Pertusaria aptrootii is a species of crustose lichen in the family Pertusariaceae. It was described as a new species in 1998 by Alan W. Archer and John Alan Elix. The lichen occurs in Papua New Guinea, and is known from only two specimens collected at the type locality. The type was collected in Varirata National Park at an altitude of 800 m (2,600 ft), where it was found growing on conglomerate rock. It is named after Dutch lichenologist André Aptroot, who collected the type.
Marcelaria benguelensis is a tropical species of corticolous (bark-dwelling) and crustose lichen in the family Trypetheliaceae. It is found in continental southeast Asia.
Pertusaria epacrospora is a rare species of corticolous (bark-dwelling), areolate lichen in the family Pertusariaceae. Found in Australia, it was formally described as a new species in 1991 by lichenologist Alan W. Archer. The type specimen was collected in Park Beach at sea level; here, it was found growing on trees in a coastal sand dune. The lichen has a thin, pale yellowish-green thallus lacking soredia and isidia. It has numerous wart-shaped apothecia, the same colour as the thallus, which measure 0.4–0.8 mm in diameter and which have a single, inconspicuous ostiole. The ascospores, which number 2 per ascus, are smooth and fusiform (spindle-shaped), typically measuring 125–150 μm long by 35–45 μm wide. Pertusaria epacrospora is only known to occur at the type locality. Secondary compounds found in the lichen are thiophaninic acid and stictic acid as major components, and minor to trace amounts of constictic acid and hypostictic acid.
Carbacanthographis megalospora is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Brazil, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected by the first author from the Augusto Ruschi Biological Reserve at an altitude of 800 m (2,600 ft). The lichen has a whitish grey thallus with a thin cortex and an underlying black prothallus. Its asci contain a single ascospore. These spores are hyaline, and typically measure 235–255 by 30–40 μm. The specific epithet alludes to the large spores, the largest known in genus Carbacanthographis. C. megalospora contains stictic acid, cryptostictic acid, and constictic acid, which are lichen products that can be detected using thin-layer chromatography.
Mazaediothecium mohamedii is a species of corticolous (bark-dwelling) and crustose lichen in the family Pyrenulaceae. It is found in Peninsular Malaysia.
Astrothelium chulumanense is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in the Yungas montane forest of Bolivia, it was formally described as a new species in 2023. It is characterized by pseudostromata not differing in colour from the thallus, perithecia immersed for the most part in the thallus with the upper part elevated above and covered with orange pigment, apical and fused ostioles, the absence of lichexanthone, a clear hamathecium, eight-spored asci, and large, muriform ascospores with a thickened median septum.
Pertusaria galapagoensis is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Elix, Yánez-Ayabaca, A.W.Archer & Bungartz. The type specimen was collected on Floreana Island at an altitude of 371 m (1,217 ft), where it was found growing on the bark of a south-exposed trunk of Cedrella odorata. The species epithet refers to its distribution.
Pertusaria albineoides is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, A.W.Archer, Alba Yánez-Ayabaca, and John Elix. The type specimen was collected on Alcedo Volcano at an altitude of 1,089 m (3,573 ft), where it was found growing on a partially shaded, rain- and wind-exposed trunk of Scalesia microcephala. The species epithet refers to the similarity to the species Pertusaria albinea, from which it differs by having thin-walled ellipsoid-shaped ascospores that are longer and narrower.
Pertusaria cerroazulensis is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, Alan W. Archer, Alba Yánez-Ayabaca, and John Elix. The type specimen was collected from the Cerro Azul volcano at an altitude of 1,038 m (3,406 ft), where in a small, shaded woodland, it was growing on twigs of Psidium galapageium. The species epithet refers to the type locality.
Glyphis frischiana is a species of corticolous (bark-dwelling) script lichen in the family Graphidaceae. It is distinguished by its large ascospores, single-spored asci, and the presence of stictic acid as a major metabolite. Found on the trunk of Eucalyptus trees in Cameroon, it is similar in appearance to Glyphis atrofusca but can be distinguished by these key characteristics.
Aspiciliopsis is a genus of lichen-forming fungi in the family Trapeliaceae. It has two species, both of which occur in the Southern Hemisphere.
Malmidea allopapillosa is a species of corticolous (bark-dwelling), crustose lichen in the family Malmideaceae. It is found in Venezuela.
Malmidea volcaniana is a species of corticolous (bark-dwelling), crustose lichen in the family Malmideaceae. It is found in Venezuela. A major characteristic of the species is the coralloid (coral-shaped) clumps of isidia-like outgrowths on the thallus surface.
Astrothelium longisporum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. It occurs in the Atlantic Forest of Brazil.
Astrothelium curvatum is a species of corticolous lichen in the family Trypetheliaceae. Found in Brazil, it was described as a new species in 2016. It is characterised by its immersed pyriform ascomata with lateral ostioles and bent, muriform ascospores.
Enterographa aldabrensis is a species of corticolous (bark-dwelling), crustose lichen in the family Roccellaceae. It is only known to occur in Aldabra in the Seychelles.
Pseudopyrenula flavoreagens is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. It is found in Brazil and Panama, in both primary forest and disturbed rainforests.
Corticorygma is a monotypic fungal genus in the subfamily Graphidoideae of the family Graphidaceae. It contains a single species, the corticolous (bark-dwelling) crustose lichen Corticorygma stellatum. This script lichen is found in the shaded understory of rainforests in the Brazilian states of Rondônia and Paraná.
Pyrenula celaticarpa is a species of corticolous (bark-dwelling), crustose lichen in the family Pyrenulaceae. Found in Brazil, this species is notable for its deeply immersed ascomata with distinctive red ostioles (openings). The ascospores are 3-septate, meaning they are divided into four sections, and measure 21–24 μm by 10–11 μm.
Phlyctis subagelaea is a species of crustose lichen in the family Phlyctidaceae. It was described as new to science in 2006 from material collected in the tropical forests of southern India. Its species epithet, subagelaea, refers to its strong resemblance to the related species Phlyctis agelaea.
