Bright yellow growth in my yard?

We recently had a tree stump ground up in our yard. I am sending you photos of a bright yellow growth near the chips from the grinding. What am I seeing here?

The slime mold in your photos, Fuligo septica, with the descriptive common names “dog vomit slime mold” or “scrambled egg slime,” is often found on mulch. It is noticeable because of its brilliant color, but do not worry, it is not harmful to humans, other animals or plants.

This slime mold is not a fungus. Instead, it’s a group of single-celled amoeba-like organisms that ingest bacteria and other smaller organisms found on wood chips. Check out this link for more information.
