and almost smooth, but they vary much in color and markings in 

 other gatherings. There are many developments with darker 

 and more spinulose spores, not paler on one side, which are there- 

 fore not var. heterospora. A specimen from Ontario (N. Y. B. G. 

 no. 8921) has dark and spinose spores like those of B. macrocarpa, 

 but the reddish hypothallus is present. The cotype of Fhysarum 

 nudum Macbr. is a limeless form of B. panicea having the reddish 

 bases and reddish stalks, with clustered, angled sporangia. Such 

 forms are found occasionally associated with normal sporangia.

Plasmodium? Sporangia white or pale ochraceous, smooth or 

 rugulose, subglobose, up to 0.5 mm. diam., or forming irregular 

 or branching plasmodiocarps, crowded or scattered; sporangial 

 wall thick, but friable, with dense deposits of lime-granules. 

 Capillitium white, fragile, consisting of an irregular network of 

 tubes filled with loosely adhering lime-granules, usually uniting 

 to form a pseudo-columella at the base of the sporangium. 

 Spores free, purplish brown, smooth, shining in mass, ellipsoid, 

 10 X 8 to 16 X 10 /i, traversed lengthwise by a ridge or fold 

 marking the line of dehiscence. 



Type locality: Poland. 



Habitat: On old straw, manure, rabbit dung, and dead wood. 



Distribution: Colorado, Massachusetts, New York, Ontario, 

 *Pennsylvania.

A conspicuous little species forming large colonies. It has 

 been found repeatedly by Mr. Eli Davis, on manure in a green- 

 house at Byron, Ontario. It resembles phases of Fuligo cinerea, 

 and is found on similar habitats, and often associated. It may 

 be recognized by the appearance of the spores in mass. The 

 spinose spores of F. cinerea appear dull, and the smooth spores of 

 B. ovispora shine by reflected light.
