20-30 » long; conidia terminal, compressed, elliptical, 4-444X%3 pL 
when viewed in front, 4-414 1% when seen edgewise. 
The sporodochia resemble Cylindrocolla, but the structure is 
that of Dendrodochium. 
HeExicosoporium pitosum E, & E. 
On decaying wood, Louisiana. (Langlois, no. 2453.) 
Fertile hyphae erect, simple, septate, tapering above, straight 
or nearly so, 200-400 long, 5-6 thick below, forming a thin 
grayish-black pilose coating on the surface of the wood; conidia 
filiform, hyaline, nucleate, forming about 3 coils which incline to 
straighten out, about 214 thick and about 100» long, arising 
from small (3), hyaline subglobose lateral tubercles on the 
hyphae. 
Allied to H. fuscum Morgan, but that has the thread of the 
conidia thicker and a greater number of coils. 
CYLINDROCOLLA BIGELOVIAE E. & E. 
On dead stems of Bigelovia, Golden, Colorado, Jan., 1897. 
(Bethel, no. 177.) 
Sporodochia gregarious, depressed-hemispherical or strongly 
convex, yellowish amber-color, %~—34 mm. diam.; sporophores 
dendroidly branched, filiform, hyaline, 50-60X1 2; conidia termi- 
nal, catenulate, cylindrical, 6-714 p. 
DENDRODOCHIUM HELOTIOIDES E. & E. 
On dead bark of Kukiu tree, Sandwich Islands (Kauai), 1895. 
(A. A. Heller, no. 2678.) 
Sporodochia seriately erumpent through cracks in the bark, 
crowded, subconfluent, of irregular shape, orange-yellow, finally 
concave-discoid, the disk deep orange, the sides whitish; sporo- 
phores sparingly branched, erect, slender, 30-40 » long; conidia 
oblong-elliptical, hyaline, 5-7X2%4-3% p. 
Bears a striking resemblance to crowded forms of Helotium 
citrinum (Hedw.) Fr. ae 
FusARIUM ALEURINUM E. & E. 
On wheat flour spilt on the ground and left exposed four 
months, Nuttallburg, West. Va. (LL. W. Nuttall.) 
Sporodochia compact, subtuberculiform-effused and subcon-— 
fluent, reddish-orange, mycelium white ; fertil hyphae erect, much 
branched, branches erect ; conidia terminal, fusoid, slightly curved, 
continuous or faintly 1-3-septate, nucleate, 35-45X21%4-3
