Notes:
Resupinate. Growing on a corticate Fagus grandifolia log. All structures inamyloid. Seemingly monomitic with abundant clamped generative hyphae with many branches. Some hyphae lightly encrusted and some with inflated hyphal tips. Spores smooth. Spore measurements from Piximetre: 3.8) 3.9 – 4.6 (4.7) × (2.6) 2.7 – 3.3 (3.4) µm, Q = (1.2) 1.3 – 1.5; N = 12, Me = 4.2 × 3.1 µm; Qe = 1.4
Individual spores: 4.08 × 3.26 µm, 4.17 × 3.45 µm, 3.90 × 2.94 µm, 4.75 × 3.24 µm, 3.75 × 2.76 µm, 4.32 × 3.13 µm, 3.88 × 2.57 µm, 4.59 × 3.25 µm, 4.47 × 3.24 µm, 4.42 × 3.00 µm, 4.14 × 2.70 µm, 4.28 × 3.24 µm
