Arg.) J. Kalb & K. Kalb , comb. nov. ( Fig. 3A–D ) MycoBank MB817483 Basionym: ― Arthothelium puniceum Müll. Arg., Hedwigia 32: 133 (1893) ; Thelotrema puniceum (Müll. Arg.) Makhija & Patw. , Tropical Bryology 10: 213 (1995) ; Chapsa punicea (Müll. Arg.) Cáceres & Lücking, Libri Botanici 22: 54 (2007) . Thelotrema rhododiscum Homchant. & Coppins , The Lichenologist 34: 135 (2002) . Remarks: ―This species was considered a synonym of Cruentotrema cruentatum , but differs in the smaller and relatively narrower ascospores and the bright red to pinkish disc of the ascomata. Thelotrema rhododiscum is a synonym. The species appears to be the eastern paleotropical vicariant of C. cruentatum .
