This was found overly mature, the center of the cap was sunken, the stalk was seeming rotted, and when I broke off the fruiting body there was a LOT of water (you can see droplets on the mushroom in one of the pictures). It smelled absolutely horrible, very acrid, and left the stench all over my hands. It was found growing out of soil out of which some trees were growing a few feet away, but I do not know what species of tree it was, a typical Florida tree, spanish moss and all.
