Yep, it's that time of year. Slime mold, AKA Dog-vomit mold. (Sorry, "there is no other way of putting it." ) Do a google search and you'll see lots of wonderful photos of this curiosity.

It's harmless and does no damage except to one's asthetic sensibilities. Scoop it up with a shovel and toss it somewhere out of sight.

It's harmless- dog vomit fungus.

BTW, I read somewhere that dog vomit fungus can actually move under its own power. Watch how you sit on that wall. ;-)

Ain't nature grand.

I had a slime mold bloom on top of my compost pile over the weekend. Its beautiful when it first appears, but then it turns brown and looks like vomit. I wasn't home over the weekend and missed the pretty phase. :-(
