This is an small and unique white birch branch with an attached polypore/conk. It is about 4 inches long and approximately 2 inches wide by 1.5 inches thick. It would make a great apartment for any tarantula or a piece of furniture for a python, gecko or other critter in your vivarium. This piece can also be used in a floral arrangement, koi pond, terrarium, paludarium, museum, garden, wedding, or piece of art. It was found in my woods in North Central Wisconsin.
