This soft egg looking object (the approx. size and apppearance of a chicken egg)was found under a rotting log. A small patch of fibrous roots resembling a tail was attached to the cover. Under the cover was a slimey substance. Inside the slime was a red object that looked like a star-fish w/ its points touching.so as to be in a ball shape. In the center of this "starfish" was something green. I live in the state of Virginia which is located on the eastern seaboard of the USA. Thank you.
