Moss for the Beetle Nursery

Back in May, I placed two Eastern Hercules beetle larvae in a terrarium with wood mulch substrate.

I've been meaning to top the dirt with a hairpiece of moss, but one thing has led to another, and my memory slips.  On Sunday I remembered the moss while out out in the woods, and I cut out a nice chunk of thick stuff before I packed it in for home.  It turned out I cut out a bit more moss than I needed, so I planted a flat planter with the remainder, and it will overwinter in the greenhouse where it will be a bit warmer and wetter than it is in the woods. What kind of moss is it? I have no idea, but it might be some sort of Entodon Moss.
