This Mushroom Geocache is a great little geocache that hides in plain sight.  A resin mushroom top with a screw lid container.  Push into the ground, into a hole at the bottom of a tree, or you could even fix it to a post and watch the comments from finders and the dnf's.  Now comes with a RITR Log and small pencil.

The mushroom head measures approximately 5.5cm x 3cm and the container is 15ml measuring approximately 10.5cm x 1.4cm
