Hi Deb: Eek! I'm going to guess too much water and too much humidity and darkness. Depending on the type of plant, let them dry out a bit before watering and don't put them in direct sun.

If you have mushrooms growing in with your house plants, you are maybe watering too much. You may need to re-pot the plants and give them some fresh potting soil. Hope this helps Deb.
