Devonian plant that needs an ID

We are about to leave in a few minutes (from lake Wallenpaupack where we currently are) , but before we left we helped a neighbor (who was absent) reposition a dock for when they let out water from the dam. He had used rocks from the location of the house as a border for a walkway, and I found this obvious fossil. It's Devonian, Catskills formation shohola member. I found a few other worse ones. First fossils I know of from Lake Wallenpaupack. Any ideas on what type of plant?

Could it be colpodexylon?

The leaf cushions are quite different for Lepidodendropsis.  Instead, it looks like a good match with: Colpodexylon deatsii

Banks, H.P. (1944).
