Remarks (internal):Diploschistes scruposus, the other species of this genus known from South Korea and reported here as new record, differs in having urceolate ascomata, while ascomata in D. actinostomus are perithecioid. Diploschistes diploschistoides (Vain.) G. Salisb., a related species with perithecioid ascomata, differs in longer (30-52 µm), amyloid spores. For further descriptions see Mangold et al. (2009).
