About: Astrothelium dicoloratum

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Astrothelium dicoloratum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Venezuela, it was formally described as a new species in 2016 by André Aptroot. The type specimen was collected southwest of La Esmeralda (Alto Orinoco, Amazonas) at an altitude of 110 m (360 ft); here, in a rainforest, the lichen was found growing on the smooth bark of trees. The thallus is completely covered with bright orange pigment. There is a single ascospore in the asci. These spores are hyaline, ellipsoid in shape, with 9 to 11 septa and dimensions of 50–75 by 11–15 µm. Chemical analysis of the lichen using thin-layer chromatography revealed the presence of an unnamed anthraquinone.
