Recognized by sight: Cap is not the right color for Psilocybe cyanescens, nor the right shape. The pin is too round and not caramel enough for P. cyanescens. Looks like Psathyrella. Not sure what to think about the blue staining, was it really getting darker blue as it get damaged? Looks like it was sprayed with weed killer that had green dye? Or maybe someone drew on it with a blue sharpie.
Based on microscopic features: Dark brown ellipsoid spores with a germ pore
