 Fruiting body a sessile sporangium (or occasionally somewhat subplasmodiocarpous), scattered, round-pulvinate to elongated, at first chestnut or pale brown, becoming blackish brown with age, smooth or wrinkled, 0.1–0.9 mm long and 0.1–0.4 mm wide. Peridium somewhat cartilaginous, nearly colourless or pale brown, often overlaid by a more or less continuous layer of dark granules, dehiscence along definite preformed sutures forming plates or stellate lobes whose margins are often marked with a row of minute warts about 1 µm in diameter. Spores pallid to brown in mass, pale yellow to pale brown by transmitted light, smooth or nearly so, paler on one side where the walls are thinner, 9–11 µm in diameter. Plasmodium hyaline, then brown
