Candelariella boleana is a species of lichen in the family Candelariaceae, first described from Europe in 2009. It is distinguished from all other members of its genus by its distinctly spherical ascospores, which are contained in unusually large numbers (16–32) within each spore-bearing structure. The species forms small yellowish granules on the bark of deciduous and coniferous trees in montane forests across southern and central Europe, including Spain, Greece, Slovakia, Germany, and France. C. boleana has likely been overlooked for many years due to its small size and resemblance to the

Bacidina contecta is a species of lichen in the family Ramalinaceae, first found in inland rainforests of British Columbia. This small lichen forms olive-green crusts on the stems of shrubs like blueberry and forms tiny, pale fruiting bodies that are easily overlooked. It was discovered in 2009 and is known from scattered locations in southeastern British Columbia, Idaho, and Montana, where it grows in humid old-growth forests.

Scoliciosporum abietinum is a little-known species of crustose lichen in the family Scoliciosporaceae. This tiny lichen forms minute white to grey-white crusty patches only 0.3–0.6 mm across that grow directly on the living needles and leaves of conifer trees such as grand fir and western redcedar. It is found in the humid inland rainforests of southern British Columbia and northwestern Montana, where only four collections have been made, making it both rare and easily overlooked due to its extremely small size.

Myochroidea is a genus of lichen-forming fungi of uncertain familial placement in the order Lecanorales. It has four species of grey or brown-grey crustose lichens.

Lepraria torii is a species of corticolous and lignicolous (bark- and wood-dwelling), leprose lichen in the family Stereocaulaceae. It is found in northwestern North America.

Biatora ligni-mollis is a species of lichen in the family Ramalinaceae, first found in inland rainforests of British Columbia. This lichen grows exclusively on the soft, decaying wood of dead cedar and hemlock trees, forming thin white to pale cream crusts with abundant reddish-brown fruiting bodies. It gets its name from its preference for "soft wood" and glows brilliant white under ultraviolet light due to a lichen product called lobaric acid. Although first discovered in North American inland rainforests, it has since been discovered in several Western European countries including Belgium,

Biatora aureolepra is a species of lichen in the family Ramalinaceae, first found in inland rainforests of British Columbia. This lichen forms thin, powdery crusts that are bright yellow-green when fresh but fade to golden tones over time, and it has never been observed producing fruiting bodies. It grows on the bark and decaying wood of conifers in very humid, old-growth forests and has a scattered distribution in northwestern North America, central Norway, and Austria.

Absconditella amabilis is a rarely collected bark-dwelling lichen in the family Stictidaceae, first described in 2009 from the spray zone of a waterfall in the inland temperate rainforest of British Columbia. DNA-barcoded material from two humid montane forests in the Czech Republic has since shown that the species has a disjunct boreal–temperate range, persisting in permanently wet microsites on soaked conifer wood or living twigs. It produces minute, cream-coloured fruiting bodies that scarcely break the substrate surface and depends on constant moisture to survive.

Violella is a genus of two species of crustose lichens in the family Tephromelataceae. The genus is characterized by its brownish inner ascospore walls, brilliant violet hymenial pigment (called Fucatus-violet), and thallus chemistry. The type species, Violella fucata, was originally placed in genus Mycoblastus, but molecular phylogenetic analysis showed that this species as well as the Asian species V. wangii formed a phylogenetically distinct clade and warranted placement in a new genus. The generic name Violella, a diminutive form of the Latin viola, refers to the characteristic hymenium

Schaereria brunnea is a species of lichen in the family Schaereriaceae, first found in inland rainforests of British Columbia. This rare lichen forms very thin crusts made up of small pale brown patches, each topped with distinctive chocolate-brown barrel-shaped fruiting bodies that distinguish it from other tree-dwelling species in its genus. It was originally known from only three collections made between 1992 and 2007, all found growing on branches of western hemlock trees in ancient, misty forests over five centuries old. It has since been documented in Alaska.

Biatora epirotica is a species of corticolous (bark-dwelling) lichen in the family Ramalinaceae. Found in specific regions of the Balkans and Turkey, it was described as new to science in 2011 by lichenologists Christian Printzen and Toby Spribille.

Stereocaulon klondikense is a fruticose, rock-dwelling lichen discovered from Alaska. It is normally found in the alpine, especially on the tops of boulders used as bird perches with Gowardia nigricans and Sphaerophorus fragilis.

Pertusaria mccroryae is a species of white or greenish-white crustose lichen. It is found in northwestern North America (Alaska, British Columbia, Idaho, Oregon, and Montana), in forests with old trees. It grows from low elevation to 1,700 m (5,600 ft) on the bark of living trees (Picea sitchensis, Thuja plicata, and Tsuga heterophylla) or on logs, and is named in honor of Colleen McCrory, a Canadian environmental activist. The spore size and the chemistry distinguish it from other members of the genus.

Hypogymnia wilfiana is a species of foliose lichen in the family Parmeliaceae. It is found in western North America, where it grows on conifer trees.

Violella wangii is a widespread, but seldom-collected species of crustose lichen in the family Tephromelataceae. It is found in mountainous areas of Bhutan, China, India and the Russian Far East. The lichen forms small, pale grey crusty patches on tree bark and weathered wood, typically at high elevations where cool, misty conditions prevail. Despite its wide distribution across Asia's mountain ranges, it remained unknown to science until the 21st century due to its remote habitat and inconspicuous appearance.

Lobaria anomala, commonly known as the netted specklebelly, is a species of foliose lichen in the family Peltigeraceae. It is found in coastal western North America, where it grows on trees in humid environments. The lichen was first described as a new species in 1987 as a species of Pseudocyphellaria, though it had been mentioned in scientific papers before.

Llimoniella cinnabarinae is a species of lichenicolous (lichen-dwelling) fungus in the family Cordieritidaceae. It occurs in Alaska, where it grows on the thallus on the lichen Ramboldia cinnabarina.

Lempholemma corticola is a species of corticolous (bark-dwelling) crustose lichen in the family Lecanoraceae. It occurs in Greece.

Koerberiaceae is a small family of lichen-forming fungi in the order Peltigerales. It contains 3 genera and 9 species. The family was proposed by Toby Spribille and Lucia Muggia in 2012, after molecular phylogenetic analysis revealed the existence of three lineages of lichen-forming fungi in the suborder Peltigerineae of the order Peltigerales. The lineages represented the genera Steinera, Koerberia (the type genus of the family), and Vestergrenopsis. The latter genus was later folded into synonymy with Tingiopsidium. Steinera, circumscribed by Alexander Zahlbruckner in 1906, was previously

Elixia cretica is a rare species of corticolous (bark-dwelling), crustose lichen in the family Elixiaceae. It is only known to occur in a single location in the mountains of the Greek island of Crete.

Xylographa erratica is a species of lichen-forming fungus in the family Xylographaceae. It is a wood-inhabiting lichen that grows on conifer logs in boreal forests and on coastal driftwood, known from scattered localities across northern Europe, northeastern Asia, and western North America. The species was described in 2014 and is named for its irregularly oriented fruiting bodies, which point in different directions rather than following the wood grain.
