Phyllosticta sojaecola was consistently isolated from pod lesions on field-grown soybean plants. Lesions had purplish red borders surrounding lighter, brownish centers and contained numerous dark pycnidia of P. sojaecola. Leaves of greenhouse-grown Forrest soybeans inoculated with P. sojaecola developed irregularly shaped lesions with a dark purple border enclosing a lighter inner zone. Pycnidia developed in these lesions from which P. sojaecola was reisolated.
