Sphagnum ID

Wow what an amazing day to be a bryologist in the space of 20 feet I foundwild Marchantia polymorpha (it's a different subspecies from the green house weed), Plagiochila porelloides (It's huge!) Riccardia multifida (in my petri dish) and Hookeria lucens moss and I was able to ID all of them in just about an hour.

 Earlier this week with help from exeperts I identified Spagnum girgensohnii and I  then I identified Sphagnum squarrosum all by myself. I am starting to understand the Sphagnum keys but still no luck getting a branch leaf cross section.

Riccardia multifida with up to 3 unistrose border cells and oil bodies only in the internal tissues

Hookeria lucens at just 40 times, the cells are huge

Plagiochila prelloides, this plant is huge for a leafy liverwort

Cepahlozia bicuspidata subsp lammersiana

Lophozia sudetica?

This keyed out to sudetica, the only problems is this was on wood and sudetica is listed as growing on rock. The more keys I look at the more confused I get.
Leaves are slightly less than 1mm long and wide they are bilobed. If there are underleaves I don't see them, but that does not rule out under leaves.
Very clear trigones. 4-6 oil bodies in 30um angular cells.

The sparse geamme are cone shaped and quite unusual.
I did not see microcellous areas in my sloppy and way too thick stem cross sections.
