Fungi associated with foliar diseases of Tecoma stans in Tlaxcala, Mexico

摘要

During 2015, leaves, stems, and pods of Tecoma stans showing symptoms of galls, rust, and powdery mildew were collected from public gardens located in Panotla, Tlaxcala, Mexico. The fungi present in the tissues were characterized morphologically using light microscopy. Galls on leaves, stems, and pods and erumpent pustules on leaves were associated with two rust fungi, Prospodium transformans and P. appendiculatum. The fungus associated with powdery mildew symptoms was identified as Phyllactinia obclavata. To the best of our knowledge, this is the first report of P. obclavata causing powdery mildew in T. stans in Mexico.
