Leiorreuma is a genus of c. 7 species included in the family Graphidaceae. It is characterised by lirellae of variable shape, with a prominent thalline margin that sometimes breaks across the hymenium forming smaller, circular apothecia; a carbonised exciple that is continuous below the hymenium forming a thick, carbonised hypothecium; 8-spored, Graphis-type asci; and brownish, transversely septate, thick-walled ascospores. It occurs in both tropical and temperate biomes. One species is known from New Zealand.
