Astrothelium flavomeristosporum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae.[1] Found in Ecuador and the Philippines, it was formally described as a new species in 2016 by Dutch lichenologist André Aptroot. The type specimen was collected by American botanist Edward Elmer from Irosin (Sorsogon, Luzon), in 1916. The lichen has a smooth and somewhat shiny, greyish-green thallus with a cortex surrounded by a thin (0.1 mm wide) black prothallus line. It covers areas of up to 9 cm (3.5 in) in diameter, and does not induce the formation of galls in the host tree. No lichen products were detected in the species using thin-layer chromatography.[2] The main characteristics of the lichen distinguishing it from others in Astrothelium are its smooth to uneven thallus, its prominent, blackish, and exposed ascomata,[3] and its yellow hamathecium.[2]
