Cap:
flat on wood with pore surface exposed, becoming widely spread out, usually tightly attached, sterile margin usually rather wide, thinning out
Flesh:
subiculum thin, soft; white to cream
Pores:
3-5 per mm, "rose-pink to cream, usually drying cream to pinkish-buff"; tubes originating as isolated depressions and then uniting
