The presence of slime mold on turfgrass is more of a curiosity than a problem.
Slime molds are primitive organisms that are considered fungi.
They feed on decaying organic manner and other organisms in the thatch layer and soil. Slime molds often appear after a warm summer rain. At first a slimy growth, called the plasmodium, appears. This slimy growth dries into a powdery mass of spore-bearing structures that coat grass blades. Slime molds usually last one to two weeks and often are observed in the same spot year after year.
