Biatora Meiocarpa (NYL.) Arnold, a Misunderstood Species
Abstract Biatora meiocarpa (Nyl.) Arnold (Lecanorales, lichenized Ascomycotina) is described and compared with some of its relatives, particularly B. helvola Körber ex Hellbom (syn. Lecideahelvola ), a species with which it has often been confused. Biatora meiocarpa and B. helvola differ in (1) widt...
