Xanthoparmelia plittii is a foliose lichen in the genus Xanthoparmelia.
Xanthoparmelia plittii grows to around 4-10 cm in diameter with irregularly lobate lobes which are approximately 0.5-2 mm wide. The upper surface of the lichen is yellow-green, with cylindrical isidia. The lower surface is pale or medium brown in color with moderately to densely packed rhizines anchoring the lichen to the surface. [3] [4] Xanthoparmelia plittii is a member of the Xanthoparmelia mexicana group, a complex of similar species that differ mainly in their secondary chemistry. [5]
Xanthoparmelia plittii has been observed mostly in North America, [6] [7] but has been found in South America [8] and Europe as well. [9] [10]
Xanthoparmelia plittii has been found to contain usnic acid and stictic acid. [11] [5]
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.
Melanohalea is a genus of foliose lichens in the family Parmeliaceae. It contains 30 mostly Northern Hemisphere species that grow on bark or on wood. The genus is characterised by the presence of pseudocyphellae, usually on warts or on the tips of isidia, a non-pored epicortex and a medulla containing depsidones or lacking secondary metabolites. Melanohalea was circumscribed in 2004 as a segregate of the morphologically similar genus Melanelia, which was created in 1978 for certain brown Parmelia species. The methods used to estimate the evolutionary history of Melanohalea suggest that its diversification primarily occurred during the Miocene and Pliocene epochs.
Xanthoparmelia is a genus of foliose lichens in the family Parmeliaceae. This genus of lichen is commonly found in the United States, South America, southern Africa, Europe, Australia, and New Zealand.
Bryoria is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens. The genus has a widespread distribution, especially in boreal and cool temperate areas.
Xanthoparmelia mexicana, commonly known as the salted rock-shield, is a foliose lichen in the family Parmeliaceae. It grows in 4–10 cm diameter rosettes of gray-green to yellow-green lobes in arid climates all over the world.
Punctelia bolliana, the eastern speckled shield lichen, is a species of foliose lichen in the family Parmeliaceae. It is found in North America, with a distribution extending from the Canadian province of Ontario south to the central and northeastern United States and Mexico. It grows on the bark of both deciduous trees and coniferous trees. The combination of characteristics that distinguishes this species from others in genus Punctelia are the absence of the vegetative propagules isidia and soralia, a pale brown lower thallus surface, and the presence of the secondary chemical protolichesterinic acid in the medulla.
Allocetraria corrugata is a species of foliose lichen in the family Parmeliaceae. It is found in high-elevation locations in Yunnan, China, where it grows on rocks with mosses.
Parmelia fraudans is a species of foliose lichen in the family Parmeliaceae. It is found in Europe and North America, where it grows on rocks.
Xanthoparmelia salazinica is a species of lichen in the family Parmeliaceae. Found in South Africa, it was described as a new species in 1989 by American lichenologist Mason Hale. He classified it in Karoowia, a genus that has since been placed in synonymy with Xanthoparmelia following molecular phylogenetic analysis published in 2010.
Xanthoparmelia isidiovagans is a species of foliose lichen in the family Parmeliaceae
Xanthoparmelia subverrucigera is a species of saxicolous (rock-dwelling), foliose lichen in the family Parmeliaceae. Found in Spain and Zimbabwe, it was formally described as a new species in 2005 by lichenologists Oscar Blanco, Ana Crespo, and John Elix. The type specimen was collected by the authors in Embid de la Ribera at an altitude of 510 m (1,670 ft); here, the lichen was found growing on siliceous rocks. It has also been collected from Rhodes Matopos National Park in Zimbabwe. The specific epithet subverrucigera alludes to its resemblance with X. verrucigera.
Xanthoparmelia perezdepazii is a species of saxicolous (rock-dwelling), foliose lichen in the family Parmeliaceae. It is found in the Canary Islands.
Xanthoparmelia californica is a lichen which belongs to the Xanthoparmelia genus. The lichen is uncommon and is listed as imperiled by the Nature Conservatory.
Xanthoparmelia subramigera is a lichen which belongs to the Xanthoparmelia genus.
Xanthoparmelia angustiphylla is a foliose lichen that belongs to the genus Xanthoparmelia.
Xanthoparmelia ajoensis is a foliose lichen that belongs to the genus Xanthoparmelia. The lichen is uncommon and is listed as vulnerable by the Nature Conservatory.
Xanthoparmelia joranadia is a lichen which belongs to the Xanthoparmelia genus. The lichen is rare and is listed as imperiled by the Nature Conservatory. It is noted for being similar to Xanthoparmelia arida and Xanthoparmelia lecanorica.
Xanthoparmelia montanensis is a lichen which belongs to the Xanthoparmelia genus. It is also known as the Montana Rock-shield Lichen.
Xanthoparmelia wyomingica is a foliose lichen that belongs to the genus Xanthoparmelia.
Xanthoparmelia monadnockensis is a species of foliose lichen in the family Parmeliaceae, described by John Elix in 2003. It is native to Western Australia, particularly found in the Monadnocks Nature Reserve near Jarrahdale.
