Growing on a Pinus strobus log. Associated with a brown rot. Drying to a dingy yellow. Odor not distinctive. Releasing brownish oil droplets in Melzer’s reagent. Monomitic with clamped generative hyphae. Subicular hyphae brown. Hymenial hyphae hyaline. Cystidia hyphoid and abundant, leptocystidia. Basidia 4-sterigmate. Spores strongly amyloid, smooth and thin-walled, many sticking together in clusters of 2 to 4. Spore measurements: (5.3) 5.5 – 7.3 (7.9) × (1.9) 2 – 2.7 (2.9) µm, Q = (2.2) 2.3 – 3.4 (3.9); N = 30, Me = 6.3 × 2.3 µm; Qe = 2.8
