Fungus
Corticium fuciforme
Symptoms
Coral-pink to red fungus strands may be seen on leaves and leaf sheaths binding leaves together. Affected turf areas are usually more or less circular and vary from 2 to 15 inches in diameter. When dry, the pink strands resemble red threads. The infected leaf first appears water-soaked, but rapidly dies, becoming light tan. Leaves, and often the sheaths, are killed.
Grasses susceptible
Bentgrass, bermudagrass, bluegrass, fescue and ryegrass.
Conditions favoring disease
Red thread is most serious during periods of prolonged cool, wet weather, especially on turf deficient in nitrogen.
How fungus survives
The fungus survives unfavorable conditions as pinkish or red gelatinous crusts of fungus threads. When conditions are favorable, the crusts resume growth and fungus threads infect leaves.
