Moss in my pot

I assumed this was a sphagnum moss, mainly because all my adult life I've called it that. But this morning, after taking this picture in a flower pot outside my back door, I looked up the mosses of Newfoundland and discovered there are eighty or a hundred species. Gulp. So I no longer know what it is.

Pretty though.

That's my pet Marchantia growing in the lower right.
