28 THE MYXOMYCETES 



This resembles Badhamia decipiens except for the clustered spores, 

 and the more commonly aggregate habit. The spores, as usual when 

 clustered, are conspicuously warted on the outer side, as noted by 

 the author of the species. In a collection from Isle Royale, Mich. 

 (Univ. Mich. Herb. Fl. 125) the peridium is double, the outer crustose 

 layer splitting away from the membranous inner layer and tending to 

 expand in petal-like lobes. 



Michigan, Colorado, Montana, Oregon, California, West Indies, 

 South America; Ceylon, various parts of Europe. 



Var. reticulata G. List., Trans. Brit. Myc. Soc. 5 : 71, 1914, forming 

 simple or netted plasmodiocarps on moss on the trunks of living trees, 

 occurs in Iowa, the West Indies and in the old world.

1894. Badhamia hyalina (Pers.) Berk. var. papaveracea Lister, Mycetozoa 30. 



Sporangia gregarious, globose or ovate, 0.7-1 mm. in diameter, 

 stipitate, iridescent-gray; peridium thin, translucent, and containing 

 but little calcareous deposit, smooth or slightly rugulose; stipe very 

 short, but generally distinct, black or very dark brown; hypothallus 

 none; capillitium a network of large meshes with expanded nodes, 

 prominent, white, persistent after the spores have been blown away; 

 spore-mass deep brown; spores pyriform, adherent as in B. capsulifera 

 and about the same size, 10-12.5 fx, but even more strongly warted or 

 echinulate on the exposed sides. 



Distinguished by its short, dark stipe and adherent spores. 



Not common. New England to South Carolina, Alabama, Wisconsin 

 and Iowa; Rumania, Japan.
