This mushroom resembles a small pancake! Cap diameter is greater than an inch. The spongy pores (seen in third photo) and thick stalk are cream colored. Cap appears to have some kind of white residue on the cap where it was damaged.
Seen growing on the floor on the outskirts of an alpine forest, among moss, in the northeast part of the Kenai peninsula. Elevation was around 3000', just footsteps away from Kenai Lake.
