Looks a bit like a common ink cap coprinus atramentarius but could be vareity of diifferant fungi from the same family such a psathyrella. When the cap has got very wet there is often a feature on the stem that defines it, such as a ring like thickening or brown scales. It may of turned to black mush by now though it may of also opened flat both of which will tell you more about what it could be. Not much help I am
