It does look like it! Thanks! I had no idea. The only thing that came to mind was Fontinalis Antipyretica but this is not terrestial.I'm not very good at mosses, but I would guess some kind of Plagiomnium (maybe affine?). I have had similar species do well indoors with, reasonable humidity, and they can form a nice "lawn" in a flower pot that get watered frequently.
If I had found it around here I would say so, but depending on your local moss flora it might be something closely related like Plagiomnium cf. affine - in Vitro XLWhat do you think? Is it a Plagiomnium affine or sth else?
