Peridium membranous, covered with various amounts of white, stellate, or sometimes less regular, lime crystals. Columella absent. Capillitium consisting of slender, yellow-brown threads attached to conspicuous, subglobose vesicles, these 30–50 µm in diameter, filled with yellow granular material. Spores brown in mass, pale violet-brown by transmitted light, minutely warted, 8–11 µm in diameter. Plasmodium yellow.[
