 a stout thick base and a cord-like root. Cortex a thickish floccose 

 layer, with coarse warts or spines above, whitish then ochraceous or 

 finally brown, at length breaking up into areola which are more or less 

 persistent; inner peridium thick but fragile, thinner about the apex, 

 where it finally ruptures, forming a large irregular lacerate aperture. 

 Subgleba occupying nearly half the peridium, cup-shaped above and a 

 long time persistent; mass of spores and capillitium compact, farina- 

 ceous, greenish-yellow or olivaceous, becoming pale to dark-brown; the 

 threads very much branched, the primary branches two or three times 

 as thick as the spores, very brittle, soon breaking up into fragments. 

 Spores globose, even, 4 4.5/1* in diameter, sessile or sometimes with 

 a short or minute pedicel.
