While raking up a trailer load of  well rotted oak leaf compost I discovered  these small dark potato like tubers. They were under a 100+ year old oak tree in Ruffy  township. When broken open they contain grainy black rubbery stuff that has a strong mushroom earthy aroma. I have never smelt or tasted  truffles so be not sure what to expect. Tasted a few raw slithers with no ill effect ( as yet ). They have a pleasant enough taste but nothing to rave about. Might look up some truffle recipes to truely test their flavour. Does anyone have experience of wild truffles? Do these look like the real truffles? Have I posioned myself ?
