Disciseda candida is a small, puffball-like gastromycete with a white to cream-colored, flattened spherical fruiting body that detaches from its underground base at maturity. It inhabits dry calcareous and sandy soils in steppe and dry grassland environments in central and eastern Europe. This saprotrophic fungus decomposes organic matter in arid grassland soils and disperses spores when its papery peridium splits.
