Cardboard probably sets up the ideal combination of moisture retention, shade, etc. to kick-start the fruiting. The only other thing I can add to the discussion of fungi is that edible varieties inevitably prefer hardwoods. My abundance of fir deadfall chips up into great mulch, but doesn't foster the tasty 'shrooms. :(
