host specificity of Exobasidium species

Exobasidium species are specialised on specific hosts or some closely related host species. However, in many cases (and books) they are referred to by older names, when broader species concepts were applied. A thorough revision has been done for fungi of this genus occurring in Europe, however, not on a world-wide scale and this adds to some complication as naming in other parts of the world therefore in most cases refer to the older names. On azalea galls are usually formed by E. japonicum.
