I am wondering about these fungi that have popped up in my garden a couple of weeks ago. Basically in a shady woodland area of the garden, but literally covering everywhere. The brown one seems to be popping up in more open areas, and in my pots!! See the size of them growing in a 4" pot. The tinier white mushrooms only appear underneath the Blue Spruce. What kind of mushrooms are they - native or not? Are they bad for the soil? Should I be squishing them out of the pots? Thanks for any and all help.
