In mid July this woodland had some interesting lichen on show.  Many looked like the writing lichen. Graphis. The photo above looks like Graphis scripta and the lichen with the dark fruits and rhizines, shown below, Physcia leptalea.

Thelotrema lepadinum below is an indicator species for ancient woodland. Its doughnut fruits look like acorn cups.

Warks Burn is noted for much rarer lichen mentioned in the SSSI. My walk through was brief and limited to a few quick photographs.
