Overview
Plasmodiocarps white or cinereous, laterally compressed, branched and anastomosed to form an intricate net, with occasional simple plasmodiocarps or sporocarps interspersed, 0.2-0.4 mm wide. Hypothallus broadly expanded but colourless and inconspicuous. Peridium membranous, fragile, translucent, iridescent, sparsely to densely powdered with white lime crystals, these sometimes aggregated into small, discoid platelets, rarely limeless. Columella conspicuous, wall-like, elongated, extending longitudinally nearly the full length of the plasmodiocarp, attached to the base by broad extensions, free above. Capillitium dense, with few anastomoses, the threads slender, brownish and 2 µm diam. below, hyaline and more slender at the tips. Spore-mass black. Spores dark brown, sparsely and irregularly spiny or subreticulate, ( 10-)11-13 µm diam., interspersed with numerous vesicular bodies coloured like the spores but paler, larger and more irregular in shape. Plasmodium probably white.
