The Pilocarpaceae are a family of crustose lichens in the order Lecanorales. The species of this family have a cosmopolitan distribution and have been found in a variety of climatic regions. Pilocarpaceae was circumscribed by Alexander Zahlbruckner in Adolf Engler's influential 1905 work Die Natürlichen Pflanzenfamilien.
Bacidina is a genus of lichens in the family Ramalinaceae. It was circumscribed by Czech lichenologist Antonín Vězda in 1990, with Bacidina phacodes assigned as the type species. Vězda included 11 species in Bacidina, which was originally classified in the Lecideaceae. These species had previously been placed in genus Bacidia.
Trichothelium is a genus of lichen-forming fungi in the family Trichotheliaceae. It has an estimated 40 species. The genus was circumscribed by Swiss lichenologist Johannes Müller Argoviensis in 1885.
Porina is a genus of lichens in the family Trichotheliaceae. A 2020 estimate places about 145 species in the widespread genus.
Topeliopsis is a genus of lichen-forming fungi in the family Graphidaceae.

Enterographa is a genus of lichens in the family Roccellaceae.
Lecanographa is a genus of about 40 species of lichens in the family Lecanographaceae. It was circumscribed in 1994 by José M. Egea and Pilar Torrente, with Lecanographa lyncea as the type species.
Gyalectidium is a genus of lichen-forming fungi in the family Gomphillaceae. A 2020 estimates placed 52 species in the genus. The genus was circumscribed by Swiss lichenologist Johannes Müller Argoviensis in 1881. He included 3 species: G. xantholeucum, G. dispersum, and G. filicinum; the last of these is now the type species of the genus.
Gyalecta is a genus of lichen-forming fungi in the family Gyalectaceae that contains 50 species. Gyalecta was circumscribed by lichenologist Erik Acharius in 1808.
Absconditella is a genus of lichenised fungi in the family Stictidaceae. The genus was circumscribed in 1965 by Czech lichenologist Antonín Vězda, with Absconditella sphagnorum assigned as the type species. Absconditella is characterised by gyalectoid apothecia with a hymenium that is not amyloid, without a dark pigment and thalli containing green algae as photobionts. The genus name means "hidden", a reference to the scant structure of the thallus and its small apothecia.
Fuscidea is a genus of crustose lichens in the family Fuscideaceae. It has about 40 species. The genus was circumscribed in 1972 by lichenologists Volkmar Wirth and Antonín Vězda, with Fuscidea aggregatilis assigned as the type species.
Vezdaea is a genus of crustose lichens in the monotypic family Vezdaeaceae, which itself is the only taxon in the order Vezdaeales. The genus was circumscribed by Elisabeth Tschermak-Woess and Josef Poelt in 1976. The genus name honours Czech lichenologist Antonín Vězda (1920-2008).
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.
Halecania is a genus of fungi in the family Leprocaulaceae. It has 22 species. The genus was circumscribed by Austrian lichenologist Michaela Mayrhofer in 1987, with Halecania alpivaga assigned as the type species. She created Halecania to contain species, formerly placed in Lecania, with the following characteristics: uniformly amyloid apical domes, paraphyses with dark brown apical caps, and halonate ascospores.
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.
