Common Smut

Symptom

It can occur on all plant parts above ground. Large (2-10) cm galls are formed on leaves, stalks, tassels and ears. The galls are first covered by a silvery-white membrane, which changes to a grey mass containing black powdery spores. Early infection may kill young plants. Infection of ears is usually from spores germinating on the silks and mycelia growing down the silks to infect the kernels.
