On the glumes small, dark spots are produced, on which spore-bearing bodies are relatively rare. On the stem the attack usually occurs at the joints, which shrivel, turn brown and later become sparingly dotted with black spore-bearing bodies. Glume blotch spots on the sheaths are dark brown and often so large as to include most of the sheath, while those on the blade of the leaf are light colored in the center and bordered with brown.

In the light area a few black spore- bearing bodies appear on both leaf surfaces. Glume blotch should not be confused either with black chaff
