Controversy (Contraversy?) on the nomenclature of Tilletia controversa

Tilletia controversa (EPPO A2 pest) has been the preferred name of dwarf bunt of wheat for EPPO, CABI and many scientists. According to a Swedish expert, however, the epithet controversa is not correct, because last but not least the original description of Khn stated contraversa. EPPO maintains its position on the grounds that the rules allow spelling mistakes in names to be corrected. Further contributions to this very important debate are invited.
