Yellow Vomit-Like Thing Could Be Mushroom Related

Q. I found this thing in the picture I sent to you under my Joshua tree this morning. It is about 6 inches long?  Is it mold?  I only water three times a week for 5 minutes

A. I get a picture of this once a twice a year, usually in the spring when it is cooler, there has been rain and there is plenty of wood chips for it to feed on. This is called a slime mold. Kind of resembles vomit.

They can range in colors from yellow to orange and are related to mushrooms in a very loose sense. Like mushrooms they are a decomposer and feed off of decaying organic matter like wood mulches or undecomposed organic matter in the soil. We see them in the orchard a lot feeding off of decaying wood mulch.

No treatment is necessary. It is a good guy since it breaks down woody debris. Does not attack living plants. If you want to be an industrialist, destroy it with the back of a rake and rake it into the mulch and soil. It will probably come back at some time but like a pest would but it is a pest only because we are afraid of it. I will post pictures of some on my blog.
