Phyllactinia ailanthi is a species of powdery mildew in the family Erysiphaceae. It is found in Asia and North America, where it affects the genus Ailanthus.[1]
Description
[edit]The fungus forms white, thin growth, later turning thick and grey-brown, on the undersides of host leaves. P. ailanthi, like most Erysiphaceae, is highly host-specific and infects only the genus Ailanthus. Other species reported from Ailanthus include Erysiphe platani (perhaps doubtfully) and Erysiphe alphitoides which have jumped hosts in Europe,[2] and Erysiphe quercicola from India,[3] all of which primarily affect the uppersides of leaves. Also found on this host genus are Pseudoidium ailanthi,[1] which covers whole leaflets and causes distortions, and Erysiphe delavayi,[4] found on stems or leaf undersides, appearing diffuse, whitish, and not thick or coloured.
Taxonomy
[edit]The fungus was formally described in 1961 with the basionym Phyllactinia suffulta f. ailanthi by Golovin and Bunkina. The form was elevated to a species in 1979 by Y.N. Yu and S.J. Han.
