Sclerotia formed in the inflorescence of various grasses and 

 sedges, at first consisted of a soft mass of mycelium which pro- 

 duces conidia often accompanied with a saccharine fluid, at 

 maturity hard, subglobose subcylindric or horn-shaped, purplish- 

 black externally, white within ; stromata developing from scler- 

 otium after a period of rest, consisting of a sterile stem and 

 fertile head ; head subglobose, grayish, reddish-brown, or yellowish 

 margin often partially free ; perithecia flask-shaped, immersed in 

 the stroma or with the necks slightly protruding; asci cylindric, 

 usually capitate, 8-spored; spores filiform, nearly as long as the 

 ascus simple, hyaline.
