Hello we have this HUGE mushroom(s) growing in our driveway. It grew incredibly fast.....noticeable size difference after a few hours. Any ideas what this is?
Hello. Though I am not an expert, these look like they could be something in the Amanita or Agaricus families. Without a photo of the stalk and gills, it will be very difficult to make a more specific ID. Many mushrooms are very fast-growing. I have some baeosporas in my yard that come up, grow, mature, and then wilt back all between the hours of 5 AM and 7 AM. You can literally watch them grow! If you can get some pics of the bottom parts of these guys, we can narrow it down. Mushroom ID can be really tough, as so many different species can look so similar.
