Sporangiate D. squamulosum with loose, powdery lime layer.
Sessile and stalked sporangia with plicate lime layer.
Sporocarps sessile or short stalked sporangia, the stalks white, furrowed, supported on small white, circular hypothalli. Stalks, when present, up to 0.4 mm tall by 0.1 mm ∅ . Columella white, domed, filled with lime. Sporangia apparently spherical or pulvinate but actually deeply umbilicate below; to 0.8 mm ∅. Peridium encrusted with stellate lime crystals, either as a loose powdery layer, or as smooth folded plates. In the absence of lime the peridium may appear transparent or faintly iridescent.

Capillitium consisting of fine dark or hyaline threads, usually straight but sometimes with occasional spiral twists, with occasional swellings.
