The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark.
Physcidia is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was circumscribed in 1862 by American lichenologist Edward Tuckerman.
Thelotrema is a genus of lichen-forming fungi in the family Graphidaceae, the family to which all taxa in the former Thelotremataceae now belong.
Hafellia is a genus of lichen-forming fungi in the family Caliciaceae. The genus has a widespread distribution, especially in tropical regions. The genus is named in honour of the Austrian lichenologist Josef Hafellner. The genus was proposed by the German lichenologist Klaus Kalb in 1986 to contain two bark-dwelling species, formerly in genus Buellia, with callispora-type spores. These ascospores have ridged walls, and are thin walled at their tips at early states of their differentiation.
Gassicurtia is a genus of lichenized fungi in the family Caliciaceae.
Pyxine is a genus of foliose lichens in the family Caliciaceae. The genus has a widespread distribution in tropical regions.
Enterographa is a genus of lichens in the family Roccellaceae.
Pyrrhospora is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855, with Pyrrhospora quernea assigned as the type species.
Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was circumscribed in 1994 by Gintaras Kantvilas and John Alan Elix. It was emended in 2008 by the inclusion of Pyrrhospora species containing the anthraquinone russulone in their apothecia and having a prosoplectenchymatous exciple. The family Ramboldiaceae was circumscribed in 2014 to contain the genus.
André Aptroot is a Dutch mycologist and lichenologist. His primary research focus is on biodiversity, particularly tropical lichens, encompassing systematics, floristic surveys, and taxonomic reviews. A prolific researcher, he has published more than 500 scientific papers and described hundreds of new fungal and lichen species.
Megalaria is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was circumscribed by Austrian lichenologist Josef Hafellner in 1984, with Megalaria grossa assigned as the type species.
Baculifera is a genus of lichens in the family Caliciaceae. It was circumscribed in 2000 by Bernhard Marbach and Klaus Kalb. Species in this genus are characterized by having bacilliform conidia typically measuring 8–11 μm long, and a non-inspersed hymenium. The genus is roughly similar in morphology to Buellia.
Sculptolumina is a genus of corticolous lichens in the family Caliciaceae. The genus was circumscribed by Bernhard Marbach in 2000, with Sculptolumina japonica designated as the type species.
Endohyalina is a genus of 10 species of corticolous lichens in the family Caliciaceae. The genus was circumscribed by Bernhard Marbach in 2000, with Endohyalina rappii designated as the type species.
Coenogonium is a genus of filamentous 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.
Eugeniella is a genus of mostly leaf-dwelling (foliicolous) lichens in the family Pilocarpaceae. It contains 13 species. The genus was circumscribed in 2008 by lichenologists Robert Lücking, Emmanuël Sérusiaux, and Klaus Kalb, with Eugeniella psychotriae assigned as the type species. This lichen was originally called Patellaria psychotriae by Johannes Müller Argoviensis in 1881. The seven species that were initially included in the genus had previously been placed in the genera Bacidia and Byssoloma. Several newly identified species from Australasia and Central and South America were later added. Most of the species grow on leaves, although four of the Australasian species grow on bark.
Henricus (Harrie) Johannes Maria Sipman is a retired Dutch lichenologist who specialised in tropical and subtropical lichens and authored or co-authored over 250 scientific publications. He was the curator of the lichen herbarium at the Berlin Botanical Garden and Botanical Museum from 1983 until his retirement in 2010.
Cratiria sorediata is a species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. It was first described as a new species in 2009. The type specimen was collected from Aldabra in the Seychelles.
