Notes:
Growing in soil among leaf litter under Fagus grandifolius near Asimina triloba. Brown tufted rhizomorphs present at the base of the stem. Clamps absent in the pileipellis, stipe trama and lamellar trama. Stipe surface with bunches of septate hairs. Thin walled cheilocystidia present. Cheilocystidia present: 36.8 – 65 × 17.4 – 26.1 µm, Q = (2.1) 2.12 – 3.07 (3.1); N = 3, Me = 53.8 × 21 µm; Qe = 2.6. Pleurocystidia absent or rare. Brown abortive basidia present. Basidia mostly 4-sterigmate. Basidia measurements: (28.2) 30.2 – 45.4 (46.6) × (9.5) 10.1 – 12.3 (13.6) µm, Q = (2.8) 3 – 3.8 (3.9); N = 8, Me = 39.2 × 11.3 µm; Qe = 3.5. Spore measurements: (9.7) 10.5 – 12.4 (12.8) × (6.3) 6.9 – 8.1 (9.2) µm, Q = (1.2) 1.4 – 1.7 (1.8); N = 30, Me = 11.3 × 7.4 µm; Qe = 1.5
