Here's a classic autumnal scene. Crisp leaves and the cases of Beech nuts littering a woodland floor - or even a pavement. I think you can even see a beech nut or two, as well as the empty burred cases, especially in the top left area of the picture. However if you really want to know what they look like, here are some great pictures and advice on eating them from Raw Rob's blog on wild food. Apparently they were used as a coffee substitute during the war!
