Causative fungi of net-type and spot-type lesions on barley were isolated and identified as anamorphs of
Pyrenophora teres and Pyrenophora japonica respectively. Comparison of morphological characteristics showed that isolates of the two species are separable on the basis of differences in colony texture, conidiophore shape, conidial arrangement and conidial dimensions. The two species could also be distinguished from each other on account of adult-plant reactions exhibited by Dampier barley after inoculation by various isolates from South Africa, one isolate from Germany and one isolate from Washington State in North America.
