Notes:
Growing on the underside of a Pinus bungeana cone and the needles underneath under ir. Presumably mycorrhizal with Pinus bungeana. Dimitic with skeletal brownish skeletal hyphae and clamped generative hyphae. Subhymenial hyphae brownish to yellowish and not becoming blue-green in 1M KOH. Subhymenial hyphae hyaline and becoing blue-green in 1M KOH. Basidia 4-sterigmate and blue green in 1M KOH and blue-green pigment leaching out. Young basidia sphaeropedunculate. Spores brown and warted. Spore measurements from Piximetre: (5.5) 5.9 – 7.1 (8.5) × (5.1) 5.3 – 7 (7.6) µm, Q = 1 – 1.1 (1.3); N = 30, Me = 6.5 × 6.2 µm; Qe = 1.1
Individual spores: 6.70 × 6.38 µm, 6.42 × 6.38 µm, 7.06 × 6.98 µm, 6.71 × 6.59 µm, 6.25 × 6.04 µm, 6.34 × 6.12 µm, 6.82 × 6.76 µm, 6.50 × 6.38 µm, 6.19 × 5.92 µm, 6.26 × 5.81 µm, 5.91 × 5.53 µm, 7.67 × 7.62 µm, 6.75 × 6.11 µm, 6.69 × 6.33 µm, 6.19 × 6.01 µm, 7.64 × 7.56 µm, 7.01 × 6.28 µm, 5.85 × 5.31 µm, 5.72 × 5.41 µm, 6.19 × 6.18 µm, 5.64 × 5.45 µm, 6.10 × 6.08 µm, 7.02 × 6.31 µm, 6.05 × 5.88 µm, 5.49 × 5.11 µm, 6.61 × 5.19 µm, 6.32 × 6.15 µm, 8.46 × 7.58 µm, 6.25 × 5.14 µm, 6.53 × 6.26 µm
