S-type powdery mildew on lilac in Australia

In 2004, powdery mildew on lilac (Syringa vulgaris) was collected in a home garden in an inner suburb of Melbourne. At that time it could not be identified, but appeared to be the only verifiable record of powdery mildew on lilac in Australia. A recombinant DNA internal transcribed spacer sequence from a 2008 sample, collected from the same garden, revealed that the fungus is the S-type lilac powdery mildew that lacks a clear name.
