A fungus determined as Sphaeroderma damnosum was 
present in foot-rot of grain. This fungus, with its conidial 
stage, Fusarium, is regarded as a saprophyte which can be- 
come a parasite and cause the disease.

Thinks that Leptosphaeria is the cause of the foot-rot, but 
it is accompanied by Ophiobolus, Pyrenophora, and other 
fungi. Claims that cultures prove the Coniosporium to -be 
the conidial form of Ophiobolus graminis.

Pyrenophora, Dictyosporium, and Aspergillus are described. 
Author holds a Leptosphaeria to be the primary cause and 
the Ophiobolus a secondary cause. Leptosphaeria arises from 
the superficial mycelium. A Coniosporium belongs to the 
Ophiobolus. In October, pots of earth were irrigated with 
water bearing suspension of spores of Leptosphaeria and 
Ophiobolus. The plants were dead on February 15 from 
Lepto phaeria. Ophicbolus gave negative results. The roots 
were black. Leptosphaeria is brown when superficial, hyaline 
when internal. Attachments were present. Perithecia are 
free or immersed. Morbid histology is described. Ophiobolus 
forms flecks, superficial, adherent, distinguished by different 
attachments.
