meshes from 15/a to 60/a. The spores are brownish, minutely 
roughened, 7-8/a in diameter. 
We have one collection, made near Wausau, in the summer of 
1894.

Maebride: ‘ 1 Sporangia in clusters, close packed and erect, not 
spreading, bright ferruginous prior to spore dispersal, cylindric, 
stipitate, of varying height; stipe jet black shining, about one- 
third the total height; hypothallus generally well developed; 
columella black, gradually tapering, at length dissolving in cap- 
illitial threads and net some distance below the diminished plu¬ 
mose apex; capillitium of fuscous threads, the inner network of 
sparingly united branches uniformly thickened, the surface net 
composed of small, regular, polygonal meshes, the peridial pro¬ 
cesses few: spore-mass bright ferruginous, spores by transmitted 
light pale, almost colorless, smooth, 5-7/a. The species as now 
constituted includes forms varying in size from 2.5-25 mm.” 
Lister: “Plasmodium white. Total height 7-12 mm. Sporan¬ 
gia cinnamon-brown. Stalk 3-6 mm. long, arising from a mem¬ 
branous hypothallus. Capillitium as in S. fcmiginea, but the 
superficial net has rounded, more regular meshes, 5-10/a in di¬ 
ameter, and the threads of the meshes are often rather stout. 
Spores 4-6y in diameter. ’ ’ 
My specimens do not agree entirely with the above descriptions, 
but neither do they agree with that of S. ferruginea. The 
sporangia are from 7-12 mm. tall, but the stems are not over 
one-fourth the entire height. Many nodes of the inner network 
are broadened somewhat. The meshes of the outer net are not 
regular, and they vary from 5-14/a in diameter. The other char¬ 
acteristics, how r ever, leave this species, without doubt, where I 
have placed it. 
One of my specimens was found growing upon much decayed 
wood in Madison, October 1901, one was found upon bark near 
Tomahawk, and a third upon wood near the Whirlpool rapids of 
the Wisconsin, in the summer of 1893.
