It's a common, pretty harmless fungus thingie - often called slime mold, vomit mold and a few other colorful names. First time I found it in my sideyard out front, I I was sure the party animals next door had barfed in my yard! You can carefully remove it (when disturbed it releases tons of spores into the atmosphere) - or not - it's pretty self limiting. I just discovered another blob this morning - 'tis the season!

Ha! Thx for the info. Off to tell hubby he was right.....

The only thing in my garden that it hurts is ornamental grasses! Doesn't kill them, but suspends growth for awhile, so one afflicted grass looks 2 years behind its siblings.
