I live in Louisiana, and recently early in the mornings I have noticed what looks like someone drug an oil can thru lines in my grass. Upon closer looking, and touching- it is only on the surface. When touched it feels like a silk feeling. No damage to grass, washes away in rain...but I thought it could be a fungus of some kind. Since we are in extremely humid area. Does anyone know what it could be. Does not grow back after cutting grass, or once pulled off. Has me stumped.

I'm not sure what that would be. I suggest cutting some of the affected grass, putting it in a ziplock bag and taking it to your local extension office.

Mowing or light raking destroys the crusty fruiting bodies of slime molds. Washing the affected patches of turfgrass with a hard stream of water breaks up the slime mold and restores the lawn's beauty. Since slime molds may be more common on heavily thatched or poorly drained portions of a lawn, renovation of the affected areas should reduce the incidence of disease. Thatch can be removed by hand-raking or by using a dethatching machine. Aerating machines are available to aerate and loosen hard, packed soils. Slime mold may appear on mulch, pine straw or wood chips, as well. If so, it can be scooped up with a shovel and disposed of. Changing to another kind of mulch can prevent slime mold by removing its preferred host. There are no pesticide sprays recommended for slime molds, and no need to control these odd but harmless organisms. Slime molds usually disappear as quickly as they appear. Read more: LaGrange News

Will try all of the above. It's weird the pattern is never the same, and only in one patch. We have raised the grounds, as there are wetlands right behind the house. Sometimes it's a perfect circle,(which you probably can't see in Pic) and sometimes perfect lines. Only started in the last couple of weeks. Never have had it before. But will try anything. My lawn has to be mowed every 2 days it grows so fast.Thank you Douglas, and thank you Sherrie. I really appreciate it.

Are you certain that there's nothing under there that might be seeping up? Were the wetlands behind your house impacted by any oil spills? I'd have it tested.

We get this in Georgia. It goes away and doesn't seem to do any lasting damage.

Fairy rings, from decaying wood under the grass....I had this in my lawn, especially when wet, like from morning dew. You can live with it, as the decomposing under the grass will nourish the grass or use baking soda to stop it from doing what it is doing...the tree roots can take up to 14 plus years to create this act of nature.

Underground fairy rings...I say you should leave it be and just enjoy the phenomena.

It will pass in time. Watch for morel mushrooms, those followed for me. When you find them, pick them, go into your house, lock the door, close the curtains, sauté them in butter and enjoy! They are a delicacy!
