“There appeared to be a constriction of one or more joints 
of the plant, and at the base of the stems there were indica- 
tions, in the form of sooty spores, of a fungus disease. The 
samples were sent to Mr. D. McAlpine, who states that he 
finds the wheat attacked by the fungus disease known in 
Europe as the ‘wheat-stem killer’ (Ophiobolus herpotrichus). 
This is the first recorded instance of the disease in Australia, 
though it has probably existed here for some years.”

Inoculations were made with watery suspension of spores 
of Leptosphaeria and Ophiobolus. L. herpotrichoides caused 
disease; Ophiobolus caused disease only rarely, and is secon-

“The wheat plant makes a start all right, but before the 
stalk appears the green color fades and the outer leaves be- 
come yellow. When the stalk is developed it soon becomes 
stunted, and never matures the ear. The entire plant soon 
dies, and this is the case over the affected area. The roots, 
too, have a very characteristic appearance. They are stunted 
and deformed at an early stage. * * * The occurrence of the 
disease in patches is another feature.’ In many instances 
the basal portion of the stem was considerably blackened, 
and on the inner surface of the sheaths the fungus Ophiobolus
