20 Mycetozoa of North America 



iridescent; sporangial wall with scanty lime deposits, often absent. 

 Capillitium a network of slender strands filled with white lime- 

 granules. Spores free, rarely loosely clustered, violet-brown, 

 minutely spinulose, 8-11 (jl diam. 



Type locality: Wanstead Park, Essex, England. 



Habitat: On leaves, straw, twigs, etc., also on wood. 



Distribution: California, Iowa, Massachusetts, New Jersey, 

 New York, *Ontario, *Oregon, Washington.

This species has been found repeatedly on Long Island, New 

 York, in large developments. It is allied to B. utricularis, but 

 the stalks are much shorter, firmer, often more grayish, and 

 each carries but a single sporangium. The more frequent habitat 

 is on herbaceous ground remains, although it also occurs on dead 

 wood.

Didydiiim magnum Peck, Rept. N. Y. State Mus. 24: 84. 1872. 



Plasmodium yellow. Sporangia globose, obovoid, or ellipsoid, 

 normally about 1 mm. diam., bluish, iridescent, clustered on long, 

 yellow, slender, branching, membranous stalks, 5 mm. or more 

 high; sporangial wall with scanty deposits of lime. Capillitium 

 a network of slender strands charged with white lime-granules. 

 Spores free, globose, usually dark purplish brown with a paler area 

 of dehiscence, minutely spinulose, 9-12 /x diam. (Plate 6, Fig.

Type locality: Center, New York. 



Habitat: On dead wood; not uncommon. 



Distribution: Colorado, Maine, Massachusetts, *Minnesota, 

 New Hampshire, New Jersey, New York, Ontario, Oregon, Penn- 

 sylvania, Quebec.

This species is related to B. utricularis but can be distinguished 

 by the more robust sporangia on longer stalks, and the spore dif- 

 ferences of color, fainter markings, and pale area, when present. 

 The spores are sometimes paler, as in B. utricularis, and this is 

 true of the type specimen of Peck, in the New York State Mu- 

 seum, which is not perfectly developed, and appears to have 

 formed during rain.
