From a search cross reference I think it is different, but there is nothing too concrete. Some sites list it as the same, some list it as different.
Xmas Moss <<
This Willow Moss is NOT what I have.
Virgil you will most likely be able to find some choice pieces near a river mouth on the beach. Wood which washes up as driftwood is washed clean in the salt water and bleached under the sun *usually*. It will just need to be weighted down which you can do by putting rocks on it in the tank, or putting rounded rocks in a nylon stocking and tying to the wood. This is what I did in the beginning for some of my driftwood from the beach. Just hid the black stocking with a plant.
