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.

Expert Response
May be agaricaceae. Definate identification is not possible from pictures. When in doubt consider them poisonous.
