bright yellow fungus #413575

Asked July 11, 2017, 8:41 PM EDT

I found this mustard yellow branch like, but dense, fungus growing on a tree stump in my yard. I did some research online, but can't figure out what it is and if it's dangerous. I've attached a few photos, one a close up. It's adjacent to my garden and not far from my house. Should I leave it alone or get rid of it?

Expert Response

Hello,

Thanks for the question. From the pictures it appears to be what is affectionately referred to as dog vomit fungus. It is a type of slime mold, which technically is not a true fungus. If that is what it is, dog vomit fungus is harmless to people, pets, and plants.

Enjoy your peculiar find,
