That Looks Like. . That Looks Like. . Forget the table scraps. It's probably slime mold, a brightly colored fungus that spreads across wood mulches during periods when temperatures are warm and humidity is high.
Most people report seeing an area in mulched beds that appears as though someone has vomited.
Although this can be disturbing to most Gardeners, it's no cause for alarm. Slime molds in the genus Fuligo are fungi that can appear bright yellow to orange, fading to brown and tan as they dry. They pose no threat to plants, animals or children, but they look awful and might be distracting at a Garden tour or barbecue. You won't find any miracle cures for slime molds because chemicals do not kill nor eliminate the fungi. The best approach to controlling these unique organisms is to try changing the environment in which they grow.
