It was formally described as a new species in 2016 by lichenologists Christian Printzen and John McCarthy. The type specimen was collected along the Route de mon grand-père Trail in Port au Port Peninsula, where it was found growing on moss at base of a stem of balsam fir. The species contains argopsin, and norargopsin as major and minor lichen products, respectively.
Coenogonium lueckingii is a species of corticolous (bark-dwelling), crustose lichen in the family Coenogoniaceae. It is known to occur in a couple of locations in South Korea, where it grows on the bark of trees in humid locations.
Biatora pontica is a species of corticolous (bark-dwelling), leprose lichen in the family Ramalinaceae. It is a widely distributed species, having been recorded in Africa, Asia, Europe, and North America.
Placomaronea minima is a species of saxicolous (rock-dwelling) crustose lichen in the family Candelariaceae. Found in South America and Southern Africa, it was formally described as a new species in 2009 by lichenologists Martin Westberg and Patrik Frödén. The type specimen was collected by the second author from the Santiago Metropolitan Region (Chile) at an altitude of about 1,200 m (3,900 ft), where it was found growing on rocks on a hill outside of San José de Maipo. The species epithet minima refers to its small size.
Coenogonium flammeum is a species of corticolous (bark-dwelling), crustose lichen in the family Harpidiaceae. It is found in Argentina.
Biatora toensbergii is a species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae. It is found in Norway and northwestern North America.
Biatora bacidioides is a species of corticolous (bark-dwelling), leprose lichen in the family Ramalinaceae. It was formally described as a new species in 2003 by the lichenologists Christian Printzen and Tor Tønsberg, from specimens collected from Picea orientalis forests of north-eastern Turkey. It was recorded from Ukraine in 2018.
Biatora chrysanthoides is a species of corticolous (bark-dwelling), leprose lichen in the family Ramalinaceae. It is found in Norway, the Pacific Northwest of northern North America, Sweden, and Russia. It was formally described as a new species in 2003 by the lichenologists Christian Printzen and Tor Tønsberg. It contains gyrophoric acid in both the thallus and the apothecia, resulting in a C+ chemical spot test reaction. Its ascospores are 9.3–10.7 by 3.2–3.3 μm.
Biatora pausiaca is a species of corticolous (bark-dwelling), leprose lichen in the family Ramalinaceae. Found in the United States, it was formally described as a new species in 2003 by the lichenologists Christian Printzen and Tor Tønsberg. Its ascospores are 3.5–6.5 μm wide, and it does not contain any lichen products detectable with thin-layer chromatography. It is closely related to Biatora vezdana; these two species form a clade that itself has a sister relationship with Biatora radicicola.
Hafellia alisioae is a rare species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. Found in the Canary Islands, it was formally described as a new species in 2003 by Javier Etayo and Bernhard Marbach. The species epithet alisioae is derived from alisios, the Spanish word for the moisture-laden Atlantic winds that blow from the northeast, bringing high humidity and rain to exposed coasts with biodiverse lichen growth. Mireia Giralt and Pieter P.G. van den Boom proposed to transfer the taxon to the genus Buellia in 2011.
Ramboldia gowardiana is a species of corticolous (bark-dwelling), crustose lichen in the family Ramboldiaceae. First discovered in 2003 in Montana, United States, it typically appears as a grayish or greenish crust on tree bark, particularly on conifers like pines and firs. The lichen is characterised by its small, bright red to orange-red reproductive structures (apothecia) visible on its surface. R. gowardiana is found in dry, temperate forests from Alaska to California, often at elevations between 300 and 1,400 meters. Initially classified in a different genus, it was reclassified as Ramboldia in 2008 based on genetic studies. This lichen is part of the biodiversity of the Pacific Northwest region of North America.
Dictyocatenulata is a fungal genus of uncertain classification in the subclass Ostropomycetidae. It contains the single species Dictyocatenulata alba. Originally described in 1967 as a bark-dwelling fungus, it was later recognised as a lichen in 2004. The genus is characterised by its unique reproductive structures called synnemata, which are upright, stem-like formations that produce spores. D. alba has a widespread distribution, found in North and Central America, Asia, and Europe, typically growing on tree bark in humid forests. Recent molecular studies suggest that Dictyocatenulata may be closely related to the genus Thelenella, potentially representing an asexual stage of unknown Thelenella species. This lichen is distinguished by its thin, greenish thallus (body) and its spores, which are divided into many cells and arranged in chains, features that give the genus its name.
Lecidea coriacea is a species leprose lichen in the family Lecideaceae. Found in Europe and North America, where it grows on the bark and wood of various trees in old-growth and montane forests, it was scientifically described in 2016.
Bryobilimbia australis is a species of crustose lichen in the family Ramalinaceae. First described by lichenologist Gintaras Kantvilas in 2005 from specimens collected in Tasmania, this lichen forms dull-coloured, uneven patches that range from pale greyish to brownish or greenish grey. It is distinguished by its large, black, berry-like reproductive structures that can form complex clusters up to 9 millimetres wide, and its broad ecological tolerance. The species is found across the Southern Hemisphere, occurring in Tasmania, south-eastern mainland Australia, New Zealand, and Tierra del Fuego, where it grows on soil, plant litter, mosses, and dead vegetation in habitats ranging from coastal heathlands to alpine zones.
