Cercospora Violae Sacc, producing white spots on leaves of the violet in the spring, is common in coldframe or garden culture. Cercospora Diospyri Thum. is of common occurrence in the south- ern states on leaves and fruit of persimmon (Diospyros virginiand). Cercospora sordida Sacc. is the most important disease-produc- ing fungus of the trumpet creeper {Tecoma radicans), in the United States. Pale spots are produced on the leaves, and defoli- ation of the host often results by midsummer. 1 Pierce, N. B. A Disease of Almond Trees. Journ.
