Abstract
One specimen of powdery mildew on Euphorbia cyathophora from Vanuatu and 11 specimens on E. cyathophora, E. dentata, E. heterophylla and E. leucocephala from Australia were studied. All were shown to represent the Oidiopsis anamorph of Leveillula taurica, which is described. This is the first record of Oidiopsis in Vanuatu. E. leucocephala is a new host record for this powdery mildew.
