Hart’s-tongue Thyme-moss

This one grows on the ground, and loves shady lawns.  But the pictures below also show it under a tree at the edge of woodland, and under a tree on the bank of a burn.

It looks completely different when dry – all twisted and screwed up.  When it’s moist, it has big spreading leaves with an obvious nerve, almost translucent.

It looks a bit like a little tree, when pulled out, but not as much as some other mosses.  Close-up, you can see the teeth on the edge of the crinkled leaves, and the chunky, raised nerve.

It was one of the first mosses I identified, and in my head it will always be Plagi-omnium, not Plagio-nium as the bryologists say.

Update (Nov 2019)

I found an umbrella/tree type moss in Kiel’s Den which turned out to be Plagiomnium undulatum.  Apparently, when mature, it can take this form, branching out at the top of the stem.
