Importance and distribution
Species of Cercostigmina are plant pathogenic showing as leaf spots on various hosts. There are 18 Cercostigmina epithets in Index Fungorum (2022), but most of the species have been transferred to Mycosphaerella and Pseudocercospora. Cercostigmina comprises three species known on several host plants in Apocynaceae, Asparagaceae, Fabaceae, Meliaceae, Myrtaceae, Proteaceae and Rutaceae. Cercostigmina has been reported mainly from Australia, Europe (Ukraine), South Africa and the The United States (New Jersey, Utah).
