Growing on Big leaf maple tree, and seeing it more and more often on growing on trees in the area. I didn't know until going to Pack forest that this plant is an epiphyte, which explains why I always see it growing on other trees unlike sword and lady ferns which stem from the ground. Other plants surrounding the tree and licorice fern were red huckleberry, sword fern, and snowberry. Growing often in the same places as moss on trees.
