I have started seedlings in my south window of my home. They were started in the jiffy greenhouses, and I've moved them to newspaper pots. When I checked on the seedlings this morning, I found mushrooms growing in the flat! I know mushrooms are fungi, but how do I get rid of them? Are they going to bother the seedlings? My main concern is that they may be poisonous, I have a four year old and cat in the house. I've started seedlings this way for years, and have never come across this. The other weird thing is that they're only on the pots with the cosmos, not the zinnias, and they're in the same flat (don't know why that would make a difference?) Any advice you can give is appreciated.
