Astrothelium lucidomedullatum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae.[1] Found in Ecuador, it was formally described as a new species in 2016 by Dutch lichenologist André Aptroot. The type specimen was collected by Harrie Sipman from the Reserva Biológica San Francisco (Cordillera Numbala, Zamora-Chinchipe) at an altitude of Шаблон:Convert; there, it was found in a rainforest growing on smooth bark. The lichen has a quite smooth and shiny, pale ochraceous-green thallus with a cortex but lacking a prothallus, covering areas of up to Шаблон:Convert in diameter. The medulla contains lichexanthone, a lichen product that causes its tissue to fluoresce when lit with a long-wavelength UV light.[2] The main characteristics of the lichen distinguishing it from others in Astrothelium are its ascospores, which number four per ascus and have dimensions of 80–115 by 25–35 μm; the presence of lichexanthone in the medulla; and the structure of the Шаблон:Lichengloss ascomata, which have separate ostioles and are covered by the thallus.[3]
