Marginal hyphae on sterile surfaces of basidiocarps cylindrical, simple or branched, smooth or roughened, straight or flexuous, septate, thick-walled, hyaline, 3.0–8.5 µm in diameter. Internal hyphae branched, septate, thin-walled, hyaline, smooth or roughened, 2.3–11.0 µm in diameter. Hymenium limited to the upper surface of the basidoma, amphigenous, composed of basidia and simple cylindrical hyphidia; hyphidia hyaline or pale yellow, smooth, thin-walled. Subhymenial hyphae, smooth or roughened, thin- to thick-walled, 2.5–5.3 µm in diameter. Basidia cylindrical to clavate, smooth or roughened, pale yellow, thin-walled, becoming bifurcate, (30.0 –) 38.5–79.5 (– 83.5) × (5.5 –) 6.5–10.6 (– 11.1) µm, L +m += 60.2 µm, W +m += 8.3 µm. Basidiospores [95 / 5 / 1], broadly and elliptic-fusiform, with a small apiculum at the base, thin-walled, pale yellow, with oil drops when young, (16.5 –) 18.5–28.5 (– 29.5) × (8.7 –) 8.9–13.8 (– 14.6) µm, L +m += 23.9 µm, W +m += 11.0 µm, Q = (1.5 –) 1.8–2.4 (– 2.5), Q +m += 2.2, usually 7 – septate, rarely 3 – or 4 – septate at maturity. Germination not observed.
