Peltigera is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. [2] Commonly known as the dog or pelt lichens, species of Peltigera are often terricolous (growing on soil), but can also occur on moss, trees, rocks, and many other substrates in many parts of the world. [3]

Contents

Most species of Peltigera have the cyanobacterium Nostoc as the dominant photobiont but some have the algae Coccomyxa. The presence of both a green alga and a cyanobacterium makes some tripartite; in this case they show cephalodium growths containing the third partner, Nostoc. Because of their ability to fix nitrogen from the atmosphere, such lichens are influential in soil composition and generation.

Description

Species of Peltigera are foliose, with broad lobed thalli. Although the size of the thalli is variable and species-dependent, in some species the thalli can grow quite large, up to 30 cm in diameter. [4] The color of the upper surface may range from drab gray, brown or greenish. Lower surfaces are typically without a cortex (unlike other foliose lichens), [5] and cottony, often with fungal hyphae fused to form a network of veins. The reproductive structures isidia, soredia or lobules may be present in some species. [6] All species of Peltigera associate with the nitrogen-fixing cyanobacteria Nostoc . [7] [8]

Peltigera can be distinguished from the equally large and leaf-like lichen, Nephroma , by its veined lower cortex; Nephroma, by contrast, has a smooth, unveiled lower cortex. [9]

Habitat

Peltigera are mainly ground-dwelling, but can also be found on mosses or dead wood. [9] Some species are used as forest succession indicators.

Taxonomy

In 1753, Linnaeus first described the species Lichen apthosus and L. caninus back when all known lichens were grouped into the genus Lichen. [10] Later, in 1787, Willdenow circumscribed the genus Peltigera, and redescribed P. aphthosa and P. canina . [11]

The generic name is derived from the Latin language pelta (small shield), and refers to the shield-shaped thallus in these species. The common name, the dog lichen, refers to the perceived resemblance of P. caninus to a dog. [12]

Phylogeny

In a comparative analysis of both morphological and chemical characteristics as well as sequences of large subunit nuclear ribosomal DNA, it was shown that the genus Peltigera is monophyletic. [13] Several species, such as P. canina , have been changed to a group as there appears to be several species clustered under a single name.

Distribution

The Peltigera have a widespread distribution, and are found on all continents. There are 34 North American species, 30 European species, 25 species from South America, and 16 species from New Zealand. [3] [4] [14] [15]

Uses

Peltigera species have been used historically to treat wounds, urinary disorders, thrush, tuberculosis, and rabies. [12] [17] [18] P. apthosa was used as a remedy for cough [19] and infantile aphthae. [20] P. furfuracea has shown potent antioxidant activity and reducing power. [21] Similarly, Peltigera specimens from Hawaii and Iceland have also been reported to show pronounced antioxidant activity. [22]

Food source

Although a few reports have described caribou and reindeer feeding on the thalli of Peltigera, [23] in general, species of Peltigera are not commonly used as a food source by mammals. [24] [25] A study of the grazing habits of the land snails Cantareus aspersa and Limax species revealed that these snails prefer to eat Peltigera species (such as P. praetextata ) that are lacking in secondary metabolites. [26]

Bioactive compounds

Peltigera leucophlebia contains the compounds tenuiorin and methyl orsellinate, which are inhibitory to the enzyme 15-lipoxygenase. [27] Tenuiorin is also known to occur in P. apthosa , P. malacea and P. neckeri . [28] A mixture of methyl and ethyl orsellinates have been identified from P. aphthosa that had antibacterial activity against Gram-positive and -negative bacteria. [29] The novel non-protein amino acids solorinine and peltigerine have been detected in various species of Peltigera. [30]

Peltigerales is an order of lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota.

It contains two suborders, eight families and about 45 genera such as Lobaria and Peltigera.

<span class="mw-page-title-main">Peltigeraceae</span> Family of lichenized fungi in the order Peltigerales

The Peltigeraceae are a family of lichens in the order Peltigerales. The Peltigeraceae, which contains 15 genera and about 600 species, has recently (2018) been emended to include the families Lobariaceae and Nephromataceae. Many Peltigeraceae species have large and conspicuous, leathery thalli. They largely occur in cool-temperate to tropical montane climates. Tripartite thalli involving fungus, green algae and cyanobacteria are common in this family.

<i>Sticta</i> Genus of lichens

Sticta is a genus of lichens in the family Peltigeraceae. The genus has a widespread distribution, especially in tropical areas, and includes about 114 species. These lichens have a leafy appearance, and are colored brown or black. Sticta species with cyanobacteria as photobionts can fix nitrogen from the atmosphere, and due to their relative abundance and high turnover, they contribute appreciably to the rainforest ecosystem. They are commonly called spotted felt lichens.

<i>Peltigera canina</i> Species of lichen in the family Peltigeraceae

Peltigera canina, commonly known as the dog lichen, is a widely distributed species of foliose lichen in the family Peltigeraceae. It was originally described by Carl Linnaeus in his 1753 work Species Plantarum. German botanist Carl Ludwig Willdenow transferred it to the genus Peltigera in 1787. This species is currently undergoing research as it is likely multiple species under one united name.

Peltigera serusiauxii is a species of foliose lichen in the family Peltigeraceae. It is found in Papua New Guinea and Sabah, northern Borneo (Malaysia). It was described as a new species in 2020 by Nicolas Magain, Jolanta Miadlikowska, Bernard Goffinet, and Antoine Simon. The type was collected in Mount Gahavisuka Provincial Park, where it was found growing in a mostly undisturbed mossy mountain forest dominated by chinquapin trees. The specific epithet honours Belgian lichenologist Emmanuël Sérusiaux, "who substantially contributed to our understanding of the world-wide diversity of Peltigera, especially in Papua New Guinea where he collected the type material among several other specimens of this new species".

Peltigera papuana is a lichenized fungus in the family Peltigeraceae. It was described in 2009 from Madang Province of Papua New Guinea, from which it obtained its specific epithet. Genetic analysis of both the mycobiont and the photobiont, which is a Nostoc cyanobacterium, suggests that the evolutionary origin of Pelitgera papuana is from an ancient dispersal event from South America, although this remains inconclusive.

It is similar to the Peltigera polydactylon, but with distinct genetic, geographic, and chemical characteristics. P. seneca is characterized by its small thalli with narrow lobes and a pale zone on margins of its lower thallus surface.

<i>Peltigera hydrophila</i> Species of lichen

Peltigera hydrophila is a species of foliose lichen in the family Peltigeraceae. First described in 2020, it distinguishes itself through a distinct, hairless thallus that turns deep blue-violet when it becomes wet. Found primarily in the Magallanes Region of Chile, this small leafy lichen clings closely to mosses and other substrates. Distinctive features include the always-present reddish-brown to dark brown apothecia and the Peltigera-type ascospores that contain three internal partitions, or septa. Despite sharing a habitat with similar species like P. aubertii and P. frigida, P. hydrophila sets itself apart through its unique thallus surface texture and colour. This semi-aquatic lichen primarily thrives in humid forests, shrubby and herbaceous vegetation in southern Chile, particularly near waterfalls, streams, and other wet environments.
