Diseased wheat was replanted in pots. Perithecia were 
first found in November. Some were of Leptosphaeria, others 
of Ophiobolus. On some plants both were present. He used 
sterile soil and seeds in pots and infected them with water 
holding spores. Three to four months later, traces of disease 
were present. He concludes that both Ophiobolus and Lepto- 
sphaeria can produce the disease. Close sowing increases 
disease.
