As a rule of thumb keep an eye on the caps. They are best consumed when the edges are facing down. As soon as the edges start to curl upwards they are getting ready to seed, this is where you might find little dust spores spreading around the mushrooms. Some people are okay with spores, others may have a reaction to this. Do not consume if the mushrooms have become wilted and soggy.
