Mushroom Log

So many of the decaying logs at Habitat Home have this fungus growing on them this fall. It is classified as a puffball and Lycoperdon pyriforme is its name. One reference book says it is "presumed edible" and another source says "edible". However, I do not think I will try cooking any but rather choose to enjoy their unique forms on the old logs. I did notice after a closer examination of the fruiting bodies that something has been nibbling on them, perhaps mice or squirrels?
