Description: | Mycelium superficial to partly innate in substrate, composed of thick-walled, dark brown hyphae, 5-8 μm wide forming a dense subiculum in which the ascomata are embeded. Ascomata globose to subglobose, 290-390 μm high, 250-330 μm wide, gregarious, slightly rugose, covered with numerous hyphae with a broadly conical ostiolar region, 250-330 μm high, lined on the inside with periphyses. Peridium of two regions, the outer 30-44 μm thick, composed of brown, thick-walled cells, forming a textura angularis to epidermoidea, inner layer of peridium variable in thickness, widest at the basal portion, 8-20 μm wide, and becoming narrower towards the lateral sides. Asci bitunicate, basal and peripheral, cylindrical, 110-140 × 10-14 m, shortly stipitate, 8-sporede. Ascospores 30-43 × 5-7 μm, fusiform, overlapping biseriate, 3-5 septate, slightly constricted, overlapping biseriate, slightly constricted at septa, at first hyaline and then becoming brown, with mulcilaginous sheath. | |||
