Fertile head 2–2.5 mm wide, globose, differentiated from stipe. Ascomata 520–680 × 205–275 μm (x̄ = 599 × 242, n = 30), completely immersed, elongated or ampuliform, with the ostioles opening on the surface of the head. Peridium 22.8–35.0 μm (x̄ = 28.9, n = 30) wide, comprised of three layers. Asci 530–615 × 6.5–9.3 μm (x̄ = 573.3 × 7.9, n = 30), 8-spored, hyaline, cylindrical, possessing a prominent apical cap. Apical cap 3.9–4.8 μm wide (x̄ = 4.35, n = 30). Ascospores 350–465 × 1.5–2.2 μm (x̄ = 407 × 1.8, n = 60), fasciculate, thread-like, slender and long, breaking into secondary ascospores when mature. Secondary ascospores 6.7–9.4 × 1.5–2.3 μm (x̄ = 8.1 × 1.9, n = 60), hyaline, cylindrical. Asexual morph: Undetermined. (Adopted from Wen et al. 2016)
