Abstract: | The surface structures of peridial cell walls (outer, side, and inner walls) of 40Gymnosporangium and 7Roestelia species were examined by scanning electron microscopy. These surface structures were classified into 10 types based on shape, size, and density of the processes. Surface structural types of each wall were stable within a species. Therefore, it is suggested that surface structure types of peridial cell walls could be used as important diagnostic characteristics ofGymnosporangium andRoestelia species.
