Sporocarps closely gregarious, stipitate, total height 1.25-1.75 mm. Sporothecae hemispherical to subdiscoid, brown, 0.5-1 mm diam. Hypothallus membranous, pale brown, discoid. Stalk c. 66% of the total height, rugose, flared at the base, pale brown, translucent, merging into the sporotheca base, which is marked by radiating, fine, brown lines. Peridium triple, the outer layer smooth, glossy brown and cartilaginous, the middle layer white, calcareous, the inner layer membranous and inconspicuous. Dehiscence apical, irregular to floriform. Columella represented by a flat, thickened, rugulose, whitish to pale flesh-coloured sporotheca base. Capillitium reticulate, attached to peridium and columella, the threads slender, branched and anastomosed, pallid under the lens, brown with slightly paler extremities by TL, with occasional small membranes in the junctions. Spore-mass dark brown. Spores dark brown (some with a slightly paler area), ▒ globose but lenticular when dry, c. 12-13 Ám diam., densely and uniformly warted.
