Question
I found a whole lot of these mushrooms under some pine trees on the northern sides in Kansas City and wonder if they are safe to eat.

Answer
In general IF you are not sure do not eat them. Here is a web link that will give you information about mushrooms and which can be eaten. http://mdc.mo.gov/nathis/mushrooms/mushroom/index.htm

It start out with general information then has a section on edible and poisonous mushrooms. More than likely yours are not to be eaten.
