Thalloloma janeirense is a rare species of corticolous lichen in the family Graphidaceae. It has been reported from Brazil, [1] Fiji, [2] the Philippines [3] and the Seychelles. [4]
The Graphidaceae are a family of lichens in the order Ostropales.
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.
Myriotrema is a genus of lichen-forming fungi in the family Thelotremataceae.
André Aptroot is a Dutch mycologist and lichenologist.
Myriochapsa psoromica is a species of lichen in the family Graphidaceae. Found in Brazil, it was described as new to science in 2011 as a species of Chapsa. The taxon was transferred to Myriochapsa in 2013.
Parmotrema abessinicum is a species of corticolous lichen in the family Parmeliaceae. It has been recorded from Africa, Asia, and Oceania.
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.
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.
Allographa leptospora is a species of script lichen in the family Graphidaceae. The lichen was first formally described in 1921 by Finnish lichenologist Edvard August Vainio as Graphis leptospora. The type specimen was collected in 1904 by German botanist Carl Curt Hosseus on Doi Suthep, where it was found growing on tree bark. Hosseus sent this and other lichens collected from Thailand to Vainio for identification. Robert Lücking and Klaus Kalb transferred it to the genus Allographa in 2018. In 2016, the lichen was reported from the Sintra Mountains, Portugal, which was its first documented occurrence in Europe.
Allographa aptrootiana is a species of script lichen in the family Graphidaceae that is found in tropical Africa. It was formally described as a new species in 2014 by Dries Van den Broeck, Robert Lücking, and Damien Ertz. The type locality is Yaengo (Orientale Province, Democratic Republic of the Congo; here it was found growing on the bark of an unidentified tree species in an evergreen forest. The lichen somewhat resembles Graphis tetralocularis in overall morphology, but unlike that species it has a completely carbonized excipulum, and does not produce the secondary compound atranorin. The holotype specimen is parasitised with Etayoa trypethelii, a widespread tropical lichenicolous fungus. The specific epithet aptrootiana honours André Aptroot, "in recognition of his many contributions to tropical lichenology". The taxon was transferred to Allographa in 2018 following a reinstatement and reorganization of that genus.
Astrochapsa is a genus of lichen-forming fungi in the subfamily Graphidoideae of the family Graphidaceae. It has 28 species. The genus was circumscribed by Sittiporn Parnmen, Robert Lücking, and H. Thorsten Lumbsch in 2012, with Astrochapsa astroidea assigned as the type species. It was segregated from the genus Chapsa, from which it differs in having a more frequently densely corticate thallus, an apothecial margin that is mostly recurved, and the almost exclusively subdistoseptate, non-amyloid ascospores.
Halegrapha is a genus of lichen-forming fungi in the family Graphidaceae. It has nine species. The genus was circumscribed in 2011 by Eimy Rivas Plata and Robert Lücking, with Halegrapha chimaera assigned as the type species. The generic name honors American lichenologist Mason Hale.
Leucodecton fuscomarginatum is a species of lichen in the family Graphidaceae. Found in Sri Lanka, it was formally described as a new species in 2014 by lichenologists Gothamie Weerakoon, Robert Lücking, and Helge Thorsten Lumbsch. The type specimen was collected from the Kikiliyamana Tea Estate at an altitude of 1,280 m (4,200 ft). The lichen, which is known to occur only at the type locality, grows in disturbed vegetation. The specific epithet fuscomarginatum refers to the rims of the ascomata pores, which are typically brown in colour. Leucodecton fuscomarginatum has a shiny, smooth, light greenish to yellowish brown thallus measuring 50–100 μm thick with a thin cortex. The ascospores are muriform, ellipsoid in shape, and measure 30–40 by 10–12 μm. Secondary chemicals present in the lichen include stictic acid, constictic acid, acetylconstictic acid, and hypostictic acid.
Carbacanthographis aggregata is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Asia, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected from the Gunung Pulai Forest Reserve in Johor (Malaysia) at an altitude of 150 m (490 ft). It has also been recorded from the Tai Po Kau Nature Reserve in China. The lichen has a greenish grey to grey thallus that lacks a cortex, but has a black prothallus. Its ascomata are aggregated in small clusters; it is this characteristic that is referred to in the specific epithet aggregata. The lichen contains salazinic acid and trace amounts of norstictic acid; these are lichen products that can be detected using thin-layer chromatography.
Carbacanthographis subchionophora is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Papua New Guinea and Brazil, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected from Kagi Village. It is similar to Carbacanthographis chionophora, but unlike that lichen, it does not contain lichexanthone. The specific epithet subchionophora refers to its resemblance with this species.
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.
Heiomasia is a genus of corticolous (bark-dwelling), crustose lichens in the family Graphidaceae. It has five species.
Cruentotrema is a genus of corticolous (bark-dwelling) lichens in the family Graphidaceae. It has seven species.
