Spore sac 1.5–5cm across, minutely roughened, opening by several pores to resemble a pepper-pot, supported by several slender columns; silvery-brown. Spores 4–6ΒΌ in diameter, globose, irregularly warted. Spore mass brown. Habitat in sandy soil in fields or wood edges; late summer to autumn. Found regularly in the Channel Islands, but apparently extinct in mainland Britain, extinct on Red Data List; the large specimen is from a collection made near Hillingdon in Norfolk in 1880.
