my best guess (and it is just a guess) is fuligo septica http://msucares.com/newsletters/pests/infobytes/images/fuligo.jpg
Sorry, not finding anything (though I'm not an expert). Resources for slime molds are few and far between, I'm afraid.
I agree, looks like the scrambled-egg Slime (Fuligo septica) that happens to be red rather than yellow.
