Shaggy Ink Cap

I had a great night camping at Kilinallan where, as usual, the flora is just breathtakingly beautiful. However, I seem to be fixated on the arguably less beautiful at the moment (what with the last 'slime mould' entry) and was quite taken by this specimen of Shaggy Ink Cap, growing from a cow pat. I'm not 100% sure of the ID so am open to other suggestions.
