Umbilicaria hyperborea, commonly known as blistered rock tripe, [2] is a species of foliose lichen in the family Umbilicariaceae. It is widely distributed in arctic and alpine regions.
It was first described as a new species by Swedish lichenologist Erik Acharius in 1794 as Lichen hyperboreus. [3] Georg Franz Hoffmann transferred it to the genus Umbilicaria in 1796. [4]
In a 2017 molecular phylogenetic analysis of the genus Umbilicaria, U. hyperborea was proposed as the type species of the subgenus Umbilicaria. Closely related species include U. polyphylla , U. iberica , and U. arctica . [5]
The thallus of Umbilicaria hyperborea ranges in colour from medium- to dark-brown, with texture of the upper surface more or less smooth or warty. The thallus undersurface is smooth, and there are not any rhizines. The disc-shaped apothecia are flat to convex and have multiple complex ridges. [2]
The lichen typically grows on rock in arctic and alpine climates. [2] It has, however, been recorded growing on acidic wood; specimens found in this substrate may have an altered morphology compared to those found on rock, such as stunted and faded thalli lacking apothecia. [6] It is one of the most common Umbilicaria species in Arctic and adjacent Northern locations. [7] Umbilicaria hyperborea has a very slow growth rate; in a study undertaken in Greenland, it was measured as 0.3–0.4 mm per year over the time period 1933–1970. [8]
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.
Rock tripe is the common name for various lichens of the genus Umbilicaria that grow on rocks. They are widely distributed, including on bare rock in Antarctica, and throughout northern parts of North America such as New England and the Rocky Mountains. They are edible when properly prepared; soaking extensively and boiling with changes of water removes the bitterness and purgative properties. They have been used as a famine food in extreme cases when other food sources were unavailable, as by early American northern explorers.
Umbilicaria vellea is a species of lichen in the genus Umbilicaria. It is sometimes called navel lichen. It is found in North America and Europe in alpine and arctic habitats. It is similar to the species Umbilicaria americana, which has a more southern distribution.
Candelariella is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with Candelariella vitellina assigned as the type species.
Menegazzia terebrata is a species of foliose lichen found scattered across many continents, including North America, South America, Europe, Africa, and Asia.
Pilophorus acicularis, commonly known as the nail lichen or the devil's matchstick lichen, is a species of matchstick lichen in the family Cladoniaceae.
Physcia caesia, known colloquially as blue-gray rosette lichen and powder-back lichen, is a species of foliose lichenized fungus. First described by Georg Franz Hoffmann in 1784, it is common across much of Europe, North America and New Zealand, and more patchily distributed in South America, Asia, Australia and Antarctica. There are 2 subspecies: P. c. caesia and P. c. ventosa, as well as a number of distinct forms and varieties. Molecular studies suggest that the species as currently defined may be polyphyletic. It is typically pale gray shading to darker gray in the center, and grows in a small rosette, usually some 2–3 cm (0.79–1.18 in) across at maturity. It only rarely has apothecia, instead reproducing most often vegetatively via soredia, which are piled in round blue-gray mounds across the thallus's upper surface. It grows most often on rock—principally calcareous, but also basaltic and siliceous—and also occurs on bone, bark and soil. It is nitrophilic and is particularly common on substrates where birds perch.
Cladonia parasitica, commonly known as the fence-rail cladonia, fence-rail cup lichen or parasite club lichen, is a species of fruticose, cup lichen in the family Cladoniaceae. It was first described by Hoffmann in 1784 under the name Lichen parasiticus, until he reclassified it under the genus Cladonia in 1795.
Lecanora polytropa, commonly known as the granite-speck rim lichen, is a species of saxicolous lichen in the family Parmeliaceae. A small, inconspicuous species that grows in the cracks of rock surfaces, it has a cosmopolitan distribution and has been recorded on all continents, including Antarctica.
Protoparmelia badia is a species of crustose lichen in the family Parmeliaceae. It is a widely distributed, common species that grows on rocks.
Peltigera lepidophora, commonly known as the fan lichen, is a species of foliose lichen in the family Peltigeraceae. It was first described by Carl Linnaeus in his 1753 work Species Plantarum as Lichen venosus. German botanist Georg Franz Hoffmann transferred it to the genus Peltigera in 1789. P. venosa can be found in temperate and boreal regions of North America, Europe, and Asia, while occasionally being found in drier climates such as mountainous Arizona.
Solorina spongiosa, commonly known as the fringed chocolate chip lichen, is a species of lichen in the family Peltigeraceae. It was first formally described as a new species by the Swedish lichenologist Erik Acharius as Collema spongiosum. Italian botanist Martino Anzi transferred it to the genus Solorina in 1862.
Umbilicaria polyphylla, commonly known as petaled rock tripe, is a widely distributed species of saxicolous lichen in the family Umbilicariaceae. It was first described by Carl Linnaeus in his 1753 work Species Plantarum as Lichen polyphyllus. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus Umbilicaria in 1790. The lichen has a dark brown to black thallus that measures 2–6 cm (0.8–2.4 in) in diameter. The upper surface is smooth, while the lower surface is sooty black. It grows on exposed rocks, typically in arctic-alpine habitats.
Umbilicaria deusta, commonly known as peppered rock tripe, is a widely distributed species of saxicolous lichen in the family Umbilicariaceae. It was first described by Carl Linnaeus in his 1753 work Species Plantarum as Lichen polyphyllus. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus Umbilicaria in 1790. The lichen has a dark brown to nearly black thallus that typically measures 1–5 cm (0.4–2.0 in) in diameter. The upper surface is covered with tiny black dots that are granular isidia; the lower surface is the same colour as the upper surface, and is either smooth or covereds with dimples. It grows on exposed boulders and rocky outcrops.
Lecanora solaris is a species of crustose lichen in the family Lecanoraceae. Found in the Altai Mountains in Russia, the lichen was described as new to science in 2019 by Lydia Yakovchenko and Evgeny Davydov. The lichen is similar in general morphology to Lecanora somervellii, but can be distinguished from that species by its small, squamulose (scaly) to marginally lobate umbilicate thallus and the persistent margin of its apothecia. The species epithet makes reference to the bright yellow colour of the lichen.
Sporastatia is a genus of crustose lichens in the family Sporastatiaceae. It has four species. Sporastatia lichens are long-lived species that grow on siliceous or weakly calcareous rocks in arctic and alpine locales.
Umbilicaria virginis, commonly known as the blushing rock tripe, is a species of saxicolous (rock-dwelling) umbilicate lichen in the family Umbilicariaceae. It occurs in polar and alpine regions.
Umbilicaria maculata is a species of saxicolous (rock-dwelling) umbilicate lichen in the family Umbilicariaceae. It is found in high-altitude alpine locations in Poland and France.
Ochrolechia upsaliensis is a species of crustose lichen in the family Ochrolechiaceae. Found in the Northern Hemisphere, it is commonly known as the tundra saucer lichen.
Solorina crocea, commonly known as the orange chocolate chip lichen, is a species of terricolous (ground-dwelling) and foliose (leafy) lichen in the family Peltigeraceae. The lichen, which was first formally described by Carl Linnaeus in 1753, has an arctic–alpine and circumpolar distribution and occurs in Asia, Europe, North America, and New Zealand. It generally grows on the bare ground in sandy soils, often in moist soil near snow patches or seepage areas. Although several forms and varieties of the lichen have been proposed in its history, these are not considered to have any independent taxonomic significance.
