|Myxocarps gregarious or scattered, sessile on a narrow base, ▒ terete, sporocarps 0.5-1 mm diam., 1 mm high, plasmodiocarps 1 mm diam., up to 12 mm long and often branching and occasionally reticulate or annular, mustard to pale yellow brown. Hypothallus reddish brown, membranous, inconspicuous. Peridium of three layers, the outermost layer pigmented, smooth, occasionally with dark brown varnished spots or bands, the middle layer of densely packed lime, the two outermost layers fused, but not adherent to the innermost layer, the inner layer thin, membranous, transparent, iridescent, the two outermost layers usually remaining intact at maturity, occasionally fracturing into large, irregular, non-reflexing platelets. Dehiscence of the inner layer irregular. Columella absent. Capillitium of numerous angular lime knots up to 100 Ám long, connected with lime-filled or hyaline tubules, badhamioid, sometimes with a white to cream pseudocolumella. Spore-mass nearly black.
