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.
Platythecium is a genus of lichen-forming fungi in the family Graphidaceae. It contains an estimated 27 species.
Platygramme is a genus of lichen-forming fungi in the family Graphidaceae consisting of about 30 species. The genus was circumscribed by Antoine Laurent Apollinaire Fée in 1874.
Phaeographis is a genus of lichen-forming fungi in the family Graphidaceae. It has an estimated 180 species.
Hemithecium is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Vittore Benedetto Antonio Trevisan de Saint-Léon in 1853.
Graphis is a genus of lichen-forming fungi in the family Graphidaceae. Historically, Graphis was used as a broad category for species with colourless, transversely septate ascospores within the Graphidaceae. However, with advances in genetic research, this classification has become more refined. As a result, species previously classified under Graphina have been re-assigned to Allographa or Graphis. The species complex around Graphis scripta has also been recognised, leading to the identification of several new species, many of which may have been previously overlooked.
Fissurina is a genus of lichenized fungi in the family Graphidaceae. It has about 160 species, most of which are found in tropical regions.
Carbacanthographis is a genus of corticolous (bark-dwelling) lichens in the family Graphidaceae. The genus was circumscribed by German lichenologists Bettina Staiger and Klaus Kalb in 2002. An updated worldwide key to the genus was published in 2022 that added 17 new species. This revision allowed for further identification of undescribed species from other collections, and subsequently, 14 species were added in 2023 from the Amazonian lowland forests of Brazil and the Guianas.
Anomomorpha is a genus of lichens in the family Graphidaceae. The genus, described in 1891, has a pantropical distribution.
Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909.
Chapsa is a genus of lichens in the family Graphidaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1860.
Cryptothecia is a genus of white to greenish crustose lichens that grow on bark, wood, or leaves, in tropical or subtropical areas worldwide. It has a conspicuous prothallus that develops around its periphery which can be bright red in some species, hence the common name wreath lichen. The main vegetative body (thallus) lacks a cortex (ecorticate and is often immersed in the substrate or byssoid. The medulla is white, well defined, and often peppered with calcium oxalate crystals. Ascomata are not well defined, being cushions of soft white mycelium immersed in the medullary tissue, hence the name from the Greek krypto = "to conceal" and theke = "a container or sheath". It contains Trentepohlia, a green alga, as its photobiont partner.
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.
Diorygma sticticum is a species of corticolous (bark-dwelling) script lichen in the family Graphidaceae. It was described as new to science in 2011. It is found in lowland rainforests in Thailand, and in southwestern India.
Allographa is a genus of script lichens in the family Graphidaceae. It has nearly 200 species. Formally circumscribed in 1824 by François Fulgis Chevallier, Allographa was formerly included in Graphis, but was upgraded to generic status in 2018 by lichenologists Klaus Kalb and Robert Lücking, who used molecular phylogenetics analysis to show this group of species to constitute a distinct lineage in the Graphidaceae.
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. Between 1990 and 1997 he edited and distributed the exsiccata Lichenotheca Latinoamericana a museo botanico Berolinensi edita.
Graphidales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 6 families, about 81 genera and about 2,228 species. Family Graphidaceae are the largest crustose family within Graphidales order comprising more than 2000 species, which are widely distributed in tropical and subtropical regions of the world.
Leiorreuma is a genus of script lichens in the family Graphidaceae. It has 18 species. The genus was circumscribed by Franz Gerhard Eschweiler in 1824, with Leiorreuma hepaticum assigned as the type species.
Pallidogramme is a genus of lichen-forming fungi in the family Graphidaceae. It has 8 species of corticolous (bark-dwelling), crustose lichens.
