“Mushrooms up to 14 cm across, relatively compact, cream to ivory colored overall; cap generally darkening to a pale buff color when old or water soaked, entire mushroom becoming dark orange or rust color when very dry; hymenium of generally well-separated and long ridges, extending from the cap well down the solid stem; flesh firm, dense, cream colored, and slowly staining dull yellow when handled; odor pleasant, in fresh specimens reminiscent of apricots (contrary to Smith and Morse’s original description³); taste usually peppery when raw. Spore print white. Under the microscope: basidiospores ellipsoid, smooth, colorless, 7 to 9 × 5 to 5.5 µm; clamp connections abundant in all tissues.”¹ (footnote added).
