5. C. tenella Schrad. Sporangia gregarious, globose, 0.6mm. in diam., 
yellowish brown, stalked. Cup one-third the height of the sporangium or 
much reduced. Net regular, with numerous prominent dark brown rounded 
nodes connected by four or five very slender threads and with a few free 
rays. Spores yellowish brown, nearly smooth, 5 to 6mmm. in diam. 
Common. 
6. C. aurantiaca Schrad. Sporangia gregarious, globose, 0.4 to 0.7mm. 
in diam., brown, stalked. Cup one-third the height of the sporangium, the 
margin irregularly and deeply toothed. Nodes of the net broad, flattened, 
angular, with the angles continued into the slender connecting threads and 
often into a few free rays. Spores yellowish, smooth, 5 to 6mmm. in diam. 
(Miami Valley—Morgan), (Ohio—Macbride). 
7. C. splendens (Schrad.) Pers. Sporangia scattered, globose, 0.3mm. 
in diam., brown, stalked, erect or inclined. Sporangium wall consisting in 
the lower half of about nine free ribs with little trace of a persistent cup, 
continued into a loose net with small, often triangular, nodes. Stalk slender, 
brown, four or five times the length of the sporangium. Spores pale, 
almost smooth, 5 to 6mmm. in diam. 
Cuyahoga Co. 
8. C. languescens Rex. Sporangia scattered, globose, very small, .25 
to .35mm. in diam., reddish brown, stalked, drooping. Cup one-third the 
height of the sporangium, reddish brown, shining, minutely striated with 
granular lines; the margin toothed. Nodes of the net dark brown, poly¬ 
gonal, with slender connecting threads and a few free rays. Stalk very 
slender, subulate, brown. Spores pale red, nearly smooth, 5 to 6mmm. in 
diam. 
Apparently rather common. 
9. C. purpurea Schrad. Sporangia gregarious, globose, 1mm. in 
diam., reddish purple, stalked, erect or inclined. Cup one-third the height 
of the sporangium with a deeply toothed margin. Net of slender threads 
with irregular meshes, and few expanded nodes. Stalk slender, furrowed, 
1.5mm. long, purple black. Spores purplish, nearly smooth, 5 to 6mmm. 
in diam. 
(Ohio—Macbride). 
10. C. elegans Berk, and Curt. Sporangia gregarious, globose, 0.3 to 
0.4mm. in diam., reddish purple, stalked, erect or inclined. Cup one-half 
the height of the sporangium with a deeply toothed margin. Net of 
slender threads connecting numerous flat expanded and branched nodes. 
Stalk slender, smooth, dark. Spores pale violet, nearly smooth, 5 to
