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.
Melanotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by German lichenologist Andreas Frisch in 2006, with M. platystomum assigned as the type species.
Leucodecton is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 1860 by Swiss lichenologist Abramo Bartolommeo Massalongo, with Leucodecton compunctum assigned as the type species.
Chapsa is a genus of lichens in the family Graphidaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1860.
Thelotrema is a genus of lichen-forming fungi in the family Graphidaceae, the family to which all taxa in the former Thelotremataceae now belong.
Stirtonia is a genus of lichenized fungi in the family Arthoniaceae. It has at least 21 species.
Malmidea is a genus of crustose lichens and the type genus of the family Malmideaceae. It was established in 2011 to contain a phylogenetically distinct group of species formerly placed in the genus Malcolmiella. Malmidea comprises more than 50 mostly tropical species that grow on bark, although a few grow on leaves.
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.
Klaus Kalb is a German lichenologist and an authority on tropical lichens.
Wirthiotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2010 by Eimy Rivas Plata, Klaus Kalb, Andreas Frisch, and H. Thorsten Lumbsch, with Wirthiotrema glaucopallens assigned as the type species. Wirthiotrema contains species that were formerly considered part of the Thelotrema glaucopallens species group. The genus name honours lichenologist Volkmar Wirth, "for his numerous outstanding contributions to lichenology".
Rhabdodiscus is a genus of script lichens in the family Graphidaceae. It has 36 species.
Schizotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2009 by Armin Mangold and H. Thorsten Lumbsch.
Henricus (Harrie) Johannes Maria Sipman is a Dutch lichenologist. He specialises in tropical and subtropical lichens, and has authored or co-authored more than 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.
Cruentotrema is a genus of corticolous (bark-dwelling) lichens in the family Graphidaceae. It has seven species.
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.
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.
Clandestinotrema is a genus of lichen-forming fungi in the family Graphidaceae. It has 17 species. They typically inhabit montane and cloud forest at higher elevations in the tropics.
Topeliopsis acutispora is a species of crustose lichen in the family Graphidaceae. It is found in New South Wales and southern Queensland (Australia), where it grows on bryophytes.
Gintarasia is a genus of lichen-forming fungi in the family Graphidaceae. It has seven species, all of which are found in Australia. Gintarasia species are corticolous (bark-dwelling), crustose lichens with a thelotremoid form.
