Title: Need to identify a fungus in a flower garden in Lansinging, MI.
Answered by: Jimmy Mills


I have a fungus in my flower garden. It is white and ground hugging. It is in a moist area under a large spruce where mulch has been laid down. When I step on it , it expels a green dust. What is it and how do I get rid of it? Thank you Pete


What you are describing is very typical of many  fungi. They grow in shaded, moist areas with organic matter to provide food. The green dust you mention is a cloud of spores that disseminate the fungus. However, nothing in your description gives Mr. Smarty Plants a clue as to the identity of the fungus in question.

I suggest the you contact the folks at the Ingham County Office of Michigan State University Extension who can provide a mycologist or gardener who can identify the fungus you are describing, and offer suggestions for combating it.
