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  [ es ] (Zaragoza Province) 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 . [1]

Xanthoparmelia subverrucigera contains several secondary compounds, including stictic acid and constictic acid as major metabolites, usnic acid, verrucigeric acid, lusitanic acid, and cryptostictic acid as minor metabolites, and trace amounts of connorstictic acid, and methylstictic acid. [1]

<i>Parmelia</i> (fungus) Genus of lichens

Parmelia is a genus of medium to large foliose lichens. It has a global distribution, extending from the Arctic to the Antarctic continent but concentrated in temperate regions. There are about 40 species in Parmelia. In recent decades, the once large genus Parmelia has been divided into a number of smaller genera according to thallus morphology and phylogenetic relatedness.

<span class="mw-page-title-main">Parmeliaceae</span> Family of lichens

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.

<i>Melanohalea</i> Genus of lichen

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 characterized 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 compounds. Melanohalea was circumscribed in 2004 as a segregate of the morphologically similar genus Melanelia.

<i>Melanelixia</i> Genus of fungi

Melanelixia is a genus of foliose lichens in the family Parmeliaceae. It contains 15 Northern Hemisphere species that grow on bark or on wood. The genus is characterized by a pored or fenestrate epicortex, and the production of lecanoric acid as the primary chemical constituent of the medulla. Melanelixia was circumscribed in 2004 as a segregate of the related genus Melanelia.

<i>Flavoparmelia</i> Genus of fungi

Flavoparmelia is a genus of foliose lichens in the family Parmeliaceae. Because of their appearance, they are commonly known as greenshield lichens. The widely distributed genus contains 32 species. It was circumscribed by American lichenologist Mason Hale in 1986 to contain 17 former Pseudoparmelia species with broad lobes, usnic acid in the cortex, and isolichenan in the cell walls.

<i>Punctelia</i> Genus of lichen

Punctelia is a genus of foliose lichens belonging to the large family Parmeliaceae. The genus, which contains about 50 species, was segregated from genus Parmelia in 1982. Characteristics that define Punctelia include the presence of hook-like to thread-like conidia, simple rhizines, and point-like pseudocyphellae. It is this last feature that is alluded to in the vernacular names speckled shield lichens or speckleback lichens.

<i>Xanthoparmelia</i> Genus of fungi

Xanthoparmelia is a genus of foliose lichen in the family Parmeliaceae. Xanthoparmelia is synonymous with Almbornia, Neofuscelia, Chondropsis, Namakwa, Paraparmelia, and Xanthomaculina. This genus of lichen is commonly found in the United States, as well as Australia, New Zealand and Ecuador.

<i>Xanthoparmelia loxodes</i> Species of lichen

Xanthoparmelia loxodes is a species of foliose lichen in the family Parmeliaceae. It was first formally described by Finnish botanist William Nylander in 1872, as Parmelia loxodes. In 1978, Ted Esslinger created the genus Neofuscelia, which contained species previously classified in Parmelia subgenus Neofusca; Neofuscelia loxodes was one of many species transferred here. In a 2004 molecular phylogenetic study published by Oscar Blanco, Ana Crespo, John A. Elix, David L. Hawksworth and H. Thorsten Lumbsch, they showed that Neofuscelia did not form a clade distinct from Xanthoparmelia, and they reduced it to synonymy under Xanthoparmelia.

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.

<i>Parmelina quercina</i> Species of lichen

Parmelina quercina is a species of foliose lichen in the large family Parmeliaceae. It is found in continental Europe.
