André Aptroot is a Dutch mycologist and lichenologist.
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.
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.
Xanthoparmelia salazinica is a species of lichen in the family Parmeliaceae. Found in South Africa, it was described as a new species in 1989 by American lichenologist Mason Hale. He classified it in Karoowia, a genus that has since been placed in synonymy with Xanthoparmelia following molecular phylogenetic analysis published in 2010.
Carbacanthographis acanthoamicta is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Papua New Guinea, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected from a primary montane forest in Myola at an altitude of 2,100 m (6,900 ft). It is only known to occur at the type locality. The lichen has an olive to yellowish brown thallus with a thin cortex and an underlying prothallus. Its ascospores number 8 per ascus, are hyaline and measure 17–20 by 8 μm; they have from 7 to seven transverse septa and from 0 to two longitudinal septa. Carbacanthographis acanthoamicta contains salazinic acid, a lichen product than can be detected using thin-layer chromatography. The specific epithet alludes to its similarity with Carbacanthographis amicta.
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 latispora is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Venezuela, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected near the savannah of La Esmeralda ; here, in the Amazon rainforest, the lichen was found growing on a dead branch. It is only known to occur at the type locality. It has a whitish-grey thallus that lacks both a cortex and a prothallus. Its ascospores typically measure 140–155 by 30–35 μm and have from 13 to 17 transverse septa. The specific epithet refers to its unusually broad ascospores. Stictic acid, cryptostictic acid, and constictic acid are lichen products that occur in this species.
Carbacanthographis megalospora is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Brazil, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected by the first author from the Augusto Ruschi Biological Reserve at an altitude of 800 m (2,600 ft). The lichen has a whitish grey thallus with a thin cortex and an underlying black prothallus. Its asci contain a single ascospore. These spores are hyaline, and typically measure 235–255 by 30–40 μm. The specific epithet alludes to the large spores, the largest known in genus Carbacanthographis. C. megalospora contains stictic acid, cryptostictic acid, and constictic acid, which are lichen products that can be detected using thin-layer chromatography.
Carbacanthographis pseudorustica is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in insular Malaysia, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected in 1965 by American lichenologist Mason Hale from a virgin peat dipterocarp forest in the Sungai Assan logging area (Sarawak). It is similar to Carbacanthographis halei, but has larger ascospores. The specific epithet pseudorustica recalls Allographa rustica, the name of a lookalike species that Hale had originally applied to his collections of this lichen.
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.
Carbacanthographis spongiosa is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Brazil, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected from Atlantic Forest on a private property in Santa Luzia do Itanhy (Sergipe). The specific epithet spongiosa refers to the spongy texture of the thallus surface.
Carbacanthographis sipmaniana is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Malaysia, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected from a montane rainforest in Kinabalu Park, at an elevation of 1,800 m (5,900 ft). It is only known to occur at the type locality. The specific epithet sipmaniana honours lichenologist Harrie Sipman, "in recognition of his valuable contribution to tropical lichenology".
Carbacanthographis salazinicoides is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Papua New Guinea, it was formally described as a new species in 2022 by Shirley Cunha Feuerstein and Robert Lücking. The type specimen was collected by André Aptroot from a primary montane forest in Myola, at an elevation of 2,100 m (6,900 ft). It is only known to occur at the type locality. The specific epithet salazinicoides refers to its resemblance with Carbacanthographis salazinica, from which it differs by having larger ascospores.
Graphina is a genus of script lichens in the family Graphidaceae. It has about 25 species. The genus was circumscribed in 1880 by Swiss lichenologist Johannes Müller Argoviensis. Müller Argoviensis did not indicate a type species for the genus in his original publication; David Hawksworth proposed to designate Graphina anguina as a lectotype in 1981.
