Rinodina brauniana is a species of lichen in the family Physciaceae. It was described as new to science in 2019 and grows in North America in the Southern Appalachian Mountains in North Carolina, Tennessee and Alabama. It lives on the bark of deciduous trees, shrubs, and conifers. It was named in honor of Emma Lucy Braun.
Punctelia rudecta, commonly known as the rough speckled shield or the speckleback lichen, is a North American species of foliose lichen in the family Parmeliaceae. This species can be readily identified by the light color of the thallus underside, the relatively large lobes at the edges of the thallus, and the tiny white pores present on the top of the thallus that are characteristic of the genus Punctelia. The lichen is quite abundant and widespread in the eastern and southeastern United States, although it also occurs in Canada and northern Mexico, but is less common in these regions. The lichen usually grows on bark, and less commonly on shaded rocks. There are several lookalike Punctelia species; these can often be distinguished from P. rudecta by differences in distribution or in the nature of the reproductive structures present on the thallus.
Punctelia caseana is a species of foliose lichen in the family Parmeliaceae. Its range covers eastern North America, extending south to central and northern Mexico, where it grows on the bark of many species of hardwood and conifer trees.
Punctelia appalachensis, commonly known as the Appalachian speckled shield lichen, is a species of foliose lichen in the family Parmeliaceae. It is found in the eastern United States and eastern Canada. The lichen was first formally described in 1962 by lichenologist William Culberson as a species of Parmelia. He collected the type specimen growing on tree bark in West Virginia, Hildur Krog transferred it to the newly circumscribed genus Punctelia in 1982.
Punctelia reddenda is a widely distributed species of foliose lichen in the family Parmeliaceae. It occurs in Africa, Europe, North America, and South America, where it grows on bark and on rock.
Lecanora markjohnstonii is a species of crustose lichen in the family Lecanoraceae. Found in the southern Appalachian Mountain region of the United States, it was described as a new species in 2018 by Carly Anderson Stewart, Erin Tripp, and James Lendemer. The type specimen was collected from Little River Canyon National Preserve (Alabama), where it was found growing on sandstone on a steep slope at an elevation of 1,123 m (3,684 ft). The specific epithet honors Mark Johnston, an Episcopalian priest known for his contributions to environmental education and outreach in Alabama.
Japewiella dollypartoniana is a species of crustose lichen in the family Lecanoraceae. It is widely distributed in the Appalachian Mountains of eastern North America, and has also been reported from Ontario, Canada. The lichen grows on tree branches and sapling and shrub stems at middle to high elevations.
Leprocaulaceae is a family of mostly lichen-forming fungi. It is the single family in the monotypic order Leprocaulales. Leprocaulaceae contains three genera and about 33 species.
Cetrelia chicitae is a species of foliose lichen in the family Parmeliaceae. It is found in eastern Asia, North America, and Europe, where it grows on mossy rocks and tree trunks.
Lepraria harrisiana is a species of leprose lichen in the family Stereocaulaceae. It is widespread in the eastern United States where it occurs in humid habitats, such as conifer swamps and riparian forests.
Rockefellera is a fungal genus in the family Pannariaceae. It is a monotypic genus, containing the single species Rockefellera crossophylla. The genus was circumscribed by James Lendemer and Erin Tripp in 2017. The generic name honors the Rockefeller family, "for their century-long support of North American conservation efforts, particularly with respect to national parks."
Ochrolechia africana, commonly known as the frosty saucer lichen, is a species of crustose and corticolous (bark-dwelling) lichen in the family Ochrolechiaceae. It is a widely distributed species, found in tropical and subtropical areas of southern Africa, Asia, Australia, North America, and South America. The lichen is characterized by the presence of a white "frosty" or powdery apothecia.
Placidium arboreum, commonly known as the tree stipplescale, is a species of corticolous (bark-dwelling), squamulose (scaley) lichen in the family Verrucariaceae. It has a primarily North American distribution, with a range extending from eastern Canada south to Mexico, although it has also been reported from the West Indies and from Argentina.
Capronia harrisiana is a lichenicolous fungus on the tripartite foliose lichen Crocodia aurata. Although the host species is widespread in many areas of the world, no species of Capronia has previously been reported from Crocodia aurata, and Capronia harrisiana appears to be endemic to the southern Appalachian Mountains in southeastern North America. The new species is characterized by 50–120 µm wide ascomata, 40–95 µm long setae, (1–)3-septate, pale brown, 11.9–15.7 × 4.4–5.8 µm ascospores, and an I+ red hymenium.
Lecidea tessellata is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecideaceae. It was formally described as a species in 1819 by German botanist Heinrich Flörke. In northern North America, it is common and widely distributed, growing on non-calcareous rocks. It also occurs in Afghanistan, China, Nepal, Europe, and Russian Asia. In India, it has been recorded only from the alpine Western Himalayas at an altitude of 3,450 m (11,320 ft). Its southern distribution extends to James Ross Island, where it is locally common.
Pseudevernia consocians is a species of lichen in the family Parmeliaceae. It is found in both North America and Central America. Some characteristic features of Pseudevernia consocians are its well-developed, numerous isidia, relatively narrow lobes, and the presence of the lichen product lecanoric acid.
Leptogium acadiense is a species of corticolous (bark-dwelling), foliose lichen in the family Collemataceae. Found in northeastern North America, it was formally described as a new species in 2016 by James Hinds, Frances Anderson, and James Lendemer. The species epithet refers to the Acadian region of eastern North America, where the lichen seems to be most common.
Candelariella clarkiae is a rare species of crustose lichen in the family Candelariaceae. It was discovered in Colorado, USA, and formally described as a new species in 2015 by lichenologists Erin Tripp and James Lendemer. It was originally published with the species epithet clarki, but this was subsequently corrected to clarkiae. The name honors Dina Clark, Collections Manager at the University of Colorado herbarium, for her significant contributions to the knowledge of the Colorado flora, particularly the high plains ecosystems flanking the Southern Rocky Mountains. The authors note of the lichen that "it is bright and sunny, just like Dina’s disposition".
