a tripod that can’t be used around big trees or rocks… did you buy a tripod or a three-legged agoraphobe? a tripod with nature deficit disorder is not a tripod you want to be using for mushroom photography.
look at this picture. i can see big rocks, trees and a tripod.
and this one’s even in water, plus big rocks.
I suggest either getting your tripod some therapy, or finding one that shares more of your goals in life.
