Spheridium 1 mm in diameter, globose, leathery brovoi colored, 

 slightly v;arty, because of the fine papillae; stipe flexuosus slender, 1 

 cm. long, erect, covered at the base with \';aiite silk- like hyphae, asco- 

 spores straight, filiform, 50|i in length.

In jtate summer and well into v/inter characteristic fungous 

 grov/ths are often seen protruding from the basal, ovulate, portions of 

 the spLlce, Sometimes nearly every sjilelet is affected. The structures 

 are wliite from 12 to 20 mm. long, and about 2 to 3 mm thick. Toward 

 their tips they may be browned and more shrunken than in regions near 

 their bases. Exsjnination of the affected spikelets show the seed to be 

 absent and their place to be occupied by \Tihite sclerotia approximately 

 the shape of the seed of the host. In general, the appearance is Ihat of a 

 eiaviceps sclerotitun except that it is taiite and soft, the protruding 

 horn being the remnant of the summer stage. 



Throughout the early part of the season the protruding part 

 bears myriad-S of straight to lunulate spores, showing strong resemblance 

 to the ordinary lunulate Fasarium spore.
