I found 6 little grey mushrooms in my yard April 22, I find them there just about every year. Hornharvester said if you want to have some fun, put a gallon glass jar over the mushroom and watch it. I had never done this before so I tried it. It is close to my back porch, so I watched it every day. I dumped a gallon of rain water over it every 3rd day. I was impressed.

Day 1-mushroom was 1/2 inch tall


Day 13-It's growing


Day 16-I didn't think it would get any bigger


Day 19-I was impressed, the other 5 mushrooms got bigger, but not as big as this one.


Day 20-May 11 The taste test on a bread and butter sandwich. Awesome! It was fun to watch it grow.
