For those of you who do not have access to Facebook, here is a glimpse of some yellow parasol mushrooms (also known as flower pot parasols) growing in one of our indoor pots. They are common inside when it’s humid out, and they are poisonous if eaten. As much as I hate mushrooms, these were really interesting to watch – you could see growth by the hour. They grew to about 4 inches in height. The entire phase happened over the course of about three days!
