coming pallid brown, up to 2in. (5 cm.) diameter, elliptical, obconic or sub-

white spines united at their apices, immixed with numerous sim.ple spines and

endoperidium ochraceous or bay brown, dehiscing by a definite apical stoma, later 
the whole lof the apical portion falling away; sterile base occupying the lower 
third of the peridium, of large cells, bay- or umber-brown, separated from the 
gleba by a well-defined diaphragm. Oleba yellowish, becoming pallid olivaceous;

often forming rings in pastures. — Cunningham. South Australia — Adelaide, Beau-
