The concentrations of seventeen elements in two species of fungus which cause wheat bunt disease,Tilletia caries (DC.) Tul. andTilletia controversa Kühn, were determined by instrumental neutron activation analysis. Differences in the K and Cl concentrations between these two species of spores are large and therefore can be used as a criterion for distinguishing between the two species of fungus.
