Key Distinguishing Feature
Circular patches of bleached, straw coloured dead grass appear in spring as the dormant grass regrows. Patches are also visible in autumn and winter after a series of unusually cool days or wet, cold weather. Patches are a few cm to 1m in diameter. Patches reappear and expand in the same spot for 3 or more years. After 2 to 3 years, the centres of active patches may remain alive, and the patch takes on a "ring-like" appearance. Roots of affected plants turn dark brown to black and are severely rotted. Regrowth of grass into affected patches is slow and patches may remain barren or fill with weeds.
