Opegrapha reinkellae is a species of lichenicolous (lichen-dwelling) fungus in the family Opegraphaceae. Discovered on the Pacific coast of Peru, it was described as new to science in 2003 by Gerhard Follman. The holotype specimen was collected in Peru, possibly from the central region, by A. Winterfeld in the second half of the 19th century. The fungus grows specifically on the thallus of Roccella lirellina, a fruticose lichen. The species epithet reinkellae refers to the genus name Reinkella, which was erroneously applied to the host lichen when its ascomata were mistakenly thought to

Opegrapha perturbans is a species of lichenicolous (lichen-dwelling) fungus in the family Opegraphaceae. Discovered on the Pacific coast of Chile, it was described as new to science in 2003 by Gerhard Follman. The holotype was collected in Coquimbo, north Chile in 1838 by the French naturalist Claude Gay. The fungus grows specifically on the thallus of Ingaderia pulcherrima, a fruticose lichen. The species epithet perturbans (Latin for "confusing" or "misleading") refers to the long-standing mistaken identity of its ascomata (fruiting bodies) with the true fructifications of its host lichen.

Niebla limicola is a fruticose lichen that grows on barren mud flats and on sand among salt scrub along the Pacific Coast of the Vizcaíno Desert, of Baja California from San Vicente Canyon to Scammon’s Lagoon (Guerrero Negro). The epithet, limicola is in reference to the thallus growing on barren (alkali) soil.

Lecanographa imitans is a rare species of lichenicolous (lichen-dwelling) fungus in the family Lecanographaceae. Found on the Galápagos Islands, it was described as new to science in 2003 by Birgit Werner and Gerhard Follman. The holotype specimen was collected on Baltra Island, north of Santa Cruz Island, in January 1929. The fungus grows specifically on the thallus of Roccella gracilis, a fruticose lichen. The species epithet imitans (Latin for "imitating" or "mimicking") refers to the potential confusion of its ascomata (fruiting bodies) with the true fructifications of its host lichen.

Arthonia prominens is a species of lichenicolous (lichen-dwelling) fungus in the family Arthoniaceae. Discovered on the Pacific coast of Chile, it was described as new to science in 2003 by Gerhard Follman. The holotype was collected in the supralittoral zone between Las Ventanas and Quintero, in the Valparaíso Province of Central Chile, at an elevation of about 10 metres. The fungus grows specifically on the thallus of Ingaderia gracillima, a fruticose lichen. The species epithet prominens (Latin for "projecting" or "prominent") refers to the swollen macules (spots) produced on the host's

Arthonia ingaderiae is a species of lichenicolous (lichen-dwelling) fungus in the family Arthoniaceae. Discovered on the Pacific coast of South America, it was described as new to science in 2003 by Gerhard Follman. The holotype was collected from the Lomas of Paposo, north of Taltal, Chile, at an elevation of about 400 m (1,300 ft) in the lower fog belt. The fungus grows specifically on the thalli of two fruticose lichen species: Ingaderia gracillima and Ingaderia pulcherrima. The species epithet ingaderiae refers to the host genus Ingaderia. Arthonia ingaderiae is characterised by its

Arthonia darbishirei is a species of lichenicolous (lichen-dwelling) fungus in the family Arthoniaceae. Found on the Galápagos Islands, it was described as new to science in 2003 by Gerhard Follman and Birgit Werner. It was first collected on San Salvador Island in June 1872 during the Hassler Expedition. The fungus grows specifically on the thallus of Roccella nigerrima, a fruticose lichen that is endemic to the Galápagos. The species epithet darbishirei honours the British lichenologist Otto Vernon Darbishire (1870–1934), who initially described the host lichen and made significant
