Over the past few days I have noticed 5 spots like this on my grass. Each spot is about 5 inches around and after a few days the affected blades of grass turn black. Is this an insect or a fungus? Anyone know how to treat this?
This is what it looks like a few days later.
That is a slime mold usually will not kill grass. Mowing or raking will help knock the spores off the leaf blade. Make sure not to overwater.

Thank you Joneboy! We have had a lot of rain and heavy dew in my area. Thank you for the link and information.
