A goodrepresentation of its appearance is seen in Plate black masses consist of millions of minute spores,by means of wliich the fungus reproduces itself. Thespore masses ripen about tlie time tlie oats are in bloom,when the cliaif enveloping the embryo seed is spreadwide open. The spores are blown over the field, andmany of them lodge on the inner side of the chaff parti-cles, where they remain as the seed ripens, and are notdislodged when it goes through the threshing smut spores are also largely distributed from thesmutted heads and lodged in the chaff of sound kernelsduring threshing, although it probable that only asmall percentage of them get far enough into the chaffto infect the plants that develop from the kernels. After the spores have lodged in the chaff they re-main there until t
