At North Cave Wetlands (YWT) on a hedgerow/path. A good 3" tall. I am very uncertain about the identification I've suggested.
Addendum: As noted, comments greatly received. Seemingly a bit too 'mature' to accurately identify wholly. I assume "Coprinus" is the particular family or genus therefore most appropriate to use this as the identification. Thanks to fenwickfield (who has an excellent flickr set of photos) and miked
