From the parts of the state with adequate rainfall, we have received reports of turf with white, black, gray, red, orange, purple, and or rust-colored powder (see photo). This is slime mold, a fungus-like organism that often occurs during prolonged warm and wet weather. Slime molds appear to damage turf, but their effects are only cosmetic. They do not infect plants, but instead grow only on the surface. Regular mowing will usually break up and disperse slime mold.
