What is a slime mold?

When it comes to reproduction and survival, slime mold is just like fungi. It’s also capable of some self-propulsion. You would think it’s a fungus or animal based on these facts, but this isn’t the case.

Despite the fact that it grows on a substrate and gets its moisture and nutrients from the air, this organism is not a plant. They are primitive, single-celled organisms that have spore reproduction and are part of the Fuligo group. The apparent absence of similarity to any recognized plant or animal group is one of the more surprising slime mold facts.

They don’t eat plant tissue, hence slime molds aren’t harmful to plants. Plant growth is unaffected by the presence of yellow mold in mulch, for example. Some slime molds, on the other hand, can coat sections of turf and even the blades of grass.

Plants are the primary source of food for the creature when it reaches a stage known as plasmodium. When the organism dries out, the plasmodium changes into spores and spreads. A dry crusty residue is all that’s left on the host as a result.

How does Slime Mold Develop?

Saprophytes are the ancestors of slime molds. Dead or decaying materials is broken down by these microorganisms as part of their feeding operations. Dead oak trees in the forest are decomposed by saprophytes while dead grass blades in the lawn are decomposed by saprophytes. Turf grasses can be infected by some saprophytes. Dollar Spot is the most prevalent saprophytic illness. Live grass blades are the food source for these organisms.

The Slime Molds, on the other hand, simply need grass blades as a framework for their spores. The organism generates little fruiting bodies that grow perpendicular to the leaf surface on the exterior. The fruiting bodies start out as being approximately the size of a pinhead, but as more spores are released, they become larger and larger. Dark blue to purple to gray are the colors of the fruiting bodies. Patches can range in size from a few inches to several feet in diameter when a significant number of fruiting bodies form on numerous grass blades in the turf.

When homeowners discover these little patches, they may notice a small “puff” of a powdery substance rise from the area when they kick it with their shoe. The slime mold is releasing spores into the air. Having a few patches of slime mold in your grass isn’t a big deal. It’s a positive sign that your grass has a lot of microbial activity, so it’s not necessarily a bad thing.

How To Treat Slime Mold

To remove a patch of slime mold, you can either wait for the spores to naturally fall away or you can use a broom and a stream of water to remove them. The spores can also be dislodged by regular mowing. Keep in mind that the spores that fall off will remain in the soil or the thatch and will sprout when the correct weather conditions are there.

A different species of slime mold that can grow in mulch in garden beds is known as Dog Vomit Slime Mold, so named because of the appearance of the slime when it is still fresh.

It may look bad, but it’s a normal part of life and shouldn’t be a worry.
