Hymenophore composed of thin, well-developed gill folds, 2-3 mm high, densely spaced (&gt; 10/cm) but not crowded, forking, not anastomosing, often splitting transversely through their entire height, uniformly pale yellow (3A4), brighter than the pileus margin and stipe. Stipe central, up to 40 mm long, 6-11 mm wide, subcylindrical to slightly wider near the base, rapidly elongating before the pileus margin starts to spread, concolorous with the pileus margin, distinctly finely squamulose over apical portion, compact in section. Context off-white to pale cream, weakly yellowing. Odor fruity. Taste mild. Spore print off-white to very pale yellowish.</paragraph>
