Collected and split with John Plischke. Growing abundantly on the undersides of Picea abies logs in a log pile. Odor not distinctive. Hymenium surface dry. Surface olive to black with 1M KOH (tested on dried basidiocarp). Odor not distinctive. Monomitic with simple-septate generative hyphae. Hymenium layered. Cystidia smooth and subulate. Cystidia measurements: (35.8) 49.4 – 58.5 (65.2) × (3.5) 4.2 – 5.3 (5.8) µm, Q = (9.1) 9.6 – 12.8 (14.4); N = 30, Me = 53.3 × 4.8 µm; Qe = 11.2. Basidia 4-sterigmate. Spores smooth, thin-walled and inamyloid. Spore measurements: (3.2) 3.9 – 4.9 (5.2) × (1.8) 2.1 – 2.6 (2.7) µm, Q = (1.3) 1.7 – 2.2 (2.3); N = 30, Me = 4.4 × 2.3 µm; Qe = 1.9.
