Basidiomata small to medium, with the stipe equal to or somewhat longer than pileus diameter. Pileus 22–30(–70) mm diam, convex, sometimes depressed in the center. Surface velutinous, not fibrillose, ochre with pale orange tints, especially in the centre, nearly white at the margin in young basidiomata. Stipe 20–35 × 5–8 mm, cylindrical or with a slightly broader base, white to very pale ochre, slightly darker ochre when bruised. Staining often ochre when handled. Spines usually decurrent, crowded, conical, acute, white to pale ochre. Odour weak, fruity, citric-like; taste mild, slightly bitter-acrid afterwards. Macrochemical reactions not tested. Basidiospores 7.5–8.5(9) X (5.5)6–7 μm (Lm =8.2–9.1; Wm = 6.4–6.6; Qm = 1.28–1.35), ovoid to broadly ellipsoid, thin-walled. Basidia 3- to 5-spored, 45–50 × 7–8 µm. Hyphae of the apex of the spines cylindrical, thin-walled, with clavate to cylindrical ends 3–4.5 μm diam. Clamps present at all septa.
