| | Slime molds often appear in the same area of the lawn year after year in four to six inch patches in various shades of purple, gray, white or cream. | | | The spores, capable of surviving unfavorable weather, are spread by wind, water, mowers, or other equipment. | | | Some slime molds produce cream-colored masses of cells along grass blades. |

| | Slime Molds on Turfgrass, HYG-3074-96 |
| | Slime molds may be found on all cultivated and weedy grasses. | | | Plant vigor may be slightly reduced in severely colonized turf due to excessive growth of the fungus on leaves causing a shading of the leaf surface and leading to a reduction in photosynthesis. | | | In the case of heavy spore production, some yellowing or chlorosis of the leaves may be observed due to shading of the turf causing reduced photosynthesis. |

| | Slime Mold: The Blob on the Lawn |
| | Slime mold for the most part is a beneficial organism that decays dead plant material, returning nutrients to the soil. | | | The most common forms on turf resemble small purple or black ball attacked to a blade of grass or a readily noticeable creamy-white to yellow-orange jelly-like mass situated on the lawn. | | | After an extended period of heavy rain an organism known as Slime Mold (Mucilago sp., Physarum sp., Fuligo sp.) may appear in your lawn. |

| | Frequent mowing and removal of the fruiting structures from plant parts by raking or watering is generally sufficient to improve the appearance of the plant. | | | Heavy infestations of slime mold may cause a slight leaf yellowing resulting from partial shading of the photosynthetic area. | | | Although unsightly, the slime molds do not parasitize living plants. |

| | Unlike more advanced slime fungi, the spores are not produced in distinct spore cases called sporangia. | | | This stage composed of amoeboid and flagellated cells is why some authorities place the slime molds in the kingdom Protoctista. | | | As the diploid nuclei divide, the plasmodium grows larger and larger, slowly moving (creeping) along the forest floor and feeding like a giant amoeba. |

| | Slime Mold in Turfgrass Colorado State University Cooperative Extension Tri River Area Mesa Delta Montrose and Ouray ... |
| | Colonies of slime mold in turf can cover single blades of grass but are more commonly found in masses four to six inches across. | | | Once the spore masses have formed on the grass blades, mowing, raking or watering is normally sufficient to remove the fruiting structures from the grass blades. | | | Due to the reduction of light reaching the grass plus interference with respiration and transpiration, colonies of slime mold coating the blades can eventually result in the death of the grass. |

| | Molds are usually inconspicuous until they begin to reproduce, then they are familiar to many people as the cause of food spoilage and crop infestation. | | | These masses, called slime molds, cannot readily be classified as either plants or animals because they exhibit certain essential characteristics of both. | | | During one of their growth stages, they are protozoa-like because they lack cell walls, have amoeboid movement, and ingest particulate nutrients. |

| | These "giant cells" have been extremely useful in studies of cytoplasmic streaming (the movement of cell contents) because it is possible to see this happening even under relatively low magnification. | | | In addition, the large size of the slime mold "cell" makes them easier to manipulate than most cells. | | | Cellular slime molds are thus of great interest to cell and developmental biologists, because they provide a comparatively simple and easily manipulated system for understanding how cells interact to generate a multicellular organism. |
