268 Mycetozoa of North America 



broken away. CapilHtium of numerous slender, brownish yellow 

 threads 1.5-2 n diam., simple or sparingly branched and anasto- 

 mosing, often dividing into slender branchlets at their origin or 

 insertion, nearly parallel, straight or flexuose, running from the 

 base to the upper part of the wall. Spores in mass brick-red, at 

 length brownish yellow, pale yellow by transmitted light, min- 

 utely warted, 8-10 ix diam. 



Type locality: Maine. 



Habitat: On dead wood. 



Distribution: Colorado, *Maine, Ontario. 



Illustration: Lister, Mycetozoa ed. 3. pi. 191, figs. a-c. 



An exceedingly rare species. The original collection was 

 made by F. L. Harvey in Maine, in 1889. It was found again 

 by Dr. W. C. Sturgis in Colorado, in 1913, and the latest collection 

 was by Mr. Eli Davis in Ontario, in 1939. No other records 

 appear except from Great Britain. It should be searched for in 

 higher latitudes and altitudes.

Plasmodium? Sporangia sessile or short-stalked, solitary or 

 in small clusters, subglobose or pulvinate, 1 to 1.5 mm. diam., 

 grayish pink, shining with iridescent green or coppery reflections; 

 sporangial wall membranous, thin, translucent, pinkish gray. 

 Stalk short, pale, enclosing granular matter, 0.1 to 1 mm.(?) high. 

 CapilHtium of abundant pinkish gray straight or flexuose threads 

 radiating from the thickened floor of the sporangium, branching 

 and anastomosing, attached by slender branchlets to the outer 

 walls; stouter below, becoming very slender in the upper part. 

 Spores in mass pale grayish pink, minutely and closely warted, 

 8-12 II diam.
