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.
Punctelia hypoleucites, commonly known as the southwestern speckled shield lichen, is a species of foliose (leafy) lichen in the family Parmeliaceae. First formally described by Finnish botanist William Nylander as a species of Parmelia, it was transferred to the genus Punctelia in 1982. The lichen is found in Africa, North America, and South America, where it grows on the bark of both hardwood and coniferous trees. Its greenish-grey thallus is covered with tiny white pseudocyphellae – minute holes in the thallus surface that facilitate gas exchange. Some macroscopic features that help distinguish this species from other related members of the genus include the presence and the structure of the apothecia, the absence of asexual surface propagules, and the light brown color of the thallus undersurface. Chemically, the presence of lecanoric acid in the medulla and atranorin in the cortex help distinguish it from lookalikes.
Bryobilimbia is a genus of lichen-forming fungi belonging to the family Lecideaceae. It was circumscribed in 2014 by Alan Fryday, Christian Printzen, and Stefan Ekman. The type species is Bryolimbia hypnorum.
Lepraria incana is a species of dust lichen in the family Stereocaulaceae. First described scientifically by Johann Jacob Dillenius in 1741, and then formally by Carl Linnaeus in 1753, it is the type species of the genus Lepraria. The thallus of this species is green to greyish-green, and powdery – as if made of tiny granules. These granules are soredia, which are asexual reproductive structures. Like most members of genus Lepraria, the lichen has few distinguishing features, lacking both a medulla and sexual reproductive structures (apothecia). Chemically, the lichen is characterised by the presence of the secondary chemicals known as divaricatic acid and zeorin.
Malmidea attenboroughii is a species of corticolous (bark-dwelling), crustose lichen in the family Malmideaceae. It is known to occur from a single location in the Amazon rainforest of Bolivia.
Fuscidea multispora is a species of foliicolous (leaf-dwelling), crustose lichen in the family Fuscideaceae. Found in Bolivia, it is known to occur only in a single high-altitude locality in a national park, where it grows on the leaves of coniferous trees from the genus Podocarpus.
Biatora radicicola is a species of corticolous (bark-dwelling) and saxicolous (rock-dwelling), crustose lichen in the family Ramalinaceae. It is found in various locations in Europe, where it grows in sheltered and humid microhabitats, often on exposed root bark at the base of trees.
Astrothelium bullatum is a rare species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. Found in Bolivia, it was formally described as a new species in 2016 by lichenologists Adam Flakus and André Aptroot. The type specimen was collected in the Cotapata National Park and Integrated Management Natural Area at an altitude of 1,700 m (5,600 ft); there, in a mountainous Yungas cloud forest, it was found growing on bark. It is only known to occur at the type locality. The lichen has a strongly bullate thallus, and it is this feature to which the species epithet bullatum refers.
Robert Lücking is a German lichenologist. He is a leading expert on foliicolous lichens–lichens that live on leaves.
Pseudochapsa lueckingii is a species of corticolous (bark-dwelling), crustose lichen in the family Graphidaceae. It is known only from a single collection in São Paulo, Brazil.
Dictyomeridium is a genus of corticolous (bark-dwelling), crustose lichens in the family Trypetheliaceae. It has eight species.
Polymeridium xanthoexcentricum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. It is found in southwestern Bolivia.
Phlyctis lueckingii is a species of corticolous (bark-dwelling) lichen in the family Phlyctidaceae. Found in Sri Lanka, it was formally described as a new species by Gothamie Weerakoon and André Aptroot in 2016. The type was collected on the Dothalugala mountain, where it was found in a rainforest on the smooth bark of a tree. The species epithet honours lichenologist Robert Lücking.
Kalbographa lueckingii is a species of corticolous (bark-dwelling), crustose lichen in the family Graphidaceae. Found in southeastern Brazil, it was formally described as a new species in 2009 by Klaus Kalb. The type specimen was collected between Taubaté and Ubatuba at an elevation of 800 m (2,600 ft); there, in a more or less virgin tropical rainforest, it was found growing on the smooth bark of an old deciduous tree in the shade. It is only known from the type collection. The species epithet honours lichenologist Robert Lücking, "for his outstanding contributions to tropical lichenology".
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.
Platygramme lueckingii is a species of script lichen in the family Graphidaceae. It is found in Hainan Island in tropical China, where it grows on bark.
Aspidothelium lueckingii is a species of corticolous (bark-dwelling) in the family Thelenellaceae. Found in mountainous cloud forests in Bolivia, it was formally described in 2009 by lichenologist Adam Flakus. The type specimen was collected near Incachaca village at an elevation of 2,317 m (7,602 ft), where it was found growing on the bark of a pine tree. It is known only from the type locality. It is named in honour of German lichenologist Robert Lücking, "for his magnificent contribution to the knowledge of tropical lichens."
Dictyomeridium lueckingii is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. Found in Bolivia, it was formally described as a new species in 2016 by Adam Flakus and André Aptroot. The type specimen was collected by the first author from Entre Ríos near Soledad at an elevation of 1,700 m (5,600 ft). It is only known to occur at the type locality, in the Tucumano-Boliviano montane forest. The species epithet honours German lichenologist Robert Lücking, "for his magnificent contribution to the knowledge of tropical lichens, on the occasion of his 50th birthday".
