Basidiome annual to perennial, with distinctly contracted base to stipitate, corky, becoming hard corky to woody hard when dry. Pileus 4.5-8 cm, up to 0.5 cm thick at the base, dimidiate, subreniform; upper surface when young pale yellow (3A3) to light orange (5A5), becoming brownish orange (7C8) when old, strongly laccate to partly laccate, distinctly concentrically sulcate, distinctly radially rugose. Spore deposit usually pale orange; margin abruptly paler, pale yellow, slightly lobate.
