with many crystals. Its ascospores are ellipsoid, thin walled, colourless, and typically measure 14.0–17.0 by 5.0–6.7 μm. It contains stictic acid, a secondary compound.
Ocellularia neoperforata is a rare species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Malaysia, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected by the second author from Gunung Mulu National Park (Sarawak) at an elevation of about 100 m (330 ft); here, it was found in a heath forest growing on a young tree. It is only known from the type collection at the type locality. The lichen has a shiny and smooth, greenish-grey thallus with a dense cortex and a white medulla. Its ascospores are trans-septate, narrowly ellipsoid, and measure 11–15 μm long. It contains fumarprotocetraric acid, a secondary compound. Ocellularia perforata is a lookalike species after which O. neoperforata is named. In contrast to the latter lichen, it has larger ascospores, less emergent apothecia, and contains protocetraric acid.
Ocellularia peremergens is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected from Doi Inthanon National Park at an elevation of 2,450 m (8,040 ft). The lichen has a shiny, pale greenish-grey thallus with a finely verruculose (warted) texture and a white medulla. The apothecia occur solitarily, measuring 0.7–1.2 mm in diameter; they are emergent, meaning they project somewhat above the thallus surface. O. peremergens contains fumarprotocetraric acid, a secondary compound.

Found in south-eastern Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected by the first author in Namtok Phlio National Park. The lichen has a somewhat shiny, smooth, olivaceous-buff thallus with a dense cortex and a white medulla. It produces colourless, thin-walled ascospores that measure 16.5–22.0 by 7.0–8.5 μm. The specific epithet rhicnoporoides alludes to its resemblance to Ocellularia rhicnopora.
