Slime molds are non-pathogenic fungi that occasionally dwell on many different turfgrass species. These saprophytes do nothing more than cause an unsightly appearance, and at most, may cause slight yellowing of tissue if persistent for several days.

Fruiting bodies can often be observed on the foliage of the grass, on clover and other weeds, and on the soil or thatch. Grayish white structures filled with purple spores which resemble ashes can often be found. Spots in the turf are usually irregular circles a few inches to a few feet (5 cm - 1 m) across. If wet, cool weather persists, large irregular areas may become covered with slime mold.
