Last summer, I discovered this patch of brown "stuff" in my foundation landscaping, which has cypress mulch in it (although there's some bare ground showing in that area too). I am thinking it is a fungus of some kind. Do you know? Looked at closely, it seems to be an area of tightly packed "pods" with openings at the top. I got concerned about jumping worms after reading about them recently, but from what I can tell they leave behind beads of soil that look like coffee grounds -- not like this. What is this and what do I do about it? Help! Thank you.
