While collecting conidial materials of powdery mildews, in order to compare the shape of the germ tube of the conidia, the writer has met with about one hundred host plants which have not been listed as host plants in the monographs of Homma (1937) and of Sawada (1951). Those new host plants are given in the present paper. The identification of the powdery mildew has been made in most cases by examination of the conidial stage. The shape of the germ tube of the conidia is very useful in aids in identification, although it may not be wholly satisfactory (Hirata 1942, 1955).
