Scrambled egg slime is also known as dog vomit slime. It is common on dead wood, including wood mulch, in wet conditions. So no surprise this arrived this summer.
It was on a tree stump which was also playing host to a bracket fungus, probably some kind of polypore.
Twenty-four hours after these pictures were taken, all that was left of the slime was a dark stain on the wood where it had been.
