Infected seedlings may show brown lesions on early leaves or die right after germination (dieback). Older plants feature brown decay of the lower leaves (sometimes with dark fruiting bodies in leave sheaths) and grayish-brown blotching of lower internodes that later moves up to the higher ones. Severely infected stems are rotten and can show orange fungal growth. Under adverse weather conditions they may break at ground level. Small, brown, water-soaked lesions can appear on florets, that can take on a bleached color in stages when they should still be green. Under warm and humid conditions, spikelet bases may exhibit orange fungal tissue and bracts can become purplish-brown.
