Description:
Stromata multiple, clavate, pale yellow, arising from head, thorax and abdomen of Tenebrionidae larvae (Coleoptera), 2–10 mm long. Stipes cylindrical, smooth, pale yellow, 0.5–1.5 mm wide. Ascomata formed on upper part of the stipe, or subterminal, occasionally located on one side of the stipe, pale yellow, densely packed perithecia, 2–4 mm long, 1.5–2 mm wide. Perithecia immersed, tightly packed, broad ovoid, 400–500 × 250–350 μm. Asci cylindrical, 200–300 μm long, 6–8 μm wide with asci caps 3.5–7 × 3.5–8 μm.
