The Mushroom

I believe that I have identified the mushroom I wrote about in my previous blog. Here is the photo again:



I believe it is a Lycoperdon Marginatum. It is supposedly edible when young though you won't catch me eating one because how would I know if it's young or not? And what if I am wrong in my identification? It is supposed to have some "psycoactive characteristics". It is described as a puffball mushroom. This photo illustrates young and old (I suppose).
