　Description： Mycelium superficial, consisting of narrower brown hyphae, 3-4 μm wide, and wider dark brown hyphae, 6-8 μm wide, forming a sparse subiculum with hyphae penetrating into and mingled with host tissues. Mammaria anamorph abundant on subiculum. Ascomata globose or ovoid, 390-490 μm wide, 330-500 μm high, loosely gregarious, erumpent through the host tissue and then appearing superficial, rough, rounded on top, ostiolate, sulcate with age, lined with flexuous, 2-3 μm wide periphyses. Peridium seen as areolate and angular patches separated by light lines on the surface, 26-46 μm thick, 2-layered, the inner layer 10-14 μm wide, composed of elongated, thin-walled, hyaline cells, the outer layer 16-36 μm wide, composed of polygonal, thick-walled, blackened cells, externally covered with one layer of textura angularis which is up to 20 μm thick and composed of yellowish to brown, polygonal cells and sometimes reduced except around the base of ascoma. The basal portion of outer wall with hyphae identical to narrower hyphae in the subiculum. Asci cylindrical, 80-110 × 8-10 μm in the ascospore bearing portion with truncate at apex, unitunicate, 8-spored, basal, stipitate, stalk 30-45 μm long, with a refractive, nonamyloid apical ring. Paraphyses 2-3 μm wide. Ascospores biseriate to partially uniseriate, hyaline, elliptical, 17-22 × 5-6 μm, curved in the lower third, occasionally narrower towards the base, 1-celled, rarely 1-septate near the middle, becoming pale brown and up to 3-septate when germinating.
