The production of toxic substance by the fungus on culture medium was found to be possible over a wide range of sugars as the basal medium, the strength of the toxicity being in proportion to the power of enzymatic decomposition of various sugars. The toxic substance is produced comparatively rapidly in a medium containing glucose or sugars which are easily decomposed to glucose. In various grains incubated for 14 days after inoculation of this fungus, only the malt grains showed toxicity, the maltose having been consumed to a large extent. The toxic substance produced in this case was the same as that obtained from the culture medium containing glucose. The toxic substance corresponded to the composition of C7H6O4 and the toxicity, LD50, was 15.6mg./kg. in mouse.
