Growing among duff and bark under a fallen conifer. Pinus ponderosa, Pseudotsuga menziesii var. glauca, Picea engelmannii and Abies concolor nearby. Asci unitunicate, operculate, thin-walled, with amyloid apices and 8 uniseriate spores. Spores hyaline and smooth and without guttules. Spore measurements: (12.7) 13.6 – 15.2 (15.4) × (7.7) 8.2 – 9.2 (9.6) µm, Q = (1.3) 1.6 – 1.8 (1.9); N = 30, Me = 14.3 × 8.6 µm; Qe = 1.7
