DEF

The common smut of Indian corn caused by a fungus (Ustilago maydis) and characterized by grayish white swellings that rupture to expose a black spore mass.

CONT

Like other smut diseases, common smut of corn derives its name from the sooty masses of teliospores found on infected host plants ... The most obvious symptoms are tumor-like galls that vary in size from less than 1 cm to more than 30 cm (0.4-12 inch) in diameter. All meristematic tissues are susceptible to infection. Galls are found most frequently on ears, tassels, stalks, nodal shoots, and mid-ribs of leaves ... Even though galls may form on many above-ground parts of the plant, infection is local (i.e., the host is not colonized systemically). Occasionally, galls develop beneath the soil surface when the apical meristem of a young plant is infected.

OBS

Although Ustilago maydis occurs throughout the world where corn is grown, the occurrence of common smut is localized in Australia where the disease is known as "maize boil smut".
