Coenogonium is a genus of crustose lichens in the monotypic family Coenogoniaceae. It has about 90 species. Most species are leaf-dwelling or grow on bark, although a few are known to grow on rocks under certain conditions, and some are restricted to growth on termite nests. The genus was circumscribed in 1820 by German naturalist Christian Gottfried Ehrenberg.
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.
Coenogonium beaverae is a species of corticolous (bark-dwelling), crustose lichen in the family Coenogoniaceae. Found in Seychelles, it was formally described as a new species in 2017 by Robert Lücking and Paul Diederich. The type specimen was collected by the second author in a disturbed rainforest near the Sauzier Waterfall at altitudes between 20 and 70 m. It is only known from the type locality. The species epithet beaverae honours Katy Beaver, "who generously gave support and assistance during the field trip of the first author to several Seychelles islands, and who is extremely active in the protection of the environment in Seychelles".
Inoderma sorediatum is a species of crustose lichen in the family Arthoniaceae. It is only known to occur on the bark of trees in Poland's Białowieża National Park. It is differentiated from other species in genus Inoderma by the form of its thallus, which is entirely made of powdery, granular soredia, as well as by the presence of a unique combination of lichen products.
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.
Lecidella mandshurica is a species of corticolous (bark-dwelling), crustose lichen in the family Lecanoraceae. It is found in the Russian Far East, South Korea, and China.
Biatora oxneri is a species of corticolous (bark-dwelling) lichen in the family Ramalinaceae. It is found in the Russian Far East and in South Korea.
Biatora pacifica is a species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae. It is found in Russia, Japan, and South Korea, where it grows along the Pacific coast. It inhabits the bark of a variety of coniferous and deciduous plants.
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.
Coenogonium pineti is a species of crustose lichen in the family Coenogoniaceae. It was first formally described by Erik Acharius in 1810, as Lecidea pineti. Robert Lücking and H. Thorsten Lumbsch transferred it to Coenogonium in 2004 after molecular phylogenetic analysis suggested its placement in that genus. The lichen has a widespread distribution in cooler, temperate regions of the Northern Hemisphere, but has also been recorded from southeastern mainland Australia and Tasmania.
Gyalecta ancistrospora is a species of saxicolous (rock-dwelling), crustose lichen in the family Gyalectaceae. Found in Korea, it was formally described as a new species in 2014 by lichenologists André Aptroot and Kwang-Hee Moon. The type specimen was collected by the first author from Mount Juwang at an altitude between 330 and 520 m ; there, it was found growing on siliceous rock. It is only known to occur in this area, where it grows on boulders shaded by trees in forest.
Galbinothrix is a fungal genus in the family Chrysotrichaceae. It is monotypic, containing the single species Galbinothrix caesiopruinosa, a corticolous (bark-dwelling) lichen.
Robert Lücking is a German lichenologist. He earned his master's and PhD from the University of Ulm, focusing on the taxonomy, ecology, and biodiversity of foliicolous lichens. He has received numerous awards for his work, including the Mason E. Hale award for his doctoral thesis, the Augustin Pyramus de Candolle prize for his monograph, and the Tuckerman Award twice for his publications in The Bryologist. Since 2015, he has been serving as the curator of lichens, fungi, and bryophytes at the Berlin Botanical Garden and Botanical Museum, and several lichen species and a genus have been named in his honour.
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.
Coenogonium atherospermatis is a species of lichen in the family Coenogoniaceae. Found in Tasmania, it was formally described as a new species in 2018 by lichenologists Gintaras Kantvilas, Eimy Rivas Plata, and Robert Lücking. The type specimen was collected by the first author near Little Fisher River at an altitude of 820 m (2,690 ft), where it was found in a cool temperate rainforest growing on Atherosperma moschatum. It is locally abundant at this location, where it usually occurs at elevations of more than about 500 m (1,600 ft). The species epithet refers to the genus of the preferred host tree. Within Tasmanian rainforest vegetation, Atherosperma is known for harbouring "a distinctive suite of lichens", including C. atherospermatis.
Coenogonium australiense is a species of corticolous (bark-dwelling), crustose lichen in the family Coenogoniaceae. Found in Australia, it was formally described as a new species in 2018 by lichenologists Gintaras Kantvilas and Robert Lücking. The type specimen was collected by the first author near Little Fisher River (Tasmania) at an altitude of 880 m (2,890 ft), where it was found in a rainforest growing on Nothofagus cunninghamii. The species epithet australiense refers to its geographical distribution. In addition to Tasmania, the lichen has also been documented from New South Wales and Kangaroo Island. In the latter location it was found in remnant stands of coniferous woodland, where it was growing on the bark of old, fissured Callitris trunks.
Coenogonium urceolatum is a rare species of corticlous (bark-dwelling), crustose lichen in the family Coenogoniaceae. Found in western Tasmania, it was formally described as a new species in 2018 by lichenologists Gintaras Kantvilas, Eimy Rivas Plata, and Robert Lücking. The type specimen was collected by the first author near Piney Creek, about 10 kilometres (6.2 mi) north of Zeehan, where it was found in a cool temperate rainforest, growing on an old, dry, shaded trunk of Nothofagus cunninghamii. It is only known from the type collection. The lichen has a pale greyish-greenish thallus lacking a prothallus. The species epithet refers to its characteristic small, urn-shaped, orange apothecia.
Coenogonium barbatum is a species of foliicolous (leaf-dwelling) lichen in the family Coenogoniaceae. It is characterised by its distinctive beard-shaped growth, setting it apart from closely related species. Identified and named as a new species in 2006, the lichen has been specifically found at the La Selva Biological Station in Costa Rica. The species name barbatum hints at its beard-like appearance.
Coenogonium kalbii is a species of corticolous (bark-dwelling), crustose lichen in the family Coenogoniaceae. It has been found in variety of locations in the southern region of Costa Rica, primarily in humid, shaded microsites within low-mountain rainforest environments.
Neosergipea is a genus of lichen-forming fungi in the family Roccellaceae. It has four species, all of which are corticolous (bark-dwelling), crustose lichens that are found in the tropical forests of Brazil. This genus is related to the genera Dichosporidium, Enterographa, and Erythrodecton. It distinguishes itself through unique morphological characteristics and certain chemical constituents, in particular, its non-carbonised ascomata and the presence of a vivid orange anthraquinone compound.
