Firmoss

awesome photos, very helpful for future I.D's.

I don't know the species off the top of my head, but there are mosses with toothed phyllids. Toothed woodsy minium is a particularly tricky moss. Not only do its leaves have teeth, they have a distinct midrib and drip tip:

This is not to say I know what your spotting is, of course.

Hmm, you may be correct that it is not H. lucidula, that was best fit and initial reaction. I am fairly certain it is not a true moss, although you can not tell from this picture the leaves are toothed, and I do not know of any moss with toothed phyllids?

This looks different from the H. lucidula I've seen elsewhere. I wonder if this could be a true moss rather than a lycopod. The plants look too densely packed and the leaves look too thin, more like the phyllids of a real moss.
