Dog Vomit Slime Mold is actually beneficial to breaking down organic matter in the soil. It is common to see on wood chip or bark top mulch. I had it around my hydrangeas when I had the bright idea to use wood chip mulch. I hate wood chip or bark mulch because it attracts grubs, slugs, and mold. The combination of bark, and Dog Vomit Slime Mold, is a condition I call Barf.Well, this was a new one on me. I went out to check on stuff this morning and noticed a creepy sponge-like growth on a couple of my cucumber plants. It was wrapped totally around the stems and when I dug at it with a stick it smelled like mushrooms. I cleaned it all off my plants and hosed them down, then came inside to research.
Apparently this is called "Dog Vomit Slime Mold"![]()
and is quite common, though I have never seen it before... at least in my garden.

Of course the recommendation is to NOT hose it down because that will spread the spores but too late now.
It is important to distinguish the difference in Dog Vomit Slime Mold and Dog Sick Slime Mold. The sick one is found in lawns where overwatering during cool spells, brings this mold to full glory. It isn't so much an organic decomposing mold like the vomit variety. Either mold may be white or yellow adding to confusion in identifying.
