Stromata solitary or very rarely cespitose, consisting of a slender, sterile stem and an 
enlarged, clavate, fertile head; stem olivaceous, longitudinally striate, becoming very dark~ 
colored in dried specimens, sending out numerous branching root-like fibers which sur- 
round the substratum and extend for some distance into the surrounding soil ; head clavate, 
much enlarged, tapering often both above and below, dark-brown, becoming nearly black 
in drying and roughened by the protruding perithecia; perithecia thickly scattered, 
immersed or slightly protruding ; asci very long, often 300 #, and 8-10 # in diameter ; 
spores filiform, nearly as long as the ascus, many-septate and often breaking up into seg-
