Stipe slender, 6 mm diam., 20-30 mm high, rapidly elongating while pileus is still small, paler to concolorous with pileus margin, occasionally white at base; interior distinctly fistulose. Hymenophore composed of very crowded (up to 40/cm), low but comparatively thick and blunt gill folds, these 1 mm high, repeatedly forking, frequently fissuring over their full height, yellow with brownish tint, transitioning to warm egg-yolk yellow near extreme margin. Context leathery, whitish in the pileus, almost concolorous with the stipe surface, yellowing slowly. Odor agreeable, typical. Taste mild. Spore print not obtained.</paragraph>
