Parmotrema afrocetratum is a species of saxicolous (rock-dwelling) foliose lichen in the family Parmeliaceae. [1] Described as new to science in 2005, it is found in Rwanda. [2]
Parmotrema is a genus of lichen belonging to the family Parmeliaceae. It is a large genus, containing an estimated 300 species, with a centre of diversity in subtropical regions of South America and the Pacific Islands.
Relicina is a genus of foliose lichens belonging to the large family Parmeliaceae. It contains 59 species.
Parmotrema asperum is a species of saxicolous lichen in the family Parmeliaceae. Found in Brazil, it was described as new to science in 2008. The milky-grey thallus of the lichen is up to 11 centimetres (4.3 in) in diameter, consisting of irregularly branched lobes measuring 2.0–6.5 mm wide. The lichen is named for the coarse appearance of the thallus.
Parmotrema applanatum is a species of saxicolous lichen in the family Parmeliaceae. Originally described from collections made in Vale do Sol, Brazil, it was introduced as new to science in 2002. In 2005, the lichen was recorded in China. The lichen has a grey thallus up to 6 cm (2.4 in) wide, comprising lobes that are 0.2–0.6 mm wide. It grows on tree-shaded rocks in open woods. The species is difficult to collect because the thallus adheres strongly to its substrate. The specific epithet appalantum refers to "the notoriously plane habit of the thalli". Parmotrema applanatum resembles P. hababianum, but differs from that species in lacking cilia, and containing traces of usnic acid and atranorin in its upper cortex.
Parmotrema alectoronicum is a species of saxicolous lichen in the family Parmeliaceae that was introduced as new to science in 2002. It was originally described from collections made in Serra do Caraça, Brazil, where it was found growing at an elevation of 1,220 m (4,000 ft). The lichen has a yellowish-green thallus up to 9 cm (3.5 in) wide, comprising lobes that are 2.0–4.0 mm wide. The margins of the lobes have cilia that are up to 1.5 mm long. The specific epithet alectoronicum refers to the presence of alectoronic acid in the medulla. This presence of this compound, as well as usnic acid in its cortex, is a rare combination in the genus Parmotrema.
Parmotrema alidactylatum is a species of saxicolous lichen in the family Parmeliaceae. Found in Argentina, it was described as new to science in 1998. The holotype was collected in Cerro Colorado in northern Córdoba Province, where it was found growing on granite. The thallus of the lichen is foliose, with a grey colour, and measures up to 10 cm (4 in) across. The specific epithet alidactylatum refers to the presence of aliphatic acids in the medulla and the dactylate upper surface. Parmotrema alidactylatum is similar in appearance and morphology to P. tsavoënse, but has different medullary chemistry.
Parmotrema soredioaliphaticum is a species of saxicolous lichen in the family Parmeliaceae. Found in South America, it was described as new to science in 1998. The holotype was collected in Cerro Colorado in northern Córdoba Province, Argentina, where it was found growing on a rock. The thallus of the lichen is foliose, with a pale grey colour, and measures up to 10 cm (4 in) across. It is a morph of the species Parmotrema alidactylatum with sorediate dactyls. Parmotrema soredioaliphaticum was reported from Bolivia in 2012.
Parmotrema barioense is a species of corticolous lichen in the family Parmeliaceae. The holotype specimen was collected in a Kerangas forest in Sarawak, Malaysia. It has a loosely attached greyish thallus measuring 10–12 cm (3.9–4.7 in) wide, comprising individual lobes 6–20 mm wide. It contains the secondary compounds atranorin, chloroatranorin, protocetraric acid, and butlerin derivatives. The lichen resembles Parmotrema zollingeri, but can be distinguished from that species by the older, convoluted lobes in the centre of the thallus, the larger ascospores, and the presence of butlerins.
Parmotrema abessinicum is a species of corticolous lichen in the family Parmeliaceae. It has been recorded from Africa, Asia, and Oceania.
Parmotrema austrocetratum is a species of lichen in the family Parmeliaceae. Found in Australia and New Zealand, it was described as new to science in 1988 by John Elix and Jen Johnston. The lichen, which can grow on either bark or rock, is light grey in colour, measures 6–12 cm (2.4–4.7 in) in diameter, and is loosely attached to its substrate. It is common on trees and rocks in coastal and hinterland areas along the subtropical and tropical east coast of Australia, as well as the North Island of New Zealand.
Parmotrema adspersum is a species of lichen in the family Parmeliaceae. It was originally described as a species of Parmelia by Edvard August Vainio in 1907. John Elix transferred it to Parmotrema in 2002, reasoning that its thick-walled ascospores are typical of that genus. Parmotrema adspersum is common in Thailand and the Philippines.
Parmotrema mellissii is a widely distributed species of corticolous lichen in the family Parmeliaceae. It was first described by Carroll William Dodge in 1959 as a species of Parmelia. Mason Hale transferred it to the genus Parmotrema in 1974. The type collection was made in Saint Helena. Parmotrema mellissii has a pale yellowish-buff coloured thallus at least 12 cm (5 in) in diameter, comprising rounded lobes about 15 mm wide and long. It has been found in the southern U.S.A., the Neotropics from Mexico to Colombia and Brazil, Africa, Asia, Australia and Oceania.
Parmotrema albinatum is a species of foliose lichen in the family Parmeliaceae that is found in Hawaii. It was originally described in 2001 as Rimelia albinata. Later phylogenetic analysis demonstrated that the genus Rimelia was synonymous with Parmotrema, so this species was transferred to that genus. The lichen is characterized by the sorediate and short-lacinulate thallus with salazinic acid in the medulla and traces of lobaric acid. The upper surface of the thallus is whitish, which probably a result of the thickness of the thick upper cortex.
Parmotrema anchietanum is a species of saxicolous lichen in the family Parmeliaceae. Found in South America, it was described as new to science in 2008. The holotype was collected on the rocky shore of Anchieta Island in São Paulo; the lichen is named after the type locality. Its leathery, pale grey thallus measures up to 16 cm (6.3 in) in diameter, composed of irregularly branched lobes that are typically 1–3 mm wide. Secondary compounds present in the lichen include atranorin and chloratranorin in the cortex, and salazinic acid and consalazinic acid in the medulla.
Parmotrema zicoi is a species of saxicolous lichen in the family Parmeliaceae. Found in Brazil, it was introduced as new to science in 2002.
Robert "Bob" Shaw Egan is a botanist and lichenologist, specializing in the family Parmeliaceae. He was the president of the American Bryological and Lichenological Society from 1999 to 2001.
Parmotrema gardneri is a species of foliose lichen in the family Parmeliaceae. It was first formally described in 1955 by Carroll William Dodge as Parmelia gardneri, from specimens collected in Brazil. Emmanuël Sérusiaux transferred it to the genus Parmotrema in 1984. In addition to South America, it is also found in Africa, Asia, and North America.
Xanthoparmelia nomosa is a species of saxicolous (rock-dwelling), foliose lichen in the family Parmeliaceae. It is found in Tasmania, Australia.
