Melanohalea tahltan is a species of foliose lichen in the family Parmeliaceae. It was described as a new species in 2016. The species name honours the indigenous Tahltan people that live in northern regions of the Canadian province British Columbia. [1]

The type was found along the Cassiar Highway, south of Kinaskan Lake, where it was growing on the bark of Salix . It has also been found in Thompson Plateau in southern British Columbia. Melanohalea tahltan is morphologically similar to Melanohalea multispora , but is genetically distinct from that species. [1]

<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 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.

<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.

Melanohalea zopheroa is a species of lichen in the family Parmeliaceae. It was first formally described in 1977 by Ted Esslinger as Parmelia zopheroa. A year later, he transferred it to the new genus Melanelia, which he created to contain the brown Parmeliae species. In 2004, after early molecular phylogenetic evidence showed that Melanelia was not monophyletic, Melanohalea was circumscribed by lichenologists Oscar Blanco, Ana Crespo, Pradeep K. Divakar, Esslinger, David L. Hawksworth and H. Thorsten Lumbsch, and M. zopheroa was transferred to it. The lichen has a disjunct distribution, as it is found in South America (Chile) and in New Zealand.

Melanohalea ushuaiensis is a species of lichen in the family Parmeliaceae. It was first formally described in 1917 by Alexander Zahlbruckner as Parmelia ushuaiensis. Ted Esslinger transferred to the new genus Melanelia in 1978, which he circumscribed to contain the brown parmeliae species. In 2004, it was moved to the newly created genus Melanohalea. It is endemic to South America.

Melanohalea trabeculata is a species of foliose lichen in the family Parmeliaceae. It was first formally described by Finnish lichenologist Teuvo Ahti in 1966 as Parmelia trabeculata.

In 2004, it was moved to the newly circumscribed genus Melanohalea.

Melanohalea austroamericana is a species of foliose lichen in the family Parmeliaceae. It was described as a new species in 2016. The lichen is known only from two specimens collected in Chile's Laguna del Laja National Park, where they were discovered growing on bark in a forest of Chilean cedar. The specific epithet austroamericana refers to its South American distribution.

Melanohalea beringiana is a species of foliose lichen in the family Parmeliaceae. It was described as a new species in 2016. The type was collected near the Richardson Highway, north of Paxson, Alaska, where it was found growing on the bark of a trunk of balsam poplar. The specific epithet beringiana refers to its Alaskan distribution. It is morphologically similar to Melanohalea olivaceoides, but is genetically distinct from that species.

Melanohalea clairi is a species of lichen in the family Parmeliaceae. It was described as a new species in 2016. It is known from only two locations in the United States. The type specimen was collected from the White River National Forest in Colorado, in juniper-oak mountainous shrubland. Here it was found growing on Gambel oak. It has also been collected from the Wasatch Front in central Utah, where it was recorded on bigtooth maple. The lichen is morphologically similar to Melanohalea subolivacea, but is genetically distinct from that species.

Melanohalea columbiana is a species of foliose lichen in the family Parmeliaceae. It was described as a new species in 2016. The type was collected at the Rock Creek of the Channeled Scablands, where it was found growing on a species of hawthorne. The specific epithet columbiana refers to its occurrence in the Columbia River drainage basin and Columbian Plateau. The lichen has been recorded from Idaho, Washington, Central Oregon, and a single locale in the Peninsular Ranges in Southern California. It is morphologically similar to Melanohalea multispora, but is genetically distinct from that species.

Melanohalea mexicana is a species of lichen in the family Parmeliaceae. Found in Mexico, it was described as a new species in 2010 by Ted Esslinger and Rosa Emilia Pérez-Pérez. Within the genus Melanohalea, molecular phylogenetic analysis places it in the "subolivacea" group, which includes the species M. subolivacea and M. clairi.

Melanohalea nilgirica is a species of foliose lichen in the family Parmeliaceae. Found in India, it was described as a new species in 2005 by lichenologists Pradeep Divakar and Dalip Kumar Upreti. The type was collected from the Nilgiri Hills in Tamil Nadu, at an elevation of 2,000 m (6,600 ft). Its thallus is about 6 cm (2.4 in) in diameter, with a reddish-brown to dark brown upper surface. It is characterized by flat, dot-like pseudocyphellae that are flush with the lobe surface, white capitate soralia, and presence of caperatic acid. This is the only known occurrence of this compound in the genus Melanohalea.

Named for its resemblance to Melanohalea elegantula, it can be distinguished from that species by its slightly flattened, but not hollow, isidia.

<i>Melanohalea elegantula</i> Species of lichen in the family Parmeliaceae

Melanohalea elegantula, commonly known as the elegant camouflage lichen, is a species of lichen in the family Parmeliaceae. It was first described by Alexander Zahlbruckner in 1894 as Parmelia aspidota var. elegantula. Hungarian lichenologist Ödön Szatala promoted it to full species status, as Parmelia elegantula, in 1930. Ted Esslinger transferred it to the genus Melanelia in 1978. Finally, it was assigned to the newly circumscribed genus Melanohalea in 2004.

Parmelia imbricaria is a species of foliose lichen in the family Parmeliaceae. Found in western Canada, it was formally described as a new species in 2017 by Trevor Goward, Pradeep Kumar Divakar, María del Carmen Molina, and Ana Crespo. The type specimen was collected by Goward near the Clearwater River drainage, where it was found at an altitude of 700 m (2,300 ft) growing on a basalt boulder. The specific epithet refers to the "imbricate" lobes of the thallus. The lichen occurs in western Canada, with a range including southern Yukon and extending south to southern inland British Columbia. The European Parmelia pinatifida is a closely related species.
