Sounds like a slime mold...one of nature's decomposers.

I recently have found the same bright yellow mold on my mulch in my flower beds. i have never seen any thing like it before. i took pictures of it and have showed it to many people and they haven't either. i have had 4 piles of it and it keeps coming back in different places. if you find out what it is, please let me know. thank you.

I since found out it is yellow slime mold, called (appropriately) by some the dog vomit fungus.

Gross, but totally harmless.

Scientific name: fuligo septica.

Here are a few good web pages:

When I first saw it, I thought my landscapers had put down contaminated mulch. Not true, it just happens, especially in wet damp weather.

Good luck!

I've got it, too. New hardwood mulch. Some orange, some yellow and some black. It goes away eventually.

I have just had this type of mold. I've been using all types of mulch at my home in Indianapolis, IN. and have never had this. But my home I'm working on up north about 50 miles around Nobelsville had just grown this type of mold and it was a fresh supply that we had just got at the end of July. When I went to clean it up, It gave a fine brown dust that wouldn't absorb water nor would water knock down the dust. A'm I still talking about the same kind of mold?

Probably. You've seen the images, you can decide best. The fine brown dust particles are spores. ;-) Remember...not to worry.

I work at a daycare where this same type of mold is appearing on an almost daily basis. So I read on one of the follow-ups that it is not harmful, but my question is if this would affect people with mold allergies?

I have a bright yellowish, orange mold on top of my mulch pile. It has black holes in it and some kind of black liquid weeping out of the black holes!! It is scary. Could anybody help me and tell me what it is and if it is dangerous. Thanks!

Wear gloves and a mask and scoop out with a shovel. Mix one quarter cup bleach and about one and three quarter cups water mixture and pore it on where the mold was and where the spores still may be. In other words ....remove and kill :B

I have the fungus growing on my plants. Is this dangerous for eating and should the plant be destroyed.

I just want to reiterate that this slime mold is harmless. Gross, but harmless. Just think if it as the Blob and smile.

I've included a link that has information about their biology. Did you know that the whole thing you see is a single cell?

Fungi are really important to your garden. Yes, a few make your plants sick, but many, many more help build soil, provide nutrients to your plants, and one type (mycorrhizae) have a symbiotic relationship with 95% of plants that makes them grow better.

Why do people keep posting questions without reading the thread (which answers their questions) first? (I read the whole thread and it doesn't answer this question.)

AND I came here because I found a yellow dog vomit slime mold on the compost pile today & wanted to verify. Very cool stuff.

Truly a question for the ages...!

I'd personally like to thank dirt for dredging up this ancient thread, lol.

Mine was growing bigger and bigger as the day went on. Sort of a glow in the dark green. I thought at first the animals was shredding a green and yellow bush I had out there. Spray it with bleach. I know that isn't advisable but it turns it a different color and I will scoop and destroy tomm.
