Abstract
Cereal pathologists have been isolating a fungus from stem bases, crowns and roots of wheat, barley and oats which is now identified as Phoma sclerotioides. Although this fungus has not been recorded previously from the Southern Hemisphere, it appears to be widespread in southern Australian dryland cropping systems. It has been isolated from a wide host range which extends over legumes and both grassy and broad-leaved weeds associated with cereai crops. The first recorded pathogenicity tests for cereal hosts are reported for isolates associated with dryland root-rot.
