Parmotrema awasthii is a species of foliose lichen in the family Parmeliaceae. Found in India, it was described as new to science in 2003. [1]
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.
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.
Dalip Kumar Upreti is an Indian lichenologist. He served as Director and Chief Scientist at CSIR-National Botanical Research Institute, Lucknow during 1988 to 2017. Also he served as Head of Lichenology and herbarium division. Presently he is serving as CSIR-Emeritus Scientist in the same division.
Parmotrema is a species of saxicolous lichen in the family Parmeliaceae. Described as new to science in 2005, it is found in Rwanda.
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 aurantiacoparvum is a species of corticolous lichen in the family Parmeliaceae. Found in South America, it was described as new to science in 1992. Its thallus is pale grey or slightly brownish in colour, measuring 2–4 cm (0.8–1.6 in) wide. The lichen has been collected in Colombia, Guyana, French Guiana, Venezuela, and Brazil. It grows on canopy branches and on small trees in well-lit areas of forests or clearings.
Parmotrema abnuens is a species of corticolous lichen in the family Parmeliaceae. It was first introduced to science in 1885 as a species of Parmelia by William Nylander in 1885, who described the lichen from samples collected in Uruguay. Mason Hale transferred it to the genus Parmotrema in 1974. The species has also been recorded from Brazil and India.
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 aldabrense is a species of lichen in the family Parmeliaceae that is found in Africa. 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 the Aldabra Islands, where it was found growing on tamarind. It has also been recorded from Madagascar. The lichen has an olive-buff coloured thallus measuring up to 14 cm (5.5 in) in diameter.
Parmotrema amboimense is a species of lichen in the family Parmeliaceae that is found in Africa. 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 Cuanza Sul Province (Angola), where it was found growing at an elevation of 1,000 m (3,300 ft); Dodge also noted the presence of the lichen in Cameroon and Uganda. Parmotrema amboimense has a pale olive-buff coloured thallus measuring up to 10 cm (4 in) in diameter.
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.
Crespoa is a genus of five species of lichen in the family Parmeliaceae. Species in this genus are characterized by having an upper thallus surface that is wrinkled and reticulately ridged to coarsely foveolate.
Parmotrema andinum is a species of lichen in the family Parmeliaceae. It was first described as new to science in 1879 by Johannes Müller Argoviensis as a species of Parmelia. Mason Hale transferred it to Parmotrema in 1975. It is found in Africa, Asia, and South America. In Mauritania, this species is used as tobacco. A metabolomic analysis of this lichen revealed the presence of 30 secondary compounds.
Parmotrema appendiculatum is a species of lichen in the family Parmeliaceae. Found in South America, it was originally described by French botanist Antoine Laurent Apollinaire Fée in 1837 as a species of Parmelia. Mason Hale transferred it to the genus Parmotrema in 1974.
Parmotrema zicoi is a species of saxicolous lichen in the family Parmeliaceae. Found in Brazil, it was introduced as new to science in 2002.
