Studies on the pathogenesis of Marssonina brunnea, M. castagnei and M. populi to susceptible poplars showed that germtubes penetrated poplar leaves directly by enzymatic activity and indirectly through stomata. Six days following inoculation, hyphae had ramified throughout palisade and mesophyll tissues causing penetrated cells to become moribund. Acervuli were formed within seven days of inoculation and conidia were released by rupture of the cuticle and upper epidermal wall.
