Oxneria ussuriensis is a species of corticolous, crustose lichen in the family Teloschistaceae. It is found in a single location in the Russian Far East.
The lichen was formally described as a new species in 2014 by lichenologists Sergey Kondratyuk, Soon-Ok Oh, and Jae-Seoun Hur. The type specimen was collected by the first author from a park in Kraskino (in the Khasansky District of Primorsky Krai), where he found it growing on a Populus tree. The species epithet refers to the type locality. [1]
Oxneria ussuriensis has a deep orange to orange-yellow rosette-like thallus that has a diameter of 4–8 mm (0.16–0.31 in). The individual lobes comprising the thallus are 1.5–2 mm long, and have a width that ranges from 0.3 to 0.7 mm in the narrowest parts to 1 mm in the widest parts. The terminal parts of the lobes sometimes branch out to form secondary lobes or lobules. The underside of the lobes are covered with bluish-greyish soredia. Individual soredia are irregularly elongated and have a diameter from 20 to 50 μm; sometimes soredia aggregate into larger structures (consoredia) that are irregularly rounded with a diameter of 60–70 μm. [1]
The apothecia made by Oxneria ussuriensis are lecanorine in form with a diameter of 0.6–1.7 mm and a bright orange disc that is either flat or somewhat concave. Ascospores have a narrow ellipsoidal shape and dimensions of 9–23 by 5.5–10 μm. [1]
Xanthomendoza huculica , found in Ukraine, is somewhat similar in appearance and morphology to Oxneria ussuriensis, but X. huculica has a larger thallus (up to 3 cm wide) made of larger lobes (2.5–7 mm long and 0.3–0.7 mm wide), and its spores have a smaller length range (10–17 μm) and are thinner (5–7 μm). [1]
Oxneria ussuriensis grows on the bark of roadside or parkland trees. It is only known from the type collection in the Russian Far East. Associated lichen species include Caloplaca ussuriensis , Candelaria concolor , Hyperphyscia adglutinosa , Phaeophyscia adiastola , Physconia detersa , and species from the genera Arthothelium , Lecanora , Phaeophyscia , Melaspilea , and Rinodina .

Neobrownliella brownlieae is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed in Australia.
Lecanora muralis(Protoparmeliopsis muralis) is a waxy looking, pale yellowish green crustose lichen that usually grows in rosettes radiating from a center (placodioid) filled with disc-like yellowish-tan fruiting bodies (apothecia). It grows all over the world. It is extremely variable in its characteristics as a single taxon, and may represent a complex of species. The fruiting body parts have rims of tissue similar to that of the main nonfruiting body (thallus), which is called being lecanorine. It is paler and greener than L. mellea, and more yellow than L. sierrae. In California, it may be the most common member of the Lecanora genus found growing on rocks (saxicolous).
Hypogymnia congesta is a rare species of foliose lichen in the family Parmeliaceae. Found in China, it was formally described as a new species in 2003. The lichen grows on the bark and wood of conifers and bamboo. Hypogymnia congesta has a brown to brownish-grey foliose thallus measuring up to 8 cm (3.1 in) long or broad, with a cartilage-like texture. The lichen is chemically distinct, containing physodic acid and virensic acid; the latter substance is otherwise unknown from genus Hypogymnia.
Punctelia purpurascens is a species of foliose lichen in the family Parmeliaceae. Found in Brazil, it was formally described as a new species in 2007 by lichenologists Marcelo Marcelli and Luciana da Silva Canêz. The type specimen was collected in the municipality of Vicara in the southern Brazilian state of Rio Grande do Sul. There it was found growing on a basaltic rock in an open field. The specific epithet purpurascens refers to the unusual K+ purple reaction of the medulla.
Punctelia jujensis is a species of foliose lichen in the family Parmeliaceae. It is found in Argentina and Brazil.
Lecanora panticapaensis is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecanoraceae. It occurs in a single locality in Dnipropetrovsk Oblast, Ukraine, where it grows on the vertical surfaces of black schist beside a river.
Caloplaca kedrovopadensis is a little-known species of crustose lichen in the family Teloschistaceae. It is only found in the Kedrovaya Pad Nature Reserve in the Russian Far East, and on the Jiri Mountain of South Korea. The lichen has been recorded growing on rocks and on bark.
Lecanora ussuriensis is a species of saxicolous (rock-dwelling) lichen in the family Lecanoraceae. It is found in single localities in the Primorsky Krai region of the Russian Far East, as well as in Japan.
Opegrapha verseghyklarae is a little-known species of lichenicolous (lichen-eating) fungus in the family Teloschistaceae. It is found in the Russian Far East, where it grows on the thalli and apothecia of the crustose lichen Ochrolechia pallescens.

Characteristics of the lichen include its small thallus, the disposition of the rhizines on the thallus undersurface, and the lack of vegetative propagules.

Imshaugia pyxiniformis is a rare species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. It is only known to occur at its type locality in the North Region of Brazil. Characteristics of the lichen include its narrow, incised lobes, lack of vegetative propagules, its pale lower cortex, and presence of the substance lichexanthone.
Opeltiella is a genus of lichen-forming fungi in the family Candelariaceae. The genus, established by Sergey Kondratyuk in 2020, has four species. It is differentiated from the similar genus Candelaria by its unique features such as eight-spored asci and absence of a lower cortical layer and true rhizines. The genus is characterised by its areolate to more or less squamulose or foliose thallus and the unique chemical substances it contains, such as calycin, pulvinic and vulpinic acids, and pulvinic acid lactone.
