Slime Mold
The frequent rain has created an explosion of slime mold in the bark beds lately. While it may look like your dog was sick or your crazy uncle drank too much, it is a fungus. It is not toxic. It can be yellow, gray, black, or other colors. You don’t have to spray it with anything. Grab a shovel, dig it up, and throw it away. This is more common in beds that had fresh bark this spring.
