 Badhamia hyalina (Pers.) Berk. Trans. Linn. Soc. 21: 153. 1853. 



Plasmodium chrome-yellow (Lister). Sporangia more or less 

 clustered, usually sessile, globose or piriform, 0.5 to 1 mm. diam., 

 grayish white; sporangial wall hyaline, with scanty deposits of 

 lime-granules. Stalk when present short, yellowish, membra- 

 nous. Capillitium a network of fiat bands with broad, thin 

 expansions at the angles, evenly and sparsely charged with white 

 lime-granules. Spores purplish brown, adhering in firm clusters 

 of 8 to 20, more strongly warted or spinose on the outer surface, 

 11-13 IX diam. 



Type locality: France.

This species forms small colonies, often on piles of dead wood 

 and associated with other species of Badhamia. Together with B. 

 papaveracea and B. popuUna it comprises a group of related species 

 having spores firmly adherent in clusters. The spores are not as 

 dark as reported in European specimens and, generally, there is 

 considerable variation in the color of the spores of this and the 

 related species, and also in the group centering around B. utricu- 

 laris. Several European varieties are as yet unknown from 

 North America.
