Fuscopannaria siamensis is a species of lichen in the family Pannariaceae. [1] It is found in the mountainous forests of northern Thailand and in Tamil Nadu, India, where it grows in humid habitats in association with mosses.

Taxonomy

The lichen was formally described as a new species in 2000 by lichenologists Per Magnus Jørgensen and Pat Wolseley. The type specimen was collected by the authors from Doi Inthanon (Chiang Mai) at an altitude of 2,450 m (8,040 ft); there, on a roadside near the summit, the lichen was found growing amongst bryophytes that had fallen from the canopy. [2]

Description

The lichen has a squamulose to foliose thallus, brown to reddish-brown in colour, that forms patches up to 5 cm (2 in) in diameter. The marginal lobes are about 2 mm wide, and up to about 150  μm thick. Towards the tip, the lobes produce smaller lobules that break down somewhat to resemble soralia; this may be an adaptation to the wet growth conditions in its environment. Apothecia are rare in this species; if present, they are up to 1.5 mm in diameter and have a dark brown disc and a thalline margin with a squamulose form. The ascospores are colourless, lack septa, are more or less ellipsoid, and measure 18–20 by 9–10 mm. [2]

Habitat and distribution

Fuscopannaria siamensis is muscicolous (associating with mosses), and occurs in moist forests and the light-exposed edges of evergreen savannahs. It has been recorded at elevation ranges from 2,000 to 2,500 m (6,600 to 8,200 ft) in the mountains of northern Thailand. [2] The lichen was later reported from Tamil Nadu, India, at an elevation of 2,600 m (8,500 ft). In contrast to the original type material, the Indian material did not have lobes that eroded into soralia-like areas; the author suggested that perhaps this the "normal" form of the lichen, rather than the species "which therefore unfortunately appears to have been described on an extreme form". Jørgensen suggests the lichen may have a wider subtropical distribution. [3]

Vahliella was formerly placed in the family Pannariaceae until molecular phylogenetics showed that it did not belong there. Vahliella species are found in the Northern Hemisphere – mainly in North America, but also in Europe and India.

<i>Pyxine sorediata</i> Species of lichen in the family Caliciaceae

Pyxine sorediata, commonly known as mustard lichen, is a widely distributed species of foliose lichen in the family Caliciaceae. It has a subtropical to warm temperate distribution, and grows on bark, rocks, and moss as substrates. Pyxine sorediata has been reported from regions of North America, Europe, Africa, Asia, and Australasia.

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.

<i>Punctelia hypoleucites</i> Species of foliose lichen

Punctelia hypoleucites, commonly known as the southwestern speckled shield lichen, is a species of foliose (leafy) lichen in the family Parmeliaceae. First formally described by Finnish botanist William Nylander as a species of Parmelia, it was transferred to the genus Punctelia in 1982. The lichen is found in Africa, North America, and South America, where it grows on the bark of both hardwood and coniferous trees. Its greenish-grey thallus is covered with tiny white pseudocyphellae – minute holes in the thallus surface that facilitate gas exchange. Some macroscopic features that help distinguish this species from other related members of the genus include the presence and the structure of the apothecia, the absence of asexual surface propagules, and the light brown color of the thallus undersurface. Chemically, the presence of lecanoric acid in the medulla and atranorin in the cortex help distinguish it from lookalikes.

<i>Parmelia barrenoae</i> Species of lichen

Parmelia barrenoae is a species of foliose lichen in the large family Parmeliaceae. It was formally described as a new species in 2005. Before this, it was lumped together as one of several lichens in the Parmelia sulcata group—a species complex of genetically distinct lookalikes. Parmelia barrenoae is widely distributed, occurring in Europe, western North America, Africa, and Asia.

Steineropsis laceratula is a species of crustose placodioid lichen in the family Pannariaceae. It was first formally described in 1902 by French lichenologist Auguste-Marie Hue as Pannaria laceratula. Per Magnus Jørgensen proposed a transfer to Fuscopannaria in 1994. The taxon shuffled genera again in 2020 by Toby Spribille and Stefan Ekman after molecular phylogenetic analysis of the DNA from specimens collected in Alaska revealed its correct classification in the genus Steineropsis. The type specimen was collected in 1904 from Hakkoda, Japan, at an elevation of 1,200 m (3,900 ft); here the lichen was found growing on the bark of birch, but the species also grows on rock.

Psora taurensis is a species of terricolous (ground-dwelling), squamulose lichen in the family Lecanoraceae. It is found in the Taurus Mountains of Turkey.

Fuscopannaria obtegens is a species of corticolous (bark-dwelling), squamulose lichen in the family Pannariaceae. Found in China, it was formally described as a new species in 2007 by Norwegian lichenologist Per Magnus Jørgensen. The type specimen was collected from Nyingchi-Dongjuk at an elevation of 4,430 m (14,530 ft); there, on a south-facing slope, it was found growing on the stems of Juniper. It is only known to occur in the type locality. The widely spread thallus of the lichen is made of dichotomously branched, brown squamules up to 2 mm (0.08 in) in diameter. The squamules are imbricating, meaning they overlap each other; according to the author, they give the impression of a tiled roof reminiscent of stave churches in Norway.

Fuscopannaria albomaculata is a species of squamulose (scaley), corticolous (bark-dwelling) lichen in the family Pannariaceae. Found in China, it was formally described as a new species in 2004 by Norwegian lichenologist Per Magnus Jørgensen. The type specimen was collected from Hailuogou Glacier Forest Park at an elevation between 2,940 and 3,130 m. The lichen grows on deciduous trees, especially birch and willow, in mountainous forests near glaciers, at elevations between 3,000 and 4,000 m. It is distinguished from other members of genus Fuscopannaria by the white spots on its thallus.

Fuscopannaria hirsuta is a species of squamulose (scaley), corticolous (bark-dwelling) lichen in the family Pannariaceae. Found in China, it was formally described as a new species in 2004 by Norwegian lichenologist Per Magnus Jørgensen. The type specimen was collected from the Nyenchen Tanglha Mountains in Tibet at an elevation of 2,500 m (8,200 ft), where it was found growing on Salix bark. It has also been recorded growing on Juniperus bark. The species epithet hirsuta refers to the hairy upper thallus surface, the first in genus Fuscopannaria with this characteristic.

Fuscopannaria granulifera is a species of squamulose (scaley), corticolous (bark-dwelling) lichen in the family Pannariaceae. Found in India, it was formally described as a new species in 2004 by Norwegian lichenologist Per Magnus Jørgensen. The type specimen was collected from the Great Himalayan National Park at an elevation of 3,140 m (10,300 ft). It is only known to occur in the upper forests of western Himalayas. F. granulifera is the only corticolous member of its genus that has a green algal photobiont; all others have a cyanobacterial photobiont.

Fuscopannaria dispersa is a species of corticolous (bark-dwelling), squamulose lichen in the family Pannariaceae. It is found in China, where it grows on the bark of several tree species at an elevation range from 3,650 to 4,300 m, close to the forest limit. It was formally described as a new species in 2000 by Norwegian lichenologist Per Magnus Jørgensen. The type specimen was collected by Joseph Rock from the eastern slopes of Likang Snow Range in 1922, and has since been documented in a few locations in eastern China. The lichen has a brown thallus made of small squamules spread out over a distinct black prothallus. Its ascospores are ellipsoid, colourless, lack septa, and measure 15–17 by 9–10 μm. Fuscopannaria dispersa is similar to the more widespread F. leucosticta, but can be distinguished from that species by the squamulose form of its thallus and by its smaller, rounder ascospores.

Fuscopannaria dissecta is a species of corticolous (bark-dwelling), squamulose lichen in the family Pannariaceae. Found in Japan, it was formally described as a new species in 2000 by Norwegian lichenologist Per Magnus Jørgensen. The type specimen was collected by Syo Kurokawa from Mount Kōya at an altitude of 800 m (2,600 ft); there it was found growing on the rotting bark of trees. The lichen has a pale brown thallus that forms irregular patches comprising squamules that about are about 2 mm wide. The squamules are dissected–cut deeply into fine lobes–and it is this character that is referenced in the species epithet dissecta.

Fuscopannaria rugosa is a species of corticolous (bark-dwelling), lichen in the family Pannariaceae. It is found in Hubei and Guanxi in China, where it grows in mountainous forests. Fuscopannaria rugosa is identifiable by its foliose-squamulose thallus, which has longitudinal wrinkles on the upper surface. It also has a distinct hypothallus, a relatively thick algal layer, and a cortex made up of thick-walled cells in both the thalline and apothecial structures. It produces simple, hyaline ascospores that have a smooth, pointed tip at their apex.

Fuscopannaria saltuensis is a species of ground-dwelling, squamulose lichen in the family Pannariaceae. It is found in both the Eastern and Western Himalayas, where it grows on soil in open mountain forests with pastures and cliffs.

<i>Fuscopannaria leucosticta</i> Species of lichen

Fuscopannaria leucosticta, commonly known as the rimmed shingle lichen, is a species of lichen in the family Pannariaceae. It has a squamulose (scaley) thallus that lacks soredia and isidia, but has abundant apothecia with distinct white rims. Although its main centres of distribution are eastern North America and southeast Asia, where it grows in damp forests, it has been reported from various other high-altitude, humid locations.
