I too think this is quite unusual a place to find mushrooms as we have them- or the field mushrooms as it suggest in fields ! grow in damp wooded areas , But an interesting area to visit I am sure !
I know it has to be moist for mushrooms to grow, but in this picture the grasses look like they could be growing on the African plains. I guess it's the dead tree that makes my imagination wander in that direction! Nice shot.
