An uncommon to rare small to medium bolete, always found on the Common Earthball, Scleroderma citrinum; now believed not to parasitize living earthballs so much as feed on already decaying ones. The earthballs in this picture, however, look in pretty decent condition to me. Always a pleasure to come across this piggyback bolete, which may occur under a variety of trees, but always on the Common Earthball. It has been recorded on 5 sites in Notts.
