mushrooms invading indoor vegetable garden #927225

Asked March 31, 2026, 9:21 PM EDT

These mushrooms are very persistently growing in my indoor gardening tower, which is filled with commercial potting soil from two well-known brands, and planted with a variety of vegetables. The mushrooms grow from baby to full size in about a day, and if I miss removing them, they fully open in about one more day. Their spores are a bright yellow/gold dust. What kind of mushrooms are these? And are they poisonous? Thank you.
