Two new anamorphic species belonging to the genus Erysiphe, viz. E. baliensis and E. sidae, are described in this study. Erysiphe baliensis was found on Gliricidia sepium in the Island of Bali, Indonesia, and on Wisteria japonica (syn. Millettia japonica) in Japan. Internal transcribed spacer sequences and the anamorph characters of the collections on the hosts of the two plant genera collected in Indonesia and Japan were identical to each other and considered to be conspecific. Erysiphe sidae found on Sida rhombifolia is an isolated species in the genus Erysiphe based on molecular phylogenetic data.
