Notes:
Growing on the underside of a Prunus serotina stick with Xenasmatella vaga, Tulasnella violea and Everhartia lignatilis. Sparse, whitish subiculum present. Hairs hyaline, cylindrical, thin-walled, septate and smooth over much of their length with basal incrustation. Ectal excipulum of textura angularis. Paraphyses filiform and branched with swollen tips. Asci unitunicate, inoperculate, 8-spored with amyloid apical plugs. Spores smooth, hyaline and mostly 1-septate. At least 1 spore was 2-septate. Spore measurements: (7.9) 9.1 – 10.8 (13) × (2.6) 2.7 – 3.6 (4) µm, Q = (2.6) 2.7 – 3.8 (4.6); N = 30, Me = 10 × 3.1 µm; Qe = 3.3
