Hyphae were observed in the style, ovary wall, and nucellus of carpellate flowers of Zea mays inoculated with Sclerospora sorghi. The fungus was confined in mature seeds to the pericarp and pedicel. The embryo and endosperm were protected from the fungus by the aleurone layer which appeared to serve as a barrier. Infected plants developed from infected seeds planted when in the soft dough stage. Transmission was prevented by reducing moisture content to 9% and by storage for 40 days before planting.
