This medium to large bolete is commonly known as suede bolete or yellow-cracked bolete. It has a brown cap, chrome-yellow pores, and yellowish stem and grows with a wide range of hardwood and conifer trees.
Cap pale olive or tan, initially convex before flattening with a velvety tan surface, often becoming cracked in age. Flesh is white or pallid yellow, with a faint brownish zone beneath the cap cuticle; it is unchanging, thick and soft. The pore surface is yellow, becoming olive yellow with maturity and bruise blue or green before fading somewhat.
Stem is a pallid cap color, sometimes with a brick-red tinge; it is slender and slightly bulbous. The mushroom has no ring. Flesh is similarly colored as the cap but browner.
