Polypore Dereliction

I took a quick walk around Black Hill, Bagshot after shopping today, primarily on a vague hope of some fungi after the recent rain,  not that I have ever seen many here and today was no exception.  However, I did find this broken off polypore lying on a concrete wall (the site is or was used by the MOD) which meant it was easy to photograph the underside with its interesting pores, now in a state of decay - so one for Derelict Sunday methinks!
