Hello, I found a mushroom growing in a pile of rotting wood chips
under an evergreen shrub in Seattle, Wa. I was hoping someone could
tell me what this critter is, exactly!  Ahem....The domed cap is dark
orange, approx. the size of  half a grapefruit and covered in raised,
off-white  markings;   the stem is white and smooth. The specimen I
found is 15 cm in length. Here is a link to the photo I took:

Thanks for your time, Steve Z.
