- Abstract
A new lichenicolous ascomycete, Arthonia diorygmae, is described from the thallus and ascomata of Diorygma junghuhnii. The new species is characterized by rounded to irregular, applanate to convex ascomata up to 0·3 mm in diameter, a slightly whitish pruinose disc, transversely 1-septate, hyaline to greyish ascospores (13–)14–15(–21)×5–7 µm, and its lichenicolous habitat. It is known from the subtropical region of the Western Ghats in India and appears to be widespread due to the large distribution of the host species.
