Description:PILEUS 40–165(240) mm diam., infundibuliform; margin strongly involute when young; surface dry, matted tomentose at first, eventually fibrillose to squamulose at disc, with cottony roll of tissue at margin when young, later appressed fibrillose to tomentose, cream or pale orange (4A2–4A5, 5A3) at first, then browner near brownish orange (6C6) at disc and paler (whitish) towards the margin. STIPE 30–90 x 11–35 mm, cylindrical, sometimes curved; surface white, staining brownish (4A3–4) where injured, dry, tomentose to pubescent. LAMELLAE adnate to subdecurrent to decurrent, up to 6 mm wide, subdistant, occasionally forking, white to cream (4A2–3); edge entire and concolourous. CONTEXT firm, white, unchanging when cut; smell fruity and cheesy; taste very acrid. LATEX scarce to abundant, white, staining tissues pinkish to eventually brownish; taste very acrid. CHEMICAL REACTIONS: context green blue with guaiac, orange with FeSO4; cap surface reddish cinnamon with KOH. BASIDIOSPORES broadly ellipsoid to ellipsoid, 8.1–9.6–10.4–11.3 × 6.7–7.4–8.5–9.5 µm (Q= 1.15–1.21–1.32–1.47); ornamentation up to 1.5 µm high, consisting of isolated conical warts, sometimes connected by very faint and fine lines; plage inamyloid, rarely centrally amyloid. BASIDIA 45.5–63.5–81.5(83) × 10–13–16 µm, subclavate, 4-spored. PLEUROMACROCYSTIDIA (45)46–70.5–95.5(103) × (4)4.5–6.5–9(10) µm, abundant, cylindrical with tapering and fusiform apex, thin-walled. PLEUROPSEUDOCYSTIDIA 2.5–7 µm diam., not to slightly emergent. STERILE ELEMENTS 37–49–62(64) × 3–5–7 µm, cylindrical, septate, with rounded apex. LAMELLAR EDGE sterile; marginal cells 13–23.5–34 × (5)5.5–9.5–13(13.5) µm, cylindrical to clavate, sometimes septate. HYMENOPHORAL TRAMA mixed, with hyphae, lactifers and sphaerocytes.
