found on young oak tree at about shoulder level
No interactions present.
there is a couple of things in there.
first, there is the liverwort Frullania dilitata growing 'appressed' to the bark, radiating outwards.
There may also be a small amount of Metzgeria furcata, another liverwort, growing as flat green 'thallose' branches to the immediate top right of the moss.
and the moss... maybe Bryum capillare because the dry-ish leaves are curling round on themselves in the characteristic 'corkscrew' manner - might be wrong here though.
