Enterographa crassa

I walked from where the path left the road, west of the church, along the Poynings stream, past the dammed mill pond to the point marked by the blue pin TQ 26656 11636 |, where the spring that forms the small narrow mill pond (dammed) rises.

This posts list all the species that I saw from north to south along the path; but I only illustrate some of these with photographs

I got to Poynings from Brighton on the 17 bus, 17 Bus Route & Timetable: Brighton - Horsham | Stagecoach and got off at Newtimber, Crossways Cottages, then walked the short route along the footpath to Poynings. I tried to record all the vascular plants that I saw.

From the Poynings Road, to the bottom of the Mill Pond. The path starts at the Forge Garage, previously the village blacksmiths, I walked beside the Poynings Stream.

Huge ancient Fagus sylvatica Beech

On which there is a great deal of Enterographa crassa; a very common lichen of ancient beech in Sussex, but very under recorded as it is very small - this image is x20 magnification. A distinctive species often dominating large areas of trunk in pure mosaics of small interlocking waxy brown thalli, spotted with small dot like apothecia, which often line up in dendritic patterns. Very common in south western and Irish woodlands on humid shaded trunks. Enterographa crassa | The British Lichen Society

Upper Greensand Formation-Siltstone and sandstone. These sedimentary rocks are shallow-marine in origin. They are detrital, ranging from coarse- to fine-grained (locally with some carbonate content) forming interbedded sequences.

Zig Zag Chalk Formation-Chalk. These sedimentary rocks are shallow-marine in origin. They are biogenic and detrital, generally comprising carbonate material (coccoliths), forming distinctive beds of chalk.
