Enterographa is a genus of c. 30, mainly tropical, species included in the family Opegraphaceae. It contains corticolous, saxicolous and foliicolous taxa. Useful information on the genus is found in the accounts of Redinger [ Feddes Repert. 45: 171-177 (1938)] and Santesson [ Symb. bot. upsal. 12: 104-108 (1952)]. The genus is much in need of study and collection in New Zealand. Five species are recorded here.
