8. B. lilacina Rost. Sporangia clustered, subglobose, about 0.5mm. 
in diam., smooth, pale or lilac colored, generally sessile. Capillitium a light 
colored dense network with angular nodes, calcareous thruout. Spores 
dark purple brown, very rough or reticulated, 10 to 15mmm. in diam. 
Summit Co. (Miami Valley-Morgan). 
9. B. rubiginosa (Chev.) Rost. Sporangia gregarious, obovoid, 0.5 
mmm. in diam., reddish or purplish brown, stalked, sporangium wall darker 
and more persistent below. Stalk erect, smooth, purplish brown, extend¬ 
ing into the sporangium to more than half its height as a prominent 
columella Spores dark purple brown, minutely roughened, 12 to 14mmm. 
in diam. 
Summit Co. (Miami Valley—Morgan), (Licking Co.—Oberlin College 
Herbarium). 
Var. 1—dictyospora Lister. Spores prominently warted or reticulated. 
Hocking Co. 
2. FULIGO. Haller. 
Fuligo septica (L.) Gmel. Plate 1, Figs. 4, and 4a. 
Sporangia irregular, interwoven, combined into a cushion shaped 
aethalium. The outer layer of sporangia is without spores and is densely 
charged with lime forming a cortex. Capillitium of hyaline threads 
generally branching and forming a network, containing large lime knots. 
A. Spores spherical. 
B. Spores nearly smooth, 7 to lOmmm. 1. F. septica 
B. Spores spinulose, 10 to 12mmm. 2. F. muscorum 
A. Spores ellipsoidal, spinulose. 3. F. cine7'ea 
1. F. septica (L.) Gmelin. Aethalia from one to many centimeters in 
diameter, 1cm. or more in thickness, yellow, brown, or gray, cortex 
abundant or sometimes scanty. Capillitium a loose network of hyaline 
threads with expanded nodes and containing fusiform or branching yellow, 
sometimes white, lime knots. Spores violet, nearly smooth, 7 to lOmmm. 
in diam. 
Common everywhere on logs and stumps. 
2. F. muscorum Alb. and Schwein. Aethalia small, 2mm. to 5mm. in 
diam., yellowish gray, cortex scanty. Capillitium of numerous irregular 
orange lime knots connected by hyaline threads. Spores violet brown, 
spinulose, 10 to llmmm. in diam. 
(Miami Valley—Morgan), (Ohio—Macbride). 
3. F. cinerea (Schw.) Morg. Aethalia elongated scattered or gregar¬ 
ious, usually covered with a smooth white cortex. Capillitium of large 
white lime knots connected by hyaline threads. Spores violet brown, 
spinulose, ellipsoidal, 14 to 16x11 to 12mmm. in diam. 
Erie Co. (Lorain Co.—Oberlin College Herb.), (Ohio—Macbride) 
(Ohio—Lister).
