I had given my Red Luna Peperomia a really good dousing a couple of days ago, and to my surprise, these popped up for the first time yesterday!
The shroomery.com forums told me it was a Pluteus mushroom, and after some research, I think it might be a Pluteus flavofuligineus. Non-toxic, fairly innocuous, usually grows on dead wood so I'm not sure what it's doing in my indoor container garden, but hey.
I used Miracle-Gro Organic potting soil to pot the peperomias. Since the only access to the outdoors these pots have is through the windows, and the peperomia is set pretty far back on the table, I suspect that the potting soil may be where the spores came in from.
Mushrooms in the garden are a totally new experience to me. Will they stunt the growth of my plants? Help them? Not affect them at all? Should I dig down and remove the body of the mushroom if I want to protect my peperomias?
Thank you so much for your thoughts!
