An intercellular matrix was observed to develop in normal cytoplasmic male-fertile corn lines infected by either race O or race T of Helminthosporium maydis. It usually occurred at the junction of necrotic and healthy cells but did not develop in infected Texas cytoplasmic male-sterile corn lines. Cytochemical tests indicated that the matrix was proteinaceous and ultrastructural examination showed that it was fibrous.
