Stereum atrorubrum is the only local fungus I have found with a description matching this weird crust. This species has only been described from a single specimen in upper Cascadia, so I haven't been able to find images to compare it to.
"Elfin Saddle" with brown cap and smooth white stipe. Scattered throughout Douglas fir needle duff. 5 to 8 cm tall. Mycoflora # 62038
