    Here are a couple of photos. It's like some fungus or mold growing in the mulch. How come? What is causing this?

    Moisture coupled with a good carbon source like mulch equals fungal growth.
    It's pretty common unless you use fungicides on a regular basis.

    Thanks, that's our mulch, and this is the first year we have ever gotten that. I was just wondering about it.

    At the company I used to work it, we called it dog vomit. But it's just fungus enjoying warm and moist condtions. It doesn't do anything other than look ugly thankfully.

    Just saw this on some of our mulch today (newly installed this year) and assumed it was puke because it was right by a Chinese restaraunt.
    Noticed it all over the place after that. Then one of us was brave enough to rake it over and it was full of spores (purple) and you could rake it back into the mulch like it was never there.

    One of the main reasons I do not use hardwood mulches. The dog vomit fungus ( slime mold) spores are almost impossible to remove from a homes siding when disturbed in various and sundry ways.

    Correction: it is the shotgun fungus that shoots its spores onto house siding. Still both are problems in hardwood type mulches.
