3. Spermoedia cinerea (D. Griff.) Seaver. 
Claviceps cinereum D. Griff. Bull. Torrey Club 28: 240. 1901. 
Sclerotia clavate, gradually tapering upwards, straight, curved, twisted, or contorted, 
1.5-3 em. long and 1.75-2.5 mm. thick at the base, very viscid while developing, the 
base permanently invested by the flowering glumes of the host which are smooth, shining, 
black and closely adherent, smooth as far as covered by the glumes, reticulate for some 
distance: above, the -reticulations gradually disappearing above and merged into closely 
placed, longitudinal striations which disappear near the apex where the surface is nearly 
smooth or irregularly roughened, dark-gray at the base, gradually fading to very light-gray 
or almost white at the apex; stromata erect, erumpent ; stem cylindric or slightly fusi- 
form, short, stout, almost white; head slightly flattened below and overlapping the upper 
end of the stalk, 2-3 mm. in diameter, light-gray, almost smooth, viscid, covered with 
small, darker points indicating the position of the perithecia ; perithecia immersed, ovoid 
or subovoid, 190-225 < 60-904; asci narrowly cylindric, slightly narrowed below into a 
rather long, stout pedicel and slightly enlarged at the point of attachment, 135-150 X 4-Sy. 
Growing on the inflorescence of species of Hilaria.

longitudinally striate; stromata not seen in American specimens.
