Badimia multiseptata is a species of lichen in the family Pilocarpaceae. Found exclusively in lowland rainforest environments of Thailand, it was described as new to science in 2011 by Khwanruan Papong and Robert Lücking. It is characterized by its vividly coloured apothecia and unique, campylidioid conidiomata.
Byssoloma spinulosum is a species of foliicolous) (leaf-dwelling) lichen in the family Pilocarpaceae. Found in Papua New Guinea, it was described as new to science in 2011. It is characterized by its unique beaked pycnidia that are predominantly developed along the margins of living leaves.
Calopadia editiae is a species of lichen in the family Pilocarpaceae. It is found in Tanzania, with a distribution that extends to Costa Rica and the Galápagos Islands. It can be found on leaves or bark and is characterised by its pale grey to brownish grey colour, rounded apothecia and distinctive pruina. Described as new to science in 2011, the species was named in honour of Hungarian lichenologist Edit Farkas.
Diorygma microsporum is a species of corticolous (bark-dwelling) crustose lichen in the family Graphidaceae. It was described as new to science in 2011. It has a neotropical distribution, and has been collected in Florida, Colombia, Brazil, and India. Notable for its small ascospores, this lichen thrives in undisturbed rainforests and serves as an indicator of forest health.
Ampliotrema cocosense is a little-known species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Cocos Island, Costa Rica, it was described as new to science in 2011. Its distinctive features include its large, muriform ascospores and a notable chemical composition.
Antonín (Toni) Vězda was a Czech lichenologist. After completing a university education that was postponed by World War II, Vězda taught botany at the Czech University of Life Sciences. In 1958, he was dismissed from his university position as a result of the restrictions placed on academic freedoms by the communist regime in power. He eventually was hired as a lichen researcher by the Czechoslovak Academy of Sciences, who allowed him to work from his apartment, which served also as an office and herbarium.
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.
Tapellaria parvimuriformis is a species of foliicolous (leaf-dwelling), crustose lichen in the family Pilocarpaceae. It is found in Thailand's Khao Yai National Park, where it grows in the shady understory of lowland rainforests.
Asterothyrium vezdae is a species of foliicolous (leaf-dwelling) lichen in the family Gomphillaceae. It is found in Bolivia, where it grows on the leaves of vascular plants in the Amazon rainforest. The lichen is distinguished from its closest relative, Asterothyrium octomerum, by the larger number of septa in its ascospores, and its and black apothecia.
Fissurina amyloidea is a little-known species of script lichen in the family Graphidaceae. It is found in the primary rainforests of Rondônia, Brazil. It is characterized by its weakly carbonizedlirellae and thick-walled, strongly amyloid ascospores. Despite its superficial similarity to Fissurina subfurfuracea, F. amyloidea exhibits unique anatomical features that set it apart from other species within the genus.
Acanthotrema kalbii is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. First classified as a new species in 2012, the lichen is found in Costa Rica, where it grows in partially shaded areas of disturbed primary forest within the montane rainforest zone. This lichen stands out from its close relative, A. brasilianum, primarily due to the internal structure of its larger ascospores. The inaugural specimen of A. kalbii used for the species' formal description, was located on tree bark in a montane rainforest in the Las Tablas Protected Zone. The lichen is recognisable by its grey-green thallus, which varies from smooth to uneven and produces slender isidia, tiny outgrowths, up to 2 mm in length.
Arthonia isidiata is a species of corticolous (bark-dwelling) crustose lichen in the family Arthoniaceae. Found in Central America, it is characterized by its thin, shiny thallus, and isidia that emerge from the surface. Discovered in Costa Rica's Corcovado National Park, and later recorded from Panama, this species thrives in lowland tropical coastal rainforests on smooth bark of smaller, often young trees.
Byssoloma fuscothallinum is a species of foliicolous (leaf-dwelling) lichen in the family Pilocarpaceae. Found in Colombia and French Guiana, it was formally described as a new species in 2006 by lichenologist Robert Lücking.
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.
Fissurina chrysocarpa is a little-known species of script lichen in the family Graphidaceae. Found primarily in the rainforests of Rondônia, Brazil, it is distinguished by its bright orange lirellae.
Fissurina duplicans is a little-known species of corticolous (bark-dwelling) script lichen in the family Graphidaceae. It is found in primary rainforests of Brazil. The lichen has an endoperidermal thallus and a double margin of lirellae, setting it apart from similar species.
