Lyn - I've also discovered for the first time about "dog vomit mold". I'd never seen it before and it's quite disgusting. It actually looks like dog vomit! But it's 100% harmless and breaks down pretty quickly. It is more common with pine & other soft mulches apparently (from what research I did when I saw these giant piles of dog puke all over my yard that actually wasn't dog puke!) and from the humungo pile of mulch I got earlier this year, quite a bit of it was raw ponderosa pine chips (still sappy) and then with all the rain we got when I was putting down the mulch... yea, dogpuke everywhere. Yuck. Thank goodness it didn't smell or attract flies!
