Hymenula cerealis Ellis & Everh. 1894 - (Cephalosporium stripe)

The fungus is an anamorphic, soilborne fungus causing the vascular wilt disease "Cephalosporium stripe" in wheat and other cereals. The symptoms are characterized by one to three broad yellow to brown leaf stripes which extend to the leaf sheaths and stems. In severe cases, wilting, necrosis, stunting and whiteheads follow. Seed weight and seed numbers are reduced and yield losses might reach 50%.

The fungus survives in plant debris and in the soil, where it penetrates the roots through small wounds, e.g. those caused by freezing. Short crop rotation, early fall planting and cool and wet weather promote the disease. Management relies mainly on burning crop residues, deep ploughing, increasing the soil pH and rotation with other crops. Resistant cultivars are under development
