The Graphidaceae are a family of lichens in the order Ostropales.
Ochrolechia is a genus of crustose lichens in the family Ochrolechiaceae.
Diorygma is a genus of lichenized fungi in the family Graphidaceae. The genus was circumscribed by Franz Gerhard Eschweiler in 1824. Species of the genus are widely distributed in tropical and subtropical regions of the world.
Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909.
André Aptroot is a Dutch mycologist and lichenologist.
A corticolous lichen is a lichen that grows on bark. This is contrasted with lignicolous lichen, which grows on wood that has had the bark stripped from it, and saxicolous lichen, which grows on rock.
Graphis crebra is a species of corticolous lichen in the family Graphidaceae. It has a pantropical distribution. Like other script lichens, it grows on bark and resembles calligraphy. It can be distinguished from several other similar species by the white pruina (powder) on its apothecial discs.

He has authored 2282 species names, and 67 genera in the field of mycology.
Helge Thorsten Lumbsch is a German-born lichenologist living in the United States. His research interests include the phylogeny, taxonomy, and phylogeography of lichen-forming fungi; lichen diversity; lichen chemistry and chemotaxonomy. He is the Associate Curator and Head of Cryptogams and Chair of the Department of Botany at the Field Museum of Natural History.
Alan W. Archer is a mycologist and taxonomist. He is currently an honorary research associate at Royal Botanic Gardens Sydney. He uses chemotaxonomy as well as morphological features in taxonomy and to devise keys, most recently for the genus Pertusaria in the Australasia region.
Pertusaria ambigua is a lichen in the family Pertusariaceae, and found in New South Wales, growing on trees.
Klaus Kalb is a German lichenologist and an authority on tropical lichens.
Salazinic acid is a depsidone with a lactone ring. It is found in some lichens, and is especially prevalent in Parmotrema and Bulbothrix, where its presence or absence is often used to help classify species in those genera.
Pertusaria salazinica is a species of crustose lichen in the family Pertusariaceae. Found in Australia, it was described as a new species in 2017 by lichenologists Alan Archer and John Alan Elix. The type specimen was collected in Tully Gorge National Park (Queensland) at an altitude of 885 m (2,904 ft). Here, in a montane rainforest, it was found growing on a rotting log. The specific epithet refers to the presence of salazinic acid, a major secondary compound in the lichen. It also contains norstictic acid as a major metabolite, and connorstictic acid as a minor metabolite. Pertusaria salazinica is only known from the type specimen.
Phaeographis salazinica is a species of script lichen in the family Graphidaceae. Found in the Solomon Islands, the lichen was first described as a new species in 2003 by Australian lichenologist Alan W. Archer. He named it Phaeographis salazinica, with the specific epithet referring to the presence of the compound salazinic acid as its major secondary compound. The lichen also contains trace amounts of consalazinic acid, connorstictic acid, norstictic acid, subnorstictic acid, protocetraric acid, and methyl norstictate. The type specimen was collected near Tatamba on Tanabuli Island. The main morphological characteristics of Phaeographis salazinica are the conspicuous lirellae, and the large brown muriform ascospores. Archer transferred the taxon to the genus Phaeographis in 2007.
Carbacanthographis salazinica is a species of script lichen in the family Graphidaceae. Found in Australia, it was described as a new species in 2001 by lichenologist Alan Archer. The type specimen was collected by Archer in Conglomerate State Forest. Here the lichen was found growing on the bark of a palm tree. Its thallus is thin and grayish-green, with conspicuous white lirellae measuring 1–4 mm long. The specific epithet refers to salazinic acid, the presence of which is a distinguishing characteristic of this species. The lichen also has trace amounts of other secondary chemicals, including consalazinic acid, norstictic acid, and protocetraric acid. In 2005 Archer transferred the taxon to genus Carbacanthographis.
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.
Austrographa is a genus of lichen-forming fungi in the family Roccellaceae. It has three species. The genus was circumscribed in 2013 by lichenologists Laurens Sparrius, John Elix, and Alan Archer, with Austrographa kurriminensis assigned as the type species. The genus had been published invalidly on two separate occasions. All three species in the genus were found in a mangrove stand in Queensland, Australia.
Robert Lücking is a German lichenologist. He is a leading expert on foliicolous lichens–lichens that live on leaves.
