Looks brownish/cream in the photos but looked more blackish/cream in real life.
No sign of web: found on wooden facings of a nature hide. hopefully details are attached to the photo.
Only one I could find close was a False Widow spider but this was a small chap.
Didn't have my macro lens with me so pics not as good as they might have been: hopefully still enough to aid ID.
Thanks in anticipation !
UPDATE: 13/9/17 actually I think one of my friends ID's it as a Walnut Orbweb Spider (Nuctenea umbratica)
