Astrothelium komposchii is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. [1] Found in Venezuela, it was formally described as a new species in 2016 by Dutch lichenologist André Aptroot. The type specimen was collected by Josef Hafellner and Harald Komposch about 15 km (15,000 m) southwest of La Esmeralda ( Alto Orinoco Municipality) at an altitude of 110 m (360 ft); there, on the west bank of the Surumoni river, it was found growing on the bark of Goupia glabra. The species epithet honours Komposch. The lichen has a green, discontinuous thallus comprising rows of small, flattened lobes (almost squamulose in appearance) with a hyaline (translucent) cortex. The presence of the lichen does not induce the formation of galls in the host plant. No lichen products were detected in the collected specimens using thin-layer chromatography. [2] The main characteristics of the lichen distinguishing it from others in Astrothelium are the uncoloured hamathecium, and the dimensions of its ascospores (35–45 μm broad). [3]
