Plasmodium colourless. Hypothallus thin, delicate. Sporocarps on a constricted base, rarely short-stalked, varying to flat-pulvinate, annulate or plasmodiocarpous, sometimes widely expanded, crustose, pitted, white, or dingy grey to dark metallic when lime is scanty, the sporocarpous forms 0.2-0.5 mm wide. Peridium membranous, colourless or purplish-brown, iridescent, covered with a rather sparse layer of lime crystals, occasionally limeless. Dehiscence circumscissile or by a ± elongate split. Columella absent or represented by an ochraceous or brownish deposit at the base of the sporotheca. Capillitium abundant, of freely branched and anastomosed, slender, dark threads forming a somewhat elastic net. Spore-mass dark brown. Spores violaceous-brown, verruculose, the warts sometimes clustered, (7.5-)8-10(-11) µm diam.
