Description: — Spore-sac subglobose, 9 mm wide, 7 mm tall. Exoperidium indistinct, incrusting sand, remaining as a cup-like structure at the base of the spore-sac. Endoperidium thin, smooth, slightly creamy-brownish to grayish white. Mouth oval, indistinct. Socket inconspicuous. Stem slender, 2 – 3.5 mm wide, 30 – 35 mm tall, slightly creamy-brownish to grayish white, somewhat longitudinally furrowed to fissured and appressed scaly closer to the spore-sac, with a small basal mycelial bulb. Mature gleba orange brown. Capillitial threads (1.6) 3.5 – 4 (6.3) µm wide, hyaline, undulating, irregular thickness, thick-walled, with uneven inner walls, ramified. Septa rare, slightly widened up to strongly widened. Spores subglobose, regularly verrucose, 5.6 – 8.5 × 6.6 – 9.2 μm without ornamentation, 6.2 – 9.8 × 6.8 – 10.6 μm including warts. Warts are large, 6 – 7 on visible side of spore, 0.5 – 0.6 μm wide, 0.8 – 0.9 μm length, more or less isolated or merging into groups with small warts or forming ridge-like anastomoses at the base, visible on SEM.
